Adherence to practice guidelines for transient ischemic attacks in an emergency department

Area of Science:

• Neurology
• Emergency Medicine
• Clinical Research

Background:

• Transient ischemic attacks (TIAs) are critical indicators of future stroke risk.
• Effective emergency department (ED) management of TIAs is crucial for timely intervention.
• Tertiary care teaching hospitals play a key role in stroke prevention strategies.

Purpose of the Study:

• To evaluate the current diagnostic and therapeutic practices for patients presenting with TIA in an ED setting.
• To identify variations in the investigation and treatment protocols for TIA patients.
• To assess the adherence to best practices in TIA management within a neuroscience referral center.

Main Methods:

• Retrospective chart review of consecutive ED patients diagnosed with TIA.
• Standardized data collection by independent coders.
• Analysis of demographic data, diagnostic workup, and treatment interventions.

Main Results:

• 293 TIA charts were reviewed (mean age 66 years, 1:1 gender ratio).
• Most patients (75%) were evaluated by ED physicians; median time from symptom onset to ED arrival was 29 hours.
• Diagnostic workup included CT scans (81%), CBC (74%), and ECG (75%). Carotid doppler was underutilized (16% in ED, 26% outpatient booking). Antithrombotic medications were not prescribed to 28% of discharged patients.

Conclusions:

• Significant practice variations exist in TIA investigation and treatment at this tertiary care hospital.
• Carotid doppler utilization and prescription of anti-platelet therapy for TIA patients are suboptimal.
• Implementation of clinical practice guidelines and rapid assessment TIA clinics may improve patient outcomes.
