[A study on the implementation of primary chemotherapy to pulmonary tuberculosis with positive bacillus].

A cohort study on chemotherapy implementation program with regards to newly detected bacillus positive pulmonary tuberculosis patients in 132 medical units was carried out. Results showed that a) one year sputum negative conversion rate was 80%; b) only 48.1% of the patients had received the standardization six--month short--course chemotherapy regimens promoted by M. O. H; c) among 60% of the patients the duration of treatment had been too long; d) the two--year relapse rate of initial drug--resistant patients was 7.6%. The result suggested that the standardized chemotherapy program should be strenghened.
