The AHRQ Patient Safety Indicators (PSIs) rely on hospital administrative data to screen for patient safety problems. This study used independent physician chart review to assess the reliability of PSI 11 (postoperative respiratory failure) in identifying clinically significant patient safety events and found a positive predictive value of 38.3%. The authors argue that PSI 11 should not be used as a measure for hospital performance.
