Tuberculosis control practices in major metropolitan health departments in the United States. 3. Standard of practice in 1984.

Twenty-eight metropolitan health departments in the United States reporting more than 200 cases annually were surveyed to determine the standard of practice in the control of pulmonary tuberculosis. The results were compared to previous surveys done in 1978 and 1980 to determine the impact of policy changes recommended by the American Thoracic Society, American College of Chest Physicians, and Centers for Disease Control and recent reports of innovative chemotherapeutic methods. A high degree of uniformity in chemoprophylaxis practices again was demonstrated. In contrast to our previous survey of 1980, most programs now use rifampin-containing regimens with short (less than 12 month) course chemotherapy as the primary initial treatment regimen for tuberculosis. Mean duration of treatment for tuberculosis decreased from 20.2 +/- 2.1 months in 1980 to 11.7 +/- 1.0 months in 1984. Intermittent chemotherapeutic regimens also were used more frequently in 1984. However, substantial variance from other recommended guidelines still is prevalent among the major metropolitan programs in the United States.
