The Agency for Healthcare Research and Quality (AHRQ) developed 20 patient safety indicators (PSIs) to identify potentially preventable complications of acute inpatient care based on administrative data. The objective of this patient safety performance study was to assess the impact of cases flagged by each PSI for diagnoses that were actually present on admission on unadjusted PSI rates. ⋯ Unadjusted PSI rates at UMHS are substantially overstated, because the PSIs do not differentiate preexisting conditions from complications and therefore include false positive cases. Because of these findings and the lack of a broader study of the validity of the indicators, PSIs should not be used to profile hospital performance.

The Centers for Medicare and Medicaid Services (CMS) publish a report card for nursing homes with 19 clinical quality measures (QMs). These measures include minimal risk adjustment. ⋯ More extensive risk adjustment changes quality ranking of nursing homes and should be considered as potential improvement to the current QMs. Other methodological issues related to construction of the QMs should also be investigated to determine if they are important in the context of nursing home care.

There has been widespread concern that procedurally oriented specialty hospitals select well-insured patients for admission, while avoiding the underinsured, but data are limited. ⋯ Patients with more generous insurance are significantly more likely to gain admission to specialty hospitals. Alternatively, we found no evidence that specialty hospitals preferentially transfer patients with less generous insurance who are admitted. Overall, these findings suggest that specialty hospitals may contribute to segregation of the healthcare system along socioeconomic lines.
