Analysis of Telehealth Equity Within the Military Health System During the COVID-19 Pandemic.

Background: Telehealth care expanded during the COVID-19 pandemic, although previous studies show racial, gender, and socioeconomic inequalities in its usage. Racial disparities are known to be mitigated in the Military Health System (MHS), whose 9.6 million beneficiaries are universally insured and nationally representative. This study investigated whether known disparities in telehealth usage were mitigated in the MHS. Methods: This study performed a retrospective cross-sectional study of TRICARE telehealth claims data from January 2020 to December 2021. Beneficiaries aged 0 to 64 years were identified with Common Procedural Terminology code modifiers 95, GT, and GQ, which indicated procedures that were delivered through either synchronous or asynchronous telecommunication services. Visits were defined as one encounter per patient per day. Analyses included descriptive statistics of patient demographics, number of telehealth visits, and differences between military-provided and private sector care (PSC). Military rank was used as a proxy for socioeconomic status (SES), generally combining income, education, and occupation type. Results: A total of 917,922 beneficiaries received telehealth visits during the study period: 25% in direct care, 80% in PSC, and 4% in both care settings. The majority of visits were received by females (57%) and associated with a Senior Enlisted rank (66%). The visits by racial category were proportional to the percentage of each category in the population. The lowest number of visits was for those older than 60 years, potentially receiving Medicare instead, and those associated with Junior Enlisted rank, a potential disparity that may also reflect access to leave or smaller family size. Conclusions and Relevance: Within the MHS, telehealth visits were equitable by race, in line with previous findings, but not by gender, SES, or age. Findings by gender are reflected in the greater U.S. population. Further research is needed to assess and address potential disparities associated with Junior Enlisted rank as proxy for low SES.

Changes in body mass index and behavioral health among adolescents in military families during the COVID-19 pandemic: a retrospective cohort study.

BACKGROUND: Widely published findings from the COVID-19 pandemic show adverse effects on body mass index (BMI) and behavioral health in both adults and children, due to factors such as illness, job loss, and limited opportunity for physical and social activity. This study investigated whether these adverse effects were mitigated in adolescents from military families, who are universally insured with consistent access to healthcare, and who generally have at least one parent who must adhere to physical and mental fitness as a condition of employment. METHODS: We conducted a cohort study using two groups of adolescents receiving care in the U.S. Military Health System during the COVID-19 pandemic; one for changes in Body Mass Index (BMI) and the second for changes in behavioral health diagnoses, using TRICARE claims data. Beneficiaries (160,037) ages 13 to 15 years in fiscal years 2017-2018, were followed up during October 2020 to June 2021. RESULTS: Among the BMI cohort, 44.32% of underweight adolescents moved to healthy weight, 28.48% from overweight to obese, and 3.7% from healthy weight to underweight. Prevalence of behavioral disorders showed an overall 29.01% percent increase during the study period, which included in mood (86.75%) and anxiety (86.49%) disorders, suicide ideation (42.69%), and suicide attempts (77.23%). Decreases in percent change were observed in conduct disorders (-15.93%) and ADD/ADHD (-8.61%). CONCLUSIONS: Adolescents in military families experienced adverse health outcomes during the pandemic at approximately the same rates as those in non-military families, suggesting that universal insurance and military culture were not significantly mitigating factors. Obesity and underweight present significant opportunities to intervene in areas such as exercise and food access. Decreased conduct disorders and ADD/ADHD may reflect lower prevalence due to favorable home environment, or lower rates of diagnosis and referral; however, increased rates of anxiety, mood disorders, suicide ideation and attempt are especially concerning. Care should be taken to ensure that adolescents receive consistent opportunity for physical activity and social interaction, and those at risk for suicide should receive active monitoring and appropriate referral to behavioral healthcare providers.

A cohort study of BMI changes among U.S. Army soldiers during the COVID-19 Pandemic.

BACKGROUND: The increasing number of individuals with obesity is a healthcare concern in the United States (U.S.) population; the men and women who serve in the Army are no exception, with 17.3% of soldiers categorized with a body mass index (BMI) of Obesity in 2017. The COVID-19 pandemic profoundly disrupted life around the globe. During the pandemic, restrictions to soldier movement and activity were put in place to limit COVID-19 transmission. We strive to assess what effects these changes may have had on the BMIs of soldiers. METHODS: We conducted a retrospective cohort study of active duty U.S. Army soldiers using data from the Military Health System Data Repository. BMI was calculated and categorized before (February 2019 - January 2020) and during the pandemic (September 2020 - June 2021). Women who were pregnant or delivered during and one year prior to the study periods were excluded. Statistical analyses included paired t-tests evaluating mean BMI, percent change, and the Stuart-Maxwell test for marginal homogeneity. RESULTS: 191,894 soldiers were included in the cohort. During the pandemic, 50.5% of soldiers in the cohort were classified as Overweight and 23.2% were classified as Obesity. T-test and Stuart-Maxwell test indicated significant differences and changes in BMI categories between the pre-pandemic and pandemic periods, particularly the Obesity category, which experienced a 5% growth and 27% change. Significant absolute changes were observed during the pandemic; 26.7% of soldiers classified as Healthy weight in the pre-pandemic period shifted to Overweight in the pandemic period and 15.6% shifted from Overweight in the pre-pandemic period to Obesity in the pandemic period. Absolute increases were observed across every demographic category in soldiers with obesity; the categories that saw the highest increases were female, ages 20-24, White, and Junior Enlisted soldiers. CONCLUSIONS: Higher rates of obesity may result in decreased health of the force. The specific needs of younger and Junior Enlisted soldiers need to be further addressed, with focus on special intervention programs by the U.S. Army.

A health systems assessment of genetic counseling in cardiovascular care in a large health system: Adherence to genetics recommendations in the Military Health System.

Genetic counseling and genetic testing are important tools for diagnosis, screening, and employment of effective medical management strategies for hereditary cardiovascular diseases. Despite widespread recognition of the benefits of genetic counseling and testing in cardiovascular care, little is published regarding their use in large healthcare systems. We conducted a retrospective cross-sectional study using administrative claims data in the US Military Health System to assess the state of recommended genomic counseling in clinical cardiovascular care. Logistic regression models were used to examine associations of genetic counseling among beneficiaries with hereditary cardiovascular conditions. Approximately 0.44% of beneficiaries in fiscal year 2018 had a diagnosis of a hereditary cardiovascular condition. Among the 23,364 patients with a diagnosis of hereditary cardiovascular disease, only 175 (0.75%) had documented genetic counseling and 196 (0.84%) had documented genetic testing. Genetic counseling did not differ by race, sex, service, or diagnosis. Age group, Active Duty status, rank as a proxy for socioeconomic status, and geographic location contributed significantly to the likelihood of receiving genetic counseling. These findings suggest that genetic counseling is underutilized in clinical cardiovascular care in the Military Health System and may be more broadly, despite expert consensus recommendations for its use and potential life-saving benefits. Unlike previous studies in the US civilian health sector, there did not appear to be disparities in genetic counseling by race or sex in the Military Health System. Strategies to improve care for cardiovascular disease should address the underutilization of recommended genetics evaluations for heritable diagnoses and the challenges of assessing use in large health systems studies.

Postpartum Opioid Use among Military Health System Beneficiaries.

OBJECTIVE: The aim of the study is to evaluate the prevalence and factors associated with opioid prescriptions to postpartum patients among TRICARE beneficiaries receiving care in the civilian health care system versus a military health care facility. STUDY DESIGN: We evaluated postpartum opioid prescriptions filled at discharge among patients insured by TRICARE Prime/Prime Plus using the Military Health System Data Repository between fiscal years 2010 to 2015. We included women aged 15 to 49 years old and excluded abortive pregnancy outcomes and incomplete datasets. The primary outcome investigated mode of delivery and demographics for those filling an opioid prescription. Secondary outcomes compared prevalence of filled opioid prescription at discharge for postpartum patients within civilian care and military care. RESULTS: Of a total of 508,258 postpartum beneficiaries, those in civilian health care were more likely to fill a discharge opioid prescription compared with those in military health care (OR 3.9, 95% CI 3.8-3.99). Cesarean deliveries occurred less frequently in military care (26%) compared with civilian care (30%), and forceps deliveries occurred more frequently in military care (1.38%) compared with civilian care (0.75%). Women identified as Asian race were least likely to fill an opioid prescription postpartum (OR 0.79, 95% CI 0.75-0.83). Women aged 15 to 19 years had a lower odds of filling an opioid prescription (OR 0.83, 95% CI 0.80-0.86). Women associated with a senior officer rank were less likely to fill an opioid prescription postpartum (OR 0.83, 95% CI 0.73-0.91), while those associated with warrant officer rank were more likely to fill an opioid prescription (OR 1.14, 95% CI 1.06-1.23). CONCLUSION: Our data indicates that women who received care in civilian facilities were more likely to fill an opioid prescription at discharge when compared with military facilities. Factors such as race and age were associated with opioid prescription at discharge. This study highlights areas for improvement for potential further studies. KEY POINTS: · Opioid prescription patterns for postpartum women may vary across the country.. · Our study indicates postpartum patients in civilian care are more likely to fill opioids postpartum.. · This study highlights a population which may have an improved opioid prescribing pattern..

Analysis of Telehealth Usage and Trends in the Military Health System, 2006-2018.

Background: Telehealth in the Military Health System (MHS) has long been an important tool for delivering care in deployed settings. However, the scope of nondeployed telehealth usage in the MHS has not previously been published, making full evaluation difficult. This study aims at addressing this gap by assessing trends over time, demographics, provider types, and diagnoses most associated with telehealth usage in the MHS. Methods: Secondary analysis was conducted on health care claims from the MHS Data Repository for all telehealth services provided from fiscal years 2006 to 2018. Telehealth services were identified by using Common Procedural Terminology (CPT) code modifiers GT, GQ, and 95. Patient demographics, provider type, and major diagnostic category were assessed for all telehealth services in both direct (military provided) and purchased (private sector) care. Results: Usage of telehealth services in the MHS rose ∼19-fold, from 2,549 to 48,667 occurrences, from 2006 to 2018. Physicians provided ∼60% of telehealth services overall, and the greatest usage was for mental health diagnoses. Purchased care (PC) showed differences from direct care (DC), including a greater level of expansion, greater inclusion of children and adolescents, and lower usage of telehealth for non-mental health services. Conclusions: Telehealth usage in the MHS has increased substantially from a total 2,549 occurrences in 2006 to 48,667 occurrences in 2018, demonstrating greater acceptance and usage by both DC and PC providers. Future directions include assessing provider types, diagnosis codes, and patient demographics associated with telehealth use, especially in the emerging COVID19 clinical practice environment.

Non-clinical Drivers of Variation in Preoperative MRI Utilization for Breast Cancer.

BACKGROUND: Preoperative magnetic resonance imaging (MRI) utilization in breast cancer treatment has increased significantly over the past 2 decades, but its use continues to have interprovider variability and disputed clinical indications. OBJECTIVE: The aim of this study was to evaluate non-clinical factors associated with preoperative breast MRI utilization. METHODS: This study utilized TRICARE claims data from 2006 to 2015. TRICARE provides health benefits for active duty service members, retirees, and their dependents at both military (direct care with salaried physicians) and civilian (purchased care under fee-for-service structure) facilities. We studied patients aged 25-64 years with a breast cancer diagnosis who had undergone mammogram/ultrasound (MMG/US) alone or with subsequent breast MRI prior to surgery. Facility characteristics included urban-rural location according to the National Center for Health Statistics classification. Adjusted multivariable logistic regression tests were used to identify independent factors associated with preoperative breast MRI utilization. RESULTS: Of the 25,392 identified patients, 64.7% (n = 16,428) received preoperative MMG/US alone, while 35.3% (n = 8964) underwent additional MRI. Younger age, Charlson Comorbidity Index score ≥ 2, active duty or retired beneficiary category, officer rank (surrogate for socioeconomic status), Air Force service branch, metropolitan location, and purchased care were associated with an increased likelihood of preoperative MRI utilization. Non-metropolitan location and Navy service branch were associated with decreased MRI use. CONCLUSION: After controlling for expected clinical risk factors, patients were more likely to receive additional MRI when treated at metropolitan facilities or through the fee-for-service system. Both associations may point toward non-clinical incentives to perform MRI in the treatment of breast cancer.

Use of low-value pediatric services in the Military Health System.

BACKGROUND: Low-value care (LVC) is understudied in pediatric populations and in the Military Health System (MHS). This cross-sectional study applies previously developed measures of pediatric LVC diagnostic tests, procedures, and treatments to children receiving care within the direct and purchased care environments of the MHS. METHODS: We queried the MHS Data Repository (MDR) to identify children (n = 1,111,534) who received one or more of 20 previously described types of LVC in fiscal year 2015. We calculated the proportion of eligible children and all children who received the service at least once during fiscal year 2015. Among children eligible for each measure, we used logistic regressions to calculate the adjusted odds ratios (AOR) for receiving LVC at least once during fiscal year 2015 in direct versus purchased care. RESULTS: All 20 measures of pediatric LVC were found in the MDR. Of the 1,111,534 eligible children identified, 15.41% received at least one LVC service, and the two most common procedures were cough and cold medications in children under 6 years and acid blockers for infants with uncomplicated gastroesophageal reflux. Eighteen of the 20 measures of pediatric LVC were eligible for comparison across care environments: 6 were significantly more likely to be delivered in direct care and 10 were significantly more likely to be delivered in purchased care. The greatest differences between direct and purchased care were seen in respiratory syncytial virus testing in children with bronchiolitis (AOR = 21.01, 95% CI = 12.23-36.10) and blood tests in children with simple febrile seizure (AOR = 24.44, 95% CI = 5.49-108.82). A notably greater difference of inappropriate antibiotic prescribing was seen in purchased versus direct care. CONCLUSIONS: Significant differences existed between provision of LVC services in direct and purchased care, unlike previous studies showing little difference between publicly and privately insured children. In fiscal year 2015, 1 in 7 children received one of 20 types of LVC. These proportions are higher than prior estimates from privately and publicly insured children, suggesting the particular need to focus on decreasing wasteful care in the MHS. Collectively, these studies demonstrate the high prevalence of LVC in children and the necessity of reducing potentially harmful care in this vulnerable population.

Prenatal use of medications for gastroesophageal reflux disease and early childhood fracture risk.

BACKGROUND: Gastroesophageal reflux disease is a common condition in pregnancy and is often managed with medications. Specific medications have been linked to osteoporosis and fragility fracture in older adults. This study assessed whether maternal use of antireflux medications is associated with early childhood fracture. METHODS: TRICARE beneficiaries during pregnancy were retrospectively identified using the Military Health System Data Repository and pharmacy data. Mother and infant data were linked; children with continuous enrollment for the first 5 years of life were included. Differences in the children's fracture risk were analyzed through multivariate analysis, adjusting for region, rank, and military branch of service. RESULTS: A total of 378 150 patients comprised the final cohort with 3.3% (n = 12 479) prescribed antireflux medications during pregnancy. A significant decrease in fracture rate was found among children of women who were prescribed antireflux medications during pregnancy compared with those who were not (0.8% vs 1.2%, RR = 0.70, 95% CI 0.58-0.85). There was no difference in fracture risk between histamine type 2 receptor antagonists and proton pump inhibitors. A significantly increased fracture incidence was seen in pregnancies with multiple gestations (RR = 1.38, 95% CI 1.04-1.85). There was no identified difference in fracture risk for women with gestational diabetes, preeclampsia, preterm or low birthweight, chronic hypertension, induction, or breech presentation when compared to women without these conditions. CONCLUSIONS: We found no increase in early childhood fracture risk with maternal antireflux medication use. This suggests that prenatal exposure to antireflux medications does not affect fetal bones to a clinically significant extent.

Early Pediatric Fractures in a Universally Insured Population within the United States.

BACKGROUND: Musculoskeletal injury, including fracture, is one of the most common causes of morbidity in pediatric patients. The purpose of this epidemiologic study is to determine the prevalence and risk factors for fracture in a large cohort of pediatric patients under the age of 5. RESULTS: Of the 233,869 patients included in the study, 13,698 fractures were identified in 10,889 patients. The highest annual incidence was in the 4 year old age group with a rate of 24.2 fractures per 1000 children. The annual incidence within all age groups was 11.7 fractures per 1000 children. The two most common fractures were forearm and humerus fractures. Fracture incidence was increased in male children, patients who live outside the US, and in Caucasian patients. An increase in rate of fracture was also identified in children of officers when compared with children of enlisted service members. There were 35 abuse related fractures in our cohort, with 19 of them occurring in children less than 1 year old. Only three children in our cohort had Osteogenesis Imperfecta. CONCLUSION: Fractures are common injuries in young children with an incidence over the first 5 years of life of 5.86%. Multiple risk factors were also identified including age, race, geographic location and socioeconomic status. The results of this study are an important contribution to epidemiologic and public health literature and serve to characterize the incidence of and risk factors for sustaining an early childhood fracture.

Racial Disparities in Highly Effective Contraceptive Use Among U.S. Active Duty Servicewomen, Fiscal Years 2016-2019.

Background: Previous studies have found that unintended pregnancy rates are higher among racial minorities and active duty servicewomen (ADSW), correlating with lower rates of effective contraceptive use. The Military Health System (MHS) provides universal health care benefit coverage for all ADSW, including access to all highly effective contraceptive (HEC) methods. This study investigated the association between race and HEC use among ADSW. Materials and Methods: We conducted a cross-sectional study using fiscal year 2016-2019 data from the MHS Data Repository for all ADSW ages 18-45 years. Statistical analyses included descriptive statistics and logistic regression models, adjusted and unadjusted, determining the odds of HEC use, overall and by method. Results: Of the 729,722 ADSW included in the study, 59.7% used at least one HEC during the study period. The highest proportions of users were aged 20-24 years, White, single, Junior Enlisted, and serving in the Army. Lower odds of HEC use were demonstrated in Black (odds ratio [OR] = 0.94, 95% confidence interval [CI] = 0.92-0.95), American Indian/Alaska Native (OR = 0.85, 95% CI = 0.82-0.89), Asian/Pacific Islander (OR = 0.81, 95% CI = 0.80-0.83), and Other (OR = 0.97, 95% CI = 0.94-0.99) ADSW compared with White ADSW. Conclusions: Universal coverage of this optional preventive service did not guarantee its use. The MHS can serve as a model for monitoring racial disparities in HEC use.

Vasectomy incidence in the military health system after the reversal of Roe v. Wade.

Dobbs v. Jackson Women's Health Organization (Dobbs decision) has already had profound impact on reproductive health care in the United States. Some studies have reported increased incidence of vasectomy after the Dobbs decision. The Military Health System (MHS) provides a unique opportunity to evaluate this relationship in a universally insured, geographically representative population. We conducted a retrospective cross-sectional study of vasectomies among all male beneficiaries in the MHS, ages 18 to 64, from 2018 to 2022. Beneficiaries receiving a vasectomy were identified via billing data extraction from the MHS Data Repository (MDR). Descriptive statistics of demographic factors of all those receiving a vasectomy in the study period were evaluated. Crude and multivariate logistic regression models were used to evaluate for differences in demographic variables in those receiving a vasectomy pre-Dobb's decision as compared to after the Dobb's decision. The total number of men receiving a vasectomy each month over the study period was analyzed, as were the numbers in a state immediately implementing abortion access restrictions (Texas), and one without any restrictions on abortion access (Virginia). Our analysis found that men receiving a vasectomy post-Dobbs decision were more likely to be younger, unmarried, and of junior military rank than prior to the Dobbs decision. In the months following the Dobbs decision in 2022 (June-December), there was a 22.1% increase in vasectomy utilization as compared to the averages of those months in 2018-2021. Further, it was found that the relative increase in vasectomy after the Dobbs decision was greater in Texas (29.3%) compared to Virginia (10.6%). Our findings highlight the impact of the Dobbs decision on reproductive health care utilization outside of abortion.

Diagnostic profiles associated with long-term opioid therapy in active duty servicemembers.

INTRODUCTION: Over-prescription of opioids has diminished in recent years; however, certain populations remain at high risk. There is a dearth of research evaluating prescription rates using specific multimorbidity patterns. OBJECTIVE: To identify distinct clinical profiles associated with opioid prescription and evaluate their relative odds of receiving long-term opioid therapy. DESIGN: Retrospective analysis of the complete military electronic health record. We assessed demographics and 26 physiological, psychological, and pain conditions present during initial opioid prescription. Latent class analysis (LCA) identified unique clinical profiles using diagnostic data. Logistic regression measured the odds of these classes receiving long-term opioid therapy. SETTING: All electronic health data under the TRICARE network. PARTICIPANTS: All servicemembers on active duty during fiscal years 2016 through 2019 who filled at least one opioid prescription. MAIN OUTCOME MEASURES: Number and qualitative characteristics of LCA classes; odds ratios (ORs) from logistic regression. We hypothesized that LCA classes characterized by high-risk contraindications would have significantly higher odds of long-term opioid therapy. RESULTS: A total of N = 714,446 active duty servicemembers were prescribed an opioid during the study window, with 12,940 (1.8%) receiving long-term opioid therapy. LCA identified five classes: Relatively Healthy (82%); Musculoskeletal Acute Pain and Substance Use Disorders (6%); High Pain, Low Mental Health Burden (9%); Low Pain, High Mental Health Burden (2%), and Multisystem Multimorbid (1%). Logistic regression found that, compared to the Relatively Healthy reference, the Multisystem Multimorbid class, characterized by multiple opioid contraindications, had the highest odds of receiving long-term opioid therapy (OR = 9.24; p < .001; 95% confidence interval [CI]: 8.56, 9.98). CONCLUSION: Analyses demonstrated that classes with greater multimorbidity at the time of prescription, particularly co-occurring psychiatric and pain disorders, had higher likelihood of long-term opioid therapy. Overall, this study helps identify patients most at risk for long-term opioid therapy and has implications for health care policy and patient care.

Analysis of Alcohol Use and Alcohol Use Disorder Trends in U.S. Active-Duty Service Women.

Introduction: Alcohol use (AU) and disorders (AUDs) have been increasing among women over the past decade, with the largest increases among women of child-bearing age. Unprecedented stressors during the COVID-19 pandemic may have impacted AU for women with and without children. Little is known about how these trends are impacting women in the military. Methods: Cross-sectional study of active-duty service women (ADSW) in the U.S. Army, Air Force, Navy, and Marine Corps during fiscal years (FY) 2016-2021. We report the prevalence of AU and AUD diagnoses by FY, before/during the COVID-19 pandemic (2016-2019; 2020-2021, respectively), and by parental status. Log-binomial and logistic regressions examined associations of demographics, military, and family structure characteristics, with AU and AUD, during pre-COVID-19 and COVID-19 timeframes. Results: We identified 281,567 ADSW in the pre-COVID-19 period and 237,327 ADSW in the during COVID-19 period. The prevalence of AU was lower during the COVID-19 period (47.9%) than during the pre-COVID-19 period (63.0%); similarly, the prevalence of AUD was lower during the COVID-19 period (2.7%) than during the pre-COVID period (4.0%). ADSW with children had larger percentage decreases during the COVID-19 period. ADSW with children had a consistently lower prevalence and odds of AUD compared with ADSW without children in the pre- and during COVID-19 periods. Conclusion: Decreasing trends in AU and AUD among ADSW were unexpected. However, the prevalence of AU and AUD may not have been accurately captured during the COVID-19 period due to reductions in access to care. Continued postpandemic comparison of AU/AUD among women by parental status and demographic factors may guide targeted health efforts.

Avoidable Hospitalizations in the Military Health System, Fiscal Years 2018-2019.

INTRODUCTION: Ongoing health reforms in the Military Health System (MHS) are expected to shift locations of ambulatory care for up to 1.9 million beneficiaries. We sought to model the impact of this policy by determining potentially avoidable hospitalizations in the MHS based on different primary care settings. MATERIALS AND METHODS: We used the MHS Data Repository to conduct a retrospective cross-sectional study of TRICARE Prime and Prime Plus beneficiaries aged 18 to 64 years during fiscal years 2018-2019. Crude and adjusted risk ratios for each Agency for Healthcare Research and Quality prevention quality indicator based on primary care setting were calcualated to determine the total probability of admission for any of the Agency for Healthcare Research and Quality prevention indicators. RESULTS: We identified a total of 260,690 hospital admissions by patients in the MHS with a designated primary care manager (PCM) from fiscal year 2018 to 2019. Of the total admissions, 11,067 (4.25%) were for Agency for Healthcare Research and Quality prevention quality indicators, 3.63% by direct care PCM at a military treatment facility, and 0.61% by a civilian private sector PCM. Risk of admission was lower for private sector PCMs for urinary tract infection, hypertension, perforated appendix, and angina without the procedure. We did not observe a statistically significant adjusted odds ratio of admission in patients managed by private sector PCMs (1.04 adjusted odds ratio; 95% CI, 0.97-1.11). CONCLUSIONS: Our findings indicate no difference in the likelihood of avoidable hospitalizations for beneficiaries with a private sector PCM when looking at all conditions together. Patients with a private sector PCM are protected against hospitalization for several conditions. Our findings indicate no adverse impact on avoidable hospitalizations for beneficiaries transitioned to private sector care from direct care.

Association between body composition standards and eating disorder medical claims among active-duty service women.

INTRODUCTION: Eating disorders are a worldwide public health concern with the United States having a particularly high prevalence. Eating disorders are of particular concern to the Department of Defense and Military Health System (MHS) because body composition standards are in place for active-duty service members. METHODS: We conducted a cross-sectional study of active-duty service women (ADSW) ages 18 and older in the U.S. Army, Air Force, Navy, and Marine Corps during fiscal years (FY) 2018-2019. Utilizing claims data from the MHS Data Repository (MDR), we identified ADSW with a Body Mass Index (BMI) measure during the study period and compared their BMI to Service-specific requirements and diagnosis of an eating disorder. RESULTS: We identified a total of 161,209 ADSW from the MDR in FYs 2018-2019 with a recorded BMI, of whom 61,711 (38.3%) had a BMI exceeding the maximum BMI Service-specific standards during the study period and 0.5% had an eating disorder diagnosis. Increased risk of an eating disorder was found in ADSW with an Underweight BMI. Further, we found that there was no association of disordered eating diagnoses among ADSW who were near the maximum height/weight standard set by their Service. CONCLUSION: There appears to be no association between body composition standards of the Services and eating disorder diagnoses in ADSW. We were not able to investigate unhealthy habits around diet or exercise directly related to body composition standards.

Eating disorders are a worldwide public health concern with the United States having a particularly high prevalence. Active duty service women serving in the United States armed forces may be at an increased risk due to strict Service specific weight requirements. This study suggests that the height and weight standards do not increase the risk for eating disorder diagnoses in active duty service women. However, we were not able to investigate unhealthy habits around diet or exercise directly related to body composition standards near the time of measurement or assessment.

Reductions in sustained prescription opioid use within the US between 2017 and 2021.

Over the last decade, various efforts have been made to curtail the opioid crisis. The impact of these efforts, since the onset of the COVID-19 pandemic, has not been well characterized. We sought to develop national estimates of the prevalence of sustained prescription opioid use for a time period spanning the COVID-19 pandemic (2017-2021). We used TRICARE claims data (fiscal year 2017-2021) to identify patients who were prescription opioid non-users prior to receipt of a new opioid medication. We evaluated eligible patients for subsequent sustained prescription opioid use. The prevalence of sustained prescription opioid use during 2020-2021 was compared to 2017-2019. We performed multivariable logistic regression analyses to adjust for confounding. We performed secondary analyses that accounted for interactions between the time period and age, as well as a proxy for socioeconomic status. We determined there was a 68% reduction in the odds of sustained prescription opioid use (OR 0.32; 95% CI 0.27, 0.38; p < 0.001) in 2020-2021 as compared to 2017-2019. Significant reductions were identified across all US census divisions and all patient age groups. In both time periods, the plurality of encounters associated with initial receipt of an opioid that culminated in sustained prescription opioid use were associated with non-specific primary diagnoses. We found significant reductions in sustained prescription opioid use in 2020-2021 as compared to 2017-2019. The persistence of prescribing behaviors that result in issue of opioids for poorly characterized conditions remains an area of concern.

The Comparative Effectiveness and Provider-induced Demand Collaboration Project: A Pioneering Military-Civilian Academic Partnership to Build Health Services Research Capacity for the Military Health System.

INTRODUCTION: Like civilian health systems, the United States Military Health System (MHS) confronts challenges in achieving the aims of reducing cost, and improving quality, access, and safety, but historically has lacked coordinated health services research (HSR) capabilities that enabled knowledge translation and iterative learning from its wealth of data. A military-civilian academic partnership called the Comparative Effectiveness and Provider-Induced Demand Collaboration (EPIC), formed in 2011, demonstrated early proof-of-concept in using the MHS claims database for research focused on drivers of variation in health care. This existing partnership was reorganized in 2015 and its topics expanded to meet the need for HSR in support of emerging priorities and to develop current and HSR capacity within the MHS. MATERIALS AND METHODS: A Donabedian framework of structure, process, and outcomes was applied to support the project, through a core of principal investigators, researchers, analysts, and administrators. Within this framework, new researchers and student trainees learn foundations of HSR while performing secondary analysis of claims data from the MHS Data Repository (MDR) focusing on Health and Readiness, Pediatrics, Policy, Surgery, Trauma, and Women's Health. RESULTS: Since 2015, the project has trained 25 faculty, staff, and providers; 51 students and residents; 21 research fellows across multiple disciplines; and as of 2022, produced 107 peer-reviewed publications and 130 conference presentations, across all five themes and six cores. Research results have been incorporated into Federal and professional policy guidelines. Major research areas include opioid usage and prescribing, value-based care, and racial disparities. EPIC researchers provide direct support to MHS leaders and enabling expertise to clinical providers. CONCLUSIONS: EPIC, through its Donabedian framework and utilization of the MHS Data Repository as a research tool, generates actionable findings and builds capacity for continued HSR across the MHS.

Development of Chronic Pain Conditions Among Women in the Military Health System.

Importance: The incidence of chronic pain has been increasing over the last decades and may be associated with the stress of deployment in active-duty servicewomen (ADSW) as well as women civilian dependents whose spouse or partner served on active duty. Objective: To assess incidence of chronic pain among active-duty servicewomen and women civilian dependents with service during 2006 to 2013 compared with incidence among like individuals at a time of reduced combat exposure and deployment intensity (2014-2020). Design, Setting, and Participants: This cohort study used claims data from the Military Health System data repository to identify ADSW and dependents who were diagnosed with chronic pain. The incidence of chronic pain among individuals associated with service during 2006 to 2013 was compared with 2014 to 2020 incidence. Data were analyzed from September 2023 to April 2024. Main Outcomes and Measures: The primary outcome was the diagnosis of chronic pain. Multivariable logistic regression analyses were used to adjust for confounding, and secondary analyses were performed to account for interactions between time period and proxies for socioeconomic status and combat exposure. Results: A total of 3 473 401 individuals (median [IQR] age, 29.0 [22.0-46.0] years) were included, with 644 478 ADSW (18.6%). Compared with ADSW in 2014 to 2020, ADSW in 2006 to 2013 had significantly increased odds of chronic pain (odds ratio [OR], 1.53; 95% CI, 1.48-1.58). The odds of chronic pain among dependents in 2006 to 2013 was also significantly higher compared with dependents from 2014 to 2020 (OR, 1.96; 95% CI, 1.93-1.99). The proxy for socioeconomic status was significantly associated with an increased odds of chronic pain (2006-2013 junior enlisted ADSWs: OR, 1.95; 95% CI, 1.83-2.09; 2006-2013 junior enlisted dependents: OR, 3.05; 95% CI, 2.87-3.25). Conclusions and Relevance: This cohort study found significant increases in the diagnosis of chronic pain among ADSW and civilian dependents affiliated with the military during a period of heightened deployment intensity (2006-2013). The effects of disparate support structures, coping strategies, stress regulation, and exposure to military sexual trauma may apply to both women veterans and civilian dependents.

Digoxin and Standard-of-Care Therapy for Heart Failure Patients with COVID-19: Analysis of Data from the US Military Health System (MHS) Data Repository.

BACKGROUND: Cardiac glycosides such as digoxin, digitoxin and ouabain are still used around the world to treat patients with chronic heart failure with reduced ejection fraction (HFrEF) and/or atrial fibrillation (AF). However, in the US, only digoxin is licensed for treating these illnesses, and the use of digoxin for this group of patients is increasingly being replaced in the US by a new standard of care with groups of more expensive drugs. However, ouabain and digitoxin, and less potently digoxin, have also recently been reported to inhibit SARS-CoV-2 virus penetration into human lung cells, thus blocking COVID-19 infection. COVID-19 is known to be a more aggressive disease in patients with cardiac comorbidities, including heart failure. OBJECTIVE: We therefore considered the possibility that digoxin might provide at least a measure of relief from COVID-19 in digoxin-treated heart failure patients. To this end, we hypothesized that treatment with digoxin rather than standard of care might equivalently protect heart failure patients with regard to diagnosis of COVID-19, hospitalization and death. METHODS: To test this hypothesis, we conducted a cross-sectional study by using the US Military Health System (MHS) Data Repository to identify all MHS TRICARE Prime and Plus beneficiaries aged 18-64 years with a heart failure (HF) diagnosis during the period April 2020 to August 2021. In the MHS, all patients receive equal, optimal care without regard to rank or ethnicity. Analyses included descriptive statistics on patient demographics and clinical characteristics, and logistic regressions to determine likelihood of digoxin use. RESULTS: We identified 14,044 beneficiaries with heart failure in the MHS during the study period. Of these, 496 were treated with digoxin. However, we found that both digoxin-treated and standard-of-care groups were equivalently protected from COVID-19. We also noted that younger active duty service members and their dependents with HF were less likely to receive digoxin compared with older, retired beneficiaries with more comorbidities. CONCLUSION: The hypothesis of equivalent protection by digoxin treatment of HF patients in terms of susceptibility to COVID-19 infection appears to be supported by the data.
