Key result
National screening detects a 1.7% AAA incidence among 65-year-old men.
Why the study?
A nationally funded aortic aneurysm screening programme for 65 year old men was implemented in England to achieve national coverage and standardization, but challenges remain regarding incidence rates, measurement methods, and quality assurance.
Observational (n=100,000)
Yes
The rollout of a national AAA screening program in England for 65-year-old men demonstrated a 1.7% incidence rate, which is lower than expected but remains cost-effective.

May reduce cost-effectiveness of national AAA screening; leaves open whether updated models are needed before full rollout.
A nationally funded aortic aneurysm screening programme for 65 year old men commenced in 2009 in England. The aim is to implement screening by commissioning local programmes covering populations of over 800,000 to a national standard. By April 2012 approximately 80 per cent of England will be covered, with the aim to complete roll out by 2013. So far, almost 100,000 65 year old men have been screened, and over 1000 abdominal aortic aneurysms detected. The incidence rate of 1.7 per cent is lower than expected, but updated calculations suggest that the programme remains cost effective. Other issues under discussion are the method of measurement of aortic diameter, and a quality assurance programme to guarantee the national standard. The key to a successful long-term programme will be its ability to remain flexible and responsive to emerging data.

J.J. Earnsh (2012) conducted an observational in Abdominal Aortic Aneurysm (n=100,000). National aortic aneurysm screening programme was evaluated on Abdominal aortic aneurysm incidence. A national screening programme in England detected over 1,000 abdominal aortic aneurysms among almost 100,000 65-year-old men, yielding an incidence rate of 1.7%.
