01 About BMSS
Blood transfusion carries risk. Removing the need is evidence-based care.
An international society of experts in blood transfusion avoidance, working to make bloodless care the standard — not the exception.
BMSS is an international, multidisciplinary society of experts in blood transfusion avoidance. Founded in 2015, it is a unique medical society committed to improving clinical outcomes and protecting patients’ rights by promoting techniques of total avoidance of allogeneic blood transfusion.
Blood transfusion is associated with hazards and adverse outcomes, without established evidence of benefit. Current scientific evidence suggests transfusion is an independent risk factor for morbidity and mortality across patient groups — while bloodless care is linked to improved outcomes, including shorter hospital stays and lower mortality.
Our mission is to bring the benefits of that evidence to patients and clinicians worldwide, by encouraging the teaching and practice of bloodless medicine, and by supporting research and the dissemination of scientific information.
Our vision
Bloodless care — not as an alternative, but as the global standard of care.
