Contrôle de qualité des activités de prélèvements homologues: 5 ans d'expérience

Abstract

Quality control (QC) of blood collection activities for transfusion is a regulatory requirement. The authors report on their experience in this field over the past 5 years. In their institution, this QC is based on both the recording and analyzing of predefined data, as well as the search for an active collaboration from each person involved in these activities. QC of medical selection relies on the assessment of several associated criteria: effectiveness of the information given to blood donors for recruitment, preparation of the medical interview and encouragement to perform regular donations; frequency of donors deferred after the medical interview; frequency of biological abnormalities detected at donation; results of the inquiries into the corresponding medical interviews following adverse transfusion reactions. The quantitative and qualitative evaluation of blood collection permits assessment of the quality of the blood collection program, collection procedures and directly derived blood products. Quality assessment of facilities and equipment is also included in this QC. Results have been improving in recent years, especially regarding medical selection. In particular, an increase in the mean donation rate of donors, a decrease in biological abnormalities detected at donation and an absence of adverse transfusion reactions attributed after inquiry to an inadequate medical interview have been noticed. A decrease in both shortage and outdating of labile blood products likewise indicates an improvement of blood collection planning. However, this QC reveals deficiencies in the information given to donors and a lack of analysis of the data specific to first time donors. In order to further improve the efficiency of QC, these results now require comparison with similar data collected on a nation-wide scale.
