Logic Description : Cohort entry indexed on procedure occurrence of a ‘Abdominal Aortic Aneurysm Repair’ (earliest event) with the following additional inclusion criteria:

• Age > 18

• Inpatient visit on day of surgery, and day after surgery, and no ED visit on, or in the 48h prior to surgery (i.e. non emergent surgery, requiring overnight stay in hospital).

• Observation period requirement of 365d

• Cohort exit: end of observation.

*Submitted version contains ICD9 Procedure codes, which are non-standard concepts.

Recommended Study Application: Target

Assertion Statement: This cohort definition was executed on at least one real person-level observational health data source and resulted in a cohort with at least 1 person.

Clinical Description: Abdominal aortic aneurysm repair is a surgical procedure involving the correction or reinforcement of a weakened or bulging segment of the abdominal aorta, a major blood vessel. This procedure is performed to prevent the risk of aneurysm rupture, which can be life-threatening, by either surgically excising the aneurysm and replacing it with a graft (open surgery) or by using minimally invasive techniques to insert a stent graft to reinforce the weakened area (endovascular repair). The logic in this definition aims to select for a cohort undergoing non emergent procedures. Further details to aid in the population level evaluation of this cohort will be posted to this thread.

Evaluation Conclusion: Pending
