Findings from Brown University Provides New Data on Managed Care (Low-Value Care Following Hospital and Private Equity Acquisition in Primary Care): Managed Care

Brown University researchers analyzing Medicare claims data have published findings on how private equity acquisitions reshape primary care practice operations and utilization patterns. The study, published in JAMA Health Forum, tracked outcomes across primary care practices acquired by PE firms and compared them to non-acquired peers, providing institutional investors with empirical data on PE's operational impact in healthcare.

The research reveals that PE ownership drives measurable expansion in clinical throughput. Following acquisition, primary care physicians increased the number of services billed by 30 percent and the number of patients seen by 11 percent. These metrics suggest that PE ownership implements efficiency protocols and scaling strategies typical of financial sponsors seeking margin improvement and revenue growth. However, this expansion occurred without significant changes to patient composition, indicating that increased utilization reflects operational restructuring rather than shifts in the patient population served.

A critical finding for investors concerns low-value care—a key metric for assessing whether PE ownership compromises clinical quality or drives unnecessary spending. The Brown research found that hospital and PE acquisitions in primary care did not result in significant changes to the likelihood or number of low-value care services. This outcome contradicts some assertions that PE ownership incentivizes excessive billing; instead, it suggests that PE acquirers maintain baseline clinical standards while pursuing volume-based revenue strategies. Additionally, PE acquisitions were associated with modest reductions in emergency department visits, though the magnitude remains limited relative to the overall increase in primary care utilization.

The scale of PE investment in healthcare consolidation underscores the financial stakes driving these acquisitions. Between 2018 and 2022, private equity firms invested $446 billion in healthcare, with ownership expanding rapidly across hospitals, primary care practices, and ancillary care settings. For hedge funds and family offices evaluating exposure to PE-backed healthcare operators or considering direct healthcare investments, the Brown data suggests that PE ownership generates operational leverage through volume expansion while maintaining clinical utilization patterns. However, the absence of dramatic cost reductions or quality improvements indicates that value creation in PE-backed primary care relies on efficiency gains and revenue scaling rather than fundamental clinical innovation.
