Many patients with smear positive tuberculosis were hospitalized during the initial phase of chemotherapy but DOT was not applied to patients with tuberculosis in Japan. We tried randomized clinical study to evaluate the usefulness of DOT during admission. 135 culture positive TB patients were administered by DOT and 124 culture positive TB patients were self-administered during admission. There was no significant difference between 2 groups in the clinical background factors, treatment and the incidence of adverse reactions. Treatment completion rate was 94.1% in DOT group and 87.9% in non-DOT group. Default rate was significantly lower in DOT group (4.4%) than in non-DOT group (11.3%). We concluded that "DOT during admission" was useful to improve the outcome of chemotherapy for tuberculosis and it is preferable to apply DOT throughout treatment course for patients with tuberculosis in Japan.
