Slide Presentation from the AHRQ 2007 Annual Conference

Outcome Measurements
AHRQ Patient Safety Indicators

• Created by AHRQ PSI SAS macro V3.0
  • Each observed rate of patient safety indicator can be defined as "the outcome of interest in the population at risk"
  • The risk-adjusted rate is the rate the provider would have if it had the same case-mix as the reference population (2003 state inpatient datasets from 38 states) given the provider's actual performance.
  • AHRQ recommends suppressing the estimates if fewer than 30 cases are in the denominator
• Only five patient safety indicators are able to provide PSI measures for all rural Iowa hospitals
  • PSI-5: foreign body left during procedure
  • PSI-6: iatrogenic pneumothorax
  • PSI-7: selected infections due to medical care
  • PSI-15: accidental puncture or laceration
  • PSI-16: transfusion reaction
    • Too rare to provide variability to differentiate hospitals in Iowa
