Perioperative intravenous iron to treat patients with fractured hip surgery: A systematic review and meta‐analysis

Abstract

Background: Treatment of preoperative anemia with intravenous iron is common within elective surgical care pathways. It is plausible that this treatment may improve care for people with hip fractures many of whom are anemic because of pre-existing conditions, fractures, and surgery. Objective: To review the evidence for intravenous iron administration on outcomes after hip fracture. Design: We followed a predefined protocol and conducted a systematic review and meta-analysis of the use of intravenous iron to treat anemia before and after emergency hip fracture surgery. The planned primary outcome was a difference in length of stay between those treated with intravenous iron and the control group. Other outcomes analyzed were 30-day mortality, requirement for blood transfusion, changes in quality of life, and hemoglobin concentration on discharge from the hospital. Data Sources: EMBASE, MEDLINE, The Cochrane Library (CENTRAL, DARE) databases, Clinicaltrials.gov, and ISRCTN trial registries. Date of final search March 2022. Eligibility Criteria: Adult patients undergoing urgent surgery for hip fracture. Studies considered patients who received intravenous iron and were compared with a control group. Results: < 0.01) in the analyzed RCTs. Functional outcomes and quality of life were variably reported in three studies. Conclusion: The evidence on the use of intravenous iron in patients with hip fracture is low quality and shows no difference in length of acute hospital stay and transfusion requirements in this population. Improved large, multicentre, high-quality studies with patient-centered outcomes will be required to evaluate the clinical and cost-effectiveness of this treatment.
