Initially, 484 hospitals were omitted from the 2011-2015 HCRIS
data for duplicate cost reports, which was less than two percent of all hospitals that submitted a cost report from 2011-2015 (n = 29 518).
As with HCRIS
reports, these are almost always aggregated and not by individual procedures.
CMS would then need to store the data in HCRIS
, and make them available as they do for other parts of the cost report.
Third, the Online Survey Certification and Reporting (OSCAR) Certification and Survey Provider Enhanced Reporting (CASPER) data were merged with HCRIS
and the Five-Star Quality Rating System using the provider identifier.
CMS manages the database through the Healthcare Cost Report Information System (HCRIS
) (Hospital Cost Report 2005).
These variables were obtained from HCRIS
. We also included the Saidin index, a measure of technological sophistication (Spetz and Maiuro 2004), which was derived from AHA data.
Hospital net patient revenue, costs, investment income, and cost-to-charge ratios were drawn from the Center for Medicare & Medicaid Services Healthcare Cost Report Information System (HCRIS
Two files from HCFA were used for the analysis: the Medicare Provider Analysis and Review File (MEDPAR) for calendar year 1988 and the Hospital Cost Reporting Information System (HCRIS
) for FYs 1985 through 1988.
We linked eligible hospitalizations to the 2006 Healthcare Cost Report Information System (HCRIS
) data from the Center for Medicare and Medicaid Services (2006).
Hospital data were obtained from four files: the Medicare Hospital Cost Report Information System (HCRIS
), the Provider Specific file, the American Hospital Association (AHA) 1987 Annual Survey file, and the HCFA wage-index file.
Time period variables are constructed based on the proportion of days in a Healthcare Cost Report Information System (HCRIS
) reporting period falling in the respective periods.
A data base was constructed from the Hospital Cost Report Information System (HCRIS
) and provider-specific files.
