Health Care Utilization During the First 5½ Years of Authorized Service by Transgender U.S. Service Members (2016-2021).

Purpose: This study examined the utilization of gender-affirming health care by active-duty service members during the initial 5½ years that transgender and gender-diverse (TGD) individuals were authorized to serve in the U.S. military. The aim of this study was to inform policy discussions regarding inclusion of TGD individuals in the military. Methods: We conducted a retrospective cohort study using administrative health care data from the Military Data Repository (MDR). We assessed the association of demographic factors with the utilization of gender-affirming medical and surgical care. We calculated the incidence rate of initial TGD-related encounters and new prescriptions for gender-affirming hormones among Defense Department Service members between July 2016 and December 2021. Results: We identified 2481 service members with an initial health care encounter with an associated TGD-related diagnosis. More than half (53%) of these service members started gender-affirming hormones, and 14% underwent gender-affirming surgery. Mastectomies and hysterectomies accounted for more than 70% of surgeries. Service members made 3.22 initial encounters with a TGD-related diagnosis per 10,000 service members per year, with an overrepresentation of service members who were designated female in the MDR (8.62), junior enlisted (4.98), and young (4.64). Individuals designated female in the MDR comprised 17% of all service members but accounted for 46% of initial encounters, 51% of new prescriptions, and 73% of surgeries. Conclusion: The study revealed a higher-than-expected number of service members seeking gender-affirming care, particularly among service members designated female in the MDR. Military Health System clinicians provided most of this care, which may mitigate the cost of delivering this essential medical care.

Variation in Time-to-Gender-Affirming Hormone Therapy in the US Active Duty Service Members.

BACKGROUND: Beginning in July 2016, transgender service members in the US military were allowed to receive gender-affirming medical care, if so desired. OBJECTIVE: This study aimed to evaluate variation in time-to-hormone therapy initiation in active duty Service members after the receipt of a diagnosis indicative of gender dysphoria in the Military Health System. RESEARCH DESIGN: This retrospective cohort study included data from those enrolled in TRICARE Prime between July 2016 and December 2021 and extracted from the Military Health System Data Repository. PARTICIPANTS: A population-based sample of US Service members who had an encounter with a relevant International Classification of Diseases 9/10 diagnosis code. MEASURES: Time-to-gender-affirming hormone initiation after diagnosis receipt. RESULTS: A total of 2439 Service members were included (Mage 24 y; 62% white, 16% Black; 12% Latine; 65% Junior Enlisted; 37% Army, 29% Navy, 25% Air Force, 7% Marine Corps; 46% first recorded administrative assigned gender marker female). Overall, 41% and 52% initiated gender-affirming hormone therapy within 1 and 3 years of diagnosis, respectively. In the generalized additive model, time-to-gender-affirming hormone initiation was longer for Service members with a first administrative assigned gender marker of male relative to female (P<0.001), and Asian and Pacific Islander (P=0.02) and Black (P=0.047) relative to white Service members. In time-varying interactions, junior enlisted members had longer time-to-initiation, relative to senior enlisted members and junior officers, until about 2-years postinitial diagnosis. CONCLUSION: The significant variation and documented inequities indicate that institutional data-driven policy modifications are needed to ensure timely access for those desiring care.

Incidence and prevalence of eating disorders among active duty US military-dependent youth from 2016 to 2021.

OBJECTIVE: The offspring of US military service members may be at increased risk for eating disorders. However, no epidemiological studies to date have evaluated eating disorder incidence rates and prevalence estimates among military-dependent youth. METHOD: This retrospective cohort study examined eating disorder diagnoses in the military healthcare system (MHS) from 2016 through 2021. Active duty and national guard military-dependent youth, aged 10-17 years, who received care in the MHS via TRICARE Prime insurance, were identified by one or more ICD-10 codes indicative of an eating disorder diagnosis (anorexia nervosa, bulimia nervosa, binge-eating disorder, and other-specified eating disorders). RESULTS: During the 6-year surveillance period, 2534 dependents received incident diagnoses of eating disorders, with a crude overall incidence rate of 1.75 cases per 10,000 person-years. The most common diagnosis was other-specified eating disorder, followed by anorexia nervosa, bulimia nervosa, and binge-eating disorder. The crude annual incidence rate of all eating disorder diagnoses increased by nearly 65% from 2016 to 2021. Rates for all diagnoses were highest in 2020 and 2021. Period prevalence estimates were .08% for any eating disorder diagnosis, .01% for anorexia nervosa, .004% for bulimia nervosa, .004% for binge-eating disorder, and .06% for other-specified eating disorders. DISCUSSION: The observed increase in eating disorder diagnoses during the surveillance period appeared to be driven by female dependents. More military dependents experienced a new-onset diagnosis during the COVID-19 pandemic compared to previous years. These findings highlight the need for eating disorder screening, identification, and treatment for dependents within the MHS. PUBLIC SIGNIFICANCE STATEMENT: Children of US military service members may be at increased risk for eating disorders. Results indicate new-onset eating disorder cases increased 65% from 2016 to 2021, primarily among girls compared to boys. The most diagnosed and fastest growing diagnosis was other-specified eating disorder. Rates of anorexia nervosa increased following the COVID-19 pandemic. Findings highlight the need for eating disorder screening, identification, and treatment within the military healthcare system.

Assessing the postdeployment quality of treatment for substance use disorders among Army enlisted soldiers in the Military Health System.

Little is known about the rates and predictors of substance use treatment received in the Military Health System among Army soldiers diagnosed with a postdeployment substance use disorder (SUD). We used data from the Substance Use and Psychological Injury Combat study to determine the proportion of active duty (n = 338,708) and National Guard/Reserve (n = 178,801) enlisted soldiers returning from an Afghanistan/Iraq deployment in fiscal years 2008 to 2011 who had an SUD diagnosis in the first 150 days postdeployment. Among soldiers diagnosed with an SUD, we examined the rates and predictors of substance use treatment initiation and engagement according to the Healthcare Effectiveness Data and Information Set criteria. In the first 150 days postdeployment 3.3% of active duty soldiers and 1.0% of National Guard/Reserve soldiers were diagnosed with an SUD. Active duty soldiers were more likely to initiate and engage in substance use treatment than National Guard/Reserve soldiers, yet overall, engagement rates were low (25.0% and 15.7%, respectively). Soldiers were more likely to engage in treatment if they received their index diagnosis in a specialty behavioral health setting. Efforts to improve substance use treatment in the Military Health System should include initiatives to more accurately identify soldiers with undiagnosed SUD. Suggestions to improve substance use treatment engagement in the Military Health System will be discussed.

A Tale of Two Databases: The DoD and VA Infrastructure for Clinical Intelligence (DaVINCI).

The Department of Defense (DoD) and Department of Veterans Affairs (VA) Infrastructure for Clinical Intelligence (DaVINCI) creates an electronic network between the two United States federal agencies that provides a consolidated view of electronic medical record data for both service members and Veterans. This inter-agency collaboration has created new opportunities for supporting transitions in clinical care, reporting to Congress, and longitudinal research.

Pre-deployment Year Mental Health Diagnoses and Treatment in Deployed Army Women.

We estimated the prevalence of select mental health diagnoses (MHDX) and mental health treatment (MHT), and identified characteristics associated with MHT during the pre-deployment year (365 days before deployment) in active duty Army women (N = 14,633) who returned from Iraq or Afghanistan deployments in FY2010. Pre-deployment year prevalence estimates were: 26.2 % for any select MHDX and 18.1 % for any MHT. Army women who had physical injuries since FY2002 or any behavioral health treatment between FY2002 and the pre-deployment year had increased odds of pre-deployment year MHT. During the pre-deployment year, a substantial percentage of Army women had MHDX and at least one MHT encounter or stay. Future research should determine if pre-deployment MHDX among Army women reflect vulnerability to future MHDX, or if pre-deployment MHT results in protection from chronic symptoms.

Rationale and methods of the Substance Use and Psychological Injury Combat Study (SUPIC): a longitudinal study of Army service members returning from deployment in FY2008-2011.

The Substance Use and Psychological Injury Combat Study (SUPIC) will examine whether early detection and intervention for post-deployment problems among Army Active Duty and National Guard/Reservists returning from Iraq or Afghanistan are associated with improved long-term substance use and psychological outcomes. This paper describes the rationale and significance of SUPIC, and presents demographic and deployment characteristics of the study sample (N = 643,205), and self-reported alcohol use and health problems from the subsample with matched post-deployment health assessments (N = 487,600). This longitudinal study aims to provide new insight into the long-term post-deployment outcomes of Army members by combining service member data from the Military Health System and Veterans Health Administration.
