Knowledge, practice and attitudes regarding substance use disorder treatment and harm reduction strategies among...

Pharmacists provide a spectrum of services and comprehensive medication management for patients with substance use disorders (SUDs) with many providing timely and increased access to care for patients. Prior studies have evaluated other healthcare professionals' attitudes, knowledge and practice in regard to SUD treatment and harm reduction services. However, no reviews to date summarise the available literature on the attitudes, knowledge and practice in regard to SUD treatment and harm reduction services from the pharmacist perspective. This scoping review aims to systematically map the extent, range and nature of available evidence and identify and describe gaps in knowledge, practice and attitudes towards SUD treatment among pharmacists with the goal of providing information for meaningful integration of pharmacists into SUD care.

We will use the framework proposed by Arksey and O'Malley (2005) updated with recommendations by Levac et al (2010) and the Joanna Briggs Institute (2020). The protocol is registered via Open Science Framework (https://osf.io/92dek). We will search for peer-reviewed literature containing empirical evidence investigating SUD treatment or harm reduction with outcomes pertaining to the knowledge, practice or attitudes of pharmacists. Findings will be guided and assessed by research objectives and summarised using descriptive statistics and thematically for quantitative and qualitative findings, respectively. This review will be conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews.

Our findings will provide crucial information and support for future interventions and programmes which aim to meaningfully integrate pharmacists into SUD care. We will disseminate findings at conferences and publish in a peer-reviewed journal. In addition, we will integrate feedback on search strategy, data extraction and our dissemination approach from multidisciplinary collaborators including those within our team's institution and outside experts with clinical or administrative knowledge in SUD care.
