Table only displays adjusted odds ratios for independent variables. Covariates included rural location, medical school affiliation, system affiliation, ownership status, size, safety-net status, the number of full-time equivalent registered nurses per 1,000 patient-days, the percentage of discharges reimbursed by Medicare, the percentage of county residents living below the poverty line, and the percentage of county residents that are Black.

Various states omitted, because all AHA Care Systems and Payment Survey participating hospitals in state received low-performance score or high-performance score.
