Elderly with hip fractures are often frail and discharged from hospital after few days of hospitalisation. Hip fracture surgery is often associated with blood loss, where the patient is at risk of developing anaemia. Low haemoglobin level reduces the body's oxygen transport which causes impaired functional ability and strain on vital organs. Acute anaemia is worse tolerated in elderly, than in younger patients. Therefore this study aims to investigate whether there are effects of an expanded indication for blood transfusion in the frail elderly.
