BACKGROUND Primary total hip arthroplasty (THA) often requires blood transfusion. Transfusions are undesirable due to risks of infectious and noninfectious complications. This systematic review therefore studied the effectiveness of erythropoietin (EPO) in reducing allogeneic transfusion rate during THA. METHODS Using the MESH terms "Erythropoietin" AND "Total Hip" with restrictions to 'Randomized Controlled Trial', 'Clinical Trial', 'Humans', and 'English', a literature search was performed in PubMed and CINAHL. Articles were scanned by both authors and retained for further review if eligibility was met according to the inclusion criteria defined by the PICOS (population, intervention, comparator, outcomes, study design) configuration. Risk of bias was assessed using the Cochrane risk of bias criteria. Data extracted include patient demographics, intervention versus comparator arm, outcomes, laboratory data, and individual study characteristics. The primary outcome of focus was rate or amount of allogeneic blood transfusions intra- or postoperatively. In 6/8 studies, data permitted calculations of absolute risk reduction (ARR) in transfusion rate (%) and number needed to treat (NNT) to evade transfusions. RESULTS A total of 8 studies met all eligibility criteria and were retained for data extraction; risk of bias was low-moderate in 7/8 and high in 1/8. Allogeneic transfusion exposure was lowered by the intervention in 7/8 studies with ARR from 9.6% to 33.5% and NNT from 4 to 10. CONCLUSIONS In the blood conservation systems described, the addition of EPO was effective in reducing allogeneic transfusions. The studies included spanned a nearly 30-year period. Earlier studies incorporated preoperative autologous donation, a now outdated modality.
