Stroke TIA Public Triage Tool (ABCD2 community adaptation)

Stroke TIA Public Triage Tool (ABCD2 community adaptation): Explanation and Clinical Context The ABCD2 score estimates early stroke risk after a transient ischemic attack (TIA) based on five clinical variables: age ≥ 60 years (1), blood pressure ≥ 140/90 mmHg (1), clinical features (unilateral weakness 2; speech disturbance without weakness 1), symptom duration (≥ 60 minutes 2; 10–59 minutes 1), and diabetes (1). Total 0–7. Risk stratification: Low (0–3), Moderate (4–5), High (6–7).

Approximate risks: 2-day 1.0–8.1%; 7-day 1.2–11.7%; 90-day 3.1–17.8%. Community adaptation: This version adds triage guidance. Ongoing symptoms or onset ≤ 24h → emergency.

High score → urgent evaluation; low score → early clinic follow-up.
