ARCHIVES OF DISEASE IN CHILDHOOD(2021)
摘要
OBJECTIVE:To establish the feasibility of a multicentre randomised controlled trial to assess the effectiveness and cost-effectiveness of a non-operative treatment pathway compared with appendicectomy in children with uncomplicated acute appendicitis.
DESIGN:Feasibility randomised controlled trial with embedded qualitative study to inform recruiter training to optimise recruitment and the design of a future definitive trial.
SETTING:Three specialist paediatric surgery centres in the UK.
PATIENTS:Children (aged 4-15 years) with a clinical diagnosis of uncomplicated acute appendicitis.
INTERVENTIONS:Appendicectomy or a non-operative treatment pathway (comprising broad-spectrum antibiotics and active observation).
MAIN OUTCOME MEASURES:Primary outcome measure was the proportion of eligible patients recruited. Secondary outcomes evaluated adherence to interventions, data collection during follow-up, safety of treatment pathways and clinical course.
RESULTS:Fifty per cent of eligible participants (95% CI 40 to 59) approached about the trial agreed to participate and were randomised. Repeated bespoke recruiter training was associated with an increase in recruitment rate over the course of the trial from 38% to 72%. There was high acceptance of randomisation, good patient and surgeon adherence to trial procedures and satisfactory completion of follow-up. Although more participants had perforated appendicitis than had been anticipated, treatment pathways were found to be safe and adverse event profiles acceptable.
CONCLUSION:Recruitment to a randomised controlled trial examining the effectiveness and cost-effectiveness of a non-operative treatment pathway compared with appendicectomy for the treatment of uncomplicated acute appendicitis in children is feasible.
TRIAL REGISTRATION NUMBER:ISRCTN15830435.
