[The formation of groups at risk for tuberculosis by means of questionnaires and using computers]

The highest risk groups of tuberculosis origination and recurrences have been ascertained on a large factual material. A multifactorial computed analysis conducted on the basis of the automatized dialogue system made it possible to establish the optimal combinations of the socio-hygienic and medico-biological factors to detect risk groups of emergence of respiratory organs tuberculosis and its recurrences. The main risk group of respiratory organs tuberculosis included subjects adhering to the social way of life, having concurrent respiratory diseases and living under the unfavourable housing conditions. Respiratory organ tuberculosis most probably recurs in subjects who were not fully cured of a primary disease and in those who had an acute disease one year prior to recurrence detection. The developed system helps a practitioner-phthisiatrist in decision making concerning risk groups formation.
