a The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSI) software requires that the physiologic and metabolic derangements 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 derangement is not verifiable as following surgery. Consistent with the AHRQ PSI software, excludes obstetric admissions and admissions for ketoacidosis, hyperosmolarity, diabetic coma, acute renal failure, chronic renal failure, acute myocardial infarction, cardiac arrhythmia, cardiac arrest, shock, hemorrhage, and gastrointestinal hemorrhage.

b Rates are adjusted by age, gender, age-gender interactions, comorbidities, major diagnostic category (MDC), diagnosis-related group (DRG). When reporting is by age, the adjustment is by gender, comorbidities, MDC, and DRG; when reporting is by gender, the adjustment is by age, comorbidities, MDC, and DRG. 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).

DSU - Data do not meet the criteria for statistical reliability, data quality, or confidentiality.

Key: SE: standard error.
