The Effects of the Medicaid Continuous Coverage Requirement during the Public Health Emergency on Postpartum Coverage and Maternal and Infant Care after Childbirth

PROJECT SUMMARY/ABSTRACT Career Goal: My long-time career goal is to become an independent investigator studying the effects of health care policies on access and use of maternal and infant health care services among low-income populations. With additional skills in claims data, subject matter expertise, and causal inference methods, I plan to build a

career focused on generating evidence to improve maternal and child health outcomes and reduce disparities in the United States. Career Development: I will pursue the following training aims during the mentored (K99) phase of the award: (1) clinical maternal and infant health content expertise; (2) claims data analysis skills; (3)

advanced causal methods, and; (4) professional development. Research Project: Extending postpartum Medicaid has the potential to address poor maternal health in the United States, with additional implications for infant care use and health.1 Approximately 63% of maternal deaths in the U.S. occur postpartum, and more

than half are considered to be preventable.2 However, despite high postpartum healthcare needs, pregnancy- related Medicaid ends after 60 days postpartum. Medicaid pays for almost half of all births in the US and disproportionately covers births to the low-income population and people of color.3–5 There has recently been

increased interest in postpartum Medicaid, including an American Rescue Plan (ARP) option to extend Medicaid one-year postpartum.6 Prior to this, the March 2020 Families First Coronavirus Response Act (FFCRA) prevented Medicaid disenrollment during the pandemic, thereby extending postpartum Medicaid

eligibility, which can inform current postpartum Medicaid policies under consideration. Using the Rhode Island All-Payer claims data, this proposal's Specific Aims are: K99/1) To evaluate the effects of the FFCRA on coverage and maternal and infant care in the postpartum period, R00/2) To evaluate the heterogeneous effects

of the FFCRA on outcomes by race and ethnicity, R00/3) To evaluate how the COVID-19 pandemic affected the effects of extended postpartum Medicaid eligibility on care use. Mentorship: I have assembled a highly accomplished team of experts at Brown University to provide mentorship and guidance as I transition to

research independence, comprised of Dr. Trivedi, Professor in the Department of Health Services, Policy and Practice and Department of Medicine; Dr. Steenland, Research Assistant Professor of Population Studies in the Population Studies and Training Center; Dr. Vivier, Professor of Health Services, Policy and Practice and

Professor of Pediatrics and Emergency Medicine; Dr. Wilson, Professor and Chair of the Department of Health Services, Policy and Practice, and Professor of Medicine; Dr. Savitz, Professor of Epidemiology and Professor of Obstetrics and Gynecology and Pediatrics; and Dr. Tuuli, Chace-Joukowsky Professor and Chair of

Obstetrics & Gynecology. Future Directions: The training and research in this proposal will provide me with a unique set of expertise and skills to prepare me to reach research independence and submit an R01 application to examine the effects of state variation in postpartum Medicaid policies using claims data.
