In a TB outbreak within a shelter, which approach reliably improves medication adherence?

• A. Provide directly observed therapy (DOT)
• B. Arrange for the affected individuals to be admitted to hospital.
• C. Administer the drugs in a sustained-release formula.
• D. Select drugs that have the lowest incidence of side effects.

Answer: (A)

Directly observed therapy helps ensure every dose is taken under supervision, which is crucial for TB because the treatment is long and inconsistent adherence can lead to drug resistance and ongoing transmission. In a shelter outbreak, DOT can be implemented through outreach teams or on-site staff, making adherence feasible without hospitalizing everyone. It also allows ongoing monitoring for adverse effects and support to complete the full course of therapy, which is essential for effective control. Hospitalization is resource-intensive and not usually necessary for all patients in a shelter outbreak. Sustained-release formulations for TB drugs aren’t standard practice and don’t address the need for daily, supervised dosing. Choosing drugs with fewer side effects might help some individuals stay on treatment, but it doesn’t reliably ensure adherence the way direct observation does.
