Preventive measures to reduce the TB spread include its early detection (screening), among key risk groups too. The study aim, provided by using information-analytical and statistical methods, based on own materials, national and foreign publications, data obtained from federal statistical observation forms, is to know the effectiveness of various TB and LTBI screening methods, among vulnerable groups. The study results show that in Russia, along with improvement in the epidemic situation, periodic CXR examinations continue to be the main TB screening method. Effective and modern TB screening methods are used extremely rarely: MGM (6,2%), IGRA-tests for LTBI screening among key risk groups are used non-systemically, mainly among children, along with national ART. Meanwhile, with equal rates of population screening coverage and share of new TB cases found by screening, its detection rate in regions with a high TB incidence is significantly prevailing in regions with a low once (95,0% CI: -0,12 -3,11, p0,02). The obtained data indicate the need for a differentiated approach to provide TB screening measures: in regions with a high TB incidence, to maintain mass CXR screening; in areas with low incidence rates, active TB screening should be carried out only among vulnerable groups, including usage of MGM, ATR and IGRA-tests for LTBI screening, and passive TB screening should be organized among those who seek medical care.<br /><br /></p>tuberculosisvulnerable groupsLTBIscreeningIGRA-testsATRefficacyтуберкулезуязвимые группыЛТИскринингIGRA-тестыАТRэффективность1.Bayanova N.A., Puzhalin Ya.D., Mamedov V.G.
