The Effect of Preoperative Ferric Carboxymaltose Administration on Mortality in Geriatric Hip Fractures

Hip fractures (HF) are the most common and serious pathology affecting the hip and are associated with a high mortality risk in elderly patients. The prevalence of HF is increasing day by day and surgery is often required for its treatment. Perioperative anemia not only hinders the early recovery and rapid rehabilitation of elderly patients, but also adversely increases the need for blood transfusion, prolongs hospital length of stay (HLS) and even increases the risk of death. Although the blood transfusion threshold is restrictive, approximately one or two thirds of elderly patients with hip fracture surgery (HFS) require blood transfusion during hospitalization, and blood transfusion also has potential side effects.The most important factor in the development of anemia in HF is blood loss; however, there are other mechanisms (renal failure, inflammation, iatrogenic hemodilution) that lead to the selection of different therapeutic approaches.Oral or intravenous iron supplementation is a well-accepted alternative to counteract or prevent perioperative anemia, stimulate erythropoiesis and increase Hgb level in elderly patients. However, there are few studies addressing the relationship between iron therapy and clinical outcomes or mortality. Because ferric carboxymaltose (FCM) allows doses of 2 g in a single session (and can be administered by a short IV infusion of 15-20 minutes), and furthermore, FCM is excellently tolerated and safe for patients. This study was planned to investigate the relationship between FCM supplementation and blood transfusion volume, HLS, postoperative infection and mortality.

In the prospective randomized controlled study, a 6 - 12 month follow-up of participants undergoing hip fracture surgery with and without preoperative FCM treatment will be performed. Planning is being made with a total of 200 participants from 100 participants each in the experimental and control groups. Participants over the age of 65 who are diagnosed with hip fracture at Istanbul University Istanbul Faculty of Medicine Orthopedics and Traumatology Clinic will be included in the study. Participants who meet the inclusion criteria will be randomized into 2 groups as participants with and without preopaerative FCM (20 min iv infusion) so as to evaluate laboratory values during hospital stay, perop and postop ES transfusion needs, post-discharge 6th week Hgb value and 6th and 12th month mortality information. The parameters to be examined in clinical controls in the study are age, gender, smoking, comorbidities if any, hip fracture type, surgical treatment, ASA score, body mass index, preop/postop/pre-discharge/6th week Hgb value, perop/postop transfusion amount, preop INR value and 6th month/12th month mortality status.
