Disease Surveillance Epidemiology Program

Tuberculosis - Directly Observed Therapy

The Maine Tuberculosis (TB) Control Program and Division of Family Public Health Nursing Services adopted DOT as the standard of care for persons diagnosed with active TB.

As defined by The Centers for Disease Control and Prevention (CDC), DOT is when a health care worker or other designated individual directly observes the patient swallow the prescribed drugs. Household members should not hold responsibility for DOT.

The Centers for Disease Control and the American Thoracic Society recommend that DOT be considered for all patients as a method of ensuring adherence to a medication regime. In Maine, DOT is used for all patients with active, infectious TB disease and may be used for patients with extrapulmonary TB disease. DOT may include the use of incentives and enablers to encourage adherence.
