RESUMO
Following the 1995 national reorganization of the transfusion system, the Nord Pas de Calais blood transfusion center has modified its blood collection organization, with the creation of four districts divided into three or four subdivisions. This change was part of Quality Assurance implementation in the center. This article provides the job description for a physician in charge of such a subdivision as well as the method chosen to design this description (inspired by the diagram of Hijman). This job was conceived as an association of human skills knowledge with the strategy of the blood center. In addition to his medical activity, the district subdivision physician becomes a manager and an organizer. The method used highlights the participation of all disciplines involved in blood donation.
