The final evaluation of the Comprehensive Primary Care (CPC) initiative published in Health Affairs in June described the project and concluded that it “did not reduce Medicare [emphasis added] spending enough to cover care management fees or appreciably improve physician experience.” The CPC initiative required participating primary care practices to implement five primary care functions: enhanced access to and continuity of care, planned care for chronic conditions and preventive care, risk-stratified care management, patient and caregiver engagement, and coordination of care with patients’ other providers. CPC supported the practices with enhanced payments, data feedback on patient outcomes, and learning support.
