The Role of Severe Dementia in Nursing Home Report Cards.

Health care report cards are intended to improve quality, but there may be considerable heterogeneity in who benefits. In this article, we examine the intended and unintended effects of quality reporting for nursing home residents with severe dementia relative to other residents, using a difference-in-differences design to examine selected reported and unreported quality measures. Our results indicate that prior to public reporting, nursing home residents with severe dementia were at significantly higher risk of poor outcomes on most reported quality measures. After public reporting was initiated, outcomes for nursing home residents with severe dementia did not consistently improve or worsen. We see no evidence that individuals with severe dementia are being avoided by nursing homes, despite their potential negative impact on quality scores, but we do find an increase in coding of end-stage disease. Additional risk-adjustment, stratification, or additional quality measures may be warranted.
