Racial-ethnic composition of primary care practices and Comprehensive Primary Care Plus initiative participation.
The purpose of this study was to explore whether primary care practices serving high rates of Black or Latino Medicare fee-for-service (FFS) beneficiaries were less likely to participate in CPC+ in 2021 compared to practices serving lower rates of these same populations. 11,718 primary care practices and 7,264,812 attributed Medicare FFS beneficiaries across 18 eligible regions participated in the study. The study found that 26.9% of the eligible practices were CPC+ participants. In statistically adjusted analyses, primary care practices with high shares of Black and Latino beneficiaries had a lower likelihood of participating in CPC+ compared to practices with lower shares of these beneficiary groups. Participation disparities for practices with relatively high shares of Black beneficiaries partially explained state differences in CPC+ participation rates but did not explain participation disparities for practices with relatively high shares of Latino beneficiaries.

Association between hospital-physician vertical integration and medication adherence rates.
This study’s goal was to test the association between vertical integration of primary care providers (PCPs) and adherence rates for anti-diabetics, renin angiotensin system antagonists (RASA), and statins. Data was extracted from Medicare Part B outpatient fee-for-service claims and Medicare Part D event data from 2014 to 2017. There was a 23% increase in the proportion of patients who had a vertically integrated PCP during the study period. Changes in adherence did not differ significantly between patients based on whether their PCP became integrated. However, among patients with PCPs who become integrated, there were significant decreases in patients who were above 80 years old, were Black, Asian, Hispanic, or Native America, and had greater comorbidities for all three classes.
