Clinical Agreement between Nurses in the Ultrasound Measurement of Abdominal Aortic Diameter within a National Screening Programme.

Background: Accurate measurement is central to abdominal aortic aneurysm screening, but information concerning differences between observers using modern ultrasound devices is lacking. Our aim was to assess clinical agreement among nurses within a national screening programme.

Methods: Between-observer repeatability was assessed among 2 pairs of nurses (A & B and C & D) screening a consecutive series of men at a single-community clinic in Grampian, Scotland.
