Utility of eGVHD App for bedside GVHD assessment in a high-volume BMT center.

Assessing acute and chronic graft-versus-host disease (GVHD) is challenging because there are several classification systems. The European Society for Blood and Marrow Transplantation and the Center for International Bone Marrow Transplantation Registry task force recommends using the eGVHD application (App) to score acute GVHD according to the Mount Sinai Acute GvHD International Consortium (MAGIC) criteria and chronic GVHD according to the National Institutes of Health 2014 criteria. We prospectively used the eGVHD App at each follow-up visit in a large-volume bone-marrow transplant center in India from 2017 to 2021. We retrospectively evaluated the discrepancy in scoring GVHD severity by physicians not using the App from the same patient charts. The App user satisfaction and experience were recorded using the technology acceptance model (TAM) and the Post-Study System Usability Questionnaire (PSSUQ). In 100 consecutive allogeneic hematopoietic cell transplantation recipients, there was more discrepancy in scoring the severity of chronic GVHD (38%) than acute GVHD (9%) without using the App. The median TAM and PSSUQ scores were six (IQR:1) and two (IQR:1), respectively, indicating high perceived usefulness and user satisfaction. The eGVHD App is an excellent learning tool for hematology/BMT fellows and helps manage GVHD in high-volume BMT centers.
