Aims

To determine if patient ethnicity among patients with a hip fracture influences the type of fracture, surgical care, and outcome.

We performed a retrospective study of a departmental database to assess the efficacy of a new model of orthopaedic care on the outcome of patients with a fracture of the proximal femur. All 1578 patients admitted to a university teaching hospital with a fracture of the proximal femur between December 2007 and December 2009 were included. The allocation of Foundation doctors years 1 and 2 was restructured from individual teams covering several wards to pairs covering individual wards. No alterations were made in the numbers of doctors, their hours, out-of-hours cover, or any other aspect of standard patient care. Outcome measures comprised 30-day mortality and cause, complications and length of stay. Mortality was reduced from 11.7% to 7.6% (p = 0.007, Cox’s regression analysis); adjusted odds ratio was 1.559 (95% confidence interval 1.128 to 2.156). Reductions were seen in Clostridium difficile colitis (p = 0.017), deep wound infection (p = 0.043) and gastrointestinal haemorrhage (p = 0.033). There were no differences in any patient risk factors (except the prevalence of chronic obstructive pulmonary disease), cause of death and length of stay before and after intervention. The underlying mechanisms are unclear, but may include improved efficiency and medical contact time.

These findings may have implications for all specialties caring for patients on several wards, and we believe they justify a prospective trial to further assess this effect.

Our aim was to determine the total blood loss associated with surgery for fracture of the hip and to identify risk factors for increased blood loss. We prospectively studied 546 patients with hip fracture. The total blood loss was calculated on the basis of the haemoglobin difference, the number of transfusions and the estimated blood volume. The hidden blood loss, in excess of that observed during surgery, varied from 547 ml (screws/ pins) to 1473 ml (intramedullary hip nail and screw) and was significantly associated with medical complications and increased hospital stay. The type of surgery, treatment with aspirin, intra-operative hypotension and gastro-intestinal bleeding or ulceration were all independent predictors of blood loss.

We conclude that total blood loss after surgery for hip fracture is much greater than that observed intra-operatively. Frequent post-operative measurements of haemoglobin are necessary to avoid anaemia.
