Routine follow-up of patients with treated pulmonary tuberculosis.

A retrospective study was made of the rate of relapse amongst 341 patients with treated pulmonary tuberculosis on follow-up for five years. All patients received a total of 18 to 24 months of chemotherapy with the primary antituberculous drugs and were divided into two groups-regular and irregular (with chemotherapy). In the "regular" group the average rate of relapse was less than one per cent per year as compared with a three -fold increase in the "irregular ' group. In none of the relapses in the "regular" group was co-operation in the taking of drugs noted as good. In view of the low yield, it is concluded that the practice of routine follow-up of adequately treated patients with pulmonary tuberculosis is not necessary and should be abandoned.
