Primary outcomePrimary: Percentage of Participants For Whom CXR Was Not Needed to Diagnose Pneumonia — 38.8; 0 percentage of participants
Summary
The primary objective of this study is to determine if lung ultrasound (LUS) can replace chest x-ray (CXR) when evaluating patients with possible pneumonia. Specifically, we are looking for an overall reduction of CXR when LUS is used first. Our null hypothesis is that LUS cannot replace CXR for diagnosing pneumonia. Our alternate hypothesis is that LUS can replace CXR for diagnosing pneumonia. Our secondary objectives include: (1) a comparison of unscheduled healthcare visits after the index Emergency Department (ED) visit between those subjects who undergo CXR first and those who undergo LUS first, (2) an evaluation of the rate of antibiotic use between the two groups, (3) a comparison of the admission rates, and (4) a comparison of the length of stay in the Emergency Department between the two groups.
