Policy to Reduce Antipsychotic Use and Hospitalization of Nursing Home Residents With Dementia

Abstract

ObjectivesFollowing the 2012 launch of the National Partnership to Improve Dementia Care in Nursing Homes (the National Partnership), the use of antipsychotics has declined. However, little is known about the impact of this effort on quality of care and outcomes for nursing home (NH) residents with Alzheimer's disease and related dementia (ADRD). The objective of this study is to examine changes in hospitalizations for NH long-stay residents with ADRD after the launch of the National Partnership. DesignObservational cross-sectional study. Setting/ParticipantsNH residents who were newly admitted into NHs and became long-stay residents between January 2011 and March 2015 (n = 565,885). MethodsWe estimated linear probability models to explore the relationship between the National Partnership and the likelihood of NH-originated hospitalizations for NH long-stay residents with ADRD, accounting for facility fixed effect, individual covariates, and concurrent changes in hospitalizations among residents without ADRD. We further stratified the analysis by NHs according to their prevalence of antipsychotic use at baseline (ie, prior to the National Partnership). ResultsWe detected a 0.7–percentage point relative increase (P value <.01) in risk-adjusted probabilities of hospitalizations among residents with ADRD compared with non-ADRD residents in the post-Partnership period. In the stratified analysis, we detected a 1.2–percentage point increase (P = .037) in the probability of hospitalizations among ADRD residents in NHs with high antipsychotic use at baseline but no significant change among those in NHs with low antipsychotic use. Conclusions and ImplicationsAlthough the National Partnership may have reduced exposure to antipsychotics, our findings suggest this was related to an increase in hospitalization risk for residents with ADRD. Further research is needed to elucidate the reasons behind the observed relationship and to examine the impact of the National Partnership on other health outcomes.
