[Problems in the formation of tuberculosis epidemiological parameters].
The information obtained from 83 subjects of the Russian Federation on 107,306 new tuberculosis (TB) cases and TB relapses, recorded for treatment in the tuberculous facilities of the Ministry of Health and Social Development of the Russian Federation (RF), was analyzed. The completeness and validity of indicators and their compliance with Russian Statistics Committee's form 8 were studied.


RESULTS
among the new TB cases, bacterial discharge was found in 33.3 +/- 5.2% by microscopy and in 44.9 +/- 8.9% by cultures tests. Decay cavity was observed in 42.6 +/- 4.9% of the patients. In the RF, the coverage of patients to be tested for Mycobacterium tuberculosis susceptibility was 76.3-83.1% of culture-positive TB patients. Among the new TB patients, drug resistance (DR) of M. tuberculosis to one drug or more was detected in 30.6 +/- 6.7% of those tested for drug susceptibility. Multidrug resistance (MDR) was recorded in 11.4 +/- 4.2% of the examinees. Among the patients with TB relapses, DR and MDR were found in 45.4% and 24.7% of the examinees, respectively. The detection rate of epidemically dangerous patients in the general health care facilities was as high as 12.5%, which is an extremely low value.


CONCLUSIONS
Order No. 50 reporting documents needs to be improved for the evaluation of the efficiency of treatment and monitoring a tuberculosis epidemic process. It is necessary to follow the uniform rules for calculating the values for all RF reporting forms. In particular, this concerns the indicators of the prevalence of DR tuberculosis. The efficiency of a microbiology study of patients varies in federal districts; however it is generally inadequate.
