This study states that International guidelines recommend carotid revascularization within 14 days for patients with a symptomatic transient ischemic attack (TIA) or stroke event. However, significant delays in care persist, with only 9% of outpatients and 36% of inpatients in Ontario meeting this target. The study objective was to explore the influence of health system factors on carotid revascularization timelines. We conducted a retrospective chart review of all symptomatic TIA/stroke patients undergoing carotid endarterectomy or stenting at The Ottawa Hospital (2015-2016). The primary outcome was time from TIA/stroke to carotid revascularization. Health system variables of interest included location and timing of patient presentation, timelines to vascular imaging, and same-day collaboration between key services such as emergency, neurology, and surgery. Descriptive statistics and univariate analysis were used to determine statistically significant differences between groups. A total of 228 records met the inclusion criteria. The median time from TIA/stroke to carotid revascularization was 10 days, with 58% of patients meeting the 14-day guideline.
