Key result
Outpatient care in a rapid-access stroke prevention clinic using the ABCD2 score for triage resulted in a 90-day stroke rate of 3.2%, compared with an ABCD2-predicted risk of 9.2%.
Why the study?
Does an ABCD2-based ED triaging tool with outpatient management reduce 90-day stroke rates in patients with TIA?
Cohort (n=982)
Yes
Does an ABCD2-based ED triaging tool with outpatient management reduce 90-day stroke rates in patients with TIA?
Absolute Event Rate: 3.2% vs 9.2%
Outpatient care in a rapid-access stroke prevention clinic using ABCD2 triage for TIA is associated with a lower 90-day stroke rate than predicted, avoiding hospital admission for most patients.
No takes yet. Share an insight, caveat, or question.
May support ABCD2-guided outpatient TIA care to lower observed stroke rates; leaves open confirmation versus standard management in randomized trials.
Wasserman et al. (2010) conducted a cohort in Transient ischemic attack (TIA) (n=982). ABCD2-based ED triaging tool with outpatient management vs. ABCD2-predicted risk was evaluated on Stroke by 90 days of index TIA. Outpatient care in a rapid-access stroke prevention clinic using the ABCD2 score for triage resulted in a 90-day stroke rate of 3.2%, compared with an ABCD2-predicted risk of 9.2%.
