Health System Affiliation and Care for Dual-Eligible and Non-Dual-Eligible Medicare Beneficiaries.

ABSTRACT:

Importance

Physician organization (PO) affiliation with health systems and its association with health care disparities for dual-eligible Medicare and Medicaid beneficiaries, who face significant barriers to care, remains underexplored.

Objectives

To estimate the association of health system affiliation with disparities in quality of care and health care utilization for dual-eligible beneficiaries relative to non-dual-eligible Medicare beneficiaries and to decompose these associations into within-PO and between-PO components.

Design, setting, and participants

This cohort study used data from 2013 to 2019 on primary care POs and beneficiaries enrolled in traditional Medicare. Statistical analysis was performed from April 2024 to March 2025.
