Abstract
Initial hospitalization terminated by discharge upon medical advice to continue with chemotherapy on an outpatient basis represents the treatment of choice for most patients with active pulmonary tuberculosis. Any departure from this plan for any patient should be accepted only after careful consideration of all the circumstances. Patients with active pulmonary tuberculosis who are to receive outpatient chemotherapy without adequate initial hospitalization should be carefully selected by the local or provincial department of public health. Approval in writing should be required from the appropriate public health authority before antituberculosis chemotherapy is provided at public expense for any such patient, except possibly for a limited period while awaiting formal approval. In all instances, the clinic which dispenses the antituberculosis drugs should have the patient under supervision with recall for follow-up examinations as required. Prophylactic antituberculosis chemotherapy may be provided to certain groups of persons without hospitalization.
