Preliminary risk analysis applied to the transmission of Creutzfeldt-Jakob disease.

Transmissible spongiform encephalopathy (TSE) is a degenerative disease of the central nervous system. As yet, there is no human screening test and no effective treatment. This disease is invariably fatal. General preventive measures are therefore essential. The objective of this study is to analyze and address on a prioritized basis the risks relating to the transmission of Creutzfeldt-Jakob disease during surgical operations by means of a preliminary risk analysis (PRA). The PRA produces 63 scenarios with maximum risk relating to operational and legal dangers. The study recommends a number of courses of action, such as training and internal controls, in order to reduce the risks identified. A procedure has been drawn up and assessed for each action. This PRA makes it possible to target and significantly reduce the potential dangers for transmission of Creutzfeldt-Jakob disease through the use of medical instruments.
