Gravel CA, et al. - Researchers investigated interrater reliability (IRR) of lung point-of-care ultrasound (POCUS) findings among a convenience sample of patients aged 6 months to 18 years with a clinical suspicion of pneumonia. These patients had a lung ultrasound performed by a POCUS-credentialed emergency medicine physician with subsequent expert review. Outcomes suggested that, for assessing these pediatric patients, lung POCUS findings had moderate interrater reliability. They noted that B-lines were most reliable. Overall, they advised that additional assessment of lung POCUS may be necessary to conduct proper training and optimal scanning techniques to ensure adequate reliability of ultrasound findings in the assessment of pediatric pneumonia.
