Clinical Transfusion


promote good clinical transfusion practice globally through education, audits and scientific studies

Clinical transfusion comprises all clinical aspects of blood transfusion and promotes safe practice and appropriate use of blood (components). This includes both the risks and benefits of transfusion as well as close monitoring of patients. Patients should only be transfused when there is evidence for potential benefit. Occasionally, transfusion alternatives might be considered. In order to optimize patient care in need for blood transfusion, it is crucial to follow an evidence-based, multidisciplinary approach. Patient Blood Management (PBM) comprises patient evaluation and clinical management surrounding this decision-making process. This includes application of appropriate indications, minimization of blood loss and optimization of patient red cells. PBM can reduce allogeneic blood transfusions and health-care costs, while ensuring that blood components are available for patients.



We develop educational tools in clinical transfusion medicine both for clinicians and transfusion specialists, medical and non-medical. We support ISBT's library of evidence-based guidelines, audits and perform benchmarks. We also exchange knowledge with other transfusion specialists for optimizing clinical transfusion practice.

We have the following activities:

  • Patient Blood Management (PBM): our website (led by Birgit Gathof) provides PBM resources and tools for implementation, educational activities such as eLearning (led by Cynthia So-Osman and Peter van den Burg) (in progress), Wikipedia project (led by Lise Estcourt), live Journal Club (led by Mark Yazer), I TRY IT co-mentorship,  and performing global benchmark surveys (several subgroups).
  • Shared WHO projects (led by Cynthia So-Osman) such as revision of Clinical use of Blood Manual.

Our Chairperson is Arwa Al Riyami, and our Vice Chairperson is Mark Yazer.


We meet at ISBT congresses and organize annual interim business meetings (located in Amsterdam) and teleconferences within the subgroups (2-3 times per year).

Personal information

Working Party Subgroups

The Transfusion Practitioners

The Transfusion Practitioners subgroup (TP, chaired by Linley Bielby and  Rachel Moss) provides a forum for transfusion practitioners to connect and share knowledge. The Transfusion Practitioners also have their own online discussion forum on the ISBT Forum. If you are interested in joining the forum, please email for more information.


The Paediatric subgroup

This is a shared subgroup (Paeds, chaired by Ruchika Goel) of the Clinical Transfusion and Haemovigilance Working Parties of ISBT. It is an international group of professionals with an interest in neonatal and paediatric transfusion medicine and transfusion safety. The subgroup provides tools for PBM implementation and eLearning regarding neonates and children. 


Patient Blood Management - a great Resource

Patient Blood Management (PBM) is an evidence-based, multidisciplinary approach aimed at optimising the care of patients who might need transfusion. It puts the patient at the heart of decisions made around blood transfusion, promoting appropriate use of blood and blood components and the timely use of alternatives where available. PBM represents an international initiative in best practice for transfusion medicine. The Clinical Transfusion Working Party have put together this resource to help support the wider implementation of PBM. It represents experience from a number of countries and contains 14 chapters on various aspects of PBM.
