What this trial studies

This trial aims to evaluate the effectiveness, cost-effectiveness, and feasibility of two active case finding (ACF) strategies for detecting recurrent tuberculosis (TB) among individuals who have completed TB treatment and their household contacts in Pune, India. Participants will be randomized to either home-based ACF (HACF) or telephonic ACF (TACF), with healthcare workers conducting symptom-based assessments at six-month intervals. The study will also analyze the implementation processes of these strategies and model their impact and cost-effectiveness to inform future scaling efforts.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who have recently completed TB treatment and their household contacts.

Not a fit: Patients currently undergoing TB treatment or those who have not completed their treatment will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved detection and management of recurrent TB, ultimately reducing the burden of the disease.

How similar studies have performed: Other studies have shown promise in using active case finding strategies for TB detection, but this specific comparison of HACF and TACF is novel.
