Is perioperative blood transfusion a risk factor for mortality or infection after hip fracture?
OBJECTIVES: To assess whether allogeneic blood transfusion in the perioperative period is associated with changes in mortality or complication rates in patients undergoing surgical treatment for hip fracture (proximal femoral fracture). DESIGN: Retrospective case-control series, all patients followed up for 1 year or until death. SETTING: District General Hospital in Peterborough, UK. PATIENTS PARTICIPANTS: Three thousand six hundred twenty-five consecutive patients admitted and operated for hip fracture (proximal femoral fracture) during July 1989 to January 2002 (151 months); 1068 (29.9%) received a perioperative allogeneic blood transfusion. MAIN OUTCOME MEASURES: Thirty- 120-, and 365-day mortality, deep and superficial wound infection rates. RESULTS: Overall mortality for all patients at 1 year post fracture was 28.2% (1007 patients). Transfusion was associated with a statistically significant increase in mortality from 120 days onward after hip fracture. However, when this was ad
