Michael D. Johnson, MD

  • Dr. Johnson completed his medical degree at the Medical College of Wisconsin in Milwaukee, WI. He then completed his residency in pediatrics at the Mayo Clinic in Rochester, MN. He is currently an Associate Professor in the Division of Pediatric Emergency Medicine at the University of Utah.

    Dr. Johnson´s clinical interests include improving the efficiency and effectiveness of patient care in the Emergency Department and Rapid Treatment Unit at Primary Children's Hospital and across the Intermountain Health system, especially the care of children with respiratory illness including asthma and bronchiolitis. He serves as the representative of the Primary Children's Hospital EmergencyDepartment for hospital and system-wide work groups tasked with improving respiratory care.

    His research focuses on optimizing the care provided to children with severe acute asthma in the emergency department. Currently this work is centered on understanding the effectiveness of intravenous magnesium sulfate for children who are likely to be hospitalized despite other treatment in the emergency department. He works with pediatric emergency medicine physicians and researchers across the United States as a member of the steering committee for the Pediatric Emergency Care Applied Research Network (PECARN) and across the world as a participant in the Pediatric Emergency Research Networks (PERN) to conduct research that improves the lives of children no matter where they seek emergency care.

    Dr. Johnson sees patients at Primary Children’s Hospital Emergency Department and Rapid Treatment Unit.
