Dr Alex J. Scott is medical doctor and clinical researcher at the University of Cape Town Lung Institute, South Africa. He is currently completing his PhD (Medicine) at the University of Cape Town evaluating the accuracy and clinical utility of AI-driven computer-aided detection (CAD) during community-based active case-finding for TB.
Community-based ACF detected a high burden of TB. A CAD-directed Xpert strategy detected similar proportions of TB compared to universal Xpert testing. Feasibility and cost-effectiveness data are being analysed and will be presented along with the final results to demonstrate the full impact of a CAD-directed Xpert strategy.
