Changes in the Composition and Affiliation of the US Primary Care Workforce and Ownership of Primary Care Clinical Sites, 2020–2023

The US PC landscape is increasingly dominated by health systems and large corporations, with these organizations accounting for all the growth in the physician workforce between 2020 and 2023. Despite a growing workforce, the reduction in PC sites, particularly in rural areas, may negatively impact PC access. These findings suggest the need for an accessible data source for monitoring the effects of policies intended to increase the PC workforce and examining how patterns of PC site ownership affect healthcare costs and quality.
