Patient engagement, treatment preferences and shared decision-making in the treatment of opioid use disorder in adults: a scoping review protocol

Introduction

Opioid use disorder (OUD) is characterised by the fifth Edition of the Diagnostic and Statistics Manual as a problematic pattern of opioid use (eg, fentanyl, heroin, oxycodone) that leads to clinically significant impairment. OUD diagnoses have risen substantially over the last decade, and treatment services have struggled to meet the demand. Evidence suggests when patients with chronic illnesses are matched with their treatment preferences and engaged in shared decision-making (SDM), health outcomes may improve. However, it is not known whether SDM could impact outcomes in specific substance use disorders such as OUD.

Methods and analysis

A scoping review will be conducted according to Arksey and O'Malley's framework and by recommendations from Levac et al. The search strategy was developed to retrieve relevant publications from database inception and June 2017. MEDLINE, EMBASE, PsycINFO, Cochrane Database for Controlled Trials, Cochrane Database for Systematic Reviews and reference lists of relevant articles and Google Scholar will be searched. Included studies must be composed of adults with a diagnosis of OUD, and investigate SDM or its constituent components. Experimental, quasi-experimental, qualitative, case–control, cohort studies and cross-sectional surveys will be included. Articles will be screened for final eligibility according to title and abstract, and then by full text. Two independent reviewers will screen excluded articles at each stage. A consultation phase with expert clinicians and policy-makers will be added to set the scope of the work, refine research questions, review the search strategy and identify additional relevant literature. Results will summarise whether SDM impacts health and patient-centred outcomes in OUD.

Ethics and dissemination

Scoping review methodology is considered secondary analysis and does not require ethics approval. The final review will be submitted to a peer-reviewed journal, disseminated at relevant academic conferences and will be shared with policy-makers, patients and clinicians.
