[Blood transfusion practices: about transfusions at night]

Blood transfusion safety covers all stages from prescription of immuno-haematological examinations until the completion of the transfusion. According to the 05/11/2006 Afssaps' decision on good transfusion practices, transfusions should not be given at night unless the patient is actively bleeding or has some other urgent clinical need. A retrospective study was used to assess the proportion of transfusions at night. Through this professional practice evaluation, we analyze the reasons leading to perform transfusions at late hours, in order to reduce errors and improve safety for patients.
