title: Operational evaluation of treatment for tuberculosis. Results of a "standard" 12-month regimen in Peru.
abstract: To measure the operational effectiveness of treatment for tuberculosis in Peru was evaluated the outcome of a 12-month treatment regimen in 2,510 patients who had tuberculosis diagnosed in 1980. All patients had acid-fast bacilli detected by sputum microscopy and were to be treated with isoniazid, streptomycin, and thiacetazone daily for 2 months followed by either isoniazid and streptomycin twice a week or isoniazid and thiacetazone daily. Only 47% had a favorable outcome, 41% abandoned treatment, 6% failed treatment, 4% died, and 2% relapsed. Of 1,483 patients who completed treatment, 79% had a favorable outcome, whereas 21% had an unfavorable result (treatment failure, relapse, or death). These data indicate that failure to complete treatment is the major reason for the low rate of success but that, in addition, the effectiveness of the regimen in patients who complete treatment is not optimal.
