a Consistent with the Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSI) software, complications of care include acute renal failure, pneumonia, pulmonary embolism, deep vein thrombosis, sepsis, shock, cardiac arrest, gastroentestinal hemorrhage, and acute ulcer. Transfers to another hospital are excluded. The AHRQ PSI software requires that the complication 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 surgery is not verifiable as occurring in the first 2 days of the inpatient stay.
b Rates are adjusted by age, comorbidities, major diagnostic category, diagnosis-related group, 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).
