Delayed Management of Necrotizing Soft Tissue Infection – Who does the Patient Belong To?

Tanya Rinderknecht, MD and Garth Utter MD, MSc| April 29, 2020

Save to Library

A 52-year old women presented to the emergency department with a necrotizing soft tissue infection (necrotizing fasciitis) after undergoing cosmetic abdominoplasty (‘tummy tuck’) elsewhere.

The Safety Challenges of Supervision and Night Coverage in Academic Residency

Katie Raffel, MD| October 30, 2019

Save to Library

An intern night float, called in on jeopardy from an outside institution for an intern who was ill, was paged to the bedside of an unstable patient to assess his condition. In the electronic health record, the intern checked the code status and clinical information, but the signout did not specify the patient’s goals of care nor what course of action to take should the patient worsen. Although the patient was listed as full code and the intern attempted to reach both the rapid response team and the senior resident, she was not aware the pager numbers were incorrect. Eventually, the intern flagged a senior resident passing in the hallway, who assessed the patient and suggested they contact his family.

Spotlight: Mistaken Attribution, Diagnostic Misstep

Timothy R. Kreider, MD, PhD, and John Q. Young, MD, MPP, PhD| January 1, 2019

Save to Library

A woman with a history of psychiatric illness presented to the emergency department with agitation, hallucinations, tachycardia, and transient hypoxia. The consulting psychiatric resident attributed the tachycardia and hypoxia to her underlying agitation and admitted her to an inpatient psychiatric facility. Over the next few days, her tachycardia persisted and continued to be attributed to her psychiatric disease. On hospital day 5, the patient was found unresponsive and febrile, with worsening tachycardia, tachypnea, and hypoxia; she had diffuse myoclonus and increased muscle tone. She was transferred to the ICU of the hospital, where a chest CT scan revealed bilateral pulmonary emboli (explaining the tachycardia and hypoxia), and clinicians also diagnosed neuroleptic malignant syndrome (a rare and life-threatening reaction to some psychiatric medications).
