Effectiveness of personal letters to healthcare professionals in changing clinical practice behaviours: A Systematic Review protocol
Abstract Background: Letters are regularly sent by healthcare organisations to healthcare professionals to encourage them to take action, change practice or implement guidance. However, whether letters are an effective tool in delivering a change in clinical practice behaviour is currently uncertain. In addition, there are currently no evidence-based guidelines to support providers and health authorities with advice on how to formulate the communication, what information and behaviour change techniques to include in order to optimise the potential effect on the behaviour of the receivers. To address this research gap, we aim to inform such guidance through this systematic review.Methods/ Design: A systematic literature search of published and unpublished studies (the grey literature) in electronic databases will be conducted to identify studies that meet our inclusion criteria. The search will be conducted in five electronic databases: MEDLINE, EMBASE, PsycINFO, the Cochrane Library and CINAHL. We will also conduct supplementary searches in Google Scholar, hand search relevant journals, and conduct backward and forward citation searching for included studies and relevant reviews. A systematic approach to searching, screening, reviewing and data extraction will be applied based on Preferred Reporting Items for Systematic reviews and Meta-Analysis. Titles, abstracts, full-texts for eligibility will be examined independently by researchers. The quality of the included studies will be assessed using quality assessment tool for studies with diverse design and Cochrane risk of bias tool. Disagreements will be resolved by a consensus procedure.Discussion: This review aims to provide comprehensive evidence of the effectiveness of personal letters to healthcare professionals in changing clinical practice behaviours. Health policy makers across government will benefit from being able to increase compliance in clinical settings by applying theories of behaviour to design of policy communications. The synthesized findings will be disseminated through peer-reviewed publication.Systematic review registration: PROSPERO CRD42020167674
