Comparative Study
Do financial incentives linked to ownership of specialty hospitals affect physicians' practice patterns?
Although physician-owned specialty hospitals have become increasingly prevalent in recent years, little research has examined whether the financial incentives linked to ownership influence physicians' referral rates for services performed at the specialty hospital. ⋯ Physician ownership of specialty hospitals altered the frequency of use for an array of procedures rendered to patients treated at these hospitals. Given the growth in physician-owned specialty hospitals, these findings suggest that health care expenditures will be substantially greater for patients treated at these institutions relative to persons who obtain care from nonself-referral providers.

Recent reports speculate that provider implicit attitudes about race may contribute to racial/ethnic health care disparities. ⋯ Pediatricians held less implicit race bias compared with other MDs and others in society. Among pediatricians we found evidence of a moderate implicit "perceived patient compliance and race" stereotype. Further research is needed to explore whether physician implicit attitudes and stereotypes about race predict quality of care.

The use of health administrative data in health services research is facilitated by standardized classification systems, such as the International Classification of Diseases (ICD). Canada, among other countries, recently introduced the tenth version of ICD and its accompanying Canadian Classification of Interventions (CCI). It is imperative to assess errors that could occur in administrative data due to the introduction of the new coding system. ⋯ Both ICD-9-CM and CCI coded the more major or invasive procedures reasonably well, but were not valid for less invasive or minor procedures. CCI can be used by health services and population health researchers with as much confidence as ICD-9-CM.

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.
