APACHE II scores  and Glasgow Aneurysm Scores (GAS)  are commonly used in ICUs to predict mortality. These scoring systems (scores α mortality), when applied to postoperative emergency open abdominal aortic aneurysm (AAA) repair patients, yield varying results. We applied these scoring systems to our patients to establish their predictive value in our clinical setting.
This retrospective audit included patients who underwent emergency open AAA repair and were admitted to our ICU, over a period of 1 year (November 2008 to November 2009). These patients were identified from our local ICU database (Metavision®) and scores (APACHE II and GAS) were calculated for each of these patients. The mortality rates were compared with the national average .
APACHE II scores seem to be more predictive of our unit AAA mortality rates than GAS scores. We aim to apply these scores to a larger dataset and also determine possible reasons for improved survival.
