Logic Description : Cohort entry indexed on procedure occurrence of ‘Carotid Endarterectomy’ (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: Carotid endarterectomy is a surgical procedure that involves the removal of atherosclerotic plaque and stenotic lesions from the carotid artery, typically the internal or common carotid artery. It is primarily performed to reduce the risk of cerebrovascular events, especially strokes. The choice between carotid endarterectomy (CEA) and carotid artery stenting (CAS) depends on various factors, including the patient’s medical comorbidities and the anatomic characteristics of the symptomatic carotid artery. Patients who are candidates for CEA usually have moderate or severe symptomatic carotid stenosis. CEA is recommended over CAS when specific conditions are met, including having experienced an ipsilateral transient ischemic attack (TIA) or nondisabling ischemic stroke as the symptomatic event, having a surgically accessible carotid artery lesion, no prior ipsilateral endarterectomy, and no contraindications to revascularization. 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.
