Incidence of Acute Kidney Injury After Exposure to Intravenous Contrast in Emergency Department Patients Presenting for Stroke.

Background: Chronic kidney disease (CKD) is to be considered an independent risk factor for developing post-computed tomography (CT) acute kidney injury (AKI); however, current data are limited.

Objectives: Examine the incidence of AKI after intravenous contrast exposure among patients with and without CKD.

Methods: A single-center retrospective study examined patients that presented to the Emergency Department and activated the stroke protocol, which involved an immediate CT angiogram.

Costs and Consequences of a Novel Emergency Department Sepsis Diagnostic Test: The IntelliSep Index.

Unlabelled: Sepsis causes 270,000 deaths and costs $38 billion annually in the United States. Most cases of sepsis present in the emergency department (ED), where rapid diagnosis remains challenging. The IntelliSep Index (ISI) is a novel diagnostic test that analyzes characteristics of WBC structure and provides a reliable early signal for sepsis.
