Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients that meet the inclusion criteria will be approached to join the trial and informed consent will be taken. Pateints will then be randomised to either treatment or control groups. This allocation will be kept in hospital pharmacy with access to unblinding information always available via the on-call pharmacist. The patients will be allocated by way of sequentially numbered opaque envelopes with the envelope giving the participant their unique trial number and their group allocation. The patients’ unique medical record number (UMRN) will be linked to their trial number by means of a trial register kept in a locked filing cabinet in each hospital.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
1:1 allocation to placebo or treatment groups.
by a computer generated algorithm

Other reasons/comments
Other reasons
Observed reduction in transfusion rates in this patient population (>35% to <20% over the study recruiting period) means the endpoint the study is powered for (reduction in transfusion rates) has occurred independent of the study intervention.
Further, changes to patient consent and recruitment ability in WA for those patients without capacity made the study unachievable.

Summary
Brief summary
As the population ages there is an increasing number of elderly patients presenting to hospital with fractured hips. A large proportion of these patients receive blood transfusions, a treatment that is associated a significant cost and potential harm. Most of these patients being transfused have an iron deficiency anaemia. We plan to examine the benefit of giving intravenous iron to these patients to see if we can reduce the number needing a blood transfusion and improve nadir haemoglobin and ultimately reduce length of stay and 6 month mortality
