Impact of federal antipsychotic use policy in nursing homes on new diagnoses for approved indications in dementia residents

Abstract

AbstractBackgroundFederal policies targeting antipsychotic use among nursing home (NH) residents may have increased reporting of diagnoses for approved uses, including schizophrenia, Tourette's syndrome, and Huntington's Disease (called “exclusionary diagnoses” because they exclude residents from the antipsychotic quality metric). We assessed changes in new exclusionary diagnoses among long‐stay NH admissions specifically with dementia following federal policies.MethodsRetrospective, quarterly, interrupted time‐series analysis (2009–2018) of new long‐stay NH residents with dementia and no exclusionary diagnoses reported before NH admission. The National Partnership and the addition of facility level antipsychotic use to the Five Star Quality Rating system were key time exposures. Outcome was quarterly facility level predicted percentage of exclusionary diagnoses within 2 years of admission stratified by NH characteristics.ResultsFor 264,095 long‐stay admissions, mean percentage of new exclusionary diagnoses was 2.2% before the Partnership. After the Partnership, there was an unadjusted increase in the percentage over time (slope change, 0.044, p = 0.018), but the percentage never exceeded 2.9%. The Partnership contributed to a one‐time decrease in diagnoses in NHs with an intermediate percentage of Black residents (−1.29%, p = 0.004). Before the Partnership, diagnoses were increasing among not‐for‐profit relative to for‐profit NHs (0.044; p = 0.012), but after the Partnership, the pattern reversed. For‐profit NHs saw an increase (+0.034, p = 0.002); not‐for‐profit NHs experienced a decrease (−0.014, p = 0.039). Quality Rating modifications had no significant effect.ConclusionsExclusionary diagnosis reporting among long‐stay NH residents with dementia, the group most at risk from antipsychotics, did not increase in response to federal policies. Evaluation of reasons for the observed increase in exclusionary diagnoses among non‐dementia NH residents is warranted along with continued attention to how to incentivize the appropriate use of medications in residents with dementia that is crucial for high‐quality NH care.
