Crosswalk files

Our ZIP code to HSA to HRR crosswalk files allow you to aggregate data you may have at the ZIP code level to the hospital service area (HSA) or hospital referral region (HRR) level.

Post-discharge events

Data are for 2004 and 2009 and include 30-day readmission rates, emergency room visits within 30 days of discharge, and follow-up visits within 14 days of discharge. More information can be found in After Hospitalization: A Dartmouth Atlas Report on Post-Acute Care for Medicare Beneficiaries.

NOTE: the rates and populations in the HRR and state tables are lower than those in the hospital tables. The regional study includes chronically ill patients who were not hospitalized during the last two years of life, which has the effect of reducing the per capita rates (since these patients were never hospitalized, they had no hospital utilization and lower physician utilization than hospitalized patients). The populations are lower because the regional study used a 20% sample of patients; the 20% Part B database was required to identify chronically ill patients who were not hospitalized.
