Medicaid Managed Care Network Adequacy and Its Impact on Access to Care for Pregnant Women with Opioid Use Disorder - PROJECT SUMMARY The long-term goal of this K01 is to provide the mentorship and training necessary for Dr. Auty to become an independent investigator examining how Medicaid Managed Care (MMC) networks and policies influence access to care and health outcomes for individuals with opioid use disorder (OUD) and other substance use disorders (SUD). This K01 will focus specifically on how MMC networks impact access to care and outcomes for pregnant women with opioid use disorder (PwOUD). PwOUD face more than double the risk of severe maternal morbidity, life-threatening complications related to pregnancy and delivery, compared to pregnant women without OUD. Maternity care and medications for opioid use disorder (MOUD) mitigate the risk of adverse maternal health outcomes, yet less than half of PwOUD use both these services before delivery. MMC plans, which provide benefits to >70% of Medicaid-enrolled PwOUD, are required to meet state-defined network adequacy standards but these standards vary widely and are often unenforced, potentially creating critical gaps in access to care. There is no evidence on if MMC provider networks are sufficient to meet the needs of PwOUD, nor if network adequacy policies improve care access or health outcomes for PwOUD—an evidence gap that hinders policy efforts to improve the health of this group. This K01 aims to (1) measure the adequacy of MMC maternity and MOUD provider networks using standard metrics and innovative spatial methods, (2) evaluate geographic variation in network adequacy based on PwOUD status, and (3) estimate the impact of state policies that enforce network adequacy standards through financial penalties on service utilization and outcomes for PwOUD. To achieve these aims and become a successful independent investigator at the forefront of MMC research, Dr. Auty will pursue three key training objectives: (1) network measurement, (2) spatial analysis, and (3) machine learning methods. These skills will enable her to assess the complex interaction between Medicaid policies, provider networks, and access to care and health outcomes among PwOUD and other high-priority groups. This work aligns with The National Institute of Drug Abuse’s interest in research evaluating how policies (NOT-OD-24-079) and payment mechanisms (NOT-MH- 24-270) impact the use of health services and outcomes among those with OUD. Moreover, this proposal will equip Dr. Auty with essential training and generate important evidence to improve the health of PwOUD, while laying the groundwork for future R01 research on the impact of MMC networks and related policies on outcomes for Medicaid enrollees with OUD and other SUDs.
