Longitudinal Evaluation of a Deprescribing Protocol in Skilled Nursing Facilities

Abstract

Objective: To determine whether a deprescribing effort reduced several key classes of medications, and the overall number of medication classes per patient, among long-term residents of skilled nursing facilities (SNFs). Design: Retrospective, longitudinal pre/post evaluation. Data from before and during the implementation of the deprescribing effort (2017 through 2019) were compared with data from the post-intervention year (2020). Setting and Patients: Long-term resident data reported through annual comprehensive reviews conducted at two SNFs located in central New York State between 2017 and 2020 (N = 12,144). Interventions: Multifaceted, interdisciplinary deprescribing effort to reduce medications in SNF residence including clinician education, guideline development, and individual chart reviews began in 2019. Results: The mean number of medications prescribed per resident was lower at both facilities after the intervention (mean = 1.74 at both facilities) versus preintervention (1.90 at Facility 1, 1.86 at Facility 2). Significant decreases were observed in the usage rates for diuretics (-4.2%; P = 0.001), opioids (-3.8%; P = 0.001), and antipsychotics (-2.4%; P = 0.010). The raw antidepressant usage rate increased by 1.5% after the intervention but the change was not significant. Effects were robust to covariate adjustment. Conclusion: A combined, comprehensive approach to deprescribing was associated with a reduction in the overall number of medication classes per resident and in several key classes of medications. Additional research with more data and covariate control is in progress for verification of these findings.
