a. Complications of care include acute renal failure, pneumonia, pulmonary embolism, deep vein thrombosis, sepsis, shock, cardiac arrest, gastroentestinal hemorrhage, and acute ulcers.� Transfers from another hospital are excluded.� The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (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 (MDC), diagnosis-related roup (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).
