P opulation-based hospital payments provide incentives to reduce unnecessary healthcare use and a mechanism to finance population health investments. For hospitals, these payments provide stable revenue and flexibility in exchange for increased financial risk. The COVID-19 pandemic significantly reduced fee-for-service revenues, which has spurred provider interest in population-based payments, particularly from cash-strapped rural hospitals.The Centers for Medicare & Medicaid Services (CMS) recently announced the launch of the Community Health Access and Rural Transformation (CHART) Model to test whether up-front, population-based payments improve access to high-quality care in rural communities and protect the financial stability of rural providers. This model follows the ongoing Pennsylvania Rural Health Model (PARHM), which offers similar payments to Pennsylvania's rural hospitals. Prospective population-based hospital reimbursement appears to have helped Maryland's hospitals survive the financial stress of the COVID-19 pandemic, 1 and it is likely that the PARHM did the same for rural hospitals in Pennsylvania. Both the PARHM and the CHART Model place quality measurement and improvement at the core of payment reform, and for good reason. Capitation generates incentives for care stinting; linking prospective payments to quality measurement helps to ensure accountability. However, measuring the quality of rural healthcare is challenging. Rural health is different: Hospital size, payment mechanisms, and community health priorities are all distinct from those of metropolitan areas, which is why CMS exempts Critical Access Hospitals from Medicare's core quality programs. Rural quality reporting programs could be established that address the unique aspects of rural healthcare.As designers (JEF, DTL) of, and an advisor (ALS) for, a proposed pay-for-performance (P4P) program for the PARHM, 2 we identified three central challenges in constructing and implementing P4P programs for rural hospitals, along with potential solutions. We hope that the lessons we learned can inform similar policy efforts.First, many rural hospitals serve as stewards of community health resources. While metropolitan hospital systems can make
