Physicians are overloaded with the new Health Department rules about follow-up of transfused patients. Indications of fresh frozen plasma must be restricted and its use must be decreased; patients must be informed before and after transfusion and all informations about transfusion must be collected in a special file. This file will permit to answer the question: "Who received what?" Incidents occurring during transfusion need to be collected and transmitted to the "Centre National d'Hémovigilance". Such a policy will be effective only with an actual help (i.e. financial help) of the administration.
