Modèle de coopération médico-pharmaceutique comme contributeur au succès du conditionnement de la greffe allogénique de cellules souches hématopoïétiques chez l'adulte : un regard croisé sur nos organisations

Allogeneic hematopoietic stem-cell transplant (allo-SCT) remains the only cure for many hematological malignancies and some benign and congenital diseases. Busulfan, proposed in its injectable form, has quickly become a mainstay of pharmacological and myeloablative (or non-myeloablative) conditioning. This is following the outbreak in 2010 of a multicenter international clinical phase II trial, we tested the robustness and reliability of our organization in a complex model of organization and multifactorial partnership. In this type “BuCy2” protocol based on a classical treatment duration of 4 consecutive days, the administration of IV busulfan is given in one single daily infusion instead of the conventional 16 infusions, while keeping the same total dose. Under these conditions, the treatment is totally secured using a therapeutic drug monitoring of busulfan, applied in real-time. The process is technically complex and requires the very close cooperation of the teams involved. A strength, weakness, opportunity and threat (SWOT) analysis has been constructed; it fully supports continuous quality improvement to the triple benefit of the nursing chain, the patients and their environment. Several critical points were identified and corrected. The experiment strongly contributes to the safety and security of the medication circuit at the hospital and, improves the performance of allo-SCT. It also contributes to the protection of all actors in the health field and their working environment via a well-functioning quality management system.
