: Abbreviations: DRG, diagnosis related group; PSI, Patient Safety Indicator
: Notes: The unit of observation is the hospital. Hospitals were included in the analysis for an individual PSI if there were at least 10 at-risk denominator cases in that PSI in a given year. PSIs are reported as the number of adverse patient safety events per 1,000 discharges at risk. The hospital PSI rates are risk adjusted for age, sex, age-sex interaction, major diagnostic categories, modified DRGs, and comorbidities. Some rates are risk adjusted for transfers from another facility or severity of complications present on admission. Data include discharges billed to all expected payers (Medicare, Medicaid, private insurance, no insurance, and other).
a: Depending on the indicator, the number of cases at risk (denominator) is based on discharges for low mortality DRGs (PSI 02), medical and surgical discharges (PSI 03, PSI 06, PSI 07, PSI 08), elective surgical discharges (PSI 04, PSI 11, PSI 13), surgical discharges (PSI 09, PSI 10, PSI 12), or abdominopelvic surgical discharges (PSI 14, PSI 15).
b: Included in the calculation of the Patient Safety and Adverse Events Composite (PSI 90)
