Three-Year Audit and Cost Assessment of Open Abdominal Aortic Aneurysm Repair in a District General Hospital

INTRODUCTION: The aims of this study were to audit the outcome of elective open abdominal aortic aneurysm (AAA) repair in a district general hospital, as well as investigate the true costs for this procedure in relation to the national tariff. PATIENTS AND METHODS: A database is maintained on AAA surgery in the trust. Data were supplemented by drawing information from blood bank and clinical notes. Patients with symptomatic or emergency aneurysms were excluded. Data from January 2005 to December 2007 were obtained on demographics, morbidity, 30-day mortality and blood usage. Costs were obtained from the trust finance department. RESULTS: Between January 2005 and December 2007, 79 elective AAA procedures were undertaken. Median age was 75 years (range, 52-85 years), median aneurysm size was 63 mm (range, 42-105 mm) and median ITU stay was 3 days (range, 1-41 days). Major morbidity rate was 20.3% (16 of 79 patients) and 30-day mortality overall was 5.1% (4 of 79 patients). Average cost per case was pound15,012.91 (range, pound4,040.03- pound82,158.00), when National Tariff is pound6,722.00 ( pound5,649.00 x local Market Forces Factor of 1.19). Loss per case for our trust was pound8,290.91 with a total annual loss of pound218,299.56. CONCLUSIONS: Morbidity and mortality in this district general hospital compare well with national studies; however, the total cost is far in excess of the national tariff.
