[Blood, blood components and plasma derivatives. Guideline-based implementation].

The transfusion act authorized the German Medical Association to provide "guidelines for therapy with blood components and plasma derivatives" by a working party for the critical use of blood products to help to protect patients from avoidable risks. Responsible and carefully considered use of blood products is mandatory, particularly because obtaining them requires the willingness of numerous volunteers to donate blood. The individual recommendations were evaluated by evidence-based criteria and for many medical interventions so that they will serve to provide comprehensive operational procedures for transfusion personnel in clinics.
