^a. The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSI) software requires that the pressure ulcer 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: transfers from other institutions; admissions from long-term care facilities; admissions with diseases of the skin, subcutaneous tissue, or breast; admissions for hemiplegia, paraplegia, quadriplegia, spina bifida, or anoxic brain damage; and admissions in which debridement or pedicle graft is the only operating room procedure.

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