Efficacy of routine local and national coding (Hospital Episode Statistics data and death certification) in identifying acute abdominal aortic aneurysm events as compared to OXVASC ascertainment. OXVASC ascertainment is taken as the gold standard. ICD10 refers to the International Classification of Diseases, 10th Revision. I713 is the code for acute/ruptured abdominal aortic aneurysm. I711, I713, I715, and I718 codes refer to acute/ruptured aortic aneurysms at other anatomical locations. Only incident events were analyzed. For specificity calculations, the total number of OXVASC incident acute aortic events (179) during the 12-year study period was used. OXVASC indicates the Oxford Vascular Study.
