This document summarizes research identifying "Bright Spot" primary care practices that achieve high quality scores and low total costs of care. Key findings include: - Researchers identified 11 primary care practices ranked in the top quartile for both quality and costs over 20% lower than average. - Bright Spot practices were found in different reimbursement models and market settings. They employed team-based care, took wider responsibility for patients, and had deeper relationships. - Shared features included upskilled staff roles, balanced compensation, and focus on people over space/equipment. Further research and payment reforms are needed to spread these approaches.
