Guidance

Abdominal aortic aneurysm screening programme supporting information

Updated 7 October 2024

Applies to England

These revised screening standards for the NHS abdominal aortic aneurysm (AAA) screening programme replace previous versions. They apply for data collected from 1 April 2020 unless stated otherwise in the document.

The UK National Screening Committee (UK NSC) recommends men registered with a GP in England are invited for ultrasound screening during the year they turn 65 while men over 65 who have not previously been screened can self-refer. Men who have had previous AAA surgery are not eligible for screening.

NHS AAA screening programme has responsibility for implementing this policy. The programme service specification for NHS providers is available as part of the public health functions exercised by NHS England.

Screening guidance documents on GOV.UK (including this one) may link to a glossary of screening terms, ‘NHS population screening explained’ and NHS UK for definitions of terms. To see the meaning of an acronym, hover over it with your cursor to see the full definition.

1. Summary of changes from previous version of standards

1.1 AAA-S14 diagnosis / intervention: time to first vascular surgeon assessment

Amended to include men with an aorta greater than or equal to 4.0cm that has grown 1cm or more in 1 year referred to a vascular service.

1.2 AAA-S15 diagnosis / intervention: time to vascular surgery

Amended to include men with an aorta greater than or equal to 4.0cm that has grown 1cm or more in 1 year referred to a vascular service.

2. Pathway themes

NHS AAA screening standards look at 4 themes to assess the pathway and 3 key performance indicators (KPIs) are derived from AAA-S04, AAA-S05 and AAA-S06.

2.1 Theme: uptake

Related standards are:

AAA-S01: uptake: completeness of the initial screen offer

AAA-S02: uptake: completeness of the annual surveillance offer

AAA-S03: uptake: completeness of the quarterly surveillance offer

AAA-S08: uptake: initial screen

AAA-S09: uptake: annual surveillance scan

AAA-S10: uptake: quarterly surveillance scan

2.2 Theme: coverage

Related standards are:

AAA-S04: coverage: initial screen

AAA-S05: coverage: annual surveillance scan

AAA-S06: coverage: quarterly surveillance scan

AAA-S07: coverage: initial screen in the most deprived 30% of local areas

2.3 Theme: test

Related standards are:

AAA-S11: test: non-visualised initial screens

AAA-S12: test: time to internal quality assurance

2.4 Theme: diagnosis/intervention

Related standards are:

AAA-S13: diagnosis/intervention: time to nurse assessment

AAA-S14: diagnosis/intervention: time to first vascular surgeon assessment

AAA-S15: diagnosis/intervention: time to vascular surgery

3. Resources to support providers and commissioners

Additional AAA operational guidance is included in the:

4. Reporting and publishing standards

We publish annual standards reports (see the ‘data and standards section’), and quarterly KPI data. We share the data with NHS England before publication.

The data to support the AAA screening standards is collected through the national Screening Management and Referral Tracking (SMaRT) database and IT system. Local providers enter operational data daily and this information is used to calculate the standards. Providers receive quarterly updates on their progress against the standards, which they can validate and sign off. Information relating to surgery is obtained from data entered by the programme and a direct data feed from the national vascular registry into SMaRT.
