Artificial intelligence (AI)-enabled digital stethoscopes are revolutionizing global healthcare screening, particularly in detecting lung and cardiovascular abnormalities. Collaborative research from McGill University and partners in the UAE, Germany, and Switzerland highlights their promising accuracy in early-stage tuberculosis (TB) studies, suggesting these tools could be pivotal in large-scale screening programs. AI-driven stethoscopes provide a more accessible alternative by interpreting acoustic biomarkers—subtle sound patterns that indicate disease, often undetectable by the human ear. This includes analyzing cough sounds and lung auscultation signals to identify abnormal respiratory patterns linked to TB. Evidence from high-burden countries like India and South Africa indicates that AI-enabled auscultation is effective for TB screening and triage. These digital stethoscopes may serve as practical alternatives to imaging-based TB detection, democratizing healthcare access for underserved populations, and enhancing the future of disease diagnostics in global health settings.
