Abstract

Introduction: Research suggests that current care for shoulder pain is not in line with the best available evidence. This project aims to assess the effectiveness, cost-effectiveness and the implementation of an evidence-based guideline for shoulder pain in general practice in Norway.

Methods and analysis: A stepped-wedge, cluster-randomised trial with a hybrid design assessing clinical effectiveness, cost-effectiveness and the effect of the implementation strategy of a guideline-based intervention in general practice. We will recruit at least 36 general practitioners (GPs) and randomise the time of cross-over from treatment as usual to the implemented intervention. The intervention includes an educational outreach visit to the GPs, a computerised decision tool for GPs and a self-management application for patients. We will measure outcomes at patient and GP levels using self-report questionnaires, focus group interviews and register based data. The primary outcome measure is the patient-reported Shoulder Pain and Disability Index measured at 12 weeks. Secondary outcomes include the EuroQol Quality of Life Measure (EQ5D-5L), direct and indirect costs, patient's global perceived effect of treatment outcome, Pain Self-Efficacy and Brief Illness Perception Questionnaire. We will evaluate the implementation process with focus on adherence to guideline treatment. We will do a cost-minimisation analysis based on direct and selected indirect costs and a cost-utility analysis based on EQ5D-5L. We will use mixed effect models to analyse primary and secondary outcomes.

Ethics and dissemination: Ethics approval was granted by the Regional Committee for Medical and Health Research Ethics-South East Norway (ref. no: 2019/104). Trial results will be submitted for publication in a peer-reviewed medical journal in accordance with Consolidated Standards of Reporting Trials.

Trial registration number: NCT04806191.

Timeline. Ten clusters representing each GP surgery. Recruitment of GPs ended in January 2021 and patient inclusion will start during March 2021. All clusters start as a control (blue) and will randomly be allocated to the intervention group (yellow). Implementation will start in June 2021 and will end in June 2022. Each patient is followed for 1 year. GP, general practitioner.
