Thomas KS, Wretman CJ, Sloane PD, Carder P, Schwartz L, Beeber AS, Zimmerman S. To What Extent Do Local Nursing Home Prescribing Patterns Relate to Psychotropic Prescribing in Assisted Living? Journal of The American Medical Directors Association. 2021 Sep 1; 22(9):1813-1818.e3.
Dimensions for VA is a web-based tool available to VA staff that enables detailed searches of published research and research projects. OBJECTIVE: In nursing homes (NHs), psychoactive medication use has received notable attention, but less is known about prescribing in assisted living (AL). This study examined how antipsychotic and antianxiety medication prescribing in AL compares with NHs. DESIGN: Observational, cross-sectional AL data linked to publicly reported NH measures. SETTING AND PARTICIPANTS: Random sample of 250 AL communities and the full sample of 3371 NHs in 7 states. METHODS: We calculated the percentage of residents receiving antipsychotics and antianxiety medications. For each AL community, we calculated the distance to NHs in the state. Linear models estimated the relationship between AL prescribing and that of the closest and farthest 5 NHs, adjusting for AL characteristics and state fixed effects. RESULTS: The prescribing rate of potentially inappropriate antipsychotics (i.e., excluding for persons with recorded schizophrenia and Tourette syndrome) and of antianxiety medications (excluding for those on hospice) in AL was 15% and 21%, respectively. Unadjusted mean antipsychotic prescribing rates were nominally higher in AL than NHs (14.8% vs 14.6%; P = .056), whereas mean antianxiety prescribing was nominally lower in AL (21.2% vs 22.6%; P = .032). In adjusted analyses, AL rates of antipsychotic use were not associated with NH rates. However, being affiliated with an NH was associated with a lower rate of antipsychotic use [b = -0.03; 95% confidence interval (CI) -0.50 to -0.001; P = .043], whereas antianxiety rates were associated with neighboring NHs'' prescribing rates (b = 0.43; 95% CI 0.16-0.70; P = .002). CONCLUSIONS AND IMPLICATIONS: This study suggests reducing antipsychotic medication use in NHs may influence AL practices in a way not accounted for by local NH patterns. And, because antianxiety medications have not been the focus of national campaigns, they may be more subject to local prescribing behaviors. It seems advantageous to consider prescribing in AL when efforts are implemented to change NH prescribing, as there seems to be related influence whether by affiliation or region.
