The Impact of Population Health Analytics on Health Care Quality and Efficacy Among CPC+ Participants

Multipayer Primary Care Network Primary Care Transformation Population Health


Analysis of the Comprehensive Primary Care (CPC) program found that the lack of infrastructure for health information exchange was a barrier for primary care practices participating in this federal multipayer advanced primary care program. This study examines whether population health management information technologies offered through a health information exchange (HIE) platform—which collects and stores data across providers—helped practices in the follow-up program, Comprehensive Primary Care Plus (CPC+), achieve better outcomes. We conducted a retrospective study to examine several outcome measures among a sample of 37 participating primary care practices in western New York. These practices were grouped in four categories based on their participation in CPC+ and population health information technology services. Over the course of January 2020 to December 2020, practices with membership in both CPC+ and HIE  saw  24.1% lower risk-adjusted hospital admission rates and 21.0% lower risk-adjusted outpatient surgery rates compared with practices that didn’t participate in either one. Average lengths of stay in hospitals were 32.7% lower and readmission rates were 30.4% lower. Given these observations, which are based on a robust and mature HIE system, we encourage the medical practices that participated in the CPC+ program or are engaged in other multipayer advanced primary care opportunities to also subscribe to population health management information technologies.
