RESUMO
OBJECTIVES: Antipsychotic medications are often used for the first-line management of behavioral and psychological symptoms of dementia (BPSD) contrary to guideline recommendations. The Optimizing Practices, Use, Care and Services-Antipsychotics (OPUS-AP) strategy aims to improve the well-being of long-term care (LTC) residents with major neurocognitive disorder (MNCD) by implementing a resident-centered approach, nonpharmacologic interventions, and antipsychotic deprescribing in inappropriate indications. DESIGN: Prospective, closed cohort supplemented by a developmental evaluation. SETTING AND PARTICIPANTS: Residents of designated wards in 24 LTC centers in Québec, Canada. METHODS: Provincial guidelines were disseminated, followed by the implementation of an integrated knowledge translation and mobilization strategy, including training, coaching, clinical tools, evaluation of clinical practices, and a change management strategy. Antipsychotic, benzodiazepine, and antidepressant prescriptions; BPSD; and falls were evaluated every 3 months, for 9 months, from January to October 2018. Semistructured interviews (n = 20) were conducted with LTC teams to evaluate the implementation of OPUS-AP. RESULTS: Of 1054 residents, 78.3% had an MNCD diagnosis and 51.7% an antipsychotic prescription. The cohort included 464 residents with both MNCD and antipsychotic prescription. Antipsychotic deprescribing (cessation or dose decrease) was attempted in 220 of the 344 residents still admitted at 9 months. Complete cessation was observed in 116 of these residents (52.7%) and dose reduction in 72 (32.7%), for a total of 188 residents (85.5%; 95% confidence interval: 80.1%, 89.8%). A decrease in benzodiazepine prescriptions and improvements in Cohen-Mansfield Agitation Inventory scores were observed among residents who had their antipsychotics deprescribed. Caregivers and clinicians expressed satisfaction as a result of observing an improved quality of life among residents. CONCLUSIONS AND IMPLICATIONS: Antipsychotic deprescribing was successful in a vast majority of LTC residents with MNCD without worsening of BPSD. Based on this success, phase 2 of OPUS-AP is now under way in 129 LTC centers in Québec.
