A study from Papua New Guinea shows CAD4TB’s effectiveness in detecting TB. Among 7,970 participants, CAD4TB flagged 1,116 for abnormal chest X-rays, identifying 69 Xpert-positive TB cases. This detection rate of 853 per 100,000 exceeds the national TB incidence rate of 432 per 100,000 in 2019. The study underscores CAD4TB’s potential to improve TB detection rates in TB hotspots with healthcare access barriers.
A study explored the implementation of CAD4TB (v6) in Papua New Guinea, focusing on its impact within a community-wide TB screening and prevention programme aimed at continuous quality improvement. The study highlights the effectiveness of CAD4TB in enhancing TB detection and treatment efforts.
