Evaluation of Comprehensive Primary Care Plus Model

This document is an evaluation report of the Comprehensive Primary Care Plus (CPC+) model, which was the largest primary care payment and delivery reform initiative tested in the United States. The report outlines the objectives of CPC+, which included transforming primary care practices through multipayer payment reform, actionable data feedback, and health information technology support. It details the structure of CPC+, including two tracks with varying requirements and financial support. The evaluation focuses on practices that joined in 2017, representing 95% of all CPC+ practices, and examines the impact on emergency department visits and hospitalizations. Key findings indicate that while CPC+ reduced certain acute care utilization measures, it did not achieve overall savings in Medicare expenditures. The report also discusses the support provided by CMS and payer partners, the utility of these supports, and the plans of practices to sustain improvements after the model's conclusion. Overall, the evaluation highlights the challenges faced in transforming primary care and the need for continued support.
