Medicare beneficiaries with more comprehensive primary care physicians report better primary care

ObjectiveTo examine whether primary care physician (PCP) comprehensiveness is associated with Medicare beneficiaries' overall rating of care from their PCP and staff. Data SourcesWe linked Medicare claims with survey data from Medicare beneficiaries attributed to Comprehensive Primary Care Plus (CPC+) physicians and practices. Study DesignWe performed regression analyses of the associations between two claims-based measures of PCP comprehensiveness in 2017 and beneficiaries' rating of care from their PCP and practice staff in 2018. Data Collection/Extraction MethodsThe analytic sample included 6228 beneficiaries cared for by 3898 PCPs. Regressions controlled for beneficiary, physician, practice, and market characteristics. Principal FindingsBeneficiaries with more comprehensive PCPs rated care from their PCP and practice staff higher than did those with less comprehensive PCPs. For each comprehensiveness measure, beneficiaries whose PCP was in the 75th percentile were more likely than beneficiaries whose PCP was in the 25th percentile to rate their care highly (2 percentage point difference, p = 0.02). ConclusionsMedicare beneficiaries with more comprehensive PCPs rate overall care from their PCPs and staff higher than those with less comprehensive PCPs.
