Abstract
Background and Objectives
Residents of long-term care (LTC) homes in Ontario, Canada are older, frailer, and have more complex care needs than their community dwelling counterparts. In addition, they often have multiple comorbidities and potentially painful conditions. As a result, they are often prescribed opioids, which may result in medication-related patient safety events. Opioid deprescribing may be a strategy for mitigating adverse events. Therefore, the purpose of this study was to examine opioid deprescribing among residents of LTC homes in Ontario.
Methods
We conducted a population-based retrospective cohort study using the routinely collected health administrative databases held at ICES (formerly the Institute for Clinical Evaluative Sciences). The cohort consisted of residents of LTC homes in Ontario prescribed long-term opioid therapy (a continuous prescription for an opioid for 90 days or longer) between April 1, 2014, and March 31, 2016. We allowed a two-year look back window to collect data about baseline characteristics for residents, and a two-year follow-up period to examine outcomes. We used a three-level exposure variable: (1) no discontinuation, (2) discontinuation for 30-119 days, and (3) discontinuation for 120 days or longer. Outcomes included unplanned acute healthcare use, all-cause mortality, and functional measures. Multivariate modeling was used to determine the associations between opioid deprescribing and outcomes.
Results
There were 26,592 residents prescribed long-term opioid therapy between April 1, 2014, and March 31, 2016, and 4,299 (16.2%) had opioids discontinued during the follow-up period: 2,852 (66.3%) short term, and 1,447 (33.7%) long-term. Short term opioid deprescribing was associated with a 13% reduced risk for death, and short and long-term opioid deprescribing were associated with an increased risk for unplanned acute healthcare use.
Conclusions
Over 20% of residents were prescribed long-term opioid therapy, and opioid deprescribing was sustained in very few residents. Healthcare providers must be informed about the adverse outcomes associated with opioid deprescribing and long-term opioid therapy to support resident needs and preferences related to the interprofessional plan of care. Findings from this study will be used to inform safe, quality, resident-centered care, direct future research, inform the development of opioid deprescribing guidelines, and inform health policy.
