Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Ferinject ® (Ferric carboxymaltose)
1000mg in 50mL 0.9% sodium chloride
One time intravenous infusion between one and four weeks prior to surgery
Intravenous Infusion
Infusions will be administered at the time of enrolment and attendance at physiological testing. This timing will be dictated by the timing of referral to the Anaesthesia Preoperative Clinic and performance of screening bloods. Treatment will occur as soon as possible after this attendance
Intervention code [1] 316632 0
Treatment: Drugs
Comparator / control treatment
Placebo
1000mg in 50mL 0.9% sodium chloride (the placebo infusion will contain normal saline only and will be administered in opaque syringes and giving sets to mask its contents).
One time intravenous infusion between one and four weeks prior to surgery
Intravenous Infusion
This timing will be dictated by the timing of referral to the Anaesthesia Preoperative Clinic and performance of screening bloods. Treatment will occur as soon as possible after this attendance

Timepoint [1] 322628 0
Six patients per month over a 12 month recruitment period
Primary outcome [2] 322629 0
Feasibility of Research Protocol-patient acceptability. Acceptability will be defined by participation in and completion of the full protocol.

Secondary outcome [1] 379097 0
Change in haemogloblin- as part of full blood count; automated analyser or haemoglobinometer. Most methods based on spectrophotometry.

Admission
Secondary outcome [6] 379102 0
Cost Effectiveness-hospitalisation costs will be calculated using a bottom up approach. These data will be sourced from the health service clinical costing system which captures episode-level costs categorised into relevant cost buckets. These costs will be collected for the relevant admission and any re-admissions within 30 days post discharge.
Timepoint [6] 379102 0
Admission and any re-admissions within 30 days post discharge
Secondary outcome [7] 379677 0
Change in reticulocytes-assessed by fresh blood incubated with:
1. supravital stain for ribosomal RNA and examined by microscopy; or
2. fluorescent dye taken up by RNA and cells counted by flow cytometry.

Most current haematology analysers have reticulocyte modules to perform semi-automated or automated reticulocyte counts. Principle of test depends on the specific instrument.

The absolute reticulocyte count is calculated from the reticulocyte percentage and the red cell count.
Timepoint [7] 379677 0

Secondary outcome [8] 379678 0
Change in iron stores-assessed by immunoassay
Timepoint [8] 379678 0
At admission and 30 days post-operative
