Tuberculosis incidence rate among various categories of citizens subject to regular medical check-ups in antitubeculosis facilities due to having contact with tuberculosis patients anslysed using official statistics data
Aim is to establish on the grounds of official statistics data studies the risk rate of tuberculosis incidence among citizens subject to the regular medical check-ups due to having contact with TB patients in comparison to persons not subject to the regular dispensary check-ups. Materials and methods. Retrospective chart review of the reporting form No 33 «Information on Tuberculosis Patients’ in Khanty-Mansiyskiy Avtonomnyy Okrug-Yugra for the period of 1998-2008 was performed and incidence rate among the groups of patients under research was defined. The comparison of incidence rates was made using Kruskal-Wallis and Newman-Keuls criteria. Results and discussion. Having contact with patients with bacillary forms of TB process is a reliably significant criterion of the tuberculosis incidence rate. Family-related (home) contact with TB patients is reliably more hazardous according to the TB incidence rate than work-related contact. In Khanty-Mansiyskiy Avtonomnyy Okrug-Yugra among persons not subject to the regular medical check-ups due to having contact with TB patients the highest TB incidence rate is reliably among adults, teenagers take the second place and the lowest incidence rate is noted among children from this group. Conclusions. Family-related contact with TB patients is more dangerous according to the TB incidence rate than work-related contact. The lowest TB incidence rate among persons subject to the regular medical check-ups due to contacting with patients having a bacillary form is among children. It is likely to be the consequence of TB preventive measures system for children which has been functioning in KhMAO-Yugra during the period analyzed.
