a The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSI) software requires that the hemorrhage or hematoma complicating procedure be reported as a secondary diagnosis (rather than the principal diagnosis), but unlike the AHRQ PSI software, the secondary diagnosis could be present on admission. In addition, the control of the hemorrhage or hematoma is not verifiable as following surgery. Consistent with the AHRQ PSI software, obstetric conditions and admissions in which the control of the hemorrhage or hematoma is the only operating room procedure are excluded.

b Rates are adjusted by gender, comorbidities, major diagnostic category (MDC), diagnosis-related group (DRG), and transfers into the hospital. The AHRQ PSI software was modified to not use the present on admission (POA) indicators (or estimates of the likelihood of POA for secondary diagnosis).

Key: SE: standard error.
