Factibilidad de una aplicación móvil para el monitoreo de contactos de tuberculosis multidrogorresistente en Perú

Abstract

This study aimed to validate an ODK digital mobile application (ODK-DMA) in contacts exposed to multidrug-resistant tuberculosis (MDR-TB) in Lima, Peru. Using a questionnaire in an application on a mobile device, we registered 129 household contacts of 29 index cases of MDR-TB under treatment in 10 health facilities in South Lima in August 2018. The mean time of registration per contact was found to be 4 minutes. The prevalence of active TB symptoms among MDR-TB contacts was 3.1%. An acceptability questionnaire was completed by 31 respondents; all reported feeling comfortable or very comfortable with recording their data in the ODK-DMA, although 10% expressed concerns about confidentiality. We concluded that the ODK-DMA was a feasible and acceptable tool for registering household contacts exposed to cases with MDR-TB. Future studies should consider the use of mobile platforms for the monitoring of MDR-TB contacts.
