This is an analytic flat file that used hospital-specific identifiers to link data from multiple publicly available sources. First, we obtained data on hospital performance on the SEP-1 measure from Medicare’s Hospital Compare website, which publicly reports quality data for hospitals participating in Medicare’s Inpatient Quality Reporting Program (IQRP). The SEP-1 data were reported for the period from January 1, 2017 to September 30, 2017. Second, we obtained data on hospital financial case-mix from the Provider Specific File for public use, which contains information on the proportion of Medicare days accounted for by patients receiving supplemental security income (SSI) payments, the proportion of Medicaid days, and total uncompensated care payments. These data were from the October 2018 update. Third, we obtained data on hospital organizational characteristics from Medicare’s Healthcare Cost Reporting Information System (HCRIS). We used HCRIS data from 2016, the most recent year that reliable data were available. Fourth, we used the Medicare Impact File to obtain information on hospitals’ urban and rural status, as indicated by the US Bureau. Finally, we obtained data on hospitals’ affiliation with health systems from the Compendium of U.S. Health Systems 2016, published by the Agency for Healthcare Research and Quality (AHRQ) as part of the Comparative Health Systems Performance (CHSP) initiative. This dataset contains curated information on U.S. health care delivery systems, including whether a hospital is affiliated with a health system. See accompanying manuscript for description of hospital selection criteria and variable definitions.
