[Control of the transfusion risk in HE: Reflection on the a priori risk approach].

Haemovigilance and blood safety became closely linked initially to the quality system, then very quickly to risk management in health-care institutions. The complexity of the transfusion process and the uniqueness of the transfusion act have been the source of a wide range of in-depth analyzes, via methods most often derived from the industry, that aimed at preventing the occurrence of unwanted situations with potential adverse effects on transfused patients. Though these methods have widely been successful, the experience gained over more than two decades indicates that many reported incidents are still avoidable. The time devoted to training, file analyzes (even in the absence of any reported incident), and simulating patient care remains essential. It is fundamental to bear in mind that there is no such thing as risk zero, no one is immune, and this does not happen to others. In this context, developing a different perspective, a new reflection, a vision integrating the complexity of fieldwork and the idea of risk may be an approach worthy of investigation. Indeed, an analysis centered on both of the ways a team copes with difficult situations and the variety of the interactions between professionals would allow medical practitioner to better position themselves through a better assessment and understanding of their role. Such a deeper reflection, through the mobilization of all the stakeholders of the many successful steps of the transfusion process, would increase blood safety and the overall resilience of the system.
