The authors elaborated an automated preventive system and examined by means of it 1000 probands with regard to the incidence of cardiovascular and bronchopulmonary diseases and analyzed the results. In the submitted paper they present the results of an analysis of agreement of conclusions of examination made in the traditional way by the doctor and those obtained in the automated diagnostic preventive system. Agreement in the sense of a positive statement (presence of disease) was recorded in 54.1%, agreement in the sense of a negative finding (disease not detected) was recorded in 28.7%. Falsely negative conclusions (the doctor detected the disease, the system did not) were found in 5.6% and falsely positive conclusions (the doctor did not detect the disease, the system did) were found in 11.6% of the patients. The calculated sensitivity of the system is 0.90 and the specificity 0.72.
