Optimizing Practices, Use, Care, and Services-Antipsychotics (OPUS-AP) in Long-Term Care Centers in Quebec, Canada: A Successful Scale-Up

Abstract

Objectives: To evaluate the scale-up of the OPUS-AP program to improve the care of residents at long-term care (LTC) centers through the systematic implementation of resident-centered approaches to care, the application of nonpharmacologic interventions for the management of behavioral and psychological symptoms of dementia (BPSD), and the deprescribing of antipsychotics where these are not clinically indicated.

Design: Prospective, closed cohort.

Setting and participants: Residents with major neurocognitive disorder (MNCD) from 24 (phase 1) and 129 (phase 2) publicly funded LTC centers in Quebec, Canada.

Methods: The primary outcome was antipsychotic deprescribing (cessation or dose reduction). Secondary outcomes included changes in benzodiazepine and antidepressant prescriptions, BPSD, and falls. Comparisons were made between assessments at baseline and after 9 months.

Results: OPUS-AP phase 2 was conducted from March to December 2019 in 329 clinical wards at 129 LTC centers. At baseline, the 10,601 included residents had a mean age of 82.9: 64.6% were of female sex, 73.7% had a diagnosis of MNCD, and 47.0% had an antipsychotic prescription. These characteristics were similar to those of the 1054 residents at the 24 LTC centers in phase 1. In phase 2, successful antipsychotic deprescribing was achieved for 77.1% of residents in whom this approach was attempted, compared to 85.5% in phase 1. Phase 1 and 2 showed statistically significant improvements in the Cohen-Mansfield Agitation Inventory score and reduced use of benzodiazepines in residents with successful antipsychotic deprescribing. These improvements were of a smaller magnitude in phase 2. Statistically significant reductions in falls were observed in phase 2.

Conclusions and implications: The scale-up of the OPUS-AP program from 24 to 129 LTC centers was successful and resulted in a significant reduction in antipsychotic use, as well as improvement in BPSD, and reductions in benzodiazepine use and falls in residents with successful antipsychotic deprescribing.
