Improving Safety and Quality During Interhospital Transfer of Patients With Nontraumatic Intracranial Hemorrhage: A Simulation-Based Pilot Program.

J Patient Saf 2021 Apr 14. Epub 2021 Apr 14.

From the Yale School of Medicine Yale New Haven Health, New Haven, Connecticut.

Background: The presentation of critically ill patients to emergency departments often necessitates interhospital transfer (IHT) to a tertiary care center for specialized neurocritical care. Patients with nontraumatic intracranial hemorrhage represent a critically ill population subject to high rates of IHT and who is thus an important target for research and quality improvement of IHT. We describe the use of an innovative simulation methodology engaging transfer staff, clinicians, and stakeholders to refine and facilitate the adoption of a standardized IHT protocol for transferring patients with neurovascular emergencies.

A Four-Week-Old Infant With Respiratory Distress: An Emergency Department Case Presentation of Congenital Lobar Emphysema.

Cureus 2021 Mar 10;13(3):e13814. Epub 2021 Mar 10.

Emergency Medicine, Stanford University, Stanford, USA.

Congenital lobar emphysema (CLE) and congenital pulmonary lymphangiectasis (CPL) are rare conditions that are most often identified with prenatal ultrasonography. Occasionally, this disease process is first identified in the emergency department (ED), where the physician should avoid common pitfalls in order to prevent acute decompensation. To the best of our knowledge, there are no prior reports in the emergency medicine literature of CLE or CPL presenting to the ED as undifferentiated respiratory distress in an infant. Read More
