Implication

ABCD2 score may have limited value for early stroke prediction after TIA; challenges guideline recommendations and leaves open need for prospective validation.

Does a moderate-high ABCD2 score accurately predict early stroke risk in patients with emergency department-diagnosed TIA?

Population

827 patients with emergency department-diagnosed transient ischaemic attack (TIA) at two hospitals over 3 years (2004-2006) in South Western Sydney.

Intervention

Moderate-high ABCD2 score

Comparator

Low ABCD2 score

Outcome

Stroke occurrence at 30 dayshard clinical

The ABCD2 score demonstrated poor predictive value for early stroke risk in a modern emergency department TIA cohort, suggesting a need to reevaluate its role in national guidelines.
