Highlights
The TRICORDER trial, a large-scale cluster-randomised study in the UK, found that implementing AI-enabled stethoscopes in routine primary care did not significantly increase the incidence of newly coded heart failure diagnoses compared to standard care (IRR 0.94; 95% CI 0.86-1.02).
While the AI stethoscope algorithms have proven diagnostic accuracy for heart failure, atrial fibrillation, and valvular heart disease, the population-level impact was limited by real-world implementation challenges and clinician uptake rates.
