International audience. Introduction: The laboratory of epidemiology of the institute of radioprotection and nuclear safety (IRSN) and the AREVA company are conducting a morbidity study on active workers from the AREVA site of La Hague. Data used for the study are extracted from disease registration system (called Chimed) monitored by the local occupational health department. To assess the quality of this system, we have cross-matched cancer incidence data from two different sources: local occupational health department and cancer registries (used as a gold standard). Materials and methods: A cancer case is an AREVA worker who has been diagnosed with cancer and whose diagnosis has been registered in the Chimed database between 01/01/1999 and 31/12/2009. The Chimed database and the cancer registries' database were matched in order to calculate sensitivity (capacity to detect the true positives) and positive predictive value (probability that a worker with a positive screening result has the disease). Results. The population study contains 5211 workers of the AREVA site of La Hague. The cross-matching has provided following results: 30 cases were registered in both sources database, 23 cancer cases were registered by cancer registries but not by Chimed and 4 cases were recorded in the Chimed database but not in the cancer registries. Our results show that Chimed's sensitivity is about 57%, using cancer registries as the gold standard. The positive predictive value is about 89%. Discussion and conclusion: Our study has showed that about one cancer case out of two was recorded in the Chimed database. In the present state, the Chimed database cannot be used to perform an exhaustive inventory of cancer cases among active workers. In order to improve nuclear worker cancer surveillance by the local occupational health department, standardized and systematic procedures for cancer data collecting are needed. © 2014 Elsevier Masson SAS.
