Tuberculosis Clinical Trial
Official title:
Mobile Health and Oral Testing to Optimize Tuberculosis Contact Tracing in Colombia
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).
This study will examine the diagnostic performance of oral samples for TB molecular testing in clinic and household settings; as well as utilize a community-engaged design methodology to iteratively refine a mHealth strategy for implementing contact tracing optimized for feasibility, acceptability, usability, and appropriateness. There is a Certificate of Confidentiality in place for this study. After contact tracing procedures have concluded, investigators will administer study instruments to characterize the feasibility, acceptability, appropriateness, and usability of the chatbot. Investigators will also conduct up to ~12 key informant interviews with purposively sampled index persons with TB and their household contacts to elicit views on the mHealth strategy during each cycle (for a total of up to ~36 key informant interviews). After ~40 households (index persons with TB and their household contacts) have been enrolled using these procedures, and all scales and key informant interviews have been completed, the mHealth implementation strategy will be adapted using nominal group technique. Investigators will repeat this cycle twice for a total of three rounds of design and adaptation of chatbot-facilitated contact tracing procedures. ;
