The “eGVHD App” is developed by the UZ Leuven (Belgium) in collaboration with the EBMT (European Bone Marrow Transplantation Society) Transplantation Complications Working Party and the National Institute of Health (Bethesda, USA). It is an electronic tool designed as an algorithm-driven application, to help clinicians apply the internationally recognized criteria for the assessment of graft versus host disease (GVHD), a pleiotropic disease affecting allogeneic stem cell transplantation recipients when their transplanted stem cells react against their own body. This app is not a medical tool aiming at replacing the diagnosis of a clinician, but a user-friendly educational tool. It helps health care professionals improve their ability to diagnose and score the severity of GVHD by showing the user differential information and it making an automatic summary of what has been filled in.
