Pneumonia Clinical Trial
Official title:
Effectiveness of Point-of-care Lung Ultrasound vs Chest X-ray for the Management of Childhood Lower Respiratory Infections in Low-resource Setting: Single Center, Pragmatic, Open-label, Randomized, Controlled, Non-inferiority Clinical Trial
The goal of this clinical trial is to evaluate the effectiveness of point-of-care lung ultrasound versus chest X-ray for the management of childhood lower respiratory infections in a low-resource setting. The main question it aims to answer is: Is point-of-care lung ultrasound as effective as chest X-ray for the management of childhood LRIs in a low-resource setting? Participants will be assigned to either a point-of-care lung ultrasound group (intervention) or a chest X-ray group (control), to compare the effect on overall case management and various clinical outcomes (time to symptom resolution, rate of antibiotic use, length of stay, treatment costs).
Background: Lower respiratory infections (LRIs) are the leading causes of mortality in children of low-middle income countries (LMICs) including Nepal; pneumonia being the major killer in under-5 population. Often, the cause of mortality is the delay in diagnosis and treatment, particularly when clinical assessments do not hint toward a diagnosis. In resource-limited settings, routine availability of chest X-ray (CXR) service is a challenge, it can be hazardous to children due to exposure to ionizing radiation. The Point-Of-Care Lung UltraSound (POCLUS) could be an alternative solution for the diagnosis and management of LRIs. Studies have already shown that lung ultrasound has a higher sensitivity and specificity than CXR in diagnosing childhood LRIs, however, none of the studies have yet evaluated its role in overall case management. Methods: Prospective, single-center, pragmatic, open-label, randomized, controlled, non-inferiority clinical trial, which will be conducted in the outpatient and emergency departments of a pediatric hospital in Nepal. A total of 616 children with clinical suspicion of LRI and requiring chest imaging will be randomized at 1:1 allocation to the intervention (POCLUS) and control (CXR) arms. Pediatricians will be trained to perform lung ultrasonography in children. Outcomes: Primary outcome is the proportion of 'correctly (effectively) managed' cases. Secondary outcomes include the proportion of cases with 'change in diagnosis and management plan due to intervention', time to symptom resolution, rate of antibiotic use, length of stay, and in-hospital costs, compared between intervention and control groups. ;
