The aim of this study was to identify relevant content among four important domains for the development and structure of a paediatric cardiac rehabilitation curriculum for young patients with congenital heart disease using a consensus approach.

A three-round e-Delphi study among congenital heart disease and paediatric exercise physiology experts was conducted. Round 1, experts provided opinions in a closed- and open-ended electronic questionnaire to identify specific elements necessary for inclusion in a paediatric cardiac rehabilitation programme. Round 2, experts were asked to re-rate the same items after feedback and summary data were provided from round 1. Round 3, the same experts were asked to re-rate items that did not reach consensus from round 2.

Forty-seven experts were contacted via e-mail to participate on the Delphi panel, 37 consented, 35 completed round 1, 29 completed round 2, and 28 completed the final round. After round 2, consensus was reached in 55 of 60 (92%) questionnaire items across four domains: exercise training, education, outcome metrics, and self-confidence.

This study established consensus towards programme structure, exercise training principles, educational content, patient outcome measures, and self-confidence promotion. By identifying the key components within each domain, there is potential to benchmark recommended standards and practice guidelines for the development of a paediatric cardiac rehabilitation curriculum to be used and tested by exercise physiologists, paediatric and adult congenital cardiologists, and other healthcare team members for optimising the health and wellness of paediatric patients with congenital heart disease.
