Evaluating an inpatient deprescribing initiative at a rural community hospital in Ontario.

BACKGROUND

Deprescribing is an effective means to reduce polypharmacy in elderly patients. However, geriatric day care deprescribing services are challenging to implement in rural regions. In this study, we examined whether a subacute care unit of a rural hospital could deliver a comprehensive and multidisciplinary intervention to promote deprescribing in patients and whether this intervention would succeed in achieving significant and lasting deprescribing results.

METHODS

We conducted a cross-sectional analysis of a deprescribing program at a rural hospital in Eastern Ontario, Canada. Participants were 11 patients, aged 65 or older, who were admitted to the hospital's medical/surgical unit or who presented to the emergency department. Clinicians followed a structured, comprehensive and multidisciplinary approach designed to facilitate deprescribing, which concluded with an outcome evaluation at discharge and follow-up phone calls. Outcomes included the frequency and total number of medications successfully removed, reduced, substituted and restarted after discharge and emergency department visits and hospitalizations 6 months before and after the intervention.

RESULTS

Of a total 57 deprescribed medications, 38 were eliminated, 8 were switched to a safer alternative, and 11 were dose reduced. Postdischarge deprescribing reversal occurred in only 5 of 57 deprescribed medications. Among the study population, a 59.2% reduction was observed in the combined number of emergency department visits and hospitalizations 6 months after deprescribing.

CONCLUSIONS

This feasibility study was successful in showing the potential added value for offering a rehabilitative, subacute care, inpatient, comprehensive and multidisciplinary approach toward patients with complex deprescribing needs. It also showed proof of concept in reducing polypharmacy-induced adverse health outcomes. 2020:153:xx-xx.
