This study evaluated differences in racial and ethnic disparities in surgical outcomes between Medicare Advantage and traditional Medicare beneficiaries, finding consistent but nonuniform smaller disparities within Medicare Advantage.

Among near-poor Black and Hispanic individuals, Medicare Advantage was associated with increased vision care and some, although not uniform, reductions in access disparities vs traditional Medicare.

In the era after Medicaid expansion, primary care providers placed importance on practice capacity, specialist availability, and reimbursement when deciding whether to accept new Medicaid patients.

After Medicaid expansion in Michigan, appointment availability for new Medicaid patients stably increased-this is perhaps attributable to increasing proportions of appointments scheduled with nonphysician providers.

Primary care physicians using more health information technology were less likely to accept new patients.
