[Structural or functional relationship between immunohematology and distribution - Which elements for controlling risks?]

Transfusion safety is based on the availability of safe and compatible blood products at the right time and to the right patient, and requires close monitoring in order to detect possible incidents. The decree of June 20th 2018, which establishes the national blood transfusion's guiding plan, states that the organization that prevails throughout the national territory is built around an inseparable link between the implementation of erythrocyte immunohematology and the labile blood products delivery by authorised structures. The article describes the two types of the link's organization, structural or functional, used to develop the comparative risk-benefit analysis. The structural link, which has fewer interfaces, reduces risk situations that lead to delays in release by default of a compatible product. The cases in which a functional link may have a greater benefit than the risks generated are those related to a geographical distance between the delivery site and the patient's place of care. In these cases, a functional link is possible provided that certain organizational points are mastered. The comparative analysis shows that the structural link is to be favoured since that the coherence of the patient's care and his care path is ensured. In certain situations, mainly geographical, the functional link can have a benefit that offsets the risks generated by the new interfaces; provided that the system is secured by a real tripartite collaboration between health care institution, biology laboratory and delivery site.
