Effect of Pediatric Lung Ultrasound on Antibiotic Prescriptions in Hospitalized Children and Adolescents With Lower Respiratory Tract Infections. A Randomized Controlled Trial.

Lung ultrasound (LUS) is a non-invasive, radiation-free imaging technique that uses sound waves to visualize the lungs. It will be used in the experimental arm to help guide decisions regarding antibiotic therapy in hospitalized children and adolescents with lower respiratory tract infections (LRTIs). The LUS will be performed within 24 hours of enrollment.

In the sham group, participants will undergo a mock or placebo version of the lung ultrasound. This involves performing the procedure in a way that mimics the real ultrasound process but does not provide any diagnostic results or influence clinical decision-making regarding antibiotic therapy.
