This data report presents data against each of the 15 screening standards for screening activity related to abdominal aortic aneurysm (AAA) screening.
The data source used for this report is AAA SMaRT (screening management and referral tracking).
The NHS AAA screening programme aims to reduce aneurysm-related mortality through early detection, appropriate monitoring and treatment. The NHS AAA screening programme invites men for ultrasound screening during the year (1 April to 31 March) in which they turn 65. Men over 65, who have not previously been screened can self-refer. The programme offers annual or quarterly surveillance for all men who on initial scan are found to have a small or medium aneurysm respectively. Men found to have a large aneurysm are referred into the care of specialised vascular services for potential intervention.
National AAA standards provide a defined set of measures that providers must meet to make sure services are safe and effective. The NHS AAA screening programme published a set of revised standards in April 2020.
This report is an official statistic. Official statistics are an essential public asset. They provide a window on society, the economy, and on the work and performance of government. They are fundamental to the judgements and decisions made by the public, by government, and by a large range of other organisations.
AAA Standards
There are 15 national AAA standards included in this report, which are:
* AAA-S01: completeness of offer (initial screen)
* AAA-S02: completeness of offer (annual surveillance scan)
* AAA-S03: completeness of offer (quarterly surveillance scan)
* AAA-S04: coverage (initial screen)
* AAA-S05: coverage (annual surveillance scan)
* AAA-S06: coverage (quarterly surveillance scan)
* AAA-S07: coverage of the initial screen in men living in deciles 1 to 3
* AAA-S08: uptake (initial screen)
* AAA-S09: uptake (annual surveillance scan)
* AAA-S10: uptake (quarterly surveillance scan)
* AAA-S11: non-visualised screens
* AAA-S12: internal quality assurance
* AAA-S13: nurse assessments
* AAA-S14: men seen at specialist assessments within 2 weeks
* AAA-S15: men operated on within 8 weeks
Standards data are published annually. Standard AAA-S04, AAA-S05 and AAA-S06 are also key performance indicators (KPIs), which are published quarterly.
Two thresholds, the acceptable threshold and achievable threshold are specified for each standard.

2. AAA-S01: completeness of offer (initial screen)
There were 337,752 men aged 65 eligible for AAA screening between 1 April 2024 and 31 March 2025; 99.8% of those eligible men were offered an initial screen within the screening year plus 2 months. The reasons for not being invited include:
* offered after 31 May 2025
* incorrect contact details
* deferring screening
* opting out of the screening programme
* not offered

Figure 2: percentage of eligible cohort men offered screening according to the standard definition, by region, England, 1 April 2017 to 31 March 2025
The offer of the initial screen to men in each cohort year was stable between 2013/14 and 2019/20 (see previous years’ reports for data prior to 2017/18). Following the sharp drop in 2020/21 performance due to the impact of the COVID-19 pandemic, performance increased year on year until 2023/24 (99.8%) maintaining this level in 2024/25 (99.8%). The AAA screening programme is meeting the acceptable threshold and just below the achievable threshold, returning to pre-pandemic levels.

The data for the report showed the following provider level information:
* 21 out of 38 screening providers met the acceptable threshold of ≥ 75.0%
* 2 out of 38 screening providers also reached the achievable threshold of ≥ 85.0%
* South Devon AAA Screening Cohort (85.5%) had the highest performance and Peninsula AAA Screening Cohort (85.3%) also reached the achievable threshold of ≥ 85.0%

Figure 10: coverage - percentage of men in the eligible cohort who were tested and who lived in a lower super output area (LSOA) classed as decile 1 to 3 in the English indices of deprivation (IoD) 2019, England, 1 April 2020 to 31 March 2025
Men living in more deprived areas are less likely to attend for screening but are more likely to have an aneurysm. It is important for providers to engage with men living in more deprived areas to make sure they can make a personal informed choice.
This standard is now in the fifth year of being reported and it should be reviewed alongside standard 4. It was first introduced in April 2020, however performance during 2020/2021 was impacted by the COVID-19 pandemic. Performance has increased year on year and this is the first year that the acceptable threshold has been met.
9. AAA-S08: uptake (initial screen)
There were 337,752 men offered AAA screening between 1 April 2024 and 31 March 2025; 82.3% of those men offered an initial screen were conclusively tested within the screening year plus 2 months.

12. AAA-S11: non-visualised screens

Two providers in the above table reported 1.0% but the actual value was slightly above 1.0%, meeting the acceptable but not the achievable threshold.

16. AAA-S15: men operated on within 8 weeks
Of the 728 men with an aorta of ≥ 5.5cm or men with an aorta ≥ 4.0cm that has grown ≥ 1cm in one year, deemed fit for intervention and not declining 31.7% were operated on by a vascular specialist within 8 weeks.

The data for the report showed the following provider level information:
* 6 out of 38 screening providers met the acceptable threshold of ≥ 60.0%
* 3 out of 38 screening providers also reached the achievable threshold of ≥ 80.0%
* West Yorkshire AAA Screening Cohort (100.0%) had the highest performance, all men operated on within 8 weeks
* Bristol, Bath and Weston AAA Screening Cohort, Five Rivers AAA Screening Cohort and Leicester AAA Screening Cohort (0.0%) had the lowest performance, no men operated on within 8 weeks
Figure 21: referral - percentage of men with aorta ≥ 5.5cm or men with an aorta ≥ 4.0cm that has grown ≥ 1cm in one year, deemed fit for intervention and not declining, operated on by a vascular specialist within 8 weeks, by region, England, 1 April 2017 to 31 March 2025
The percentage of men operated on within 8 weeks fell to 38.5% in 2019/20. It continues to gradually increase nationally from a low of 24.1% in 2020/21 during the COVID-19 pandemic. For 2024/25 (31.7%), performance has improved 0.1 percentage points from 2023/24 (31.6%), but it is still considerably below the acceptable threshold.
17. Outcomes
The number of fatal and non-fatal AAA ruptures presented are only those reported to the screening provider and will only be for those men who have been screened. This number may, therefore, be an underestimate of the true number of AAA ruptures.
There were 32 AAA ruptures during the screening year. 24 of which were fatal. 15 of the 24 deaths were in men on surveillance and 9 had been referred for surgery.
The 15 fatal AAA ruptures in men on surveillance represented 2.8% of the 252 deaths in men on surveillance.
For the men referred to surgery, 3 had been turned down or had declined the operation and 6 died while waiting for surgery. Of the 6 who died while waiting for surgery, 5 died after waiting more than 8 weeks for surgery.
In 2023/24, 9 men died while waiting for surgery, 6 of whom died after waiting more than 8 weeks from their referral.
