Aims This study assesses the effect of hip fracture anatomy and operation performed on transfusion rates within our centre. We aim to identify patients most likely to require transfusion early, to improve outcomes. Methods A retrospective cohort study of 324 consecutive hip fracture patients presenting to a district general hospital over one year. Data was collected from patient records, local transfusion laboratory and the national hip fracture database. Results 324 hip fractures were categorised as 188 (58%) intracapsular, 121 (37%) intertrochanteric and 15 (5%) subtrochanteric fractures. The most common operation performed was hemiarthroplasty (128), followed by dynamic hip screw fixation (75). 75 (23%) patients received a blood transfusion. 15% of intracapsular, 35% of intertrochanteric and 33% of subtrochanteric fractures received transfusions. 47% of long intramedullary nails, 45% of short intramedullary nails, 29% of dynamic hip screws, 18% of hemiarthroplasties and 9% of total hip arthroplasties resulted in blood transfusions. One-year mortality was higher in the transfused cohort at 52% compared to 30.5% in non-transfused, with an odds ratio of 2.466 (95% CI 1.4555 to 4.178, p = 0.0008). Conclusions Almost a quarter of hip fracture patients received a blood transfusion, which was associated with an almost two and a half times increased risk of one-year mortality. Extracapsular (intertrochanteric and subtrochanteric) fractures most commonly led to transfusions. Long intramedullary nailings were most associated with transfusions and total hip arthroplasties the least. Patients more likely to require transfusion and subsequently have a higher one-year mortality risk can therefore be identified at presentation.
