Abstract
AIM: To review the selection, measurement and reporting of outcomes in studies of interventions in Congenital Diaphragmatic Hernia (CDH). METHODS: We searched the Cochrane Central Register of Controlled Trials from 2000-2020 for randomised trials and observational studies. Outcomes reported were classified into seven key domains modelled on the patient journey. RESULTS: Our search yielded 118 papers; 27 were eligible. The most frequent domains measured were 'short-term markers of disease activity' (17/27), whereas long-term outcomes (3/27) and outcomes relating to functional health status (8/27) were reported infrequently. There was heterogeneity in the methods and timing of outcome reporting. Primary outcomes were varied and not always clearly stated. CONCLUSION: Long-term health and functional outcomes involving interventional studies in CDH are infrequently reported, which hinders the process of shared decision-making and evidence-based healthcare. A CDH core outcome set is needed to standardise outcome reporting that is relevant to both families and healthcare teams.
