Objectives The South Peace Polypharmacy Reduction Project is a quality improvement project in three communities in rural Canada that aimed to reduce polypharmacy and inappropriate prescribing practices in older adults. This study aims to evaluate the impact of a multifaceted intervention consisting of online team-based medication reviews and educational workshops on the number of chronic medications. Methods A controlled before-after design was used to compare if a decrease in the number of chronic medications was associated with the intervention comprising of online team-based medication reviews and educational workshops, compared with two matched control groups that received either a standard medication review or no medication review. Logistic regression models fit with generalized estimated equations were used to identify the impact of the interventions on decreasing the number of chronic medications. Key findings Following a medication review, the percentage of individuals that had deprescribed at least one medication was highest in the intervention group (52%), followed by the medication review controls at 45%, and 36% in non-medication review controls. Individuals in the intervention group were 20% more likely to have at least one medication deprescribed than individuals in the medication review control group (adjusted odds ratio: 1.20; 95% CI: 1.03 to 1.39), whereas they were 42% more likely to deprescribe at least one medication compared with non-medication review controls (adjusted odds ratio: 1.42; 95% CI: 1.25 to 1.61). Conclusions Online team-based medication reviews had a significant impact on decreasing the number of chronic medications in older adults. Furthermore, providing healthcare providers with education can complement the role of other healthcare interventions. [ABSTRACT FROM AUTHOR]
