Abstract
ObjectivesTo examine the prevalence of mental health treatment among nursing home (NH) long-stay residents with Alzheimer's disease and related dementias (ADRD) and explore factors associated with utilization. DesignRetrospective cohort study. Minimum Data Set data (April 2017–September 2018), Medicare Master Beneficiary Summary File, Part B Carrier file and Part D prescription file were used to identify mental illness and ADRD diagnoses, patient characteristics, and mental health treatment. Setting and ParticipantsAll US Medicare- or Medicaid-certified NHs. Fee-for-service Medicare beneficiaries aged 65 and older who had a quarterly or annual Minimum Data Set assessment with ADRD and were enrolled in Medicare Parts B and D. Two cohorts: residents with both ADRD and psychiatric disorders; residents with ADRD only. MethodsPrimary outcomes: receipt of (1) any mental health treatment (medication or psychotherapy); (2) any psychotherapy in a calendar quarter. Secondary outcomes: antipsychotics, antidepressants, hypnotics, antiepileptics, short-session ( ≤ 30 minutes), long-session ( ≥ 45 minutes), and family/group psychotherapy. Covariates included predisposing, enabling characteristics, and needs factors. Generalized Estimating Equation models of quarterly data, nested within patients, were estimated for each outcome among each cohort. ResultsAnalyses included 1,913,945 resident-quarter observations from 503,077 unique NH long-stay residents. Overall, 68.5% of NH long-stay residents with ADRD have psychiatric disorders; of these, 85% received mental health treatment. African American or Hispanic residents were less likely to use antidepressants. African American residents or residents living in rural locations were less likely to receive long-session psychotherapy. Hispanic residents were more likely to receive long-session psychotherapy. Residents in minority groups were more likely to receive group/family psychotherapy. Conclusions and ImplicationsMost of NH long-stay residents with ADRD had psychiatric disorders and most of them received treatment. Antidepressants or long-session psychotherapy were less likely to be provided to African American residents. Factors that determine the efficacy of mental health treatment and reasons for the racial disparities require further exploration.
