Introduction: Hip fractures are common injuries with high morbidity and mortality rates. These patients often become anemic and require allogenic blood transfusion. Transfusions are costly with potential complications. This study examines the effect of intravenous (IV) iron on patients with hip fractures, undergoing surgery within 48 hours, and being treated with a highly restrictive transfusion protocol. Materials and Methods: A retrospective chart review performed on patients admitted to a level 1 tertiary care center with fractures of the proximal femur from December 2015 to December 2017 included 239 patients. Patients who received 300 mg of IV iron when their hemoglobin fell below 11 g/dL were compared to a control group of patients who never received IV iron with respect to transfusion rate, 30-day readmission rate, nosocomial infections, length of stay, and hospital costs. Results: There were no significant differences in transfusion rates ( P = .118). There was a trend toward decreased length of stay ( P = .063) and 30-day readmission rates ( P = .051) with a 59% reduction in the odds of 30-day readmission when a patient received IV iron. There were no differences in nosocomial infection rates or cost of hospitalization. Discussion: This study presents a compelling argument for further research regarding the use of IV iron in elderly patients undergoing surgery for a hip fracture. Length of stay and transfusion rates are increased in patients with intertrochanteric fractures and undergoing intramedullary nailing. A higher number of these patients in the IV iron group may have falsely increased these rates. A prospective, randomized, controlled trial is needed to assess the true effects of perioperative IV iron. Conclusions: This study showed no significant benefit to IV iron use in elderly patients undergoing surgical treatment of hip fracture. The decrease in 30-day readmission rate should be further examined with a prospective randomized controlled trial.
