The research team assembled to design and oversee the research includes doctors and clinicians, academics, statisticians, administrative staff, and members of the public. Members of the research team have recent experience of successfully completing a national clinical trial of HFNC in children’s intensive care units and considerable experience of conducting clinical trials in other groups of sick children. Two parent representatives from the National Institute for Health and Clinical Excellence (NICE) bronchiolitis guideline committee have also joined our research team to help us develop and oversee the study.
