Read the latest NHS AAA Screening Programme data report

We have published the NHS Abdominal Aortic Aneurysm (AAA) Screening Programme data for 1 April 2019 to 31 March 2020. This is the first time we’ve published the report in accessible HTML format. This means it can be read and used by as many people as possible.

Please note, you can now switch between chart and table format for some figures by clicking on the ‘change to table and accessible view’ button directly below the figure title.

About the report

This is our sixth year of publishing annual data. This report covers the 12 screening standards for men turning 65 between 1 April 2019 and 31 March 2020, along with outcomes such as the number of aneurysms detected from screening. The impact of the COVID-19 pandemic on invitations, screens and surgery is discussed within the report.


There were 291,904 men eligible for their initial AAA screen between 1 April 2019 and 31 March 2020. Of these men, 76.1% were screened by 31 March 2020 and 0.92% had an aneurysm. There were 8,340 men aged over 65 who self-referred into the programme and 88.9% were screened by 31 March 2020. The aneurysm detection rate in self-referred men was higher than cohort men, at 3.8%.

Thank you

The report is a testament to the hard work of everyone involved in the screening programme at both local and regional levels. We would like to thank all those involved in collecting and collating the data, producing the report, and most of all those from the NHS who deliver the screening services.
