Mobile Health and Oral Testing to Optimize Tuberculosis Contact Tracing in Colombia

Yale University·interventional·Posted Mar 29, 2024·Updated Oct 9, 2025

In Brief

A clinical study evaluating Chatbot and Oral testing for Tuberculosis. Completed, enrolled 269 participants across 1 site.

Detailed Summary

The overall objective of this Aim is to design and iteratively adapt a home-based, mHealth- and oral testing facilitated strategy for implementing tuberculosis (TB) contact tracing in Cali, Colombia. Investigators will employ an iterative, community-engaged, participatory co-design process to optimize the feasibility, acceptability, usability, and appropriateness of the mobile health (mHealth) and oral testing strategy, in preparation for a future, appropriately powered implementation-effectiveness trial. This protocol includes the baseline contact tracing protocol and the procedures for determining adaptations to the mHealth strategy (i.e., nominal group technique).

Interventions

Chatbotdevice

The chatbot is a WhatsApp-based, artificial-intelligence powered customer service agent adapted for TB outreach. The objective of the Chatbot is to facilitate information gathering, education, and support throughout TB contact evaluation, ensuring accessible assistance on-demand during and after contact tracing procedures. It operates in a secure data environment that includes end-to-end encryption and has been reviewed and approved by the data protection team within the information technology unit at the Cali Secretariat of Public Health (SoPH) for the study purposes.

Oral testingother

Oral testing involves collection of a saliva sample or use of a nylon swab to collect material from the tongue and oral mucosa that is then tested with a molecular test for Mycobacterium tuberculosis
