[Long-term study of the effect of successive surveys on tuberculosis endemia]. / Studiu longitudinal al influentei depistarilor succesive asupra endemiei tuberculoase

A whole rural population of 16359 subjects was followed for a period of 24 years. This period of 24 years is well divided from the viewpoint of the succesive systematic detection three intervals being selected, as follows: a) the stage of usual anti-tuberculous assistance; b) the stage of scientific experimentation consisting in 3 radiophotographic detections repeated every two years and the annual control of groups with high risk, between 1960--1965, completed by integral biological detection in children (every year) and bacteriological controls. The population controls were followed by the diagnosis; c) the stage of discontinuing the experiment when current antituberculous assistance was resumed, between 1966 and 1974. All cases of active pulmonary tuberculosis, that have been recorded through all the methods of investigation over a period of 24 years in all these localities are correlated, on the one hand to one another, and on the other hand with objective documents obtained during the period of intensive control of the population over the 6-years interval. Thus the limits appear more correctly, within which this natural history of the disease can be detected through various types of population control, as well as some practical consequences for the improvement of the technique and of the control methodology in the future.

In the territory of 5 anti-TBC dispensaries in the area of Bucharest 2 circumscriptions have been selected at random in which radiophotographic detection was to be carried out integrally and 2 other circumscriptions were selected for the investigation of groups at high risk of developing tuberculosis. All the new cases of active pulmonary tuberculosis that have been recorded, through all the methods in these 20 circumscriptions in 1973 were analized retrospectively and the reasons appeared that had determined their existence was mentioned or was ommitted on the occasion of previous investigations. These reasons were correlated with the data concerning the method for detection that had been employed, according to the indications of the tuberculosis dispensaries. In view of the evaluation of the degree of real covering of the population in integral rf investigations, the team of the Institute of Phtysiology investigated representative lots of population from each dispensary and checked the catagraphy of the population in the field, house-by-house. It was noted that 20--21% of the subjects that had been programmed for the integral rf examination (according to catagraphic criteria) were absent when the checking in the field, that should have been programmed, were not included in the catagraphy. On the basis of this study the methodology for radiophotographic detection for groups with risk of developing tuberculosis was established.
