Haemoglobin and transfusions in elderly patients with hip fractures: the effect of a dedicated orthogeriatrician.

Abstract

Hip fractures are common in elderly patients, in whom it is important to monitor blood loss; however, unnecessary transfusions should be avoided. The primary objective of this study was to assess whether the employment of a dedicated orthogeriatrician in an Orthopaedic Department allows to optimise the clinical conditions of patients, influencing blood loss and consequently the number of transfusions. The secondary objective was to determine whether the influence of the orthogeriatrician differs according to the type of surgical treatment. A total of 620 elderly patients treated for hip fracture were included in the study. These patients were divided into two groups according to the presence or not of the orthogeriatrician. For each patient, age, sex, comorbidities, type of fracture, surgical treatment, length of hospital stay, time from hospitalisation and surgery, time from surgery to discharge, haemoglobin (Hb) values (admission, 24h post-surgery, lowest Hb reached, discharge) and the number of transfusions were recorded. Regardless of the surgical procedure performed, in patients managed by the orthogeriatrician, the Hb at discharge was significantly higher (p = 0.003). In addition to the highest Hb at discharge, in patients who underwent hemiarthroplasty, the number of transfusions per patient is significantly reduced (p = 0.03). The introduction of the orthogeriatrician in an orthopaedic ward for the management of elderly patients treated for hip fracture allows to discharge the patients with higher Hb values, reducing the risk of anemisation and the costs related to possible re-admission.
