Swallowing prehabilitation for people with head and neck cancer: a pilot cluster-randomised feasibility trial of the SIP SMART intervention.

Abstract

To assess the feasibility of delivering the swallowing prehabilitation intervention known as Swallowing Intervention Package: Self-Monitoring, Assessment and Rehabilitation Training (SIP SMART) within the National Health Service (NHS) head and neck cancer care pathway. Two-arm cluster-randomised pilot trial: SIP SMART2 trial. Adults newly diagnosed with stage II-IV head and neck cancer receiving curative treatment within a multidisciplinary team who agree to participate. Six hospitals were randomised. Trained clinicians at the intervention sites delivered the manualised SIP SMART intervention, while standard care was provided at care as usual (CAU) sites. The intervention included two 45-minute consultations incorporating an X-ray swallow assessment, tailored exercises/advice and specific behaviour change strategies while CAU involved a single consultation of information giving and provision of a generic exercise sheet. Study outcomes related to feasibility of the cluster-randomised design, recruitment of both sites and patients and completeness of clinical and health economic data collected at baseline, 4 weeks, 12 weeks and 24 weeks after treatment. 12 hospitals expressed interest and six were randomised (50%) and provided data to the point of study completion. Patient recruitment across all sites (n=76) reached the target, although two sites fell short of their individual targets. The proportion of people with HNC recruited versus those eligible for each arm was 39% (95% CI 29 to 49) for SIP SMART group and 55% (95% CI 43 to 66) for CAU. The end point data at 24 weeks were completed for 50% (95% CI 33 to 67) for SIP SMART and 78% (95% CI 62 to 89) for CAU. Adherence to the intervention was above 50% at all time points. No harms related to the intervention were reported. It is feasible to deliver the SIP SMART intervention embedded within the NHS cancer care pathway using a cluster-randomised design. A future trial will be optimised for efficiency in set-up and follow-up data collection based on these findings and learnings from the accompanying process evaluation study. ISRCTN12377415.
