Answer 1

The risk of short-term mortality following elective AAA repair is dependent on both patient and operative characteristics. The risk of in-hospital mortality following a surgical procedure is commonly estimated using a risk prediction model. A risk prediction model is a mathematical formula that utilises risk factor information to estimate the probability of a patient developing an outcome. Several risk prediction models have been developed and validated for predicting outcomes following AAA repair. A systematic review published in 2008 found that, out of the available risk predication models, the Glasgow Aneurysm Score (GAS) was the most useful model but none was entirely satisfactory.52,53
