Key Points Question What type of primary care practices join the Comprehensive Primary Care Plus program, and which patient populations do those practices serve? Findings This comparative cross-sectional study of 756 areas eligible for the Comprehensive Primary Care Plus program found that a diverse set of primary care practices joined the program. Practices located in wealthier areas with higher education levels and less use of inpatient services were more likely to join. Meaning Voluntary advanced primary care medical home models, such as the Comprehensive Primary Care Plus program, may leave behind practices serving vulnerable populations.
