Design and Application of a Home Care WeChat Mini-Program for Children After Congenital Heart Disease Surgery

This is a single-blind, randomized controlled trial aimed at evaluating the effectiveness of a family-centered, WeChat-based home care mini-program for children after congenital heart disease (CHD) surgery. Given the chronic nature of post-operative CHD management and the significant stress placed on families, this study shifts from a deficit-based to a strengths-based perspective, guided by the Double ABC-X model. Children (≤12 years old) who have undergone CHD surgery and their primary caregivers will be recruited. Participants will be randomly assigned to either the intervention group, which uses the mini-program for health education, peer support, and physiological monitoring, or the control group, which receives routine telephone follow-up. The primary outcomes are family health (measured by the Family Health Scale), family stress, and the quality of life for both the child and caregivers. Secondary outcomes include physiological parameters such as the 6-minute walk test distance. The study aims to provide evidence for a scalable digital health intervention to support long-term family adaptation and child recovery.
