RECREATE: a study protocol for a multicentre pilot cluster randomised controlled trial (cRCT) in UK stroke services evaluating an intervention to reduce sedentary behaviour in stroke survivors (Get Set Go) with embedded process and economic evaluations.

INTRODUCTION

Sedentary behaviour (sitting or lying during waking hours without being otherwise active) is strongly associated with adverse health outcomes, including all-cause, cancer and cardiovascular mortality in adults. Stroke survivors are consistently reported as being more sedentary than healthy age-matched controls, spending more hours sedentary daily and sustaining longer unbroken bouts of sedentary time. An evidence-based and clinically feasible intervention ('Get Set Go') was developed. A pragmatic definitive trial to evaluate Get Set Go was planned; however, due to the unprecedented effects of the COVID-19 pandemic on National Health Service (NHS) services this study was reduced in size and scope to become an external pilot trial. We report the protocol for this external pilot trial, which aims to undertake a preliminary exploration of whether Get Set Go is likely to improve ability to complete extended activities of daily living in the first year post-stroke and inform future trial designs in stroke rehabilitation.

METHODS AND ANALYSIS

This study is a pragmatic, multicentre, two-arm, external pilot cluster randomised controlled trial with embedded process and economic evaluations. UK-based stroke services will be randomised 1:1 to the intervention (usual care plus Get Set Go) or control (usual care) arm. Fifteen stroke services will recruit 300-400 stroke inpatient and carer participants, with follow-up at 6, 12 and 24 months. The proposed primary endpoint is stroke survivor self-reported Nottingham Extended Activities of Daily Living scale at 12 months. Endpoint analyses will be exploratory and provide preliminary estimates of intervention effect. The process evaluation will provide valuable information on intervention fidelity, acceptability and how it can be optimised.

ETHICS AND DISSEMINATION

The study has been approved by Yorkshire and The Humber - Bradford-Leeds Research Ethics Committee (Ref: 19/YH/0403). Results will be disseminated through journal publications and conference presentations.
