ABSTRACT
Managing new innovations in medicine is a particularly timely subject. There is an abundant history concerning over expectations resulting from the development of new treatments or diagnostic procedures, some shown to be less effective than promised, others even found to be dangerous. A new aspect to the question is the importance of economic pressures which require rational investment decisions when diffusing innovating technologies. In 1991, the Commission for the evaluation and diffusion of innovating technologies (CEDIT) at the University Hospitals of Paris (Assistance Publique-Hôpitaux de Paris) developed a programme aimed at better managing the distribution and use of polyvalent intravenous immunoglobulins (IgIV), a new promising therapeutic tool with both a high cost and a certain number of risks. The programme was designed to assist prescribers in elaborating better therapeutic strategies and to help hospital managers rationalize expenditures for IgIV. The results of this experience are presented here together with certain conclusions concerning the way management decisions can be applied to the diffusion of an innovation in health care.
