Screening for active and latent TB among migrants in France.

SETTING: Migrants to Europe face a disproportionate burden of infections, including TB, yet little is known about the approach taken by primary and secondary care providers to screening and treatment. We therefore explored policy and practice relating to screening of active TB and latent TB infection (LTBI) in France.METHODS: We conducted an online national survey of French primary and secondary care physicians regarding their practices in relation to TB/LTBI screening among migrants.RESULTS: 367 physicians responded to the questionnaire among which 195 (53.1%) were primary care physicians, 126 (34.3%) were TB specialists in secondary care, and 46 (12.5%) other physicians; 303 (85.5%) were involved daily in the care of migrants. Most respondents recommended systematic TB screening with chest X-ray for migrants from medium and high-incidence countries (71.9%). Primary care physicians were less likely to offer screening than physicians in other settings (aOR 0.21, 95% CI 0.09-0.48). 220 (61.8%) offered LTBI screening for children (<15 years) and 34.0% for all migrants from high incidence countries.CONCLUSION: Improving awareness on TB screening is a critical next step to improve health outcomes in migrant groups and meet regional targets for tackling TB.

Potentially preventable tuberculosis cases in children exposed to a contaminant case.

Early screening is recommended in children exposed to a contagious case of tuberculosis (TB), to prevent rapid progression to active TB. The aim of this study was to evaluate the percentage of potentially preventable cases of pediatric TB stemming from inadequate screening. The data gathered on children aged 0 to 10 years, who were evaluated by the Paris Center for TB Control (CLAT75) between January 2009 and December 2013, were extracted and retrospectively analyzed. French National Guidelines for screening were used as reference. During the study period, 1232 children 0-10 years were screened, because of a known exposure to an index case, including 124 (10%) with criteria for latent tuberculosis infection (LTBI) and 26 (2%) with active TB. Twelve additional cases of TB were reported, diagnosed based on symptoms or systematic exams. As a whole, 68% of pediatric TB cases were diagnosed at screening around an adult index case, highlighting the quality of the screening network. Among the 38 TB cases, 19 (50%) had a missed opportunity for potential prevention, due to the absence of screening despite a known contaminant (n=2) or to screening not in compliance with current recommendations (n=17). Delayed first evaluation was the most frequent error of the screening procedures. In conclusion, despite the quality of the screening network set up in Paris, half of the pediatric TB cases in this study did not undergo the recommended screening procedures. A significant reduction in the number of pediatric TB cases can be expected through the optimization of screening networks.
