Abstract

Introduction and Objective

As the population ages, understanding the potential risks associated with inappropriate medication use becomes increasingly important. Given the lack of studies in this area, our objective was to study the risk of mortality associated with potentially inappropriate medication use involving opioids in community-dwelling older adults.

Methods

Data came from a longitudinal study on older adults aged ≥ 65 years recruited in primary care clinics between 2011 and 2013 with an average follow-up of 4.25 years. Older adults were excluded if they used an opioid or had a malignant tumor diagnosis in the year before the study survey. A nested case-control within a cohort of older adults with at least one opioid claim during follow-up was used to evaluate the risk of all-cause mortality. Four controls per case were matched on follow-up time using risk-set sampling, i.e., while still at risk of death when their matched case died. The risk of mortality was estimated using conditional logistic regression analyses. Exposure to potentially inappropriate medication use involving opioids, defined using the Beers 2019 criteria, was assessed from provincial drug claims data in the 0–90 days before death.

Results

In a cohort of 472 community-dwelling older adults with an incident episode of opioid use, there were 40 cases matched to 160 controls. Exposure to inappropriate medication use involving opioids in the 90 days before death was associated with an increased risk of mortality (odds ratio 6.81, 95% confidence interval 1.69–27.47), after adjusting for potential confounders.

Conclusions

Exposure to inappropriate medication use involving opioids in the 90 days before death is associated with an increased risk of mortality in older adults. These findings can be used to encourage safer pain management strategies in older adults.
