About this trial
Anemia is a frequent complication of gastrointestinal bleeding, affecting 61% of the patients. Currently, anemia caused by gastrointestinal bleeding can be treated with iron supplementation. However, the dose and route of the administration are still a question. The FIERCE clinical trial aims to compare the effect of intravenous iron supplementation and oral iron replacement on mortality, unplanned emergency visits, and hospital readmissions in multimorbid patients with acute nonvariceal gastrointestinal bleeding.
