^a. The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSI) software requires that the iatrogenic pneumothorax 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. Consistent with the AHRQ PSI software, the following cases are excluded: obstetric admissions and admissions with chest trauma, pleural effusion, thoracic surgery, lung/pleural biopsy, diaphragmatic surgery repair, and cardiac surgery.

^b. Rates are adjusted by age, gender, age-gender interactions, comorbidities, major diagnostic category (MDC), and 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).

Key: SE: standard error.
