Small trials have suggested that an ultrasound screening programme to detect abdominal aortic aneurysms in older men may be effective
There is uncertainty about the cost effectiveness of routine screening, with widely varying estimates
What this study adds
A cost effectiveness analysis of data from a large randomised trial with follow up over four years showed 47 fewer deaths and additional costs of £2.2m in the group invited to screening
The adjusted net cost per patient was £63.39 and per life year gained was £28 400
The projected cost per life year gained after 10 years was £8000, which is substantially lower than the perceived NHS threshold value
We may want to start screening for AAA. My grandfather died of a ruptured AA. It's still a very common cause of death in the US. And AAA can be treated.
