Feasibility Testing a Decision-support Intervention for Clinical Trials

A decision-support intervention are developed for a Danish nationwide randomised controlled trial (RCT) among patients with laryngeal and pharyngeal cancer referred to curative intended radiotherapy. The primary endpoints in this RCT are levels of dysphagia and xerostomia. The decision-support intervention consists of three components, including (1) a patient decision aid tailored to clinical trial participation and (2) decision coaching consultations carried out by trained healthcare professionals. Finally, (3) a training program in decision coaching will be an integrated part of the intervention. To feasibility test (beta test) the intervention, 60 patient participants will be included, separated into pre- (n=30) and post- (n=30) intervention groups. Pre-intervention to complete the survey based on current clinical practice. Post-intervention to complete the survey following engagement in the decision support intervention. A total of 12 physicians will be recruited and trained in decision coaching. To assess the acceptability of the intervention, the physicians will be interviewed. Additionally, they will be asked to audio-record two decision coaching sessions to test the fidelity of the intervention.
