Brief Summary

Current Danish studies emphasize the importance of better integrated and efficient lifelong health care to heart-transplant recipients regardless of socioeconomic position. Our objective is to design and evaluate a new digital patient-centered and socially differentiated program after heart transplantation in Denmark. Investigators use a participatory approach with involvement of users: 1) Design phase: Mobile health app; Patient-reported outcomes; Case manager function, 2) Feasibility Study with 25 recipients and process evaluation within 1 month, 3) Randomized Study, including 200 recipients followed for 1 year. Effectiveness is measured as cross-sectional care utilization; costs; events. Efficacy is measured as adherence to pharmacotherapies, labor market participation, and quality of care. Nationwide registers will be linked with interview data, surveys, and app login. This digital transformation of cross-sectional care after heart transplantation will facilitate equality in health.
