The purpose of this study is to evaluate the effect of a digital application-based nursing intervention on improving health outcomes among kidney transplant recipients. Following kidney transplantation, patients face critical, lifelong challenges that require strict adherence to immunosuppressive therapy and rigorous self-management behaviors to prevent graft rejection and mortality. This study introduces a dual-component nursing intervention comprising an illustrated educational booklet and the implementation of the "MyTherapy" mobile health application. The study aims to determine whether combining tailored patient education with real-time digital medication reminders and symptom tracking can successfully enhance medication adherence, improve daily self-management behaviors, and reduce the self-perceived burden among transplant recipients during their post-operative recovery phase.
