title: An abdominal aortic aneurysm screening programme for all males over the age of 50 years.
abstract: Previously published ultrasound screening programmes for abdominal aortic aneurysm (AAA) have concentrated on males in the 65 to 75 year age range, suggesting this as the most cost-effective cohort to target. In this unique study we have broadened the criteria for screening. General practitioners in one health district were approached to supply details of all males aged 50 years and over to be offered aortic ultrasound scanning. Over a period of 18 months, 4145 individuals were asked to attend and 3030 (73%) have attended. Attendance rates were: between 50 and 64 years, 73%; between 65 and 79 years, 75%; for 80 years and over, 64%--significantly less (p = 0.01-0.001) than the other two age bands. Aortic dilatation (diameter > or = 2.5 cm) was found in 6.3% of the 50 to 64 year age group, 16.8% of the 65 to 79 year age group, and 23.3% of the 80 years and over age group. An established aneurysm (> or = 4.6 cm) was found in 0.3%--6 individuals (50-64 years), 2.5% (65-79 years) and 4.1% (> or = 80 years). The results suggest that aortic screening may be worthwhile extending to a wider age band. By focusing follow-up, this should give greater value for younger men in terms of community productivity and allows for selective intervention in the elderly.
