Racial Differences in Severe Maternal Morbidity Exist for Tricare Beneficiaries [ID: 1377133]

INTRODUCTION: Maternal morbidity and mortality rates in the United States have increased in the last two decades with a disproportionate effect on women of color. Military Tricare coverage models universal health care access; however, in studies looking at births in military treatment facilities, disparities still exist for women of color. This study analyzes maternal delivery outcomes for all women with Tricare coverage including deliveries in the civilian sector. METHODS: Data from 6.2 million births in the Centers for Disease Control and Prevention WONDER Linked Birth/Infant Death Records for 2017–2019 were analyzed for all-cause morbidity (transfusions, perineal lacerations, uterine rupture, unplanned hysterectomy, and intensive care unit admissions), severe maternal morbidity (SMM) (excludes lacerations), and SMM excluding transfusion. Risk ratios were calculated comparing overall maternal morbidity rates between Tricare, Medicaid, self-pay, and private insurance. In addition, risk ratios were calculated between insurance types stratified by race. RESULTS: Compared to private insurance, Tricare insurance had significantly reduced risk of all-cause maternal morbidity. Compared to White women, Black women with Tricare and all other insurances had a decreased risk of all-cause morbidity, but a significantly increased risk of SMM and SMM without transfusion. Asian women had significant increased risk of all-cause, SMM and SMM without transfusion. There was no significant difference in the risk of morbidity for women of color with Tricare insurance compared to women of color with Medicaid, private, or self-pay insurance. CONCLUSION: The risk of severe maternal morbidity remains elevated for women of color despite access to Tricare health insurance.
