Over 70% of physicians are now employed by a health care system or corporate entity, including publicly traded and private equity firms. Research to date shows that consolidation has increased health care prices with limited impact on quality or access to care. Yet the impact of consolidation is highly heterogeneous across market conditions. Research at CAHPR aims to inform policy by understanding this evolving landscape that has critical implications for competition, choice, access, and the structure of health care services.

Dr. Yashaswini Singh, Assistant Professor at Brown University, presented findings from a study on private equity (PE) in Maryland physician practices, mandated by Maryland’s 2024 legislation (HB 1388).
