Key result
An extensive scoring system incorporating additional risk factors may identify almost 90% of abdominal aortic aneurysms, compared to less than 30% captured by standard screening criteria.
Why the study?
Does an extensive scoring system improve AAA detection rates compared to USPSTF screening criteria in at-risk populations?
Does an extensive scoring system improve AAA detection rates compared to USPSTF screening criteria in at-risk populations?
Expanding AAA screening criteria beyond age and smoking history to include other cardiovascular risk factors could substantially increase detection rates.
May support expanded AAA screening criteria; leaves open whether scoring systems improve outcomes before changing USPSTF practice.
The prevalence of abdominal aortic aneurysms (AAAs) and AAA-related deaths are steadily declining in some countries as a result of the reduction in smoking rates. It was thus suggested that screening programs that do not target high-risk populations are likely to have very low AAA detection rates. However, this may not apply to other countries that do not exhibit similar reductions in smoking rates. It was assumed that by using the U.S. Preventive Services Task Force screening criteria (men 65-75 years with smoking history) less than 30% of AAAs would be captured. A more extensive scoring system that includes additional risk factors such as the presence of carotid artery or peripheral arterial disease, obesity, hypertension, and so on, may identify almost 90% of AAAs. This article discusses this and other issues on screening, prevention, and treatment of AAAs.

Paraskevas et al. (2013) conducted a review in Abdominal aortic aneurysms. Extensive scoring system for screening vs. U.S. Preventive Services Task Force screening criteria was evaluated. An extensive scoring system incorporating additional risk factors may identify almost 90% of abdominal aortic aneurysms, compared to less than 30% captured by standard screening criteria.
