OBJECTIVES: It is still under debate that red blood cell (RBC) transfusions might increase the risk of healthcare-associated infections after hip fracture surgery. Previously, we found that a liberal RBC transfusion strategy improved survival in nursing home residents. Our aim, therefore, was to investigate whether a more liberal RBC transfusion strategy was associated with a higher infection risk in frail elderly hip fracture patients. DESIGN: Prospective, assessor-blinded, randomized and controlled trial. SETTINGS: Orthopedic ward, Geriatric ward, and Hospital-at-home. PATIENTS: 284 consecutively hospital-admitted elderly with hip fracture from nursing homes or sheltered housing facilities were included. INTERVENTION: A restrictive RBC transfusion strategy (hemoglobin <9.7 g/dL; 6 mmol/L) compared with a liberal strategy (hemoglobin <11.3 g/dL; 7 mmol/L) administered within 30 days after surgery. MAIN OUTCOME MEASUREMENTS: Leukocytes and C-reactive protein (CRP) in repeated blood samples within 30 days, and number of all infections (pneumonia, urinary tract infection, and other infections) within 10 days. RESULTS: 88 % of the patients received a RBC transfusion. A median of 1 RBC unit (interquartile range (IQR): 1-2) was transfused for the restrictive strategy group versus 3 RBC units (IQR: 2-5) for the liberal group. Leukocytes and CRP measurements were similar for both groups. Rates of infection were 72 % for the restrictive group compared to 66 % for the liberal group (risk ratio 1.08; 95 % confidence interval 0.93-1.27, p value 0.29). CONCLUSIONS: A more liberal RBC transfusion strategy was not associated with higher risk of infection among residents from nursing homes or sheltered housing undergoing hip fracture surgery.
