It is estimated 5% of patients over 65 years receive warfarin therapy. This paper aims to analyse whether a time delay to hip fracture fixation while waiting for the patients International Normalised Ratio (INR) to return to normal increases the mortality risk. A prospective database of 937 hip fractures was analysed. Patient demographics and time from admission to operation were recorded. The patients' INR on admission and during the preoperative period, the need for vitamin K reversal, and any postoperative thromboembolic compilations were recorded. Thirty-day mortality was obtained from the General Register Office for Scotland. Patients with a therapeutic INR were categorised into two groups: those who received vitamin K within 24 hours of admission and those who did not.Introduction
