Victoria General Hospital medical records, the transfusion services record and the Dalhousie University Hip Study databases were integrated and analyzed using a standard statistical package.Results: The incidence of infection postoperative was 9.9% overall, 8.4% in patients receiving no transfusion, and 14% in those receiving homologous transfusion (p = 0.035). There were no infections in the 11 patients who received an autologous blood transfusion. Significant predictors of postoperative infection were sex, age and duration of surgery; these were not confounding variables (χ2 multivariate analysis). Neither the operating surgeon nor the blood product transfused affected the infection rate.Conclusions: These findings suggest an increased risk of postoperative infection in patients who undergo primary hip replacement and receive homologous blood transfusions perioperatively.
