[Role of health care facilities in verifying the diagnosis of respiratory tuberculosis by laboratory methods].

Reasons for laboratory misdiagnosis that is observed in general health care network (GHCN) and penitentiaries were studied. The clinical efficiency of the diagnosis of tuberculosis in the GHCN by the Ziehl-Neelsen method is largely determined by three major factors, each of which is fundamentally important in assessing the result. The first factor is the adequacy of making up a cohort of patients having the symptoms of productive cough in the course of 2-3 weeks or more who are to be examined for tuberculosis by laboratory studies.

[Monitoring of the detection of new pulmonary tuberculosis cases and the efficiency of their treatment in the area supervised by the Central Research Institute of Tuberculosis, Russian Academy of Medical Sciences].

The results of the detection and treatment of new pulmonary tuberculosis cases in 2006 were assessed in 15 subjects of the Russian Federation, supervised by the Central Research Institute of Tuberculosis, Russian Academy of Medical Sciences. As compared with 2005, in 2006 the proportion of bacteria-discharging individuals increased among the new cases of pulmonary tuberculosis and ranged from 77.1% in the Oryol Region to 35.

[Cardinal problems of the regional bacteriological laboratories of tuberculosis facilities].

Restructuring the health care system and the epidemiological situation associated with tuberculosis result in an increased burden on the bacteriological laboratories (BLs) of tuberculosis facilities. At present, there are no statistical data that enable one to estimate the capacity of a laboratory service to assure the adequate quality and efficiency of bacteriological diagnosis. To assess the state of the headquarters BLs of tuberculosis facilities, the authors have worked out a questionnaire to glean necessary information on the activity of the laboratories to such an extent that suffices to reveal cardinal problems in the work of individual laboratories and the laboratory network as a whole.
