[Training, skill and competences' follow-up].

Blood transfusion safety is a public health requirement, which is claimed by public health authorities and blood users too. In order to comply with transfusion safety, available national regulatory requirements must be strictly followed (or applied) by blood transfusion workers, caring nurses and physicians. Transfusion's good practices are based on knowledge of the process and the skill in blood transfusion fields. Quality systems, risks management, audits, inspections and certification programs implemented by blood establishments and patients' care services should lead to efficiency. All professionals involved in blood banking and transfusion processes (blood donation, preparation and storage of blood products, transfusion therapy...) must be qualified. They have to follow a program of continued training education. Their competence or ability must also be periodically assessed and documented to let continue and perform tasks safely.
