Pratiques transfusionnelles en court séjour gériatrique avant et après les recommandations de 2014 de la Haute autorité de santé

: Anemia is the most common hematological pathology in geriatrics. Its prevalence increases with age. It is considered as a fragility factor because leading to loss of autonomy and other complications. Transfusion is a common practice in geriatrics. In 2014, the French national health authority guidelines recommended hemoglobin concentration rates for transfusion on the elderly over 80 years-old. The objective of this study is to compare transfusion practices in geriatric short-stay units, before and after these guidelines were edited. METHODS: Retrospective descriptive study in two geriatric short stay units, including patients aged 80 years-old or over, transfused in 2012 and 2015. RESULTS: 103 patients were included. More than 30% patients had a chronic heart failure, and there was no significant difference on general characteristics between the groups in the two years. Compared to 2012, the transfused population in 2015 was more fragile with a higher Charlson comorbidity index (p=0.005). The main symptoms of anemia bad tolerance were cardiovascular symptoms. The average pre-transfusion hemoglobin concentration was 7.9 g/dL in 2015, 8 g/dL in 2012 (p=0.63). By 2015, 72.3% transfusions respected the hemoglobin thresholds recommended in guidelines, compared to 50% in 2012 (p=0.023). Transfusion thresholds in our study were lower than those recommended; 13 adverse reactions were identified, 12 of them were heart failure. There was no significant difference in transfusion benefit between the two years. CONCLUSION: This study helped describe profile of elderly transfused patients, their geriatric characteristics and the transfusion data, without showing any changes in transfusion practices following the guidelines, despite a more fragile population in 2015. It seems difficult, because of the diversity in the geriatric population, to have a single threshold of hemoglobin recommended, only non-specific symptoms of intolerance and to consider only the cardiovascular comorbidities to decide whether or not to provide a transfusion.
