A Scoping Review of Outpatient Interventions to Support the Reduction of Prescription Opioid Medication for Chronic Non Cancer Pain

Background: Prescription opioid use is a global health issue. Previous systematic reviews have not identified that any specific intervention supports prescription opioid reduction effectively. In keeping with the nature of a scoping review, this review details an overview of the existing literature on this topic, with quality of evidence being discussed rather than formally analysed.

Aim: This review aimed to examine and describe outpatient interventions that support the reduction of prescription opioid medication for chronic non cancer pain.

Eligibility Criteria: Abstracts were reviewed against the inclusion criteria of outpatient clinical interventions, for the purpose of prescription opioid dose reduction, offered to adults with CNCP.

Sources Of Evidence: Following a structured review approach an electronic database search, of Medline, Embase, Cochrane, Cinahl, and Proquest and grey literature was undertaken. Search results were screened by title for relevance.

Charting Methods: Two reviewers adhering to the PRISMA-ScR checklist charted and assessed studies for quality using Critical Appraisal Skills Programme checklist assessment tools. Extracted data were collated and synthesised for presentation as a tabular and narrative review.

Results: From the initial search of 5089 papers, 19 underwent full-text review and quality appraisal. A variety of interventions were described to support reduction in prescription opioid use, however only one study of at least fair quality was able to demonstrate a demonstrated a statistically significant benefit in reducing measured opioid dose compared with a control group. Interventions were implemented in both specialist pain services and in primary care with multidisciplinary and interdisciplinary clinician care. Barriers and facilitators were observed in both settings.

Conclusion And Implications For Clinical Practice: Further rigorous research needs to be conducted to conclusively answer the question of what outpatient interventions support opioid reduction in chronic non cancer pain. This scoping review is the first step of inquiry in the development of a nursing intervention to support reduction of prescription opioids.
