In Hospital Episode Statistics (HES, hospital admission data) we used ICD-10 terms (see below) for
AAA diagnosis when marked as the primary diagnosis i.e. the main condition treated or
investigated during the relevant episode of healthcare. We used the date of admission to
hospital as the date of the event. We additionally searched for OPCS-4 terms indicating the emergency repair of an aneurysmal segment of the aorta.
