Among children with high suspicion for pneumonia, CXRs infrequently altered the initial plan for antibiotics. However, when clinical suspicion for pneumonia was low, the use of CXR may reduce unnecessary antibiotic use.
The WHO criteria demonstrated poor sensitivity for the diagnosis of radiographic pneumonia in a US-based pediatric emergency department. Compared with respiratory rate, oxygen saturation offered slightly improved test characteristics. Although applied to a different target population, these findings suggest the WHO criteria may not be a sensitive screening tool for the diagnosis of pneumonia in children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
