Laura Diegelmann, MD, RDMS, was a site coordinator for an international study on the use of ultrasound in the assessment of nontrauma patients with hypotension without an obvious cause. The study involved patients from three medical centers in North America and three in South Africa. Point-of-care ultrasound conveyed no demonstrable outcome benefit to patients with undifferentiated shock. The results of this study were published as the article titled “Does Point-of-Care Ultrasonography Improve Clinical Outcomes in Emergency Department Patients with Undifferentiated Hypotension? An International Randomized Controlled Trial from the Shoc-ED Investigators” in the October issue of Annals of Emergency Medicine.
