Brief summary: The Comprehensive Primary Care Plus (CPC+) Model, sponsored by the Centers for Medicare \& Medicaid Services (CMS), is a multipayer advanced primary care model. CPC+ aims to strengthen primary care by transforming how primary care practices deliver care, supported by regionally based multipayer payment reform, learning support, data feedback, and health information technology (health IT) support. The CPC+ evaluation will assess how CPC+ was implemented; how practices transformed care; and the effects on cost, service use, quality of care, and the experiences of patients, primary care practitioners, and staff. The evaluation will also identify facilitators and barriers to implementation and improved outcomes.

Detailed description: This project is a large, seven-year mixed-methods evaluation of the Comprehensive Primary Care Plus (CPC+) Model, sponsored by the Centers for Medicare \& Medicaid Services (CMS). CPC+ aims to improve the delivery of primary care; patients' cost, service use, and quality of care; and the experiences of patients, practitioners, and staff. It aims to achieve these goals by helping practices transform across five key care delivery functions: (1) access and continuity, (2) care management, (3) comprehensiveness and coordination, (4) patient and caregiver engagement, and (5) planned care and population health.

The national model includes two rounds, each of which will last for five years. Round 1 will take place from January 2017 through December 2021 and Round 2 from January 2018 through December 2022. A total of 2,877 primary care practices are participating in Round 1. The number of Round 2 practices will not be confirmed until September 2017.

From practices that applied to participate, CMS selected those that provide primary care, met specific certified health information technology (health IT) requirements, and were already engaging in certain care delivery activities. The CPC+ model includes two transformation tracks with incrementally advanced care delivery requirements and payment options. Participating practices will receive financial payments from CMS, including a monthly care management fee and prospective performance-based incentive payment, on top of traditional payments. Some practices will also receive some payment that shifts away from fee-for-service. In addition, practices will receive payments from other participating payers, representing a large proportion of their total revenue. CPC+ practices will receive learning support, data feedback, and health IT support to promote transformation.

To estimate the effect of CPC+, the investigators will compare the outcomes over time for CPC+ practices with the outcomes over time for a group of comparison practices. The investigators selected the comparison practices by identifying practices that matched the CPC+ practices on key characteristics. The investigators expect to include up to 8,397 comparison practices in Round 1.

The investigators will estimate the impact of CPC+ on patient outcomes by tracking the patients who are attributed to a study practice based on receiving most of their evaluation and management care from that practice. The investigators expect to include approximately 5,326,531 attributed patients across the CPC+ and comparison practices in Round 1 (the number of attributed patients for the Round 2 practices is to be determined). Analyses of Medicare (and in some regions Medicaid) claims data for patients attributed to the CPC+ and comparison practices will be conducted to estimate impacts on Medicare expenditures, our primary outcome, and service use and quality of care.

The investigators will also estimate the impact of CPC+ on practice care delivery approaches, and patient, practitioner, and staff experience. The investigators will administer a practice survey to the practice managers of all the study practices to track changes in care delivery and practice characteristics. The investigators will measure patient experience through a survey administered to Medicare fee-for-service beneficiaries attributed to the study practices. Changes in work environment and practitioner and staff experience with CPC+ will be measured through a survey of primary care practitioners of the study practices and staff of the CPC+ practices. For the Round 1 practices, the investigators expect to administer 11,244 practice surveys, 20,000 patient surveys, 10,996 practitioner surveys, and 10,429 staff surveys, The sample sizes for surveys for the Round 2 practices are to be determined. Telephone interviews and site visits will be conducted with CPC+ payers; practitioners and staff in the practices, and, if relevant, the systems and medical groups that own them; patients; and other stakeholders to understand what was implemented, and barriers and facilitators to implementation and improved outcomes.

Eligibility criteria: Inclusion Criteria:

* All Medicare fee-for-service patients who receive the largest share of their evaluation and management visits from one of the study primary care practices.
* Practice managers, practitioners, and staff of the study primary care practices.
