[Towards global security in radiation oncology. Using event notification feed-back].

Large modifications are on going in our medical practice in oncology (cancer incidence, ageing, rules, authorizations, billings...). To obtain the best results as possible implies a quality control of the equipments (drugs, machines...), of the professionals (certification) and of the organisations (accreditations). Radiation oncology plays a key role in the multidisciplinary treatment of cancer ant is very sensitive to quality assurances due to its specificities: different tumours, various patients, multiple sequences of treatment with high tech machines and information systems. From 2003, a progress policy has been developed with the MeaH (Mission d'évaluation et d'audit hospitalier). Rapidly, the transfer of security policies from industry to medicine has been considered. This paper will present the first results and their potential implications in the field of oncology.
