Identification of barriers, enablers and interventions to inform deimplementation of low-value care in emergency medicine practice: A protocol for a mixed methods scoping review informed by the Theoretical Domains Framework

IntroductionLow-value care can lead to patient harm, misdirected clinician time and wastage of finite healthcare resources. Despite worldwide endeavours, deimplementing low-value care has proved challenging. Multifaceted, context and barrier-specific interventions are essential for successful deimplementation. The aim of this literature review is to summarise the evidence about barriers to, enablers of and interventions for deimplementation of low-value care in emergency medicine practice.Methods and analysisA mixed methods scoping review using the Arksey and O'Malley framework will be conducted. MEDLINE, CINAHL, EMBASE, EMCare, Scopus and grey literature will be searched from inception. Primary studies will be included. Barriers, enablers and interventions will be mapped to the domains of the Theoretical Domains Framework. Study selection, data collection and quality assessment will be performed by two independent reviewers. NVivo software will be used for qualitative data analysis. Mixed Methods Appraisal Tool will be used for quality assessment. Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews framework will be used to present results.Ethics and disseminationEthics approval is not required for this scoping review. This review will generate an evidence summary regarding barriers to, enablers of and interventions for deimplementation of low-value care in emergency medicine practice. This review will facilitate discussions about deimplementation with relevant stakeholders including healthcare providers, consumers and managers. These discussions are expected to inform the design and conduct of planned future projects to identify context-specific barriers and enablers then codesign, implement and evaluate barrier-specific interventions.
