Brief summary
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.
Interventions
The active intervention is a single dose of Ferric Derisomaltose, 20mg/kg body weight, diluted in 100 mL isotonic sodium chloride 0.9%
DRUGSaline (NaCl 0,9 %) (placebo)
Single dose of 100 mL isotonic sodium chloride 0.9%

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| New Mobility Score (NMS) | Measured as the change from baseline (reported as pre-fracture NMS) in the New Mobility Score after 4, 6 and 12 weeks | The primary outcome is to compare the effect of a single dose of FDI (20 mg/kg body weight) relative to placebo on patients' recovery of functional mobility measured with New Mobility Score. New Mobility Score is a validated patient reported outcome measurement 0-9-point score for hip fracture patients, with 9 point equal to a fully independent indoor, outdoor and during shopping walking ability and 0 point, indicating no walking ability. Higher scores indicate a better outcome. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Hemoglobin | Measured at baseline, 6 and 12 weeks after intervention. | — |
| Red blood cell transfusion requirement | Measured on postoperative day (POD) 7 and POD 30 | This will be measured by the proportion of patients who receive at least one red blood cell unit and the amounts of units per patient |
| Fatigue, assessed using the Verbal Rating Scale for Fatigue (F-VRS) | Measured at baseline, 4, 6 and 12 weeks after intervention. | Fatigue will be assessed using the Verbal Rating Scale for Fatigue (F-VRS). This scale, ranging from 0 to 4, measures fatigue in hip fracture patients, where 0 indicates no fatigue and 4 represents extreme fatigue. |
| Quality of life with EuroQol 5-Dimension 5-Level questionnaire (EQ-5D-5L ) | Measured as a retrograde baseline the weeks prior to admission and at 6 and 12 weeks after intervention | The EQ-5D-5L questionnaire measures health-related quality of life across five dimensions, with scores ranging from 1 (no problems) to 5 (extreme problems). Higher scores indicate worse outcomes, reflecting greater health issues. |
| EuroQol Visual Analogue Scale (EQ VAS 0-100) | Measured as a retrograde baseline the weeks prior to admission and at 6 and 12 weeks after intervention | The EQ VAS 0-100 (range) is a visual analogue scale where 0 represents the worst imaginable health state and 100 represents the best. Higher scores on the EQ VAS indicate a better health outcome. |
| Fear of falls measured with, Short Falls Efficacy Scale International (Short-FES-I) | Measured at baseline and at 6 and 12 weeks after intervention. | Short Falls Efficacy Scale International (Short-FES-I) measures concern about falling during various activities, with scores ranging from 7 (no concern about falling) to 28 (severe concern about falling). Higher scores indicate greater concern about falling. |
| 30 second Sit-to-Stand-Test (STS) | Measured at baseline, 6 and 12 weeks | Participants are encouraged to stand and fully sit as many times as possible within 30 seconds, with correct form monitored by the tester. If a participant uses their arms, they score a 0, and only correctly executed stands are counted. This test assesses a wide range of ability levels. Lower score indicates worse outcome. |
| Activity of daily living, asessed with Barthel Index 20 | Measured as a retrograde baseline and at 6 and 12 weeks after intervention | Barthel 20 Index measures a patient's level of independence in daily activities, with scores ranging from 0 (complete dependence) to 20 (complete independence). Higher scores indicate a better outcome, reflecting greater independence. |
| Pain, assessed using the Verbal Rating Scale for pain | Measured at baseline and at 6 and 12 weeks after intervention | Hip fracture-related pain will be assessed using the Verbal Rating Scale for Pain, which ranges from 0 to 4. A score of 0 indicates no pain, while a score of 4 represents unbearable or the worst imaginable pain |
| Days alive and at home up to 30 (DAH30) | Measured at 6 weeks after intervention. | The DAH30 is determined using a combination of electronic medical records (obtaining length of stay) and direct participant inquiries at the 6 week follow up |
| Serious adverse event (SAE) | Will be assessed up to the 6 weeks follow up | SAE defined following the ICH - GCP guidelines |
| Mortality | 90 days | The time of death is determined using validated registry-based data, from which survival rates, as well as 30-day and 90-day mortality rates, are calculated. |
