Influence of periodicity of fluorographic examination of population on the frequency of occurrence of bacillary excretion and destructive forms of tuberculosis in persons with the firstly diagnosed disease

Aim: to establish the structure of the relationship between the change in regulations of fluorographic regimen and frequency of occurrence of bacillary excretion (MBT+), destructive forms of the disease in patients with newly diagnosed tuberculosis. Materials and Methods. 1,428 cases with newly diagnosed tuberculosis — a form №089u-tub, as well as other types of reports of the Saratov region have been analyzed. Statistical analysis has been performed by computer software «Microsoft Excel» and «Statistica-6.0». Analysis of the data by the test of Kolmogorov — Spirin has showed normality of their distribution. Confidence index was assessed by Student's. Differences were assessed as valid if the probability was 95% (P<0.05) and higher. Results. The group with the presence of medical and biological risk factors for tuberculosis, for one reason or another do not pass a fluorographic examination in the next 3-5 years, the number of patients with the collapse of the lung tissue was 45.2%, the MBT+ —45.7%. In cases where the lastfluoro- graphic examination performed five years ago, the number of patients with the collapse increased to 58.8% and from the MBT+ — up to 64.3% (P
