Overview

Retrospective cohort study examines IV iron use and outcomes in emergency department patients with anemia, highlighting clinical implications.

Key Points

  • This study aims to describe the usage of intravenous iron therapy and red blood cell transfusion patterns in emergency department patients with anemia.
  • Conducted a single-center retrospective cohort study from January 2019 to December 2021.
  • Included patients with hemoglobin levels ≤ 10 g/dL.
  • Compared baseline characteristics, transfusion practices, and clinical outcomes between IV iron recipients and non-recipients.
  • Only 2.7% of patients (89 out of 3340) received IV iron in the ED.
  • IV iron recipients had a higher incidence of gastrointestinal disorders (68.5% vs. 19.9%) and more ED transfusions (69.7% vs. 11.1%).
  • Median hospital length of stay was shorter for IV iron recipients (6.6 days) compared to non-recipients (9.7 days).
