To help reduce the spread of infection, our radiologists and radiologic technologists at the University of Utah Health are taking chest X-ray (CXR) images of suspected COVID-19 patients through a glass partition. In addition to minimizing the spread of COVID-19, the innovative technique also helps us conserve precious Personal Protective Equipment (PPE).
Suspected COVID-19 patients are placed comfortably and safely in negative pressure observation rooms. Then our staff captures the chest X-ray images through a glass wall of the room, using Carestream’s portable DRX-Revolution X-ray unit. (Scroll to bottom of page for instructional video.)
“With some minor technical modifications, chest X-rays taken through the glass are just as clear as normal X-rays,” states Phuong-Anh Duong, MD, Associate Professor of Radiology. Duong, along with her colleagues in the Cardiothoracic Imaging Section, Joyce Schroeder, MD (Section Chief), and Howard Mann, MD, brought the idea to Alex Nieves, MPA, the Manager of Diagnostic Radiology services at the hospital. Together, they tested the new setup and were pleased with the results.
Normally, inpatients are taken to our X-ray rooms where technologists interact with them directly, positioning them and obtain the images. Even in the Emergency Department, our portable DRX-Revolution X-ray machines are brought into the rooms, and once again staff position the patients so that the images can be obtained correctly.
With the advent of the COVID-19 pandemic, University Hospital policy is that any patient who comes to the hospital struggling with respiratory symptoms is treated as a suspected COVID-19 infection. These patients are taken directly to the Emergency Care Unit (separate, negative-pressure rooms from standard ED rooms). The goal is to minimize contact between these patients and the rest of the hospital, including care providers.
Taking a chest X-ray is one of the first tests done for patients with respiratory distress. “This technique minimizes hallway traffic for patients and staff, which greatly decreases the risk for transmitting COVID-19,” explains Nieves. What’s more, with concerns over PPE being scarce across the country (although this is not a concern in Utah at the moment), our staff do not have to use a set of masks, goggles, and gloves in order to take these X-rays because they do not need to enter the room. This saves time, exposure risk, and cost of materials needed for PPE and sanitization of equipment. “We’re using this technique every day,” notes Nieves.
Dr. Mann was first made aware of this technique from colleagues at the University of Washington Medical Center who began experimenting with it at the end of March. He brought it to our team and we quickly followed suit. We are working on refining the technique, providing training for nurses who will help with the positioning, and studying the effectiveness of this technique in reducing the contact between sick patients and radiology personnel and equipment.
“We are trying to do our part to be as innovative as possible in meeting this ever-changing situation,” notes Satoshi Minoshima, MD, PhD, the Anne G. Osborn Chair of Radiology and Imaging Sciences. “We don’t know how long this situation might last and finding ways to safely treat patients and conserve PPE is paramount,” he adds.
