Temporal Trend of Transient Ischemic Attack Management over a 10-Year Period: Data from the Rhône County, France
Archive ouverte
International audience. BACKGROUND: Timely recognition and management of transient ischemic attack (TIA) offer the greatest opportunity to prevent subsequent stroke. But variability of TIA management quality exists across hospitals. Under the impetus of national plans, measures were adopted to improve TIA management, including a structured local pathway. Our objective was to compare TIA management between two periods over 10 years, before and after the implementation of these measures. METHODS: A before-and-after study was conducted with two identical population-based cohort studies in 2006-2007 (AVC69) and 2015-2016 (STROKE69) including all patients with TIA diagnosis over a 7-month period in six public and private hospitals in the Rhône county in France. The primary outcome was the adequate TIA management defined as brain and vessel imaging within 24 h of admission and the prescription of antithrombotic treatment at discharge. RESULTS: We identified 109 patients TIA patients in 2006-2007, and 458 over the same period in 2015-2016. A higher proportion of patients were adequately managed in 2015-2016 compared to 2006-2007 (14/96 [15%] in 2006-2007 vs. 306/452 [68%] in 2015-2016, p \textless 0.001). This difference was mainly driven by a marked increase of vessel imaging performed within 24 h of admission, most often by computed tomography angiography. Furthermore, patients called more often emergency medical dispatch before admission, were admitted with a shorter delay after symptom onset, and were more likely discharged to home in 2015-2016 compared to 2006-2007. CONCLUSION: Our study demonstrated an increasing rate of adequate TIA management, mainly driven by a marked increase of vessel imaging within 24 h of admission, over a 10-year period in the Rhône county in France.
