Comments

Rates are adjusted by age, gender, age-gender interactions, comorbidities, and DRG clusters. DRGs are Diagnosis Related Groups which identify patients with similar illnesses.

Although not all states participate in the HCUP database, it is weighted to give national estimates using weights based on all U.S. community, non-rehabilitation hospitals in the American Hospital Association Annual Survey of Hospitals.

These tables were created using a beta-test version of the AHRQ Patient Safety Indicators software dated July 2002 that differs from the AHRQ Patient Safety Indicators software currently available on the AHRQ Web site. These measures are referred to as indicator 6 (discharge-based) and 22 (area-based) in the AHRQ Patient Safety Indicators software documentation.
