Comments

Rates are adjusted by age, gender, age-gender interactions, comorbidities, and DRG clusters. When reporting is by age, the adjustment is by gender, comorbidities, and DRG clusters; when reporting is by gender, the adjustment is by age, comorbidities, and DRG clusters.

Although not all States participate in the HCUP database, the Nationwide Inpatient Sample 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.
