  • cost-to-charge ratio
  • number of beds
  • medicare discharges
  • MSA, CBSA, SSA state and county, Census division or region, urban/rural

A researcher kindly shared the 1986-1993 data from long ago downloads.

Jean Roth gathered many source files and documentation and set up the impact[CCYY].[dta|sas7bdat|csv] versions of the source Impact files with consistent file and variable names and variable types over time to make the files easier to use. Additional source materials gratefully accepted.
