January March 2016 1 The most common overuse injury that leads to the dis charge of new military recruits is a stress fracture. 1 Stress fractures are associated with abrupt changes in physical activity level, such as the increase in activity some recruits are exposed to as part of military basic training. 1 Stress fractures result from repetitive, sub maximal loads on normal bone that cause bone forma tion to lag behind bone resorption, leaving bone prone to microtrauma. 2 A subset of stress fractures, subject to high tensile forces and limited vascularity, are prone to delayed healing and are at risk for complete fracture, de layed, or nonunion, and require a more aggressive treat ment approach. 3 One of the high-risk stress fractures is of the lateral femoral neck which risks osteonecrosis of the femoral head, the need for arthroplasty, and perma nent disability. 4,5 Early surgical intervention for these high risk stress fractures is recommended to prevent fracture progression. 3-5 The cost of a recruit sustaining a femoral neck stress fracture that requires surgery is estimated to exceed $100,000 per injured recruit. At performed in about 25% of cases of femoral neck stress fractures. 6 Femoral neck stress fractures make up less than 10% of all stress fractures. 4,5,7-10 These injuries are most com mon in female military recruits. 2,7 Overall, complica tions occur in 10% to 40% of all femoral neck stress fracture patients. Complication rates increase with dis placement and varus surgical reduction. 11 Both intrinsic and extrinsic factors have been associated with an increased risk of femoral neck stress fracture. Extrinsic factors may include the type of physical activ ity, prior training regimens, footwear, and environment. 7 Intrinsic factors include sex, bone density and size, mus cle size, foot shape, leg length, and hip geometry. 5,7-9,12 Hip geometry is an important intrinsic risk for stress fractures. Clinically, loads in the average loading direc tion will not cause a fracture, but loads of extreme mag nitude or extreme orientation may. 13 In cases of altered femoral neck geometry, the joint load orientation be comes more vertical with coxa valga and more horizon tal in coxa vara. 13 shaft angle of less than 120, coxa valga as an angle of greater than 140 average femoral neck shaft angle rang es from 125 to 131. 13 Femoral neck stress fractures are associated with coxa vara 14 and compression side femo ral neck stress fractures are more common. 3 The treatment of femoral neck stress fractures should trinsic factors. Treatment of most compression side fem oral neck stress fractures involves not bearing weight on the affected extremity for 6 weeks. 3 Compression Correlation Between Femoral Neck Shaft Angle and Surgical Management in Trainees With Femoral Neck Stress Fractures CPT Robyn L. Chalupa, SP, USA MAJ Jessica C. Rivera, MC, USA CPT David J. Tennent, MC, USA LTC (P) Anthony E. Johnson, MC, USA ABSTR A CT The most common overuse injury leading to medical discharge of military recruits is a stress fracture. One of the high-risk stress fractures is of the lateral femoral neck which risks osteonecrosis of the femoral head, the need for arthroplasty and permanent disability. To prevent fracture progression early surgical intervention is recommended. Surgical repairs are performed in about 25% of cases of femoral neck stress fractures at mili tary treatment facilities. Hip geometry is an important intrinsic risk for stress fractures. Loads in the average loading direction will not cause a fracture, but loads of extreme magnitude or extreme orientation may. The purpose of this study was to determine if, in the presence of femoral neck stress fracture, there is a correlation between femoral neck shaft angle, surgical treatment and outcomes. The results of this study suggest there is no correlation between return to full military duty rates, treatment, femoral neck shaft angle or fracture grade have surgery. Individuals who did not return to duty tended to have higher pain scores at initial evaluation.


2 side stress fractures that show chronic changes such as cysts or intramedullary sclerosis involve more than 50% of the neck on MRI, and those that are complete may 1,2 Sariyilmaz et al used coxa vara and the resulting mechanical abnormality as an ad ditional indication for surgery. 15 Tension side femoral neck stress fractures should be treated with increased vigilance to prevent progression to complete fracture. 2,8 Nondisplaced stress fractures can be treated with can displaced fractures would require dynamic hip screw placement or arthroplasty. 15 The purpose of this study is to determine if, in the pres ence of femoral neck stress fracture, there is a correla tion between femoral neck shaft angle, surgical treat ment, and outcomes. METHODS After approval from the MTF Institutional Review Board, we performed a retrospective study. Patients that had been evaluated by orthopaedics, had imaging of the hip, and diagnosed with a femoral neck stress fracture at the MTF between June 1, 2012 and May 31, 2014 were included. We reviewed hospital and clinic records and available imaging data from surgical scheduling, elec tronic medical records, and the Picture Archive and Communication System (PACS) application. A potential subject list, shown in Table 1, was compiled using an electronic medical record search of ICD-9 codes which correspond to stress fractures of the femur, hip, and pelvis. Imagery available in PACS was reviewed to ensure the potential subjects did, in fact, have a femoral neck stress fracture and the necessary imaging studies were available for analysis. We then screened the poten tial subject list for other inclusion and exclusion criteria, shown in Table 2. Each subjects femoral neck shaft angle was measured on the anteroposterior radiograph by calculating the angle formed by the intersection of a line bisecting the midpoint of the femoral neck and the midpoint of the femoral head, and the anatomic axis of the femur, illus trated in the Figure. Each subjects MRI was then exam ined in order to grade the severity of the femoral neck stress reaction as indicated by bone edema and a frank fracture line (Table 3). Each subjects electronic medical record was examined for details on the clinical course, provider recommended activity restrictions, and ability to perform full military duty. Each subject was searched on the surgical schedule to determine whether they un derwent surgery for a femoral neck stress fracture. Comparisons among groups were then made using un paired students t test and Pearsons correlation for con tinuous data, and 2-tailed Fishers exact test for categori cal data. All analysis was performed using GraphPad Prism 6 (GraphPad Software, Inc, La Jolla, CA).

January March 2016 3 RESULTS Search of orthopaedic encounters within the electronic medical record found 205 uses of the queried ICD-9 codes in 185 individuals. Of those, diagnosis of femoral neck stress fracture was found in 72 individuals. Nine teen individuals were excluded from the study because an MRI was not obtained as part of their workup, they had been treated at their previous duty station, had pathologic fractures, were not active duty, or had no fracture on MRI. This left 53 individuals as study par ticipants, with 10 individuals having bilateral femoral neck stress fractures (63 total stress fractures). Review of the 53 included individuals found that all of the affected individuals were initial trainees, and 12 were male (23%). The average age of the included sub jects was 22.9 years (range 18 to 39 years) and there was no difference in age between male and female subjects ( P =.3820). Thirty of the 63 affected femurs were right side (48%). All of the evaluated femoral neck stress frac tures were compression side. One male presented with a complete fracture. Women had a greater mean femoral neck shaft angle compared to men (132.20.6 versus P =.0082). Normal is consid ered 125 to 131. No correlation existed among femo ral neck shaft angles, stress fracture grades, duration of symptoms, or pain scale results per hip. Ten subjects (8 female, 2 male) had bilateral stress frac tures. All bilateral stress fractures were noted on images obtained in a single encounter. In addition, the 7 pa tients who had surgical intervention for bilateral stress ing bilateral stress fractures did not affect surgery rates ( P =.1563) or return to duty rates ( P =.4639) compared to a unilateral stress fracture. operative patients. One 19-year-old patients course was complicated by chondrolysis and went on to total joint arthroplasty. Femoral neck shaft angles were not differ ent between subjects who were not treated with surgery (131.60.8) and those who underwent percutaneous P =.8759). However, sub jects with operatively treated hips had higher stress frac ture grades on MRI (3.40.1) versus subjects who did not undergo surgery (2.90.1, P =.0059). Subjects who underwent surgery also had higher mean pain scores on presentation to orthopaedics (4.80.5) versus subjects who did not undergo surgery (3.40.5, P =.0412). Two-thirds of surgical patients did not return to full duty (16/24), and 48% of nonsurgical patients did not return to full duty (14/29, P =.2660). There was no difference between femoral neck shaft angles among subjects who were able to return to duty (132.0 1.1) and sub jects who were not able to return to duty (131.20.6, P =.5081). Stress fracture grade was also not different be tween those who returned to full military duty (3.10.1) and those who did not (3.20.1, P =.4701). There was a did not return to duty having higher mean pain scores on presentation to orthopaedics (4.60.4 not return to duty versus 3.30.6 return to duty, P =.0575). CO MM ENT The results of this study suggest there is no correlation between return to full military duty rates and treat ment, femoral neck shaft angle, or fracture grade on pain level at presentation and lower return to duty rates. fracture grade and pain than those that did not have surgery. The femoral neck shaft angle was found to be more valgus in women. Additionally, the mean angle in this cohort was more valgus than the previously cited normal range of 125 to 131. 13 Bilateral stress fractures were found in 19% of study participants. In this study, all of the patients who had stress fractures were trainees. This suggests initial training places added stress on the femoral neck that either does not continue after conditioning or results in the attrition of trainees prone to these fractures. Individual preconditioning and dietary variance would affect how the trainee reacts to the increase in physical activities unique to initial train ing. The programs that have shown to decrease training injuries, such as command awareness, provider training, and the Army Physical Readiness Training (PRT) pro gram, should be continued. 6 This study found no tension-sided femoral neck stress fractures. This is not surprising because compressionportion of surgically-treated fractures was 49%. This percentage is greater than previously presented in the Table 3 Criteria table used to grade severity of the femoral neck stress reaction based on examination of the subjects MRI imagery.

4 literature (25%). 6 Although there was no statistically pain level, the stress fracture grade and pain level were higher for those operatively treated. While some litera ture supports treating compression side stress fractures with strict limitation of weight bearing, 3 our high opera tive rate is evidence that surgeon and facility consider ations play a role in management of this condition. For example, surgeons at this MTF must consider whether strict nonweightbearing is reasonable for individuals with training demands within the military environment. Clinically, providers should continue to have a high index of suspicion for femoral neck stress fractures in trainees presenting with hip pain. An MRI should be obtained if history warrants. When obtaining MRIs, the contralateral hip should be imaged to exclude asymp tomatic stress reaction in the contralateral hip. 3,17 Care should also include identifying and treating any intrin sic factors that put the trainee at risk for stress fracture. 3 Treatment may need to include supplementation with calcium and vitamin D, or treatment of women with low-dose estrogen. 8 However, not all intrinsic factors are amenable to intervention and focus must remain on 8 Ini prevention. 8 These could include progressive resistance training and protective exercises such as the forward lunge, isokinetic hip extension, one-legged long jump, 8,18,19 All retrospective studies have similar limitations includ ing those imposed by querying records that differ in quality. Not all data that was desired was recorded in every medical record. Many lacked record of pain scale, duration of symptoms, and duration of restricted weight bearing. This study was unable to assess for female athlete triad due to the lack of records on the patients menstrual cycle and diet. In post-hoc power analysis us ing Stata 13.1, we found we were adequately powered at 0.9519 for the comparison between return to full mili tary duty and those that did not with regard to mean femoral neck shaft angle. A follow up study to obtain a power of 0.80 would require 424 subjects, with 212 sub jects each in the surgical and nonsurgical groups, for the comparison between operatively treated hips and femo ral neck shaft angles. So while we were adequately pow ered with this sample size to examine some dependent variables, we were not adequately powered to examine all of them. A study of such size would not be possible at this single medical facility. CONCLUSION Both intrinsic and extrinsic factors contribute to stress fracture. Extrinsic factors may include the type of physi cal activity, prior training regimens, footwear and en vironment. 7 Intrinsic factors include sex, bone density and size, muscle size, foot shape, leg length, and hip ge ometry. 5,7-9,12 Those charged with training design should to prevent stress fractures. Future studies that prospec tively gather information on female athlete triad, meta sonal differences in rates would be useful. Studies that randomize surgical treatment may not be possible, but nonoperative treatment modalities involving treatment helpful in helping care providers choose the best treat ment to avoid the patients separation.

6 Millions of dollars are lost each year to the US military in medical discharges from injuries sustained in the ini tial training of recruits. According to the Government $390 million annually in the recruitment and training months of service. 1 Financial losses arise from the cost of initial recruitment; transport to the training location; uniforms and equipment; accommodation and rations; wages; instruction and supervision; administration; and are medically discharged. Each recruit who fails to complete training costs the military thousands of dol lars. and specialty. mises military readiness by reducing force strength and depriving the military of critical skills.

10 Unintended injuries, in particular physical training-re threats to US military readiness. 1 As many of these inju ries are considered preventable, this study was undertak en to help determine what additional information might contribute to reducing these injuries in the US Army. HISTORIC A L REVIEW Common musculoskeletal and orthopedic injuries (ie, strains, sprains, joint derangements, and stress frac tures) are the leading threat to the medical readiness of our troops. 1 Almost 50% of all service members experi ence one or more injuries annually. 2 Each year, these in juries limit physical ability and cause disability among active duty service members, resulting in millions of medical encounters, lost or restricted duty days, and medical expenses. 1,3-6 These injuries, predominantly of the back, knees, and lower extremities, are most often due to repetitive overuse, not from acute trauma. 1,3-5,7-10 In fact, over half of these injuries result from unit or per sonal physical training activities like running or sports. 2 Even during wartime operations, medical air evacua tions are more often for nonbattle injuries such as those caused by sports and physical training than for injuries resulting from combat. 11 This problem has persisted for decades. 12,13 In 1992, an estimated 450,000 outpatient medical encounters re sulted in several million days of restricted duty. 13 In 2012, 2.2 million Department of Defense (DoD) mili tary medical encounters resulted from these same types of musculoskeletal injuries, resulting in an estimated 25 million limited duty days. 1 The Army accounts for about 40%the largest portionof these days of lim ited duty. 1,4 It has been estimated that a 1% reduction in incidence of lower back pain could translate to the retention of thousands of trained Soldiers, avoidance of ings through fewer disability payments and less con sumption of medical care. 13 The continued high incidence of these common inju ries is, in part, because Soldiers must routinely conduct physical training. Physical training is the cornerstone formance. Yet physical training and optimizing human physical performance includes minimizing injury. Sci to identify risk factors and evaluate the effectiveness of some tactics for reducing these injuries. 14-19 Risks and interventions associated with running mileage, training programs, stretching, footwear, various braces (such as ankle, back, knee), gender, age, and medication use have been and continue to be investigated. In some cases, cations that could reduce injuries. In other cases, scien (IP) tactics once believed to be effective are actually helpful. In reality, some may increase injury risks. 3 Un fortunately, anecdotal information often drives risk pre vention decisions. SCOPE OF THIS EFFORT Investigators at the US Army Public Health Center (Pro visional)* (USAPHC(P)) theorized that a lack of aware ness and confusion about risk factors and effective persistent injury problem. In order to guide the develop ment of IP educational materials to increase awareness and correct misinformation, a voluntary survey tool was used to assess current awareness about IP topics and Army audiences. METHODS A group of health analysts, health educators, and stat isticians experienced with survey tools developed a What Soldiers Know and Want to Know About Preventing Injuries: A Needs Survey Regarding a Key Threat to Readiness Anna Schuh, PhD Formerly the US Army Public Health Command.


January March 2016 11 20 The survey, designed to be anonymous, focused on unintentional musculoskeletal in tions about heat and cold injuries. with the desire to limit the time bur den for respondents. Survey topics included demographics and job roles, personal injury history (past 12 months), awareness of injury effects, risk factors, interventions, leader ship perspectives (for nonsupervi sor responders), and IP interests (ie, activities, injury types, and infor mation sources and formats). Prior to disseminating the survey, docu mentation was submitted for review through the USAPHC(P) Human Protection Review Board. The collection of person established, broad categories provided in demographic The survey was delivered using the Vovici software application (Vovici is now Verint Enterprise Edition line survey was dispersed to Army audiences through several venues between July 9 and August 26, 2014 (6 weeks). Venues included postings on Army medical and nonmedical social media sites, websites, and emails. Posting of the survey link was vol untary for the proponent organizations. All responses were received in a protected data archive only accessible by selected project investigators. To assess general awareness of the problem, 4 evidence-based statements regarding most common musculoskeletal injuries within the Army and leading causes of these injuries were provided for respondents to indicate their level of agreement (on a 5point scale from Strongly Agree to Strongly Disagree). Respondents also scored the effects of vari ous risk factors and prevention measures for musculoskeletal injuries by indicating whether they believed the measures decrease risk, neither increase/decrease risk, increase risk, or whether the respondent was not sure. The correctness of statements were evalu evidence, 1,5,11 including a systematic review of physical training injury interven tion conducted by DoD experts. 3 In addition, respondents were asked to choose activities about which they were most interested in receiving IP information. Sixteen options (in cluding other) were provided with the instruction to select all that apply. Responders who were not healthcare providers/educators were asked 4 ences or beliefs regarding their lead erships support or interest in injury asking respondents about preferred format and venue for obtaining ad ditional IP information, and an open comments. free-text responses was completed by 2 investigators who separately reviewed all individual responses to de termine whether responses could be grouped with preestablished response categories or into any newly cre ated categories.

12 RESULTS General and Demographics The survey was initiated by 926 persons and fully com pleted by 685 respondents. The average time taken to complete the survey was 14 minutes. A comparison of the respondents who completed the survey (685) differences. Table 1 summarizes key demographic characteristics. (32%) responded. Very few responders were under 20 years of age, most falling between 21-50 years of age. Of the military respondents, almost half were of medi cal areas of concentration or military occupational spe cialties. Of these, the largest portions were physician assistants (32%), followed by physical therapists (18%). logical, radiological and nuclear specialists, infantry, military intelligence, ordnance, and others. Over half (53%) of respondents reported musculoskel etal injuries in the previous 12 months that affected their physical ability to do daily tasks or exercises. Of these, 61% were described as primarily associated with overuse. The most common cause reported was running (34%), as shown in Figure 1. Knowledge and Awareness in Table 2. The responses of all medical respondents (ie, healthcare/educator providers) followed the same trends as the overall trends for all respondents, with slightly more accurate answers and slightly fewer unsure re chose strong or very strong agreement with each of the 4 evidence-based statements regarding the general magnitude and types of the injury problem. However, 23% neither agreed nor disagreed. Respondents were less likely to identify correct for responses pertaining to musculoskeletal injury risk factors and interventions than for those pertaining to heat and cold injury (data not shown). Responses for risk factors that were most incorrect included the increased risks that are associated smoking. For interventions, higher percentages of incor rect responses were found regarding the effectiveness of ankle braces and cotton socks, and the lack of IP effec tiveness that has been shown with back braces, stretch wearing of minimalist running shoes. Injury Prevention Interests Figure 2 presents the types of activities about which respondents were most interested in receiving IP infor mation. Respondents chose an average of 5 activities (mean 4.98, SD 2.84). Despite some minor variations, activity interests were very similar between medical and nonmedical responders. 20 Write-in responses for other activities not listed included yoga, biking, and soccer. Sprains/strains/torn muscles and tendonitis/bur by both those personnel not in the health community (78% and 74%, respectively) and healthcare/educators (84% and 88%, respectively). Of next greatest interest to both groups were torn ligaments (56% for those not in the health community and 59% of those from health chronic conditions such as arthritis. A common topic appearing in free-text comments con Some respondents noted that because physical train ing is integral to optimizing Army readiness, Soldiers should be treated more as athletes and coaching or pro fessional guidance about injury prevention should be guidance concerning the prevention of re-injury. One suggestion made by a few respondents was to provide to participate in activities that are likely to result in reinjury. Of the 265 healthcare/health educator respond ers, 81% indicated that they would like products to help communicate information about risk factors and IP tac tics to their patients/customers. Perceptions of Leadership and Medical Roles The experiences or beliefs those not in the health com munity (providers and/or educators) regarding their lead erships support or interest in IP are shown in Figure 3. Only a slight majority (37% to 44%, depending on the statement) described positive leadership emphasis/sup port. Approximately a third (25% to 35%) had neutral perceptions and just under a third (22% to 32%) had neg ative views regarding their leaderships emphasis on and strongly with one another ( P <.01, correlation >0.74 to mately one-third of respondents provided an additional WHAT SOLDIERS KNOW AND WANT TO KNOW ABOUT PREVENTING INJURIES: A NEEDS SURVEY REGARDING A KEY THREAT TO READINESS

Many of my patients report injuries weeks/ months/years after the initial injury and the damage has been exacerbated from continued use. Teaching peo as a whole. Most of patients that I see are musculoskeletal due to overuse (overtraining). One of the biggest things I see is the leadership not taking care of their Joes and allowing them to modify their training according to their injury. Leaders need to be educated. They play a direct role in helping the junior Soldiers prevent and recover from injury. In many cases common sense is lacking.... with leadership. Some examples of such responses are shown below. Despite awareness of the magnitude of the musculoskeletal injury problem, free-text responses suggested that many believe that such injuries are inher ent to a Soldiers job, and are even a way to screen out Sergeants and First Sergeants. Responders indicated that this was necessary to change what was described as a suck it up and no pain is no gain attitude and to improve awareness about the negative effect of trainingguidance for reconditioning and recovery, especially af jury problem. Leaders were described as being unaware of the magnitude of the adverse impacts that uninten tional injuries have on the Army, and not recognizing what they can do to reduce these injuries.

January March 2016 15 indication of interest in this topic. Though the respon dents included civilians, the large portion of military personnel provides an indication of the knowledge and interests of the overall active duty Soldier population. This is supported in part by the similarities in the in jury experience of the respondents to prior studies of have shown that, like the survey respondents, about one half of personnel are injured each year, and that leading causes of these injuries include running, nonrunning ex ercise, and sports. 2,17,18 While most respondents demonstrated a fairly accurate awareness regarding the general magnitude of this Army injury problem, approximately one third either disagree or are neutral to acknowledgement of the documented evidence. This suggests a majority are aware of the prob lem. In addition, respondents indicated through free-text responses that there remains a common belief that these injuries are inherently part of the job and thus cannot be prevented. They indicate that part of this problem is many unit leaders may be unaware of the adverse im pacts that training-related overuse injuries have on Army readiness or how they can help reduce these injuries. The current level of awareness is further exacerbated by confusion about certain risk factors and effective ries among both nonmedical and medical respondents. Awareness of risk factors and interventions was greater for heat and cold injuries (not addressed in this article), and cold injury prevention training and strict account ability for such injuries. 23,24 Though the overall magni tude of musculoskeletal injuries in the Army is much greater than that of heat and cold injuries, current poli nually or at any level of a Soldiers basic, advanced, spe ported educational products are needed to increase the broader Army communitys knowledge of injury causes, risk factors, and the effectiveness of interventions. cal personnel to educate patients, and be straightforward enough for their patients (Soldiers) to understand.

16 Running Consistent with prior Army studies, 8,11,17,19 run ning was the most common cause of injury cited by sur vey respondents and was the IP topic of greatest interest. information about how to run correctly, evidence does on risk factors and guidance about proper conditioning and avoidance of over-training problems can be provid ed through educational materials. Weight-training and Extreme Conditioning Respondents also desired information regarding proper form and training and extreme conditioning. While some educa tion products can be developed to advise against certain trainers are recommended to give proper individualized instruction for these activities, especially for persons who have had prior injury. Agility, Cross-training, and Stretching recognized the importance of a mixed exercise program and desired additional information about cross training desired to explain different types of stretching tech when and how to incorporate them into a training pro gram. Road Marches About half of the respondents desired ad ditional IP guidance for minimizing injuries resulting tary training activity topic 25,26 may provide information for better educational products that describe key risk factors and injury types, with suggestions to minimize risks. Risk factors and Interventions survey, the topics considered of greatest importance are those for which the majority of respondents exhibited lowest awareness as indicated by incorrect responses regarding the degree of risk associated with risk factors and interventions. While future study of effective inter ventions is still needed, increased awareness of current evidence is warranted for topics such as: Body Type and Injury Risk under the incorrect impression that a thin body type does not affect injury risk, and another 6% thought that risk of injury, 9 will also increase risk to injuries especially stress frac tures. 17-19 Products should be developed to help dispel myths that thinner means healthier. Flexibility and Stretching Though evidence has shown risk of injury), 9,18,19 71% of respondents believed that most respondents (58% total, 41% healthcare/educators) consider stretching prior to exercise to be a means of to support this. 3 Current data is rather mixed. The com plexity of variables include different types of stretch ing (eg, static versus dynamic), different body types and 3,27-29 Given the unknowns, current expert guidance is to avoid static stretching prior to exercise and instead use audiences should be made aware of the variables and unknowns Footwear Responses show confusion regarding risks re sulting from use of cotton socks, minimalist shoes, and older running shoes. For example, the use of minimalist shoes (shoes with limited sole and zero drop heel to toe support) has been a popular trend in the past few years. While marketers have purported these shoes re duce injury risk, a majority of our survey respondents (58%) indicated they believe that minimalist shoes in crease the risk of musculoskeletal injury. Evidence does not indicate they increase or decrease risk of injury compared to other shoe types. 30,31 Products that clarify existing evidence and dispel myths on these topics are needed. Braces educators) considered back braces/belts to be a means of decreasing injury risk. However, substantial evidence indicates that they do not reduce risk, and both military policy and national guidance advise against their use. 3 This is especially important since concerns suggest a potential for increased risk due to use. On the other hand, the use of ankle braces to prevent injuries in bas ketball and parachuting has been strongly supported by 3,8,33-36 Products that clarify effective duction are needed. Enhancing Unit Leadership Awareness Essential elements of IP include leadership awareness, interest, and activity. 3 Consistent with prior evaluation, 13 the respondents in this survey pointed to leadership at the WHAT SOLDIERS KNOW AND WANT TO KNOW ABOUT PREVENTING INJURIES: A NEEDS SURVEY REGARDING A KEY THREAT TO READINESS


January March 2016 17 (especially with running) and marginalizing those who leaders, who have direct oversight of physical training, As many unit leaders may not be reached without a di rect mandate through their chain of command, respon authority to implement mandated training would help to effectively implement this recommendation. Medical Profile Improvements Based on responses from this survey and consistent with a prior study, 13 the lack of consistent documentation of reason that unit leaders ignore or marginalize those on a of consistency may also encourage misuse of the Army cannot address all Soldiers motivational differences, and inclusion of detailed rehabilitation and recondition ing procedures could improve the validity and credibil number of re-injuries and incidence of chronic injuries in what is a relatively young population. Limitations As it is not possible to determine the number of persons who were aware of the survey, response rates could not be estimated. A comparison of demographic data from this survey to that of the overall Army active duty popu lation (eg, 86.4% male, 13.6% female; source: Armed Forces Health Surveillance data, 2013) shows the lim ited sample of respondents is not a cross-sectional rep resentation of the Army. In addition, almost half of the respondents were from areas of concentration or mili tary occupational specialties related to medicine, which is a much more substantial representation than that of the overall Army. However, the medical respondents referred to problems and interests on behalf of their patients, which at least indirectly represent the broad er Army population. In addition, injury experiences of broader Army. 2,15-17 In addition, medical professionals CONCLUSION Considering the long-standing magnitude of a prob lem that has been documented for decades, awareness among Soldiers regarding physical training injuries and vey indicate that many personnel desire additional in educational materials can empower individuals to help reduce common musculoskeletal injuries in the Army. Products should address both knowledge gaps as well as topics of particular interest to the audience. To achieve a population-level reduction in injuries, improvements in leadership awareness and possibly even policy-level accountability are needed. Because lack of awareness among unit leaders may inhibit Army human perfor mance optimization, they should be a key audience for future IP educational efforts. The Army medical com munity can also become better partners with its opera tional and Soldier training counterparts. This includes mitigate the occurrence of re-injuries and ensure the most effective rehabilitation, as well as assisting with future IP awareness and education.

20 In 1970, physicians at William Beaumont Army Medi cal Center in El Paso, Texas, noted a series of 4 cases of sudden death in Army cadets associated with sickle cell trait (SCT). 1 Seven years later, Koppes et al 2 noted another 4 recruits, all with known sickle cell trait, were hospitalized for exertional rhabdomyolysis (ER) leading to myoglobinuric renal failure. These reports prompted further evaluation, leading to a military study which noted that among a total of 2 million recruits at army basic combat training, there was a higher incidence (40 times) of unexplained sudden death in black recruits compared to the general military population. In addi cruits with SCT was 30 times more common than black recruits without SCT. 3 this risk factor, patients in the military and athletic set tings with SCT continue to suffer injury and even death due to this underlying condition. 4-8 We report the case of a young, active duty SCT positive African American male presenting with exertional rhab domyolysis complicated by myoglobinuric renal failure delayed despite a typical clinical presentation and avail able SCT screening results. This case highlights the importance of the recognition of SCT as a risk factor for severe rhabdomyolysis, and suggests the need for a more robust and effective SCT screening program. CA SE REPORT In May 2015, a 26-year-old active duty African Ameri can male Army Soldier stationed in El Paso, Texas, experienced sudden severe leg and back pain while performing the Army Physical Fitness Test. Symptoms onset occurred after completing the pushup and sit-up portions. Cramping occurred while undergoing the 2-mile run and quickly progressed to such intensity that he was unable to ambulate, requiring a wheelchair for transport. He subsequently presented to an acute care clinic the following day and received Ketorolac 60 mg intramuscularly for intense back spasms prior to being released to home. Four days later, he presented to the emergency room for progressive cramping, nausea, and oral intolerance. Despite clinical evidence of rhabdomyolsis with clas cells), he was given a prescription of sulfamethoxazole/ trimethoprim for suspected urinary tract infection and discharged from the emergency room. The following day, he represented to the emergency room with worsening muscle pain, oral intolerance, and the new complaint of inability to urinate or defecate. On initial physical exam, the patient was found to have sig the lower back. No signs of altered mental status, as terixis, or paresthesia were noted on physical exam, and peripheral pulses were intact throughout. He denied any recent viral illness or prodrome. Initial laboratory eval CK of 37,069 U/L, serum urea nitrogen (SUN) 113 mg/ dL, serum Cr 13.6 mg/dL, AST of 704 U/L, ALT 424 U/L, and serum potassium of 4.4 mg/dL (most recently 4.2 mg/dL 2 years prior).

Although commonly a benign condition, numerous studies and case reports sudden cardiac death. We report a recent case of an SCT positive African American active duty male Soldier who suffered exertional rhabdomyolysis following an Army Physical Fitness Test. His course was complicated by acute renal failure requiring hemodialysis, and he eventually recovered renal function. The diagnosis was highlights the importance of the recognition of SCT as a risk factor for severe rhabdomyolysis, and suggests more must be done for an effective SCT screening program for the active duty military population.


January March 2016 21 pelvic CT-scan was performed showing mild right peri nephric stranding with no hydronephrosis or hydroure ter. The patient was subsequently admitted to the inter nal medicine service with a presumptive diagnosis of rhabdomyolysis-induced acute kidney injury. It was not until this time that the patients SCT positivity was doc umented while being evaluated for his acute complaints, despite positive screening history and family history of exertional rhabdomyolysis. initially received aggressive intravenous hydration, but uptrend in his serum urea nitrogen and creatinine levels. Hemodialysis was initiated on hospital day 2 for symp tomatic uremia manifested by asterixis and nausea. The patient underwent 5 sessions of hemodialysis with im provement of his clinical function, as well as laboratory At time of discharge, urine output was approximately 3 improvement in SUN (42 mg/dL), serum creatinine (4.6 mg/dL) and CK of (250 U/L). During admission, serum electrophoresis was ordered and would later be reported as 39.4% HgbS, 57.3% HgbA, and 3.3% HgbA2. The patient was seen in follow-up a month after his ini ment with a SUN creatinine to 18 mg/dL and 1.6 mg/ dL respectively. He is currently in the medical evalua tion board process for discharge in accordance with the provisions of Army Regulation 40-501 9 regarding exer tional rhabdomyolysis in the setting of known sickle cell trait requiring dialysis. CO MM ENT Sickle cell trait is an inherited, incompletely dominant hematologic disorder that causes red blood cell sick ling during low oxygen states. It is present in 80,000 to 100,000 Americans, with a presence in African Ameri cans at a rate of 8% to 10%. 10 The majority of individuals who are SCT positive experience no deleterious effect to their life span and often do not encounter medical com plications during exertion. Many cases have been re ported of sickle cell trait in athletes and military recruits for whom physical exertion results in severe medical morbidities such as rhabdomyolysis. 4,5,8 The incidence of SCT associated ER is unknown, the incidence of ER in military trainees is 22.2 cases per 100,000 trainees. 11 The precise mechanism of ER in SCT carriers is unclear. It has been speculated that the combination of severe hypoxemia, lactic acidosis, hyperthermia, and red cell dehydration that occur in muscles being exercised pre cipitates an environment in which red blood cells will sickle. Martin et al 12 produced evidence of this by show ing that exercise and physical exertion resulted in in creased sickling in venous blood when testing military recruits performing arm exercises. Another hypothesis is that increased sickling leads to vasooclusive crisis in the muscle that leads to muscle cell breakdown and injury. Injured muscle cells release cellular contents, including myoglobin into the blood stream. Myoglobin subsequently causes renal injury via renal vasoconstriction, formation of intratubular casts, and direct toxicity to the tubular cells of the kidney. 13 Patients serum creatinine kinase and serum creatinine trend during hospitalization.

22 In a recent study on the genetic polymorphisms asso ciated with ER, Deuster et al 14 corroborated the link between SCT and ER. However, they also noted that a causal pathogenic link remains unclear. The study indicates that, in contrast to an exertional sickling hy pothesis, SCT may instead be a surrogate for some other genetically linked risk, or, alternatively, part of a 2-hit phenomenon. The uncertainty of the precise role SCT has in ER is the foundation of an ongoing debate con cerning the premise of sickle cell screening. The American Society of Hematology (ASH) guidelines oppose universal screening for SCT, stating that it does not properly address the issues at hand and places a stig matization on SCT-positive individuals. 15,16 The associa tion instead supports administering universal precau tions to reduce exercise induced injury and heat-related injury such as those implemented by the US Army. The ASH policy of universal precautions and the omission of a requirement for SCT testing has also been supported by clinicians and some professional medical organiza tions. 16 Also of note, the ASH recommends increased research into the relationship of SCT with exertioninduced illness such as rhabdomyolysis before further policies are established. 16 The opposing view supporting testing for SCT notes that universal precautions are ineffective and further inter vention and screening is needed to properly identify this patient population. In 1996, the Department of Defense dropped its regulation requiring all military divisions to screen for SCT, leaving the decision to each military branch. The Army is the only branch that does not spe cautions with its recruits in an effort to reduce morbid ity and mortality. In the past 5 years, numerous studies recruits with SCT who suffered medical complications while undergoing strenuous exercise ranging from rhab domyolysis, compartment syndrome, and even sudden cardiac death. In the civilian sector; following the death of a college football player in 2010, the National Colle giate Athletic Association adopted a policy* of manda tory testing for sickle cell trait in all athletes who seek to participate in Division I athletics 15,17 a population similar to the active duty military population. Further, a recent (2012) study of approximately 2 million athlete years showed that the risk of exertional death of Division I football players with SCT was 37 times higher than those athletes without SCT. 18 These studies all describe medical conditions for which timely diagnosis and treat ment are imperative in improving medical outcomes. Our case report illustrates that despite universal precau tions for Army Soldiers, severe negative outcomes with exertion can occur in SCT-positive individuals. In fact, guidelines written by the Uniformed Services Univer sity Consortium for Health and Military Performance calls for referral of active duty military personnel with a concomitant diagnosis of ER and SCT to the medical evaluation board for review of their military status. 19 Sickle cell trait status is an invaluable clinical deter in SCT screening programs with emphasis on rapid incidence of adverse outcomes and ultimately improve patient care. This could be aided with a policy by which SCT status is made more apparent on patient medical records and hospital electronic medical records, such as alerts in past medical history or allergies. Sickle cell trait positive patients should not be given nonsteriodal cramping until after a workup for ER, including renal function assessment. Also, SCT screening tests should be easily accessible. Finally, all clinicians, including physician extenders, must be aware of the association of SCT and ER.

30 Combat extremity injuries frequently result in last ing disability. Recent publications from our Institution have helped delineate the nature of war wound sequalea, paedic-related disability. 1,2 Among those is the irrecov erable loss of skeletal muscle, or volumetric muscle loss (VML), which clinically can result in loss of motor pow er, fatigability, and cosmetic aberrations. 3 Animal mod els of VML indicate that strength loss after small VMLs (10%-20% loss of total muscle volume) is dispropor 4,5 Furthermore, loss of overlying muscle can adversely affect fracture healing because of multifactorial contributions skeletal muscle supplies to the fracture biology. 6-9 That VML is clini of wounded service members with Type III open tibia fractures who are medically retired from the military. 10 Currently, the loss of skeletal muscle is not a clinical target due to the lack of available therapies to address the volumetric defect and due to the clinical empha sis on bone healing rather than the overlying muscle the remaining skeletal muscle and limit the ability for the muscle group to optimally rehabilitate. This sup position is supported by limited clinical observations of patients with VML that present chronic functional therapy. 3,11,12 A preclinical rodent study demonstrated that VML-injured muscle strength can increase in re sponse to physical therapy (ie, wheel running). But no was observed, raising questions regarding the main tenance of plasticity of the traumatized musculature. 13 remodeling response after VML injury that may eventu ally exhaust the regenerative potential of the remaining portion of the injured musculature and lead to a progres sive further loss of function. Preclinical animal studies have documented some evidence of this potential condi tion, such as the prolonged presence of centrally located sion. 3,4,14 All told, growing evidence suggests that VML injury may present a progressive degenerative condition. Muscle-related Disability Following Combat Injury Increases With Time MAJ Jessica C Rivera, MC, USA Benjamin T. Corona, PhD ABSTR A CT Background: Combat injuries are most often to the extremities, resulting in a majority of long term disabilities be ing of orthopaedic nature. Some injuries are expected to improve with time. The Army Physical Evaluation Board (PEB) gives consideration for conditions that may improve with further care by placing eligible patients on a tem porary retirement list. While this may be appropriate for some conditions, injuries such as those to skeletal muscle can be irrecoverable. We aimed to examine combat injured subjects with known muscle injuries who were placed in temporary retirement status to determine if their muscle conditions improved. We hypothesized that muscle-related disability would not improve despite additional time for recovery. Methods: The PEB results of 33 combat wounded service members were reviewed to determine what individuals were placed in temporary retirement status. We compared what muscle conditions were present at each PEB exami also compared if the disability rating assigned to the muscle condition changed with time. Findings: of the subjects experienced improvement in their muscle condition as measured by disability ratings. Seven subjects initial exam. Two subjects have muscle disability ratings that were unchanged. Conclusions: While temporary retirement status provided opportunities for injured service members to experience additional improvement prior to permanent retirement, not all conditions can be expected to improve. This study demonstrates that the Army PEB ratings for muscle conditions did not improve despite additional recovery time being granted to the subjects on temporary retirement status.

January March 2016 31 Unfortunately, the natural history of an injured limbs function after VML injury is unknown. We aim to ex plore preliminary evidence on the natural history of VML injury by examining disability outcomes over time in a cohort of wounded service members with mus cle-related disability. We hypothesize that VML injuries result in deterioration of muscle function with time. METHODS This study was conducted in accordance with an Insti tutional Review Board approved protocol. We examined the Army Physical Evaluation Board (PEB) results of previously published cohorts of medically retired ser vice members to determine how disability designations for muscle injury change with time for service members who underwent more than one examination by the PEB. In brief, a 450 service member cohorts overall disability characteristics were published by Cross et al 1 and dis ability related directly to muscle conditions is described by Corona et al 10 for 36 service members (8%). Of the 36 individuals with muscle-related disability, 33 had docu mentation in their medical records describing the volu metric loss and persistent weakness, allowing us to con cause of their muscle-related disability. The disability designation itself is assigned by the PEB as any condi tion that detracts from an injured service members abil ity to perform his or her military occupational specialty signed a percentage rating which, on a spectrum from Once the PEB determines an injured service member ditions are enumerated and rated, the service member may be medically retired or separated from active duty. The PEB can also determine that the service members injury is not stabilized enough to determine to what In this case, the PEB expects that the illness or injury will improve with additional care and that the service assumption is that the condition will improve and the service member should not be separated or medically retired from active duty prematurely. In this case, the PEB places the service member on Temporary Disabil ity Retirement List (TDRL). The service member con tinues to get care for the conditions and is reevaluated periodically by the PEB to determine if the condition is is reached) or medical retirement/separation, the PEB signs each a disability rating. We examined the PEB database outcomes for the 33 cle condition to identify which subjects were placed on TDRL for any period of time prior to being medical retired. Because the assumption for TDRL placement is that the conditions in question may improve, we ex amined the changes in disability ratings for the muscle conditions between the initial PEB evaluations, iterative position at the time of each service members medical retirement. This allowed us to determine if, from the PEB evaluation standpoint, disabling muscle conditions by the assigned disability rating. The time between the evaluations was noted in an attempt to describe how VML injuries change with time in terms of increments of disability ratings. Comparisons between subjects with different PEB outcomes were made using students 2-tailed t test. Linear regression analysis was performed to determine if disability rating increased as a function of time postinjury. To perform regression analysis, pa tients who did not have a VML disability rating upon initial TDRL were given a disability of 0%. Statistical RESULTS tion. Their average age was 28.21.7 years (range 22-44 years) and median rank was E6 (range E4-O6). Combin all disability rating was 64% (range 20%-100%) and av erage individual disability rating for just the VML was 29% (range 0%-60%). The average time between their dates of injury and respective medical retirement was 681 days (range 246-995 days). Eighteen (55%) subjects were placed on TDRL during cal retirement. Their average age was 24.51.2 years (range 19-35 years) and median rank was E4 (range E4E6). Age was not different compared to service mem ation ( P =.0784) but service members placed on TDRL ( P =.0140). Their average overall disability rating com 20%-70%) and average individual disability rating for just the VML was 25% (range 10%-60%). The overall rating for service members who were medically retired


32 members placed on TDRL prior to retirement was P =.0463) but the disability rating assigned to the VML alone was not differ ent ( P =.5140). The average time between their dates of injury and respective medical retirement was 1,293 days (range 630-1,986 days). Because of the additional time allowed for maximal medical ration between date of injury and date of medical retirement ( P <.0001). Of the 18 service members that were placed on TDRL, 7 subjects with an initial muscle condition rating were granted a higher (more disabling) rat 40%], P =.0313). The charts in the Figure demon strate the increase in the disability ratings for each were not assigned a muscle-related disabling con dition at their initial PEB evaluation but went on All of these service members had a pain or loss of motion rating initially which was recognized as a muscle condition at their follow up evalua tion as shown in the Table. The remaining 2 ser vice members had VML disability ratings which did not increase or decrease between their initial ment dispositions, one with a 20% VML disability rating and one with a 30% VML disability rating. CO MM ENT These results indicate that, for a portion of service members with VML related disability following combat injuries, some are medically retired at on TDRL for a period of time prior to medical retirement. Despite the intent of TDRL which is to allow for improvement until maximal medical tions for service members placed on TDRL result in worsening VML disability. Sixteen of the 18 (89%) service members placed on TDRL either had an positions or were recognized to have a VML related dis at interval evaluations. Some differences existed between the service members and those who were placed on TDRL.

The contribution of VML to the overall rat ing was not different between the groups, suggesting that other injuries contributed in part to their medical retirement at their The VML disabling conditions of ser vice members placed on TDRL did not improve but rather deteriorated. This is anticipated for a number of potential rea sons. Volumetric muscle loss is not ad dressed during acute stages of care and, therefore, the remaining muscle mass is left to undergo continued degeneration and prolonged remodeling. 3,4 During this time, VML injury propagates extensive sively restricts range of motion. It is likely under this condition that the injured musculature exhib its reduced or disuse atrophy. Coupled with the clinical observations that physical rehabilitation of VML inju cle strength of the injured musculature, it is predictable that VML presents a deteriorating condition. Prospec pathophysiology of VML injured muscle. Limitations to our study include the use of the PEB dis ability designations as surrogates for true disability and our small sample size. The PEB ratings are assigned in accordance with the Veterans Affairs System for Rat ing Disabilities (VASRD), which at minimum provides a uniform guidance to how the PEB designations should be assigned. While every grading system contains some level of subjectivity, the VASRD guidance is enforced to attempt to minimize interrater differences. The PEB function or other true deterioration in clinical status. We used the PEB disability rating as a surrogate for wors ening muscle condition, however, because the ratings detracts from a service members ability to perform on active duty job. As such, we feel that the increased dis ability rating between time points for any given service member provides some measure of decreased functional status attributable to the VML. Finally, our small sam ple size may not allow us to make accurate statistical inferences. This is a limitation imparted by the avail ability of retrospective data. However, when taken in total with the overall description of the larger published cohort, this data adds to the granular detail of the longterm sequelae of extremity injury not found in a vast majority of descriptive studies on war injury. In conclusion, these data are consistent with growing body of preclinical literature demonstrating whole mus cle unit deterioration following VML injury. The natu ral history of VML in human subjects has not been de scribed. This is foundational preliminary evidence that the natural history of combat sustained VML injury is also one of deterioration.

MUSCLE-RELATED DISABILITY FOLLOWING COMBAT INJURY INCREASES WITH TIME


January March 2016 35 The Global War on Terror has left an indelible mark on Americans, particularly on US military personnel who have served on multiple overseas deployments. The me dia has highlighted stories of Soldiers with amputations, traumatic brain injuries, and posttraumatic stress dis order. The Armys response to ensure provision of total care for wounded Soldiers following serious injuries is the Warrior Transition Unit (WTU), a comprehensive program designed to house, rehabilitate, and return Soldiers to duty or foster a transition from military to civilian life. Occupational therapists have historically been agents of social change related to disability, and occupational therapy practitioners provide care at the WTU as part of an interdisciplinary team. An exami nation of the WTU provides insight into disability, and considerations of the WTU helps inform future practice. EST A BLISH M ENT OF THE WA RRIOR TR A NSITION UNIT In response to the recognition in 2007 of the extent of substandard care for wounded military personnel, 1 the Army established 35 WTUs at major bases in the conti nental United States and overseas to ensure the availabil ity of professional services for those Wounded Warriors. 2 The mission of the WTU is to heal and prepare [the Soldier] for transition, and it aims to accomplish this by providing each Soldier with a Comprehensive Transi tion Plan (CTP). 3 While working through the CTP, the Soldier has access to a system called the Triad of Care. This Triad includes a squad leader, a nurse care manager, and a primary care manager who is either a physician or physicians assistant. 3 The Triad is supplemented by an interdisciplinary team of occupational therapists, physi cal therapists, social workers, transition coordinators, and career counselors, among others. 2 The command structure of the WTU provides oversight and accountability. While assigned to the WTU, the housing, normal pay and allowances, and healthcare ser vices. The Soldiers daily responsibilities are to attend medical appointments, engage in therapy to learn new life skills, and seek career counseling to transition out of the military or to a new military occupational specialty, as appropriate for the Soldiers future plans. Active Duty, National Guard, and Reserve Soldiers who have sustained physical and/or mental health injuries while serving and who require at least 6 months of in tensive medical care are accepted into the WTU. A fact sheet published by the Warrior Transition Command 4 states that as of February 2, 2015, the majority (84%) of the 4,001 Soldiers remaining in the WTU have been deployed at some point, but only 167 were injured in combat. Currently, the WTU success rate of returning Soldiers to duty is approximately 45%. The WTU recog nizes that work is important to the Soldiers mental and physical well-being, therefore, returning the Soldier to a purposeful worker role is emphasized within occupa tional therapy treatment. EVOLUTION A ND AD A PT A TION cupations to restore mental and physical health are foun dational tenets of occupational therapy. One fundamen tal example of this is the moral treatment movement in Europe in the 18th and 19th centuries. That move ment marked a critical paradigm shift when individuals with mental illness began to participate in work tasks, or meaningful occupations, rather than being restrained. Adolph Meyer, the psychiatrist recognized as the fa ther of occupational therapy, acknowledged the link between meaningful occupations and overall health, an idea ahead of its time. 5 Since its creation and throughout its growth, occupational therapy has long been rooted in social justice, fostering cultural change related to dis ability. Presently, occupational therapy and healthcare provision continue to evolve within the WTU. As of 2015, the WTU has downsized from 35 to 25 units in operation with 11 Community Care Units, smaller units for Soldiers with less complex care needs which allow them to heal closer to home. 2,4 Fewer service War and Rehabilitation: Occupational Therapys Power to Transform Disability Into Ability 1LT Catrinna Amorelli, SP, USA 1LT Lindsay Sposato, SP, USA


36 members are deploying and returning with injuries as the militarys current presence and involvement in over ated the closure of select WTUs while ensuring no deg radation to the care and services provided to Soldiers and their families.* The WTUs at 5 regional medical commands have been designated for inactivation by Au gust 2016. Consequently, Soldiers within those WTUs will be transferred to other units.* As the WTU struc ture continues to evolve and downsize, there is an op portunity to critically evaluate it. LESSONS LE A RNED of the military unit structure which fosters unit cama raderie among Soldiers, the interdisciplinary team of healthcare providers, and the inclusion of the Soldiers family members in the plan of care. Despite the ben well. As shown in the inset, these include the potential that receiving a medical disability rating may incentiv ability may foster symptom exaggeration, and the mul tilayer administrative and clinical processes may cause extended lengths of stay, perhaps beyond the ideal time required for rehabilitation goals to be reached. The criticism that the WTU may create a climate that tive, since the language was purposefully written so the Soldiers would identify themselves as Warriors in tran sition. Regardless of intentions, Soldiers learn about the medical disability rating system and the fact that ad ditional diagnoses in their medical record can result in susceptible Soldiers to identify with their diagnoses, and even seek additional diagnoses to add to their medi cal disability claim. Occupational therapy practitioners who work closely with Soldiers vulnerable to identify ing with the sick role must be proactive. As creators of change, therapists can facilitate an incentive to recover and identify with ability rather than disability. APPE A L TO ACTION It is necessary to create a shift relating to the Soldier mindset that surrounds the disability rating system. Dis ability ratings by Veterans Affairs are assigned to Sol diers who have sustained injuries or diseases that are service-related, such as qualifying Soldiers receiving care within the WTU. 6 A disability rating is a percentage (0%-100%) assigned to a Soldier based on injury or ill ness severity. The higher the rating, the greater amount of compensation provided from the government. 6 In stead of promoting health, the system may inadvertently function. Reliance on a disability rating may provide a predictable, continuous income, but may also inadver to the system including the possibility of a lump sum disability payment (rather than a continuous payment), coupled with a release for all future disability claims, could effectively deter system misuse. After acceptance of a lump sum with a release, there may be less incentive for discharged Soldiers to revisit their disability claims and continue the cycle of dependence. As rehabilitation professionals within the WTU, occu pational therapists must hold themselves accountable for services rendered, as well as services withheld. Soldiers deserve compensation for injuries, but allowing Soldiers to advance towards a higher rating than warranted is a disservice not only to the Soldier, but to the ethical standards of the profession. The Army values and the occupational therapy code of ethics should be revisited frequently to regain focus for both Soldier and therapist. Occupational therapists can steer the rehabilitation para digm from the medical model to the social integrative model of disability. The medical model views disability as a negative occurrence, which can leave an individual dependent on supports and unmotivated to reintegrate into previous roles and responsibilities. In this model, the individual may assume the sick role and attempt to incentivize his or her disability. In contrast, the social integrative model views disability as a naturally-occur ring phenomenon. Through full participation in occupa tions and roles, the individual will become more resil ient, therefore regaining health and wellness. 7 Therapists WAR AND REHABILITATION: OCCUPATIONAL THERAPYS POWER TO TRANSFORM DISABILITY INTO ABILITY US Army Medical Command OPORD 15-31 February 2015 Internal military document not readily accessible by the general public.

January March 2016 37 must be cautious in labeling clients as disabled. Instead, care must be taken to assist the Soldier in creating a new identity, one that promotes ability. Finally, as with any system of multilayer administrative and clinical processes, there may be unexpected delays or breakdowns in coordination in regards to delivery of care. In-processing, out-processing, and any executive healthcare system may expose the Soldier to getting lost process of the Integrated Disability Evaluation System, which determines whether a Soldier can return to duty or separate from military service with a disability payment, is recognized as slow-moving. 8 Occupational therapists should strive to educate Soldiers on the functions of the WTU, while simultaneously keeping the Soldier motivat ed, goal-focused, and proactive towards discharge. As sisting Soldiers to take an active role in managing their own care provides accountability and a sense of purpose. Overall, lessons cultivated go far beyond the WTU, and within the civilian sector of support systems. APPLIC A TION WITHIN THE CIVILI A N SECTOR Civilian social supports provide similar opportunities to incentivize disability. With the implementation of the Affordable Care Act in 2010, Medicaid coverage was ex panded, adding millions of individuals to this system of care. 9 Supporters stated the expansion provided assis tance for individuals who, prior to the initiative, did not qualify. However, challengers of this expansion argue that it may promote dependence on the governments as sistance. Social Security Disability Insurance is a highly criticized program which cycles around an individuals impairment(s) and inability to provide for oneself, pos sibly incentivizing disability and encouraging exaggera tion of symptoms. 10 These systems of support are only a few of the civilian programs which are criticized for potential encouragement to remain in the system, ac cepting a dysfunctional disability role as part of ones personal identity. The roots of occupational therapy and history have shown that individuals need meaningful roles and en gagement in occupations to restore or maintain overall health. Occupation has been recognized as a means of treatment for mental and physical illness since the 18th century, long before the term occupational ther 5 In 1915, Hall and Buck 11 discussed the importance of engagement, or occupation in occupational therapy lingo, as a means of recuperation, stating: For the well-to-do, work with the hands may be a potent remedy against the harmful effects of idleness As a profession, occupational therapists have known for nearly a century that participation in occupations is a way to restore health. Whether in the WTU or in the ci vilian sector, occupational therapists do well to remind clients that it is in their best interest to be engaged and fully participate in occupations. Furthermore, in pursuit of health for clients, occupational therapists may simul taneously discourage unnecessary reliance on social support and subsequent idleness. CONCLUSION In any social support system, loopholes will be found and resources may be unjustly over-utilized. As this is never the purpose of these programs, health profession als should transform unhealthy mindsets and behaviors toward independence. As the past has demonstrated, occupational therapy practitioners can be instrumental in analyzing and altering the future of such services. Through war and rehabilitation, Army occupational therapists have the unique opportunity to be actively involved in a large, evolving healthcare system. The WTU is simply one example of a support system devel military or civilian sector, it is the duty of occupational therapists to motivate clients to accomplish the mission of return to function, independence, health, and partici pation in meaningful occupations. In this way the focus is empowerment, not entitlement. REFERENCES 1. Priest D, Hull A. Soldiers face neglect, frustra tion at Armys top medical facility. The Washing ton Post. February 18, 2007.

January March 2016 47 Safety, quality, and the cost of healthcare are currently at the forefront of healthcare discussions in the United States. One of the most vulnerable periods for a hospital ized patient occurs during transfer of that patients care among providers or between healthcare settings. This since these transitions of care are prone to confusion, miscommunication, and medical errors. 1,2 Within hospital systems, discharge planning services aim to ease the patient transition from the hospital. Many studies suggest that these services decrease cost and utilization rates. A 2013 Cochrane review evalu ated the value of hospital discharge planning and deter mined that individualized hospital discharge plans lead to reductions in hospital length of stay and readmission rates. 3 Additional evidence in the Cochrane review was inconsistent regarding the impact of discharge planning on cost, mortality, or other health outcomes. When compared to the availability of hospital-based discharge planning services, fewer systems exist to as sist patients after discharge from the hospital. Often, patients experience problems which arise after their hospital discharge, but prior to a follow-up appointment. During this time, hospital discharge planners are not al ways available, and the patients primary care medical problems that may arise during the transition of care from the hospital include inaccurately reconciled medi cation lists, inadequate access to appropriate social sup port or transportation to appointments, poorly coordi nated postdischarge home medical services, or lack of access to a physician for follow-up outpatient care. Each of these issues can contribute to medical errors, patient morbidity, and rehospitalization rates. 4,5 As these prob lems have become more apparent, they have become in creasingly studied in an attempt to decrease costs while improving patient safety and the quality of care deliv ered during the transition periods. One of the strongest bodies of evidence supporting a deliberate approach to facilitating care transitions is described in Boston Universitys Project RED (ReEngineered Discharge) research group (https://www. Project RED researchers executed and evaluated strategies for successful patient transition from the inpatient to the outpatient care set tings. Through the development and implementation of reduced both hospital readmissions and postdischarge visits to the ED. 6 As an additional part of their project, they published a tool kit for other health teams to employ when discharging patients. 7 Other studies demonstrated Implementation of a Transition of Care Coordinator at a Military Treatment Facility LTC Dana Nguyen, MC, USA CPT Sarah Strickland, MC, USA CPT Blake Busey, MC, USA CPT Ashley Roselle, MC, USA LTC Mark Stackle, MC, USA CPT Scott Hahn, MC, USA Tammy Donoway, DO CPT Nick Bennett, MC, USA ABSTR A CT A patients transition from the inpatient to the outpatient setting is complex and prone to medical errors. This subsequently increases patient morbidity and cost to the healthcare system. Methods: Our quality improvement initiative used a licensed clinical social worker from within a Family Medi cine residency clinic to serve as a Transitions of Care Coordinator (TOCC) with the goal of decreasing patient morbidity and system cost. Results: P =.01). Pearson correlation during our postimplementation period suggested an inverse relationship between contact by a TOCC and emergency department (ED) and hospital utilization rates ( r =-0.68, P =.05 and r =0.062, P =.005, respectively). However, P P cantly increased overall between the pre-and postimplementation periods. Conclusions: increased the frequency of ED visits and readmissions to the inpatient service for patients discharged from the Family Medicine inpatient service.


48 similar evidence with regard to the effect of discharge planning protocols on ED utilization and hospital read mission rates. 8-11 Studies such as these have led to campaigns throughout the United States designed to improve the quality of pa tient care delivered during this transition period. One of the largest such campaigns is the 2010 Partnership for Patients Campaign led by the Department of Health and Human Services. As part of this campaign, over 3,700 hospitals have collaborated in order to make hospitals safer, less costly, and more reliable. One of the 2 corner stone goals of the Partnership for Patients campaign is to 12 The Department of Defense and the Military Healthcare System (MHS) joined other federal agencies to support the Partnership for Patients campaign. 13 As part of its campaign, the MHS recommended adoption of the Project RED toolkit within its healthcare facilities. Based on this MHS recommendation and other local mandates to improve the quality of healthcare within our institution, the leadership of the Womack Army Medical Center established a Project RED team to fa cilitate transitions of care throughout its health system. As part of this effort, the Family Medicine residency clinic implemented the use of a licensed clinical social worker to serve as the transitions of care coordinator (TOCC) for patients enrolled in the residency clinic and cared for by the Family Medicine inpatient team. The TOCCs primary role was to enable effective and safe transitions of care from the inpatient ward to the followup outpatient appointment. With the implementation of the TOCC, our objectives were to increase the number of patients that had follow-up appointments with their primary care manager (PCM) shortly after hospital dis charge, identify and assist with patient problems post hospitalization, decrease the frequency of emergency department (ED) visits posthospitalization, decrease hospital readmissions to the Family Medicine inpatient team, and improve the overall quality of care for our high acuity patients. Overall, we aimed to study the relative quality metrics associated with implementation of a transitions of care coordinator within an academic clinic in the MHS. METHODS This study was conducted as a local quality improve ment initiative. Within our Family Medicine residency clinic at a large Army military treatment facility, we implemented a TOCC to facilitate a smoother transition to outpatient healthcare for patients recently discharged from the hospital. We chose a licensed clinical social worker to assume this role. The initial step in our transition of care protocol was for the TOCC to contact all patients discharged from the Family Medicine inpatient team within 48 hours of discharge. The TOCC used a structured interview script based on Project RED guidelines which reviewed the pa tients diagnosis, discharge medications, follow-up ap pointments, consultations, and overall plan of care. The the patients had a follow-up visit in our clinic (prefera bly with the primary care manager), answering patients questions about their hospitalization, ensuring patients received any indicated postdischarge services, bringing medication reconciliation questions to the attention of the inpatient team and the PCM, and addressing any ad ditional patient concerns. The TOCC conducted these encounters telephonically and documented the results within the electronic medical record. All adult admissions to the Family Medicine inpatient team from February 2013 through March 2014 were evaluated monthly for primary outcomes data. Chart re views were conducted with the following primary out come variables recorded: 1. Number of patients contacted by the TOCC within 48 business hours. 2. Number of patients who completed a follow-up visit within 7 days of discharge in our practice. 3. Number of patients who completed a follow-up visit within 7 days of discharge with their PCM. 4. Number of patients who completed a follow-up visit within 14 days of discharge in our practice. 5. Number of patients who completed a follow-up visit within 14 days of discharge with their PCM. 6. Number of ED visits within 30 days of admission. 7. Number of readmissions to our facility within 30 days of discharge. A run chart was constructed from this data to identify any emerging trends. At 6 months following the TOCC implementation, the data was analyzed by run charts as well as via SPSS Statistics 20.0 (IBM Corp, Armonk, New York) analysis. RESULTS Table 1 shows the demographic characteristics of the pa tient groups admitted to the Family Medicine inpatient adult medicine service during the preimplementation and the postimplementation periods. Outcome variables were assessed comparing the preimplementation and the postimplementation periods for the TOCC. During this analysis, we did not consider whether the TOCC actual ly contacted the patient during the postimplementation IMPLEMENTATION OF A TRANSITION OF CARE COORDINATOR AT A MILITARY TREATMENT FACILITY

Additionally, the percentage of ED vis P =.02) and hospital readmissions P =.01) increased during the postimple mentation period.

Over the course of 6 months, the number of patients from our practice contacted within 48 business hours after hospital dis this time period, the percentage of patients completing a follow-up appointment within 14 days of discharge also increased. This increase also included the num ber of patients that were able to see their PCM. The percentage of ED visits as well as the percentage of patients readmitted within 30 days appeared to have a declining trend after our implementation. No trends of discharge. The postimplementation data was analyzed for correla tions using Pearson product moment correlation. The Table 2. In the post implementation period, receiving a phone call within 48 hours postdischarge from our TOCC correlated inversely with 30-day readmissions, as well as ED visits following hospital discharge ( r = -0.68, P =.05 and r =0.062, P =.005, respectively). The 14-day PCM follow-up visit also correlated, though less strongly, with decreased ED visits and 30-day read missions following discharge ( r =-0.13, P =.017 and r = -0.31, P =.006, respectively). The postimplementation period was also analyzed to determine if an actual contact within 48 hours by the TOCC or within 14 days by the PCM made differences in patient outcomes among this group. Tables 3 and 4 show this data. Contact by the TOCC within 48 hours talization ED utilization or hospital readmission rates. Patient follow-up within 14 days of hospitalization with P admission rates. Finally, data from February and March of 2013 was compared to data from February and March of 2014 to identify possible seasonal variation. In 2014, there was a slight reduction in ED visits following implementation of the TOCC (Figures 2 and 3). Between 2013 and 2014, ED visits in February and March, respectively. Between 2013 and 2014, there was an absolute rate increase of 2014 for 30 day hospital readmissions, respectively.

50 review of the overall preimplementation and postimple mentation data suggests that our populations ED visits and readmissions actually increased after our TOCC initiative. Similarly, when considering the possible ben we theorized that higher rates of PCM visits would de crease utilization rates. This was not the case, however, as patients seeing their PCM within 14 days during our utilization and hospital readmission rates. The cause of these seemingly paradoxical results is unclear. Patients typically have increased morbidity rates in the posthospitalization period. Increased con tact by our outpatient practice may be simply identify ing problems or complications at an earlier time period. Although this may negatively affect utilization rates, it may be providing improved quality of care in regard to long-term patient outcomes. This was not evaluated in our study. Also, examining data from across our entire medical center would generate stronger statistical power to assess the increased utilization rates. In our postimplementation period, higher rates of timely contact by the TOCC was inversely correlated with the ED and hospital utilization rates, as evaluated by a Pear 2 analysis of these measures rates of utilization for those same patients.

January March 2016 51 tion of our practice patients being contacted within 48 contacted with 48 hours of discharge was not met due to transfers to other facilities, deaths, and a myriad of administrative challenges. Timely patient contact was hampered by incorrect phone numbers, patients who did not return phone calls, and the lack of an alternate TOCC when the primary TOCC was on vacation or ill. Despite these limitations, most discharge were contacted by our practice within a week. The use of a licensed clinical social worker as our TOCC is unique since most facilities use nurses for this func tion. The potential drawbacks of using a social worker in the role include unfamiliarity with the medications reviewed as part of the 48-hour telephone encounter. To cine reconciliation issue, he relayed the concern to both the discharging inpatient team as well as to the PCM. The advantages of using a social worker as a TOCC in clude an understanding of how to navigate a complex medical system, experience in the coordination of out patient specialty referrals and appointments, and an ap in this role include professional training and experience with counseling patients and clear communication and emotional support. There are several limitations to our study. We did not consider variables other than those described above. During the period that the TOCC was established, addi tional changes within our health system occurred which inpatient team standardized the written discharge sum mary and instructions given to all patients. Additionally, the ED transitioned from a paper health record to an electronic medical record. Each of these changes may have independently affected our studys outcomes or the ability to capture data accurately. The standardized dis charge summary was part of an overall quality improve ment measure for the Family Medicine inpatient team and was designed in accordance with Project RED and Medicare documentation requirements with their em phasis on improved readability. Additionally, we only studied patients within our military medical system. Our practice patients who were admitted to hospitals other than our facility were not included in the analysis. Despite the unanticipated outcomes involving ED utili zation and hospital readmission rates after our interven tion, the strategies used by our team within this quality improvement initiative subjectively enhanced commu nication and coordination of care within our practice. studys objectives, a standardized script for the TOCC, a standardized discharge summary format for the Family Medicine inpatient team, and the establishment of com mon, obtainable goals. We believe that the value we de rived from these strategies can be replicated, and should be used throughout the MHS. CONCLUSION The implementation of a TOCC within an academic tient populations frequency of ED visits and hospital re admissions after discharge. However, trends during our postimplementation period suggest possible future ben The broader medical literature still largely supports an ing transitions in care. Therefore, the MHS should in vestigate the utility of this effort on a larger scale. REFERENCES 1. Forster AJ, Murff HJ, Peterson JF, Gandhi TK, Bates DW.

January March 2016 71 Although 90% of American adults now own a mobile phone and 64% own some form of smartphone, 1,2 the opportunities for using them in healthcare delivery have remained largely unexplored. Mobile phones are porta ble, accessible, and ideal for transmitting individualized information; thus, they have the potential to provide means to streamline healthcare at relatively small cost outlays. 3 For now, however, applying mobile phone use to that found in academic studies; despite the evidence indicating the prospective value of employing mobile technology in healthcare, we found no indication that federal healthcare leaders have exercised the capacity on a scale of any magnitude. We recognize the substantial potential for using mobile phones in the areas of primary, preventive, and population health, and a need for federal healthcare to improve its use of this technology to stay competitive in the areas of access, costs, and satisfaction. To seize that potential and answer that need, we propose a 5-year federal implementation plan to integrate mobile phone capabilities into federal healthcare delivery. METHODS We began our analysis with a comprehensive review of the literature. Using Google Scholar, the Association for Computing Machinery Database, and PubMed, we queried the extant recent literature (2009 to the present) using the following criteria: mobile phone health appli cations and cell phone text message health From the result of our query, we included articles and studies spe healthcare. We excluded those articles that did not have a focus on the use of mobile phones toward improving healthcare such as articles concerning the medical side effects of prolonged cell phone use. From our review and analysis of the initial set of articles, in mobile application use in healthcare: primary, preven tive, and population health applications. These themes include search query terms such as mobile phones pri mary care and cell phone preventive health Synthesiz articles for subsequent analysis. Our review of the stud ies formed our recommendation. FINDINGS Primary Care for the patient. 4 Mobile Phone Health Applications for the Federal Sector Capt Christin S. Burrows, MS, USAF MAJ Fred K. Weigel, MS, USA ABSTR A CT Purpose: role in the future of healthcare delivery. Today, 90% of American adults own a mobile phone and 64% own a smartphone, yet many healthcare organizations are only beginning to explore the opportunities in which mo bile phones can improve and streamline care. Method: After searching Google Scholar, the Association for Computing Machinery Database, and PubMed for articles related to mobile phone health applications and cell phone text message health, we selected articles review and analysis. Findings: healthcare: primary, preventive, and population health. We recommend federal health leaders pursue the value and potential in these areas; not only because 90% of Americans already own mobile phones, but also because mobile phone integration can provide substantial access and potential cost savings. Conclusion: propose a 5-year federal implementation plan to integrate mobile phone capabilities into federal healthcare delivery. Our proposal has the potential to improve access, reduce costs, and increase patient satisfaction, there fore changing the way the federal sector delivers healthcare by 2021.


72 mobile phone technology in healthcare delivery is found in primary care. Both the civilian and federal sectors face a primary care shortage, and the lack of access cre ates overcrowded emergency rooms and rising costs. 4 In the United States, primary care access is one of health cares biggest challenges, 5 and recent studies show that various mobile phone applications can help to improve that access. First, messaging capabilities between primary care managers and patients can reduce the number of routine visits that do not require face-to-face interaction, such as for prescription renewals. Military treatment facility administrators have started to explore secure messaging in primary care delivery. Secure messaging provides a method to communicate health information electroni cally while protecting the health information from un authorized viewing. Available on mobile phones, a goal of secure messaging is to ease communication between primary care managers and patients, allowing patients to ask routine questions without an appointment. Imple mented correctly, the secure messaging system can im prove access for those who need a physical visit, recap turing care that the military might otherwise send to the civilian sector. Second, studies show that using text messaging for ap pointments, resulting in up to 40% improved attendance rates. 6,7 These attendance rates receive great attention and are highly visible in the federal system, because of the negative effect that missed appointments have on ac cess and costs. Most efforts to improve missed appoint ment rates in the military are based on enforcing pu nitive measures, but these recent studies suggest that a proactive text messaging approach can be very effective and a viable alternative. 6,7 Although the US Army has started to use text messages as appointment reminders, the method has been employed only on a limited scale. 8 Finally, mobile phones have the potential to improve ac cess by enabling providers and disease managers to ef fectively monitor chronic conditions. Most relevant stud ies focus on diabetes, hypertension, and asthma man agement. 9 Many studies show that text messaging and proving blood sugar measures in diabetes patients who received continual text messages to monitor and con trol their levels. 9 These encouraging text messages spur patients to be involved with their own care, which can help keep them from further complications. Therefore, effective disease management via mobile phones pro vides a viable option to preserve valuable primary care appointment availability through inspiring a high level of patient engagement in personal health maintenance. Preventive Health and immunization reminders, among others. Research ers often focus on smoking cessation, in part because smoking is so prevalentit is the leading cause of pre mature deaths in the United States and responsible for 1 in 5 deaths nationwide 10 and because mobile phone intervention results are so dramatic, increasing cessa tion rates by up to 70%. 11 Most experiments include interactive text messages that send smokers positive to messages when the smokers need extra encourage ment. These studies have been among those indicating the most effective mobile phone use interventions; the tion rates both in the shortand long-term. 11,12 However, there is limited published literature about mobile phone use as a smoking cessation tool, and that lack of litera ture may be a contributing factor to Whittaker and col providing a long-term effect on smoking cessation. 11 Another potential preventive health application is the use time interventions. 13 People could program their phone workplace smoking area and favorite fast food restaurant A visit to these loca tions would generate a reminder to avoid unhealthy be haviors, intervening in moments of weakened willpower. The main goal for any preventive health intervention is to change poor behaviors while encouraging good be haviors, so incentives have a large role in mobile phone integration with preventive care. Most mobile phone prevention studies to date focus on intrinsic rewards ward a goal. 14,15 However, there may be an opportunity to study prevention with other reward systems, especial ly in the social networking setting. Ultimately, preven tion, with or without mobile phones, is about positively responsibility for healthcare. Population Health Mobile phones have several applications in popula tion health. Healthcare leaders could adopt the model of other data-gathering industries and collect individ ual health information via mobile phones, analyzing MOBILE PHONE HEALTH APPLICATIONS FOR THE FEDERAL SECTOR


January March 2016 73 the data to determine current and localized trends in population health. There are already applications test amounts of user-input data to determine where out breaks happen. 16 For example, Chunara and colleagues 16 outline their own Outbreaks Near Me, an application for Android and iPhone smartphones, with which users can provide real-time disease outbreak reports. They further describe other applications for disease and disaster re porting as well as the ability to integrate the reporting with internet-based outbreak monitoring systems, such as ( These types of applications are especially helpful with primary care managers when they have a virus that only requires symptom management, so the primary care facility may not have an accurate picture of the virus prevalence without self-reporting. Once trends materi alize, mobile phones can be used to disseminate popu lation health messages back to the people. Patients can their area and provide helpful reminders such as to wash their hands or get vaccinated. This infrastructure would be particularly helpful for population protection; if pub messaging could disseminate that information to many people simultaneously. Although the Army has started to explore mobile phone 8 many federal administrators have not been quick to adopt mobile phone technology, perhaps due to the asso ciated challenges. We propose the implementation of a 5-year plan that depends on the federal sectors ability to Integrated into our proposal, federal health leaders will have to implement security measures to protect patient information as well as decide how to best capture vir tual workload and collect reimbursement from insurers. Without good reimbursement methods, detailed costsavings of mobile phone use is almost impossible. We provide greater detail of our proposal in the next section. CO MM ENT After researching effective methods for incorporat ing mobile phones into health delivery, we propose a 3-phase, 5-year plan for the federal sector to improve access, costs, and patient satisfaction by 2021, allowing federal health to compete in todays health environment. perfecting the new secure messaging systems in mili tary health. For example, the Air Force is currently introducing its secure messaging system, MiCare, which advertises a 72-hour response time from a primary care managers. 17 It is critical that Air Force leadership focuses cordingly; if this response window is broken early and often in MiCares debut, patients will view secure mes saging as a burden instead of an improvement to their health delivery, making them very hesitant to participate in future efforts. Secure messaging is a pilot program for the federal sector, and military treatment facility leaders should take great care to ensure a smooth implementation. The second phase in our proposal, lasting approximately 2 years, includes implementing high-visibility programs of interactive appointment and smoking cessation re minders. First, federal health will focus on interactive appointment messages, giving patients the option to reply and immediately reschedule. This is a relatively simple way to improve access and gain patient support for future mobile phone integration. Second, the federal sector will implement an interactive messaging system to assist with smoking cessation in its health and well ness centers. Encouraging smokers to quit is important for both individual health and rising healthcare costs, and this effort will again garner further support for fu ture mobile health applications. Gaining the patients for the third phase. mobile phones into the federal health sectors disease management and population health programs. This phase depends on the success of patient engagement mobile phones receives the appropriate public support response, federal health providers can next start col lecting information from the patients. Patients can input disease management measures into applications or text messages, which can give the provider better oversight and identify complications before they become severe. Potentially, the disease management information could be integrated into currently available internet-based out break monitoring platforms. Similarly, public health of to analyze localized illness trends. LI M IT A TIONS A ND ADDITION A L RESE A RCH As with other approaches that focus on the archival anal ysis, the sampling procedure is a limitation. 18 Despite search criteria for this study, the potential search criteria options are vast. It is possible, perhaps likely, that had we included additional search terms, our search would


74 have revealed additional articles that would inform this study. Likewise, had we searched in additional databas es, we may have unearthed other literature. Future re scope and database selections. Through this research, we exposed several areas for fur ther inquiry. Although there are numerous studies on appointment reminders, most that we found are limited to one-way messaging: caregivers to patients. Future studies should consider investigating interactive mes saging with rescheduling capability, as well as its effect on access. We found that the literature on cost-savings for mobile phones in healthcare is also lacking. Explor ing reimbursement models for provider messaging and the effect on costs would contribute insights into reduc ing costs in healthcare mobile phone use that would be of interest to both researchers and practitioners. An additional limitation for this study is the sheer pace of innovation; because technology changes at a rapid pace, arguably, some of our suggested applications for mobile phone use may be obsolete and supplanted by newer technology by 2021. Future researchers should note that because of the pace of technology innovation and development, the 5-year plan we propose is suitable for longitudinal study. CONCLUSION The federal health system should employ the 5-year inte gration plan now to fully use mobile phones in the areas of primary, preventive, and population health. Employ ing these programs quickly and accurately can help the federal healthcare sector stay competitive in todays en vironment by improving access, controlling purchasedcare costs, and increasing patient satisfaction, all of which will change the way that federal administrators deliver healthcare as we head into the 2020s.

76 Care of prisoners or inmates of correctional facilities poses unique challenges. These include considerations of security threats, challenge of transportation under secure conditions, a varying and highly transient popu lation, and often the remote locations of correctional fa cilities must all be taken into account when developing a strategy for medical care of this population. In Europe, the US Army Correctional Facility (COR FAC) was previously located at Mannheim, Germany, 45 geographical miles from the nearest military medi cal treatment facility (MTF). It moved in 2015 and is now located in Sembach, Germany. The location is 30 to 60 minutes from provider locations at various clin ics. The CORFAC census generally ranges from 13-15 inmates who are young (aged 18-40 years) and generally to a stateside correctional facility. This mission requires cient use of a full time privileged medical provider. Ad ditionally, the requirement for a provider to commute to and from the CORFAC daily put an unacceptable burden on the productivity of that providers assigned clinic. Therefore, a solution was proposed in the form of establishing a telehealth protocol. Telehealth, the practice of interviewing and examining a patient from a remote location using the assistance of trained technicians and high quality video and sound equipment, has been studied for many years in various settings, including prison facilities. 1-5 While TH has have been inconsistent. 6 One concept that seems to be clear is that despite initial resistance from providers and patients, the effectiveness, and satisfaction (for both pro viders and patients) tends to increase with time and ex posure to TH medicine. 1,7,8 The Department of Defense and Landstuhl Regional Medical Center (LRMC) have invested in the expansion and development of a TH program which has potential in communities that are not large enough to justify a dedicated provider. A Primary Care Telehealth Experience in a US Army Correctional Facility in Germany LTC Christian Swift, AN, USA Steven M. Cain, MPAS, PA-C CPT Michael Needham, MC, USA ABSTR A CT Objective: To assess the feasibility of using telehealth (TH) equipment and infrastructure within the US Armys European Theater to evaluate and treat inmates with general medical complaints, and perform physicals and medical safety checks in a US Army Correctional Facility (CORFAC). Methods and Materials: Synchronous TH encounters were performed using Polycom RealPresence software Practitioner Cart along with AMD Global Telemedicine devices at the originating site within the CORFAC. These devices included an AMD-2500 General Exam Camera, AMD Fiber optic Otoscope, and AMD Telephonic Stethoscope. Patient consent for TH was obtained, and they were seen in the Medical Dispensary with Army Medics presenting the patients to the providers via TH. Results: From May 22, 2014, to January 12, 2015, a physician assistant, nurse practitioner, and 4 physicians completed 177 synchronous TH encounters primarily at a CORFAC in Mannheim, Germany. Of these 177 encounters, 114 were Special Housing Unit (SHU) safety checks and 63 encounters were for physicals, medication management, and a variety of medical complaints including acute infections, abdominal pain, and musculoskeletal and dermatological complaints. Conclusion: Synchronous TH was an effective option for the delivery of high quality routine medical care for minor illnesses, injuries, and other nonurgent conditions, as well as for general physicals and SHU checks in a correctional facility. Acceptance by providers and clinic staff was found to be high. Inmates were generally highlighting one of the challenges with acceptance of telehealth programs.


January March 2016 77 This article reviews the implementation ropean CORFAC. The support of this type of unit can be accomplished by any TH trained provider from any location where video conferencing equipment was available. Any provider connected to the Europe Regional Medical Com mand (ERMC) intranet can perform medical video teleconferencing from was to assess the feasibility of medical visits via TH while meeting the medi cal mission needs of the CORFAC. The result envisioned was high quality care while decreasing the time and costs spent in provider transportation to and from his/her assigned location. MA TERI A LS A ND METHODS Program Organization Implementation of this TH effort re quired a rethinking of the delivery of medical care at the CORFAC by the dispensary technician staff, the pri mary care providers, and ultimately the patients themselves. Initially, potential sistance from medical personnel, lack culties coordinating services. In March (THPO) and the CORFAC Dispensary Team began meeting to work through barriers and technical and clinical is sues. A standard operating procedure was written with guidelines outlining tasks and roles. Inquiries were made to the American Correctional Association regarding the feasibility and legality of TH in prison systems. Many institutions in the United States were using some form of TH, even if only simple telephonic connections. A 2004 survey of institutions in all 50 states revealed that slightly over eral institutions use some type of TH or telemedicine applications. 1 Armed with some existing experience de livering specialty care via synchronous TH in Europe, THPO began training providers and dispensary medical technicians in the use of TH equipment. Per Army Tele health Policy Memo 08-053,* written informed consent is required prior to participating in synchronous TH. This is obtained from inmates during CORFAC initial processing. Only one inmate chose not to consent to being seen for his medi cal issues via TH. Telehealth Clinic was performed Monday through Friday, ex cept Wednesdays when a provider was present at the CORFAC. Inmates would register for sick call the night prior and at an agreed upon time the next morn ing, the TH Clinic would commence in which both patient and the provider would meet in the Virtual Exam Room. The medics assisted providers with physical exam elements during the TH encounter. Special Housing Unit checks were also performed via TH during weekdays. The Special Housing Unit (SHU) is a location within the correctional facil ity where inmates are in cells in what Special Housing Unit checks are a daily medical safety check which must be performed by a credentialed medical provider assessing both the inmates cell condition and the general health of the inmate. Special Housing Unit checks consist of a brief presentation by the guard staff as to the condition of the cell and a brief interview with the inmate regarding any overnight health issues or concerns. A review of Ameri can Correctional Association Guide checks via TH met the duty of the facil ity to provide face-to-face credentialed provider daily medical safety checks. 2 A small group of internists at LRMC were trained to perform these checks via TH on weekends. Sick call presenting complaints were mostly minor in volving medication issues, acute illnesses, and injuries as shown in the Table. Physical exams were performed via TH using mostly the TH general exam camera, stethoscope, and otoscope. Emergency procedures were in place for the occasion that an inmate presents to the TH sick call with a problem requiring evaluation at the Emergency Department.

78 Fiberoptic Otoscope, and AMD Telephonic Stethoscope (AMD Global Telemedicine, Chelmsford MA) (Figures 1, 2). By 2010, nearly all Army clinics in Europe had ro bust TH capabilities. Although not originally slated for the equipment, these items were installed at the COR FAC from a clinic in Germany which was not using them were installed in all behavioral health clinics including tioner Cart and the telehealth general exam camera, oto to perform comprehensive assessments of patients at the CORFAC for most primary care/sick call complaints presented by this patient group. Telehealth Equipment at Distant Site Technicians from the LRMC Video Network Center (VNC) installed PolyCom RealPresence software on providers laptops at Kleber Army Health Clinic and installed on monitors on the provider desks or in a video teleconference (VTC) room. LRMC Video Network Center The LRMC VNC manages the VTC servers for both nonmedical and medical conferencing using PolyCom CMA Gatekeeper. At the initiation of every medical VTC encounter, the VNC technicians would assign the connection for patient privacy. The VNC also checked the audio and video quality of each encounter and were available anytime there were connection problems. Rarely were there any audio/video issues and there were no technical issues that prompted cessation of TH ser vices. Bandwidth within the ERMC Network was suf near negligible network delay. Electronic Medical Record Data and Peer Review Encounters and provider notes were documented in the patients outpatient military electronic medical record (AHLTA). Physician peer review was performed and no Data Patient encounter data for physicals and sick call visits were culled from a variety of sources, including a pass word-protected ERMC TH cart reservation calendar for which all TH Encounters in ERMC are documented, and daily printed AHLTA clinic lists from the CORE FAC dispensary. Special Housing Unit checks were all documented on a CORFAC blotter report and each in an electronic Standard Form 600 signed by the provider assigned that day. RESULTS Providers participating in the care of inmates via TH consisted of a physician assistant, nurse practitioner, family practitioner, and a group of 3 internists who saw inmates on the weekend for SHU checks.

January March 2016 79 providers completed 177 synchronous TH encounters, primarily at the Mannheim and Sembach CORFACs. Patients were seen weekly from May 22, 2014, to Janu ary 12, 2015. Of these 177 TH encounters, 114 were SHU safety checks and 63 were for physicals, medication vis its, and a variety of other typical acute care complaints. During this time, only one patient required transfer to a higher level of care during a TH encounter. The inmate complained of severe epigastric pain which necessitated transfer to the LRMC Emergency Department for evalu ation due to the limitation of ancillary services of lab and x-ray at the US Army Correctional Facility-Europe. Primary Care Encounters The routine physical and sick call types of encounters comprised 63 of the encounters as shown in the Table. About one-third (24) of those encounters were for physi cals and medication visits. All newly incarcerated in mates require an initial medical screening to assess any 48 hours of arrival. Intake medical screenings and phys icals were accomplished using synchronous TH equip ment. The remainder of the encounters addressed a vari ety of complaints which were easily assessed using TH. Special Housing Unit Checks The SHU encounters consisted of a brief presentation by the CORFAC medic or guard staff relaying the ap pearance and condition of the inmates cell and any overnight events affecting the inmates health. The en counters were brief and did not require use of telehealth examination devices. The encounters were very easily accomplished via TH. A SHU check could turn into a medical encounter if the inmate had a medical com plaint, but this did not occur during the pilot study. Provider, Staff and Inmate Satisfaction Although not formally surveyed, there was a generally good acceptance by the providers involved in the pro gram and appreciation for the high quality of the net work connections and TH medical devices used. The clear advantage for providers was being able to man age minor sick-call type complaints and physicals via driving. There was general acceptance of the idea of stered knowing that every Wednesday a provider would be in-house to see inmates and perform follow-ups. There was also recognition that contingency plans and access to local emergency service was also available if required. Providers noted satisfaction with the capabili ties of the TH equipment to include general exam cam with the telephonic stethoscope. It seemed to perform well for heart sounds when the distant provider wore headphones. For breath sounds however, it seemed less useful, possibly due to cord or connection interference noise. The idea of seeing patients from a distance via TH is new to many medical care providers and although acceptance is not immediate, providers recognize that high quality encounters can be achieved and acceptance improves over time. ence. Many inmates did express a preference to see a many of the initial intake medical screenings of the in mates are performed while the patients are handcuffed. Despite some reported dissatisfaction, nearly all inmates freely consented to the encounters and many came back multiple times for TH services, even though they could have waited to be seen in person on Wednesdays. Gen erally, medical visits via TH seemed to meet inmate ex pectations for high quality health care. CO MM ENT The Landstuhl THPO and CORFAC partnership started in March 2014 and has developed into an enduring line of service which continues to assist in the performance checks using synchronous TH. There is somewhat of a learning curve in both performing TH encounters as a provider and receiving care via TH as a patient. It is the view of the authors that not all types of care can be suc cessfully accomplished via TH. This particular group of inmates in this smaller correctional facility represented for short periods. However, in a larger institution with a more diverse inmate population, carefully consid ered screening criteria should be incorporated into de veloping TH programs. That is particularly important for screening to determine which patients may require a carefully nuanced or specialized physical exam or may have more urgent or emergent conditions that re quire treatment. Telehealth encounters may be used as a screening tool; an information-gathering encounter to assess whether a patient may need a face-to-face en counter or higher level of care facility. Telehealth may also be used for medical education classes such as dia betes education. CONCLUSIONS Synchronous TH was shown to be a feasible and ef fective option for the delivery of high quality, routine medical care for minor illnesses, injuries, and other nonurgent and nonemergent conditions, as well as for general physicals and checks in a population aged 18 to 30 years. Synchronous TH provided a platform for


80 safe and effective health care delivery to this popula tion over a 7month period. Overall, the TH encounters appeared to be accepted by providers and clinic staff. A conservative estimate is that 660 hours of unproduc tive provider time traveling to and from the facility was encounters. Some inmates did report a preference to see providers in person. This highlights one of the challeng es with TH programs and their acceptance by both pro viders and patients. The authors believe that acceptance should improve over time as with most new technologi cal advances.

January March 2016 81 Repair of a Gingival Fenestration Using an Acellular Dermal Matrix Allograft COL Lawrence G. Breault, DC, USA CPT Raquel C. Brentson, DC, USA COL Edward B. Fowler, DC, USA COL Frederick C. Bisch, DC, USA ABSTR A CT A case report illustrating the successful treatment of a gingival fenestration with an acellular dermal matrix (ADM) allograft. After 2 months of healing, the ADM was completely integrated into the soft tissues of the mandibular anterior gingiva with complete resolution of the gingival fenestration, resulting in excellent gingi val esthetics. Marginal tissue recession is of 2 types; one due to peri odontitis and the other primarily related to mechanical factors like tooth brushing. Recession from periodonti tis can involve all tooth surfaces, while recession from mechanical factors typically involves only one surface. Periodontitis is associated with plaque and calculus whereas facial recession is associated with high levels of personal oral hygiene and professional care. Predis posing factors to gingival recession include frenal pull, underlying bone dehiscence, subgingival restorations, tooth malposition, orthodontic appliances, and thin gin gival biotype. 1-5 While a wide array of various gingival defects may be diagnosed in patients, only those anomalies that also present with associated symptoms, esthetic concerns, or the potential for exacerbated sequelae may require treatment. Two commonly discussed localized gingival defects include the gingival dehiscence and fenestration. The more common of the two, the gingival dehiscence, is de scribed as an isolated area in which the root is denuded of bone. 6 The defect combines 3 characteristic qualities including gingival recession, bone loss through the mar gin of the bone, and root exposure (Figure 1). 7 In contrast, the gingival fenestration is a rarer phenom enon. 1,7,8 The word fenestration is derived from the Latin word fenestra, meaning window, which describes how the defect clinically presents. 7 A fenestration may be distinguished by the loss of overlying alveolar bone and gingiva, which results in an exposed root surface, but the marginal bone and gingiva remain intact (Figure 2). 7 Gingival fenestration defects are of uncertain etiolo gy. 1,2,7 Some authors have suggested the etiology of gin gival fenestration as subgingival calculus and the use of Gutka (a mixture of powdered tobacco, areca nut [fruit of Arecacatechu ] and slaked lime [aqueous calcium hy droxide]). 1 Other reports of gingival fenestrations have listed etiologies as extreme buccal inclination of root tips with thin or nonexistent cortical plates combined 9,10 Additionally, two of the authors (LGB and EBF) have clinically attrib uted gingival fenestrations to possible trauma leading to Figure 1 Gingival dehiscence. Figure 2 Gingival fenestration.


82 bony sequestration (Figure 2) and to past use of smoke less tobacco with subsequent healing over previously exposed root calculus. Localized gingival defects are routinely corrected with autogenous grafts from either the palatal mucosa or buc cal gingiva. However, many patients may not desire a palatal graft due to the additional morbidity of the pro bleeding from the palatal donor site. 4,11 The surgical correction of gingival defects have evolved from the early use of pedicle grafts originally described by Grupe and Warren in 1956. 12 Presently, with the ad vent of the autogenous subepithelial connective tissue graft (SCTG), as described by Langer and Langer with creased to more than 90%. 13-17 An alternative to the autogenous graft is the acellular dermal matrix (ADM ) allograft. The material is human dermis which has been decellularized and treated to prevent disease transmission, leaving only a scaffold of Type I collagen. 18 of the morbidity associated with graft removal from an oral site. Several authors have reported on the success of ADM allograft 4,18-21 Repair of gingival fenestrations has been reported in the literature. 1,22-25 Previous case reports all used the SCTG for repair of the defects. This article reports a case of repair of a gingival fenestration using an ADM allograft. CA SE REPORT A male, 28-year-old Soldier was referred to the Depart ment of Periodontics for evaluation of his mandibular anterior gingiva associated with tooth #24, a mandibular central incisor (Figure 3). The patient reported a history of daily smokeless tobacco use in the area of the man dibular anterior but reported complete cessation of this product approximately 2 years prior. Subsequent to the cessation of smokeless tobacco use, the patient noticed an irregularity of his gingiva, which upon clinical examination was determined to be a gin gival fenestration (Figure 3). A review of the medical history revealed that the patient was taking no medications and no contraindications to treatment were noted. All surgical options were pre sented and discussed. The patient selected ADM as the material for the procedure. Following a presurgical rinse with 0.12% chlorhexidine and administration of local anesthesia (2% lidocaine with 1:100,000 epinephrine), the gingival fenestration was excised to expose new connective tissue margins REPAIR OF A GINGIVAL FENESTRATION USING AN ACELLULAR DERMAL MATRIX ALLOGRAFT Perio Derm: Dentsply International, Inc; York, PA.

January March 2016 83 (Figure 4). The labial tissue was elevated to create a pouch. The tissue preparation was intentionally de signed to avoid the marginal gingiva, thereby decreas ing the chance of postsurgical recession. Following the removal of calculus with ultrasonic instrumentation, root planing was completed with hand instruments. The ADM was hydrated according to the manufacturers instructions (Figure 5), and placed under the elevated labial tissue as shown in Figure 6. The allograft was se cured with 5.0 Chromic Sutures* (Figure 7). The labial tissue was then closed over the ADM using 5.0 Vicryl Sutures* (Figure 8). Hemostasis was obtained with di rect pressure for 2 minutes. Home instruction included daily chlorhexidine oral rinsing every 12 hours as well as the administration of pain medications: acetamino phen (500 mg) with codeine (30 mg) (1 to 2 tabs every 4 to 6 hours as needed for severe pain and naproxen (500 mg) (1 tab every 12 hours as needed for moderate pain). The patient was followed at one, 2, 4, and 10 weeks (2 the soft tissues with complete integration of the ADM allograft (Figure 9). CO MM ENT Although gingival fenestration is a relatively rare occur rence, as this case report demonstrates, one of the etiolo gies of this condition can be resolution of a smokeless tobacco lesion over previously exposed calculus. The predictable repair of this clinical entity has been earlier demonstrated with the autogenous subgingival connec tive tissue graft. 1,22-25 This report demonstrates the success of surgical treat ment utilizing ADM. The advantage of this technique is the elimination of the need for autogenous donor tis sue. Additionally, the surgical design in this case did not incorporate the free gingival margin, thus reducing the risk of postsurgical recession or dehiscence formation.

Moderate Risk Criteria (any of the following) One or two incipient or cavitated primary or secondary carious lesions during current exam. No incipient or cavitated primary or secondary carious lesions during current exam but presence of at least one factor that may increase caries risk. High Risk Criteria (any of the following) Three or more incipient or cavitated primary or secondary carious lesions diagnosed during current exam. Presence of multiple factors that may increase caries risk. Xerostomia (medication, radiation, or disease induced). Suboptimal fluoride exposure (inadequate/no systemic fluoride, inadequate topical fluoride exposure). Poor oral hygiene. Irregular dental visits. Incipient lesions are noncavitated localized or generalized white spots and/or interproximal radiolu cencies. Risk Factors: factors that increase the risk of developing caries include, but are not limited to: Deep pits and fissures. Many multisurface restorations. Exposed root surfaces. Eating disorders. Frequent sugar intake (>5 times per day). Restoration overhangs and open margins. Active orthodontic treatment. Chemotherapy or radiation therapy. Developmental or acquired enamel defects. Physical disability that impedes oral hygiene. Inadequate salivary flow, as determined from PMH or unstimulated salivary flow testing (<0.2 mL/min). Source: American Dental Association
