    Open AccessYoungMin Kwon, Shelley A Jazowski et al.ARTICLEJAMA Health Forum2025

    In this cohort study, state Medigap guaranteed issue protections were associated with higher rates of switching to TM among MA beneficiaries newly diagnosed with cancer. These findings underscore the protective association of state Medigap regulations in facilitating a switch to TM (especially among beneficiaries who likely desired more flexibility in accessing and receiving care) and illuminate potential disparities in switching that may reflect…

    Open AccessDennis Lee, Stacie B Dusetzina et al.ARTICLEJAMA Health Forum2025

    Open AccessRobert J Dambrino, Henry J Domenico et al.ARTICLEJAMA Health Forum2023

    In this cohort study, implementation of the Cures Act IBR was not associated with an increase in monthly rates of UPCs.

    BACKGROUND: Little is known about the geographic distribution of the overall primary care workforce that includes both physician and nonphysician clinicians--particularly in areas with restrictive nurse practitioner scope-of-practice laws and where there are relatively large numbers of uninsured. OBJECTIVE: We investigated whether geographic accessibility to primary care clinicians (PCCs) differed across urban and rural areas and across states wi…

  • Measuring Returns to Hospital Care

    Joseph J Doyle, Joseph Doyle et al.ARTICLEJournal of Political Economy2015Cited by: 6

    Medicare spending exceeds 4% of GDP in the US each year, and there are concerns that moral hazard problems have led to overspending. This paper considers whether hospitals that treat patients more aggressively and receive higher payments from Medicare improve health outcomes for their patients. An innovation is a new lens to compare hospital performance for emergency patients: plausibly exogenous variation in ambulance-company assignment among pa…

Using a county-based measure of managed care enrollment and pooled data from the 1997 to 2004 National Health Interview Surveys, we investigate whether Medicaid managed care (MMC), relative to FFS Medi…
