What this research studies

If your child takes part, they would be randomly assigned to care guided by a novel automated digital stethoscope with AI lung-sound analysis or to standard clinical care, and neither you nor the clinician will know which group they are in. The trial is double-blinded and designed to show the AI-enhanced approach is not worse than standard care for preventing treatment failure in low-risk children with non-severe clinical pneumonia. The project also includes on-the-ground studies of how the device could be used in clinics and an economic analysis of costs and savings. The work builds on prior validation of the stethoscope across multiple low- and middle-income settings.

Who could benefit from this research

Good fit: Children aged 0–11 years in Bangladesh with non-severe clinical pneumonia who are considered low risk would be the intended participants.

Not a fit: Children with severe pneumonia, other serious illnesses, or those living outside the study clinics in Bangladesh would not be eligible and are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, the approach could safely reduce unnecessary antibiotic use in young children, lowering side effects and slowing antibiotic resistance.

How similar studies have performed: The digital stethoscope and its lung-sound analytics have been validated over years in several low- and middle-income countries and are FDA-approved, but randomized trials measuring impact on antibiotic use in children are limited.
