Connaissances et pratiques du personnel soignant en matière de sécurité transfusionnelle

Abstract

Blood transfusion is a complex activity, involving many actors. It is a high risk activity which couldn't be controlled without the use of specific methods. Health care workers beliefs and organisational factors are two major issues for the blood transfusion safety. Our study objectives were to describe the paramedical staff's knowledge and practice regarding blood transfusion safety and to identify factors that are related to them. We carried out a cross sectional study. The information was gathered by using a questionnaire. The latter was developed by foreign teams and adapted to the local context. Two outcome measures were used: the knowledge and practice score and the proportion of true answers. The study showed that only 15% of the interviewed persons have had a score less than 30 (scale range from 0 to 100), i.e. only 15% have had appropriate knowledge and practice with no negative consequences for the patient safety. 13.8% of the study population provided right answers related to the biologic exams required before red cells transfusion and 34% for the abnormal reaction circumstances. These results underscores the importance of strategies improving the quality and the safety of blood transfusion, i.e. the continuous medical education, implementing a blood transfusion information system and the use of transfusion practice guidelines.
