[Suitability of red blood cell transfusion: a multicenter study].
The purpose of this retrospective observational multicenter study was to assess appropriateness of red blood cell (RBC) transfusion, according to the French national guidelines (Agence française de sécurité sanitaire des produits de santé) published in 2002. Six hundred and thirty-nine RBC transfusions from nine institutions have been randomly selected and analysed. The data collected are issued from different specialities. Patients' characteristics, occurrences of transfusion, admission, pre-transfusion, post-transfusion and discharge haemoglobin concentrations have been collected. Two physicians (who are in charge) must evaluate the appropriateness of pre-transfusion, discharged haemoglobin concentrations, quantity and quality of transfused RBC. The mean pre-transfusion haemoglobin concentration was 7.89 ± 1.24, the median number of transfused RBC was two (extremes: 1-16), the mean discharge haemoglobin concentration was 10.14 ± 1.30 (-5 days after the end of transfusion). The pre-transfusion and discharge haemoglobin concentrations were higher if the patient presented a co-morbidity factor. Ninety-three percent of pre-transfusion and 79% of discharge haemoglobin concentrations are in accordance with the guidelines. According to the physicians, the RBC transfusions are too "precocious" when pre-transfusion haemoglobin concentration is above nine and the anaemia is asymptomatic. 50% of RBC transfusion with discharge haemoglobin concentration above 10 is not excessive. In case of acute anaemia, the pre-transfusion and discharge haemoglobin concentrations are higher and RBC transfusion excessive. In this study, the trigger haemoglobin concentration is "restrictive", but the target haemoglobin concentration is "liberal" with a high-discharge haemoglobin concentration. Inappropriate RBC transfusions are mainly due to over-transfusion.
