Fortifying the automated smartphone-based Cough Audio classification for rapid triaGE testing for tuberculosis project

Descripción del proyecto

Pruebas innovadoras para la tuberculosis

La tuberculosis (TB) es la enfermedad infecciosa que más muertes causa en el mundo y su repercusión se ha visto agravada por la COVID-19. En el proyecto 4-CAGE-TB, financiado con fondos europeos, se pretende desarrollar pruebas revolucionarias de triaje de la TB. Esta iniciativa se centrará en recopilar los sonidos de la tos en centros de atención primaria de Sudáfrica para crear un clasificador de audio. El clasificador separará a las personas como «TB probable» o «TB improbable» para, a continuación, remitirlas a las pruebas de confirmación. Este clasificador se validará con cohortes independientes de Sudáfrica y Uganda. La investigación con métodos mixtos guiará el diseño y la aplicación del clasificador, que se integrará en una aplicación de salud móvil fácil de usar y con funcionalidad fuera de línea. El objetivo de 4-CAGE-TB es proporcionar una herramienta precisa y validada para su uso en ensayos clínicos.

Objetivo

Tuberculosis (TB) is the single biggest infectious cause of death globally, a situation worsened by COVID-19. Revolutionary new TB triage tests are required, including at facilities where people are accessible and efficiently referable to confirmatory testing. The Cough Audio triaGE for TB (CAGE-TB) study was EDCTP2-funded to 1) collect cough sounds at people’s point-of-entry into primary care facilities (South Africa) and derive an audio classifier, 2) validate diagnostic accuracy in independent cohorts (South Africa, Uganda), and 3) deploy mixed methods research (costing, implementation science, medical anthropology) to inform design and implementation so that this classifier, which will report people as “likely TB” or “unlikely TB” for confirmatory testing, is embedded within a user-friendly mHealth app with on-device offline computation. Per the original call’s objective, CAGE-TB’s goal was to deliver an accurate validated mHealth app usable in trials assessing clinical outcomes (necessary for adoption). Uniquely, this pure mHealth innovation mitigates barriers that jeopardise target product profile criteria (e.g. reagents, cold-chain, transport, infrastructure). After CAGE-TB hired personnel, COVID-19 prevented and slowed recruitment (people had limited clinic access, recruitment interrupted by successive COVID-19 waves). Throughout this, CAGE-TB paid personnel and trainees, resulting in severe budget overruns without participant recruitment, and limited trainee progress and site visits. In 4-CAGE-TB we request essential support over two years to accomplish the original scope-of-work, ensure trainees can finish degrees and, due to the longer recruitment period, accommodate critical additional site visits. COVID-19 has only reinforced our premise: it caused TB to increase for the first time in a decade, damaged already weak facility-based triage practices, and accelerated cough classification technologies.
