OBJECTIVE: To explore current recommendations for intravenous (IV) iron use in clinical guidelines for iron deficiency anemia (IDA) across different therapeutic areas and identify recommendations, if any, for the treatment of IDA. METHODS: A literature search was conducted in Medline, EMBASE, BIOSIS, Cochrane Collaboration, and on websites of relevant professional associations. Searches were limited to English publications. 1292 citations were identified, 219 papers were assessed, and 35 guidelines were identified for inclusion. RESULTS: The guidelines covered a variety of geographies: United States (US; n = 10); Europe (n = 11); "Rest-of-World" (n = 9); and "Other" organizations (n = 5). These covered a variety of specialties. Guidelines defined iron deficiency and IDA generally by serum ferritin and transferrin saturation levels. One-fifth of the reviewed guidelines (7 of 35) included no mention or recommendation regarding parenteral iron's utility in the management of IDA. Fifteen guidelines recommended using parenteral iron in the management of IDA. Fewer US guidelines included recommendations around IV iron than in Europe or the rest of the world. Approximately 60% of the guidelines have not been updated in ≥5 years and consequently do not reflect current evidence on the safety and efficacy of IV iron. CONCLUSIONS: While national and international guidelines for management of IDA exist, many are outdated and do not reflect current evidence including, but not limited to, parenteral iron use. Urgent consideration should be given to updating and clarifying management guidelines for IDA using the latest treatment modalities and options, particularly in the US.
