During a tuberculosis outbreak at a shelter, which action best ensures treatment adherence?

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

Answer: (B)

The point of the question is how to make sure people stick with their TB treatment in a crowded shelter setting. Directly observed therapy means a health worker or trained observer watches each dose be taken, and often accompanies patients for the full course. This tackles the biggest barrier to TB cure: incomplete treatment. When doses are observed, it’s easier to ensure every drug is taken on schedule, side effects are monitored, and people are supported to continue therapy until it’s finished. In an outbreak at a shelter, delivering DOT on-site keeps treatment consistent, reduces the chance of missed doses, and helps prevent drug resistance and ongoing transmission. Hospital admission, while sometimes needed for severe illness, isn’t practical or necessary for every patient and can disrupt shelter operations. Sustained-release formulations aren’t a standard approach for TB therapy, which relies on a multi-drug daily or closely supervised schedule rather than depot dosing. Choosing drugs solely for the fewest side effects doesn’t guarantee adherence or effectiveness, especially if the regimen isn’t completed or is inappropriate for the patient’s infection. So, directly observed therapy best ensures that treatment is completed correctly and consistently in this scenario.
