Psychotherapy and Problematic Behavior Reduction in Long-Stay Nursing Home Residents With Alzheimer's Disease and Related Dementias.

OBJECTIVES

To examine the association between receipt of psychotherapy and behavior reduction among long-stay nursing home residents with Alzheimer's disease and related dementias (ADRD).

DESIGN

Retrospective cohort study using Minimum Data Set assessments linked to Medicare: Master Beneficiary Summary File, Part B Carrier, and Part D Event file (2017-2018).

SETTING AND

PARTICIPANTS

All US Medicare- or Medicaid-certified nursing homes. Traditional Medicare beneficiaries enrolled in Medicare Parts B and D, aged ≥65 with ADRD and any problematic behaviors (physical, verbal, or other), stratified to residents with both ADRD and co-occurring psychiatric disorders, and ADRD only.

METHODS

The unit of analysis was 2 consecutive quarters with indication of a problematic behavior in the first. Outcomes were reductions in any, physical, verbal, or other behaviors. The treatment was receipt of psychotherapy in both quarters vs neither. Covariates included predisposing, enabling, and need factors. Propensity score weighting balanced resident characteristics, and generalized estimating equation logistic models were applied.

RESULTS

The cohort included 175,165 resident-quarter observations from 99,584 unique long-stay residents with ADRD and problematic behaviors. Psychotherapy was received in 9% of observations, most often in short (73%), quarterly (59%), or monthly (35%) sessions delivered by psychologists (56%) or social workers (34%). After weighting, psychotherapy was associated with greater likelihood of behavior reduction (ADRD + psychiatric disorders: 17%, P < .01; ADRD only: 33%, P < .05). In ADRD-only residents, psychotherapy was associated with 36% reduction in physical behaviors and 28% in verbal behaviors. In those with ADRD + psychiatric disorders, reductions were seen in physical (31%) and other behaviors (18%).

CONCLUSIONS AND IMPLICATIONS: Fewer than 10% of nursing home residents with ADRD and problematic behaviors received psychotherapy, yet its receipt was significantly associated with behavior reduction. Findings underscore the need to expand access to psychotherapy in nursing homes and to further investigate the psychotherapy characteristics that contribute to effectiveness.
