291 Pre-Operative Venepuncture: An Audit of The Trauma and Orthopaedic Department at The Royal Sussex County Hospital, Brighton

Abstract

Background NICE recommends that patients undergoing intermediate or minor elective surgery do not need routine coagulation or transfusion blood testing unless they are ASA 3+ or taking anticoagulation mediation, where testing may be considered. Currently there is no guidance for trauma patients. Method We identified all patients that underwent intermediate or minor trauma and orthopaedic surgery within a three-month period from December 2019- February 2020 at the RSCH. We excluded major trauma patients, patients taking anticoagulants and patients with complex admission or past medical history. Computer records were used to identify pre-operative investigations and admission history. Results 843 patients met our inclusion criteria. In total, 92 clotting studies and 200 transfusion samples were taken preoperatively. The majority of tests were for patients undergoing ankle 130/292 (45%) or Tibia/Fibula 54/292 (18%) procedures. This equates to approximately 1168 blood tests per year. Based on the lab cost of £15.97 for a transfusion sample and £18 for a coagulation sample, this is a cost of approximately £19,616 each year on blood testing that is not indicated. Discussion We hope that by presenting these results we will help reduce the unnecessary time and financial burden of routine venipuncture in departments undertaking intermediate and minor surgery.
