a The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSI) software requires that the respiratory failure 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, tracheostomy is not verifiable as following surgery. Consistent with the AHRQ PSI software, excludes admissions with respiratory disease, circulatory disease, craniofacial anomalies, or neuromuscular disorders; obstetric admissions; and admissions in which tracheostomy is the only operating room procedure.
b Rates are adjusted by age, gender, age-gender interactions, 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).
