Commentary on 'Comparison of three contemporary risk scores for mortality following elective abdominal aortic aneurysm (AAA) repair'

摘要

In the study by Grant et al., three contemporary risk scores are externally validated using a cohort of aneurysm repairs from a database held in the North West of England. The authors state that all three demonstrate good calibration and discrimination for predicting in-hospital mortality following elective abdominal aortic aneurysm (AAA) repair, although in a cohort with only 32 deaths.As the authors say in their opening statement, there are no widely used scoring systems in clinical practice to guide whether a patient should, or should not, undergo intervention for an AAA. There are a number of reasons for this and all should continue to be used with caution.
