The use of a national transplant registry to benchmark transplant outcome for patients undergoing autologous and allogeneic stem cell transplantation in the United Kingdom

As part of its clinical governance programme the British Society for Blood and Marrow Transplantation (BSBMT) undertook an analysis of transplant outcome for adults undergoing human leucocyte antigen - identical sibling allogeneic transplantation for chronic myeloid leukaemia (CML) in first chronic phase (CP1) or autologous transplantation for Hodgkin's disease (HD). The study aimed to compare transplant-related mortality (TRM) and survival for patients reported to the BSBMT with patients transplanted in the rest of Europe, reported to the European Group for Blood and Marrow Transplantation (EBMT). The outcomes for 104 allogeneic transplants for CML in 24 UK/Irish centres were compared with 775 allografts in 145 other European centres. For HD, 241 autografts from 38 UK/Irish centres were compared with 1145 transplants in 239 other European centres. For both diseases, the cohorts were broadly matched with the exception of CML, where 85% of patients were transplanted
