Abstract

Disparities in primary care access among Medicaid enrollees may be driven by differences in provider acceptance of Medicaid, yet the extent to which primary care provider (PCP) panels reflect the racial and ethnic diversity of local Medicaid populations is unknown. : To quantify the alignment between the racial/ethnic composition of PCP Medicaid panels and the underlying Medicaid population in their service areas. : We conducted a cross-sectional analysis of 2019 Transformed Medicaid Statistical Information System Analytic Files from 44 states focusing on non-Hispanic White (NHW), non-Hispanic Black (NHB), and Hispanic enrollees. We calculated a panel representation ratio (PRR) for each PCP (physicians, nurse practitioners, and physician associates) as the proportion of a racial/ethnic group in their panel divided by that group's proportion in the county Medicaid population. PRRs > 1 indicate overrepresentation; PRRs < 1, underrepresentation. Analyses were stratified by provider specialty, rurality, and Health Professional Shortage Area (HPSA) status. : The study sample included 372,320 PCPs from the following professions: nurse practitioners (NPs) and physician associates (PAs), along with physicians from the following specialties: family physicians (FPs), internal medicine physicians (IM), obstetrician gynecologists (ObGyn), and pediatricians (Peds). In the full sample, PRR was 1.28 for NHW enrollees, but less than one for NHB (0.98) and Hispanic (0.82) enrollees. Across provider specialties and professions, NHW enrollees were overrepresented in both rural and urban areas. In rural areas, NHB enrollees were overrepresented, but Hispanic enrollees remained underrepresented regardless of Health Professional Shortage Area (HPSA) status. In urban areas, both NHB and Hispanic enrollees were underrepresented in provider panels. : Medicaid PCP panels do not reflect the racial/ethnic diversity of local Medicaid populations, particularly for NHB and Hispanic enrollees in urban settings. Efforts to improve equitable access to primary care must address these disparities in provider panel composition.
