We evaluated the use of videophone technology to provide directly observed therapy (DOT) to patients with active tuberculosis. During 304 treatment doses, adherence on videophone DOT was 95%, and patient acceptance of the technology was excellent. In selected cases, the use of videophone technology can maintain a high level of adherence to DOT in a cost-effective manner.
