Description
Background Lung ultrasound (LUS) is an effective tool for diagnosing pneumonia; however, this has not been well
studied in resource-limited settings where pneumonia is the leading cause of death in children under 5 years of age.
Objective The objective of this study was to evaluate the diagnostic accuracy of bedside LUS for diagnosis of pneu-
monia in children presenting to an emergency department (ED) in a resource-limited setting.
Methods This was a prospective cross-sectional study of children presenting to an ED with respiratory complaints
conducted in Nepal. We included all children under 5 years of age with cough, fever, or difficulty breathing who
received a chest radiograph. A bedside LUS was performed and interpreted by the treating clinician on all children
prior to chest radiograph. The criterion standard was radiographic pneumonia, diagnosed by a panel of radiologists
using the Chest Radiography in Epidemiological Studies methodology. The primary outcome was sensitivity and
specificity of LUS for the diagnosis of pneumonia. All LUS images were later reviewed and interpreted by a blinded
expert sonographer.
Results Three hundred and sixty-six children were enrolled in the study. The median age was 16.5 months (IQR 22)
and 57.3% were male. Eighty-four patients (23%) were diagnosed with pneumonia by chest X-ray. Sensitivity, specific-
ity, positive and negative likelihood ratios for clinician’s LUS interpretation was 89.3% (95% CI 81–95), 86.1% (95%CI
82–90), 6.4, and 0.12 respectively. LUS demonstrated good diagnostic accuracy for pneumonia with an area under
the curve of 0.88 (95% CI 0.83–0.92). Interrater agreement between clinician and expert ultrasound interpretation was
excellent (k = 0.85).
Conclusion Bedside LUS when used by ED clinicians had good accuracy for diagnosis of pneumonia in children in a
resource-limited setting.
