Deprescribing practices in Canada: A scoping review

Background: Excessive and inappropriate use of medications, defined as polypharmacy, can increase the risk of adverse drug reactions while affecting patient adherence and quality of life. Therefore, optimizing pharmacotherapies through deprescribing practices plays a crucial role in managing chronic conditions, avoiding adverse effects and improving patient outcomes. The purpose of this study was to explore research initiatives surrounding deprescribing in Canada. Methods: A scoping review was conducted that involved a search of 6 databases. Studies that highlighted deprescribing interventions, experiences and other effects on Canadian populations were included. Results: Searches yielded 2327 citations, of which 31 were included in this review. Five major themes and ideas were identified: deprescribing targeted medications, financial effects of deprescribing, deprescribing in special populations, insight from health care providers and deprescribing frameworks. Conclusion: Deprescribing practices in Canada have shown a wide range of beneficial results across various health care settings, populations and medication classes and have the potential to reduce medication related harm in all Canadian health care settings.
