ObjectivesThree are no clinical practice guidelines that specifically address the management of patients with iron deficiency anemia (IDA) in the emergency department (ED). The goal of this study was to describe the characteristics of IDA patients who present to the ED, documentation of IDA by emergency physicians, utilization of iron supplementation, and the appropriateness of red blood cell (RBC) transfusions ordered in the ED.MethodsA retrospective medical chart review was performed of IDA patients who visited the ED of a large tertiary center over a three-month period. Appropriateness of RBC transfusion was determined using a novel algorithm developed by our institution.ResultsOver the study period, there was a 0.3% (49/14,394) prevalence of IDA in the ED. In thirty (30/49; 61%) patients, IDA was documented by an emergency physician. RBC transfusions were administered to 19 patients; 10 transfusions (53%) were appropriate, 3 (16%) were appropriate for indication, but more than the required number of units were ordered, and 6 (32%) were inappropriate. Of the patients discharged, one (1/25; 4%) patient received intravenous iron in the ED and 6 of the 11 patients (55%) that were not already taking oral iron received a prescription at discharge from the ED.ConclusionsThis assessment demonstrated that management of IDA patients presenting to the ED may represent an important knowledge-to-practice gap. It revealed that RBC transfusion may be over-utilized and could be replaced by safer, lower-cost alternatives such as intravenous and oral iron. Guidelines for management of IDA in the ED may be necessary to achieve consistent IDA management and avoid inappropriate use of RBC transfusion.
