RESUMO
There is a paucity of evidence connecting health literacy, perceived wellness, self-reported fitness activity, or military readiness to wearable devices. Moreover, we do not currently know the prevalence and impact of health tracker device use in the active-duty Air Force population. This prospective cross-sectional survey assessed self-reported fitness activity, health-related quality of life, health literacy, and health behavior tracking practices and preferences among active-duty Air Force service members. Four hundred twenty-eight respondents completed an online survey, with 247 selecting tracking a health behavior and 181 selecting that they did not track a health behavior. Demographic characteristics of the sample showed no significant differences in age, sex distribution, or mode of service. We found that there were no significant differences in self-reported aerobic and strength training frequency, health literacy, or health-related quality of life. More than half of nontracking respondents either had not considered or had no interest in tracking health behaviors. Nearly three-quarters of tracking respondents tracked more than one health behavior. Further research could explore the extent to which these technologies improve fitness, health outcomes, and overall readiness in the military, involving longitudinal studies tracking fitness improvements and health outcomes among service members using wearable devices.

BACKGROUND/PURPOSE: Meeting recommendations that nurses should partner in leading health care change is hampered by the lack of ambulatory care nurse-sensitive indicators (ACNSIs). This scoping review was conducted to identify evidence regarding ACNSI identification, development, implementation, and benchmarking. METHODS: Following the PRISMA-ScR reporting guide, we performed PubMed/MEDLINE, CINAHL, and Cochrane Library searches for the period January 2006 to March 2021. RESULTS: Twelve of the 1984 articles from 6 countries met inclusion criteria. All focused on identifying, developing/pilot testing indicators, and included structure, process, and outcome indicators. Seven articles were level II and all were at least grade B quality. Leverage points involved leadership support, automated data extraction infrastructure, and validating links between nurses' roles/actions and patient outcomes. CONCLUSIONS: While high-quality work is ongoing to identify clinically meaningful and feasible ACNSIs, knowledge in this field remains underdeveloped. Prioritizing this work is imperative to address gaps and facilitate national strategic health care goals.

Psychiatric aeromedical evacuations are one of the leading causes of medical related evacuations of US military personnel from combat. Currently, no studies have examined gender and marital status of individuals who were evacuated from combat for a psychiatric diagnosis. Psychiatric aeromedical evacuation data from 5,957 United States military personnel deployed to Iraq or Afghanistan between 2001 and 2013 were analyzed using chi-square tests of independence, odds ratios (OR), and standardized residuals. Analyses showed that female service members were evacuated at higher rates (178 per 100,000) than males (115 per 100,000). When compared to nonmarried females, married females did not present with increased risk of psychiatric aeromedical evacuation on any diagnosis. Married males, however, were more likely to be evacuated than married females for PTSD (OR = 1.98) and TBI (OR = 1.14). Likewise, married males, compared to nonmarried males, were more likely to be evacuated for PTSD (OR = 1.66) and anxiety (OR = 1.38). Although deployments can be extremely stressful experiences for some military service members, they may be especially so among unmarried females and married males. This study provides a unique contribution to enhancing the understanding of risk factors related to psychiatric aeromedical evacuation for deployed service members.
RESUMO
PURPOSE: With few trained genetics professionals, the Military Health System is ill-equipped to manage the rapid expansion of genomic medicine. The MilSeq Project introduces an alternative service delivery model (ASDM) in which primary health-care providers (HCPs) provide post-test counseling (PTC) to healthy Airmen who have undergone exome sequencing. We describe HCP performance after a prerequisite educational intervention (EI). METHODS: After a brief EI and pre-/posteducation surveys, HCPs were eligible to provide PTC with a genetic counselor available for consult. PTC was recorded, transcribed, and reviewed. Opportunities for improvement were organized into four error adjustment categories: (1) knowledge limitation, (2) minor, (3) moderate, and (4) critical. Thematic analysis was also performed. RESULTS: Pre-/posteducation survey responses revealed statistically significant improvements in all domains. Minor error adjustments were most represented (n = 93), followed by knowledge limitation (n = 39) and moderate (n = 19). No critical errors were identified, and 17 transcripts required no adjustment. Thematic analysis revealed four themes that would benefit from more focused education: (1) family-centered care, (2) conveying risk, (3) disease knowledge, and (4) assay knowledge. CONCLUSION: HCPs demonstrated competence in basic PTC after a brief EI. This ASDM may be a viable interim response to the shortage of genetics professionals in some systems.

PURPOSE: The use of genomic sequencing (GS) in military settings poses unique considerations, including the potential for GS to impact service members' careers. The MilSeq Project investigated the use of GS in clinical care of active duty Airmen in the United States Air Force (USAF). METHODS: We assessed perceived risks, benefits, and attitudes toward use of GS in the USAF among patient participants (n = 93) and health-care provider participants (HCPs) (n = 12) prior to receiving or disclosing GS results. RESULTS: Participants agreed that there are health benefits associated with GS (90% patients, 75% HCPs), though more HCPs (75%) than patients (40%) agreed that there are risks (p = 0.048). The majority of both groups (67% HCPs, 77% patients) agreed that they trust the USAF with genetic information, but far fewer agreed that genetic information should be used to make decisions about deployment (5% patients, 17% HCPs) or duty assignments (3% patients, 17% HCPs). Despite their hesitancy, patients were supportive of the USAF testing for nondisease traits that could impact their duty performance. Eighty-seven percent of patients did not think their GS results would influence their career. CONCLUSION: Results suggest favorable attitudes toward the use of GS in the USAF when not used for deployment or assignment decisions.

BACKGROUND: Genotyping has expanded the number red blood cell (RBC) and platelet (PLT) antigens that can readily be typed, but often represents an additional testing cost. The analysis of existing genomic data offers a cost-effective approach. We recently developed automated software (bloodTyper) for determination of RBC and PLT antigens from whole genome sequencing. Here we extend the algorithm to whole exome sequencing (WES). STUDY DESIGN AND METHODS: Whole exome sequencing was performed on samples from 75 individuals. WES-based bloodTyper RBC and PLT typing was compared to conventional polymerase chain reaction (PCR) RHD zygosity testing and serologic and single-nucleotide polymorphism (SNP) typing for 38 RBC antigens in 12 systems (17 serologic and 35 SNPs) and 22 PLT antigens (22 SNPs). Samples from the first 20 individuals were used to modify bloodTyper to interpret WES followed by blinded typing of 55 samples. RESULTS: Over the first 20 samples, discordances were noted for C, M, and N antigens, which were due to WES-specific biases. After modification, bloodTyper was 100% accurate on blinded evaluation of the last 55 samples and outperformed both serologic (99.67% accurate) and SNP typing (99.97% accurate) reflected by two Fyb and one N serologic typing errors and one undetected SNP encoding a Jknull phenotype. RHD zygosity testing by bloodTyper was 100% concordant with a combination of hybrid Rhesus box PCR and PCR-restriction fragment length polymorphism for all samples. CONCLUSION: The automated bloodTyper software was modified for WES biases to allow for accurate RBC and PLT antigen typing. Such analysis could become a routing part of future WES efforts.

BACKGROUND: The inability of patients to accurately and completely recount their clinical status between clinic visits reduces the clinician's ability to properly manage their patients. One way to improve this situation is to collect objective patient information while the patients are at home and display the collected multi-day clinical information in parallel on a single screen, highlighting threshold violations for each channel, and allowing the viewer to drill down to any analog signal on the same screen, while maintaining the overall physiological context of the patient. All this would be accomplished in a way that was easy for the clinician to view and use. METHODS: Patients used five mobile devices to collect six heart failure-related clinical variables: body weight, systolic and diastolic blood pressure, pulse rate, blood oxygen saturation, physical activity, and subjective input. Fourteen clinicians practicing in a heart failure clinic rated the display using the System Usability Scale that, for acceptability, had an expected mean of 68 (SD, 12.5). In addition, we calculated the Intraclass Correlation Coefficient of the clinician responses using a two-way, mixed effects model, ICC (3,1). RESULTS: We developed a single-screen temporal hierarchical display (VISION) that summarizes the patient's home monitoring activities between clinic visits. The overall System Usability Scale score was 92 (95% CI, 87-97), p < 0.0001; the ICC was 0.89 (CI, 0.79-0.97), p < 0.0001. CONCLUSION: Clinicians consistently found VISION to be highly usable. To our knowledge, this is the first single-screen, parallel variable, temporal hierarchical display of both continuous and discrete information acquired by patients at home between clinic visits that presents clinically significant information at the point of care in a manner that is usable by clinicians.

INTRODUCTION: Every year, approximately 35,000 recruits enter the United States Air Force Basic Military Training (BMT). Musculoskeletal problems are particularly vexing for BMT because a broad array of differentials render definitive diagnosis burdensome and while most sufferers will fully recover, healing often requires protracted training delays resulting in increased unrecoverable training costs to the program. The purpose of this study is to conduct a case-control study of basic military trainees entering service from 2012 to 2015 to assess detectable differences in demographics, retention, and health care utilization. MATERIALS AND METHODS: This is a retrospective case-control study of existing data and records obtained from existing and active information record systems for individuals who attended BMT between the years 2012 and 2015. Cohort assignment was based on incidence of first stress fracture diagnosis (i.e., having a select diagnosis code in one's medical record) relative to arrival at BMT. Health care utilization is operationalized as medical encounter frequencies and associated international classification of disease (ICD) codes occurring for all patients from BMT recruit date of arrival to 6 months post-graduation (i.e., 180 days). RESULTS: The primary dataset includes 132,359 distinct individuals, of which 129,637 (98%) had no history of stress fracture diagnosis and 1,487 (1%) of which have a diagnosis of stress fracture more than 60 days after arrival at BMT; these are assigned to the CONTROL group. There are 1,235 (0.9%) assigned to the CASE group. CASE members presented with 30.1 unique ICD-10 codes post-graduation compared to 6.3 in the CONTROL group. Six of the top thirteen ICD-10 codes were musculoskeletal in nature and all presented significantly higher rates for the CASE group. CONCLUSIONS: Trainees who suffered a bone stress injury (BSI) during the United States Air Force BMT advanced in rank on par with trainees who did not, but BSI sufferers exhibited greater health care utilization than those who did not suffer BSI. The cost to replace a trainee unable to complete BMT is considerable; however, it is also important to consider the reduction in resiliency and readiness to the Department of Defense and the financial burdens from increased health care utilization. The 2-fold increase in BSI presentation in the graduated control group reflects that more needs to be done for all populations to identify better proactive efforts to foundationally support wellness and prevention rather than accept injury as the status quo.

Using healthy adult participants, seven measures of heart rate variability were obtained simultaneously from four devices in five behavioral conditions. Two devices were ECG-based and two utilized photoplethysmography. The 140 numerical values (measure, condition, device) are presented. The comparative operational reliability of the four devices was assessed, and it was found that the two ECG-base devices were more reliable than the photoplethysmographic devices. The interchangeability of devices was assessed by determining the between-device Limits of Agreement. Intraclass correlation coefficients were determined and used to calculate the standard error of measurement and the Minimal Detectable Difference. The Minimal Detectable Difference, MDD, quantifies the smallest statistically significant change in a measure and is therefore critical when HRV measures are used longitudinally to assess treatment response or disease progression.
RESUMO
INTRODUCTION: Within the Military Health System, the process of transporting patients from an initial point of injury and throughout the entire continuum of care is called "en route care." A Committee on En Route Combat Casualty Care was established in 2016 as part of the DoD Joint Trauma System to create practice guidelines, recommend training standards, and identify research priorities within the military en route care system. MATERIALS AND METHODS: Following an analysis of currently funded research, future capabilities, and findings from a comprehensive scoping study, members of a sub-working group for research identified the top research priorities that were needed to better guide evidence-based decisions for practice and policy, as well as the future state of en route care. RESULTS: Based on the input from the entire committee, 10 en route care research topics were rank-ordered in the following manner: (1) medical documentation, (2) clinical decision support, (3) patient monitoring, (4) transport physiology, (5) transfer of care, (6) maintaining normothermia, (7) transport timing following damage control resuscitation or surgery, (8) intelligent tasking, (9) commander's risk assessment, and (10) unmanned transport. Specific research questions and technological development needs were further developed by committee members in an effort to guide future research and development initiatives that can directly support operational en route care needs. The research priorities reflect three common themes, which include efforts to enhance or increase care provider capability and capacity; understand the impact of transportation on patient physiology; and increase the ability to coordinate, communicate, and facilitate patient movement. Technology needs for en route care must support interoperability of medical information, equipment, and supplies across the global military health system in addition to adjusting to a dynamic transport environment with the smallest possible weight, space, and power requirements. CONCLUSIONS: To ensure an evidence-based approach to future military conflicts and other medical challenges, focused research and technological development to address these 10 en route care research gaps are urgently needed.

The STRONG STAR Consortium (South Texas Research Organizational Network Guiding Studies on Trauma and Resilience) and the Consortium to Alleviate PTSD are interdisciplinary and multi-institutional research consortia focused on the detection, diagnosis, prevention, and treatment of combat-related posttraumatic stress disorder (PTSD) and comorbid conditions in military personnel and veterans. This manuscript outlines the consortia's state-of-the-science collaborative research model and how this can be used as a roadmap for future trauma-related research. STRONG STAR was initially funded for 5 years in 2008 by the U.S. Department of Defense's (DoD) Psychological Health and Traumatic Brain Injury Research Program. Since the initial funding of STRONG STAR, almost 50 additional peer-reviewed STRONG STAR-affiliated projects have been funded through the DoD, the U.S. Department of Veterans Affairs (VA), the National Institutes of Health, and private organizations. In 2013, STRONG STAR investigators partnered with the VA's National Center for PTSD and were selected for joint DoD/VA funding to establish the Consortium to Alleviate PTSD. STRONG STAR and the Consortium to Alleviate PTSD have assembled a critical mass of investigators and institutions with the synergy required to make major scientific and public health advances in the prevention and treatment of combat PTSD and related conditions. This manuscript provides an overview of the establishment of these two research consortia, including their history, vision, mission, goals, and accomplishments. Comprehensive tables provide descriptions of over 70 projects supported by the consortia. Examples are provided of collaborations among over 50 worldwide academic research institutions and over 150 investigators.

INTRODUCTION: Suicide is a significant problem in the U.S. military, with rates surpassing the U.S. general population as of 2008. Although there have been significant advances regarding suicide risk factors among U.S. military service members and veterans, there is little research about risk factors associated with suicide that could be potentially identified in theater. One salient study group consists of service members who receive a psychiatric aeromedical evacuation out of theater. The primary aims of this study were as follows: (1) determine the incidence of suicide-related aeromedical evacuation in deployed service members, (2) identify demographic and military characteristics associated with suicide-related aeromedical evacuation, and (3) evaluate the relationship between suicide-related aeromedical evacuation from a deployed setting and military separation. MATERIALS AND METHODS: This was an archival analysis of U.S. Transportation Command Regulating and Command and Control Evacuation System and Defense Manpower Data Center electronic records of U.S. military service members (N = 7023) who were deployed to Iraq or Afghanistan and received a psychiatric aeromedical evacuation out of theater between 2001 and 2013. χ2 tests of independence and standardized residuals were used to identify cells with observed frequencies and proportions, respectively, that significantly differed from what would be expected by chance. In addition, odds ratios were calculated to provide context about the nature of any significant relationships. RESULTS: For every 1000 psychiatric aeromedical evacuations that occurred between 2001 and 2013, 34.4 were suicide related. Gender, ethnicity, branch of service, occupation classification, and deployment theater were associated with suicide-related aeromedical evacuation (odds ratios ranged from 1.37 to 3.02). Overall, 53% of all service members who received an aeromedical evacuation for any psychiatric condition had been separated from the military for a variety of reasons (both voluntary and involuntary) upon record review in 2015. Suicide-related aeromedical evacuation was associated with a 37% increased risk of military separation compared to evacuation for another psychiatric condition (P < 0.02). CONCLUSIONS: Findings provide novel information on risk factors associated with suicide-related aeromedical evacuation as well as military separation following a suicide-related aeromedical evacuation. In many cases, the psychiatric aeromedical evacuation of a service member for suicidal ideations and their subsequent separation from active duty is in the best interest of the individual and the military. However, the evacuation and eventual military separation can be costly for the military and the service member. Consequently, the military should focus on indicated prevention interventions for individuals who show sufficient early signs of crisis and functional problems so that specialized interventions can be used in theater to prevent evacuation. Indicated prevention interventions should start with leaders' awareness and mitigation of risk and, when feasible, evidence-based interventions for suicide risk provided by behavioral health (eg, brief cognitive behavioral therapy for suicide). Future research should evaluate the feasibility, safety, and efficacy of delivering suicide-related interventions in theater.

Introduction: Use of electronic secure messaging (SM) is rapidly growing in various healthcare settings. However, there is a large number of patients that choose not use SM or use it minimally. Thus, understanding preferences for patient-provider communication modalities is critically important, particularly among military healthcare beneficiaries. The purpose of this study was to assess preferences for patient-provider communication modalities (in person, telephone, SM, or mail) among a sample of patients, providers, and staff located at five Air Force military treatment facilities across the USA. Methods: We recruited patients, providers, and staff, from five family health clinics to complete a short survey. We measured participants' preferences for communication modality for various healthcare concerns, such as responses to non-urgent medical questions, test results, and medication renewal information. We also measured satisfaction with MiCare, the Air Force's SM system. We conducted chi-square analyses and Fisher's exact tests to assess differences in communication preferences by patients, providers, and staff and we computed frequencies in satisfaction responses. Results: We found that while providers and staff (N = 70) prefer to communicate with patients about various healthcare concerns online through MiCare, patients (N = 1,260) prefer to communicate in-person or through the telephone. Patients were generally satisfied with MiCare; however, there was a large proportion of patients who were undecided about MiCare's impact on the quality of care they received (40.3%). Additionally, although the majority of providers and staff believed MiCare improved their efficiency (58.0%) and communication with patients (72.3%), 65.7% of providers and staff believed MiCare had increased their workload. Conclusion: MiCare is a promising tool to improve patient-provider communication. However, future studies are needed to better understand why patients within the military healthcare system prefer communication modalities other than MiCare and to identify strategies to decrease provider and staff workloads while using MiCare.

Introduction: The primary objective of this study was to describe the demographic, clinical, and attrition characteristics of active duty U.S. military service members who were aeromedically evacuated from Iraq and Afghanistan theaters with a psychiatric condition as the primary diagnosis. The study links the U.S. Transportation Command Regulating and Command and Control Evacuation System (TRAC2ES) data with the Defense Manpower Data Center (DMDC) to conduct an examination of the long-term occupational impact of psychiatric aeromedical evacuations on military separations and discharges. Materials and Methods: Retrospective analyses were conducted on the demographic, clinical, and attrition information of active duty service members (N = 7,023) who received a psychiatric aeromedical evacuation from Iraq or Afghanistan between 2001 and 2013 using TRAC2ES data. Additionally, TRAC2ES database was compared with DMDC data to analyze personal and service demographics, aeromedical evacuation information, and reasons for military separation with the entire 2013 active duty force. Chi-square tests of independence and standardized residuals were used to identify cells with observed frequencies or proportions significantly different than expected by chance. Additionally, OR were calculated to provide context about the nature of any significant relationships. Results: Compared with the active duty comparison sample, those with a psychiatric aeromedical evacuation tended to be younger, female, white, divorced or widowed, and less educated. They were also more likely to be junior enlisted service members in the Army serving in a Combat Arms military occupational specialty. The primary psychiatric conditions related to the aeromedical evacuation were depressive disorders (25%), adjustment disorders (18%), post-traumatic stress disorder (9%), bipolar disorders (6%), and anxiety disorders (6%). Approximately, 3% were evacuated for suicidal ideation and associated behaviors. Individuals who received a psychiatric aeromedical evacuation were almost four times as likely (53%) to have been subsequently separated from active duty at the time of the data analysis compared with other active duty service members (14%). The current study also found that peaks in the number of aeromedical evacuations coincided with significant combat operational events. These peaks almost always preceded or followed a significant operational event. An unexpected finding of the present study was that movement classification code was not predictive of subsequent reasons for separation from the military. Thus, the degree of clinical supervision and restraint of a service member during psychiatric aeromedical evacuation from deployment proved to be unrelated to subsequent service outcome. Conclusions: Psychiatric conditions are one of the leading reasons for the aeromedical evacuation of active duty military personnel from the military combat theater. For many active duty military personnel, a psychiatric aeromedical evacuation from a combat theater is the start of a military career-ending event that results in separation from active duty. This finding has important clinical and operational implications for the evaluation and treatment of psychiatric conditions during military deployments. Whenever possible, deployed military behavioral health providers should attempt to treat psychiatric patients in theater to help them remain in theater to complete their operational deployments. Improved understanding of the factors related to psychiatric aeromedical evacuations will provide important clinical and policy implications for future conflicts.

BACKGROUND: The current approach to the outpatient management of heart failure involves patients recollecting what has happened to them since their last clinic visit. But patients' recollection of their symptoms may not be sufficiently accurate to optimally manage their disease. Most of what is known about heart failure is related to patients' diurnal symptoms and activities. Some mobile electronic technologies can operate continuously to collect data from the time patients go to bed until they get up in the morning. We were therefore interested to evaluate if patients would use a system of selected patient-facing devices to collect physiologic and subjective state data in and around the patients' period of sleep, and if there were differences in device use and perceptions of usability at the device level METHODS: This descriptive observational study of home-dwelling patients with heart failure, between 21 and 90 years of age, enrolled in an outpatient heart failure clinic was conducted between December 2014 and June 2015. Patients received five devices, namely, body weight scale, blood pressure device, an iPad-based subjective states assessment, pulse oximeter, and actigraph, to collect their physiologic (body weight, blood pressure, heart rate, blood oxygen saturation, and physical activity) and subjective state data (symptoms and subjective states) at home for the next six consecutive nights. Use was defined as the ratio of observed use over expected use, where 1.0 is observed equals expected. Usability was determined by the overall System Usability Scale score. RESULTS: Participants were 39 clinical heart failure patients, mean age 68.1 (SD, 12.3), 72% male, 62% African American. The ratio of observed over expected use for the body weight scale, blood pressure device, iPad application, pulse oximeter and actigraph was 0.8, 1.0, 1.1, 0.9, and 1.9, respectively. The mean overall System Usability Scale score for each device were 84.5, 89.7, 85.7, 87.6, and 85.2, respectively. CONCLUSIONS: Patients were able to use all of the devices and they rated the usability of all the devices higher than expected. Our study provides support for at-home patient-collected physiologic and subjective state data. To our knowledge, this is the first study to assess the use and usability of electronic objective and subjective data collection devices in heart failure patients' homes overnight.
