Description of intervention(s) / exposure
Patients with post-operative anaemia will be randomised between standard care after surgery and a single iron carboxymaltose infusion 15mg/Kg body weight once only infused over 15 minutes within 24-48 hours post-operatively.

Intervention code [1] 290655 0
Treatment: Drugs
Comparator / control treatment
1. Age and sex matched postoperative patients with normal iron stores/Hb postoperatively who receive routine postoperative care after their consent.
2. Patients with post-operative anaemia allocated to the control group receive standard care, which is defined as management of postoperative anaemia with blood transfusion according to hospital guidelines.
Control group
Active

Patients who undergoing elective surgery with Hb >120 g/L will serve as control group.
Minimum age
18 Years
Maximum age
No limit

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This study is to assess the effect of intravenous single iron therapy versus standard care for patients after surgery in the Launceston General Hospital. Patients who receive the standard care and not eligible for the study will be also followed up to assess their outcomes with their consent. The study will be explained in detail to the patients mainly preoperatively, and if necessary postoperatively and a written informed consent will be obtained from all subjects prior to their enrolment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A full patient profile will be obtained including medical and drug history, usual diet and exercise regime. The patient’s demographic and physical detail (weight, height etc) will be measured and recorded.

Eligible patients for the trial will be counselled on any side effects from the iron and ensured that if they decide to withdraw from the study at any time this will in no way affect their care or procedure at the LGH.

The patients will be randomized by an impartial party in the Pharmacy Department to avoid any possible bias using a randomly assigned computed system. The research assistant at enrolment will use the random assigned number schedule issued by the pharmacy. Patients will be randomized initially to 1) intravenous iron or 2) standard care.

Type of endpoint/s
Efficacy
Statistical methods / analysis
The primary end points will be Hb, iron studies levels at discharge, amount of transfused blood, lenghth of stay at the hospital. The study design is a randomised controlled trial with two-way randomisation. Multivariable analyses will be conducted to compare the outcomes in the two treatment groups, unadjusted and adjusted for actual and potential confounding variables (e.g. age, gender, initial Hb, and operation site, body weight, final post-operative Hb where relevant): post-operative Hb and ferritin levels by repeated measures ANOVA using general linear modelling; peri-operative blood transfusion volumes by Poisson regression.

It is estimated that we would screen about 1000-2000 patients over an 18-24 month period, and that 10% of these would fit the inclusion criteria. Sample size calculations indicate a requirement for 52 completed patients per treatment group for both outcomes based on assumptions: i) a minimum effect size detection of 2g/l increase in postoperative Hb and a 45% reduction in units of blood transfused; ii) an untreated rise in Hb of 0g/l and SD 2.8g/l, and an expected untreated transfusion rate of 2.2 units per patient SD 1.8g/l (data from ‘Iron pre-load for major joint replacement’ Transfusion Medicine 1997; 7: 281-6); iii) alpha value of 0.05 and power of 80% allowing drop-out and missing data. A minimum effect size reduction of 36% in transfusion rate would require 100 patients per group (200 in total).
