Journal of Ambulatory Care Management: April/June 2019 - Volume 42 - Issue 2 - p 92-104 doi: 10.1097/JAC.0000000000000269 Buy Metrics Abstract To help health care practices transition away from fee-for-service reimbursement and toward value-based payment, the Transforming Clinical Practice Initiative was launched in October 2015. It was designed to provide clinicians support through peer-based Practice Transformation Networks (PTNs). A group of American Board of Family Medicine board-certified family physicians enrolled in PTNs described their expectations of and experiences with PTN participation; we analyzed open-text comments. Physicians expected and experienced PTN support in informatics and data, team building, and workflow and care coordination; however, expectations regarding patient care and engagement, costs and payment reform, and population and panel health were described less frequently. © 2019 Wolters Kluwer Health, Inc.
