Implementability of opioid deprescribing interventions at transitions of care: A scoping review.

Continuation of opioids at transitions of care increases the risk of long-term opioid use and related harm. To our knowledge, no study has examined the implementability of opioid deprescribing interventions at transitions of care. Our scoping review aimed to identify the type of opioid deprescribing interventions employed at transitions of care and assess the implementability of tested interventions. Nine electronic databases were searched on 15 May 2023 for English-language studies of adults transitioning between care settings, where opioid deprescribing interventions targeting patients, clinicians or health systems were implemented. Implementability was assessed using the Cochrane Intervention Complexity Assessment Tool for Systematic Reviews to determine intervention complexity, and mapped to the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework to understand the process evaluation. A total of 79 studies were identified, with 94.0% (n = 74) examining hospital-to-home transitions. Mixed interventions (combination of pharmacological and nonpharmacological) were tested in 49.0% (n = 39) of studies. Pharmacological interventions were identified in 31.0% (n = 24) of studies, and the remaining 20.0% (n = 16) applied nonpharmacological interventions. Mixed interventions comprising multiple components were the most complex and resulted in reduced opioid use across transitions of care in 28.0% (n = 22) of studies. Few studies reported on RE-AIM dimensions including implementation (5.0% of studies), reach (4.0%), adoption (4.0%) and maintenance (0%). Most opioid deprescribing interventions targeted hospital to home care transition with mixed results in opioid deprescribing. Further research should consider the implementability of interventions during transitions of care to elucidate the impact of opioid deprescribing interventions across care settings.
