About this study
to investigate prevalence of agreement between sonographic and clinical diagnosis in adult patients seen in an emergency department.
Read the detailed description
Point-of-care ultrasound (POCUS) can improve patient management in the emergency department (ED). However, previous studies have focused only on selected groups of patients, such as trauma, shock, dyspnea, or critically ill patients, or patients with an already known diagnosis. Most patients seen in the ED do not match these criteria. This study aims to investigate prevalence of agreement between sonographic and clinical diagnosis in adult patients seen in an emergency department.
