Prof Peter Shaw is a senior staff specialist in Paediatric Blood Transplant and Cell Therapies (BTCT) at the Children’s Hospital at Westmead and Clinical Professor in the Speciality of Child and Adolescent Health, Faculty of Medicine and Health at The University of Sydney. He has over 40 years of clinical experience in paediatric bone marrow, blood and cell transplant. His first exposure to BMT at Westminster Children’s Hospital, the site of the earliest BMTs in the UK for inborn errors such as MPS 1 and Gaucher’s disease, was also the start of his reporting to the then IBMTR. He has served on the CIBMTR Advisory Committee and taken CHW through 2 CIBMTR data audits, before switching primary reporting to EBMT. International Collaboration as part of the Children’s Oncology Group required participating centres to be accredited by FACT from 2007 onwards, and so started a 5-year process leading to FACT-accreditation, becoming a FACT inspector along the way. Although his primary research has been in improving patient outcomes through optimising conditioning, you can only improve if you report what you do, and check what you are reporting is accurate.
