Summary

This retrospective observational single-center study aims to evaluate the medical and occupational relevance of systematic screening for latent tuberculosis infection using QuantiFERON-TB Gold Plus during pre-employment occupational health assessment among hospital workers at the University Hospital of Nice. Data will be collected retrospectively from occupational health medical records, immunology laboratory results and, when necessary, data from specialized follow-up by the tuberculosis control center. The primary objective is to determine the proportion of positive QuantiFERON-TB Gold Plus tests at pre-employment screening. Secondary objectives are to identify factors associated with a positive test, to describe the practical consequences of screening, including chest X-ray, diagnosis of latent tuberculosis infection and initiation of preventive treatment, and to estimate the cost of systematic screening.
