The reliability of POCUS in the diagnosis of community-acquired pneumonia in critically ill pediatric patients: a cross-sectional study
Abstract
Community-acquired pneumonia represents a noteworthy concern in terms of morbidity and mortality, particularly in countries with lower and middle-income levels. Accurate and timely diagnosis of pneumonia is crucial for optimal management. Chest CT is considered the gold standard imaging for diagnosis of pneumonia, but it is not always readily available and exposes children to radiation hazards, so it becomes important to find easily available and less hazardous imaging tools such as lung ultrasound to diagnose pneumonia. A comparative investigation was carried out to assess the diagnostic capability of lung ultrasound in critically ill pediatric patients presenting with respiratory symptoms. Forty-two patients with community-acquired pneumonia from the pediatric intensive care unit were included. Lung ultrasound demonstrated high sensitivity (88.1%) and specificity in diagnosing pneumonia, outperforming chest X-ray (50%) and providing comparable results to chest CT (95.2%). In addition, 45.2% of patients required mechanical ventilation, and 69.1% were diagnosed with viral pneumonia. The employment of lung ultrasound is deemed secure, accessible, transferable, and efficacious in the expeditious detection of community-acquired pneumonia and the subsequent monitoring of patients. Its high sensitivity and specificity make it a valuable imaging modality in pediatric pneumonia diagnosis, helping clinicians make informed decisions and improve patient outcomes.
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
