The primary aim of this clinical trial is to investigate the effects of intravenous iron on recovery in mobility compared to the pre-fracture level in patients with a hip fracture
The main questions it aims to answer are:
It is hypothesize that intravenous iron will enhance gains in mobility and hereby recovery of mobility, increase hemoglobin (Hgb), lower fatigue, have a positive effect on skeletal muscles in the weeks and months after administration.
The primary objective is to compare the effect of a single dose of ferric derisomaltose (FDI) (20 mg/kg body weight) relative to placebo on patients' recovery of functional mobility, measured as the change from baseline in the New Mobility Score.
Participants will:
- Receive either a single dose of intravenous FDI (20 mg/kg body weight) (and saline) or placebo (saline) at 1-5 days after surgery.
This trial will be conducted at three hospitals in Denmark, involving an anticipated 210 participants.

| A. Cost-effectiveness analysis | Explorative outcome A: Cost-effectiveness analysis will be made from a societal perspective including cost of FDI, hospital bed days, readmissions, outpatient visits and costs related to lost productivity of the patients (production loss). The analysis will be done according to the guidelines for health economic evaluation. The analysis will be based on data from the electronic patient records and data on the duration of patient's sick leave and absence from work from patient surveys. The main results from the analysis will be a comparison of the mean costs per patient in the intervention and the control group, the mean change in Quality Adjusted Life Years gained in the two groups (based on EQ5D) and the incremental cost-effectives ratio. |
