Plain English summary of protocol

Background and study aims
Patients with anemia (low blood hemoglobin) undergoing orthopedic surgery (e.g. hip or knee replacement) require more blood transfusions. In the Netherlands 70% of hospitals give erythropoietin treatment to this group of patients, but this treatment is expensive. The aim of this study is to find out whether intravenous iron treatment can replace erythropoietin and achieve the same results with lower costs.

Who can participate?
Patients aged over 18 with anemia (low blood hemoglobin) undergoing hip or knee replacements

What does the study involve?
Participants are randomly allocated to be treated with either intravenous iron infusion, erythropoietin, or no intervention (control group). The blood transfusion rates of the three groups are compared.

What are the possible benefits and risks of participating?
Participants may benefit from fewer blood transfusions and a better outcome because of higher hemoglobin levels. Besides very rare side effects of erythropoietin and iron infusions no major risks are expected.

Where is the study run from?
Albert Schweitzer Hospital (Netherlands)

When is the study starting and how long is it expected to run for?
January 2013 to January 2015

Who is funding the study?
Albert Schweitzer Hospital (Netherlands)

Study acronymPOP-i
Study objectivesCan intravenous (i.v.) iron therapy can become a method of blood saving therapy for orthopedic surgery and can it replace erythropoietin?
Ethics approval(s)CCMO Maastad Hospital Rotterdam, Is an official ethics committee, 26/09/2012, nr. NL 35394.101.11. METCnr 2011_18
Health condition(s) or problem(s) studiedOrthopedic surgery
InterventionThree-arm randomised study in patients with a start Hb level > 6,1 and < = 8,1 mmol/l. Intervention groups will be compared with a control group.

The intervention group will receive i.v. iron infusion or Epo.
The control group will receive no intervention.

Both groups will be transfused following the Dutch Transfusion Guideline (4,5,6, Flexinorm).
Intervention typeOther
Primary outcome measure(s)

1. Can ferric carboxymaltose effectively reduce RBC transfusion rate compared to controls in elective orthopedic surgery patients?
2. Rate of transfused patients

Key secondary outcome measure(s)

1. Does i.v. iron therapy increase preoperative Hb-levels and improve postoperative recovery?
2. Is this i.v. iron therapy also efficient for patients with anemia other than iron deficiency (ACD)?
3. Is infusion of i.v. iron policlinically safe?
4. Cost reductions caused by introduction of i.v. iron therapy - can it then replace Epo?
5. Hospital stay
6. Postoperative complications
7. Time needed for revalidation
8. Measurement of quality of life
9. Total cost treatment
10. Hb-levels pre- and postoperatively
11. Amount of RBC per patient
12. Safety of IV iron
