Implementation

Use MODIFIED CALIBER 'Abdominal aortic aneurysm' phenotyping algorithm:

At the specified date, a patient is considered to have an 'Abdominal aortic aneurysm' IF they meet any of the criteria below on or before the specified date. 

The earliest date on which the individual meets any of the following criteria on or before the specified date is defined as the first event date:
1.	Primary care 
    1.	Diagnosis of AAA during a consultation: arterial_gprd: category 4
    2.	Performance of emergency AAA repair procedure recording during a consultation: aaa_ops_gprd: category 3
    3.	History of AAA during a consultation. The following Read code from CPRD:
    1.	Read:14AE.00	Medcode:16993	Descr:H/O: aortic aneurysm
2.	Secondary care 
    1.	Diagnosis of AAA as the primary or secondary diagnosis of any hospitalization: arterial_hes: category 4
    2.	Performance of emergency AAA repair procedure recorded: aaa_ops_opcs: category 3
