Key result
High-risk ABCD2 scores after TIA linked to ~18% greater 1-year mortality versus low-risk scores.
Why the study?
Long-term outcomes for Medicare beneficiaries hospitalised with transient ischaemic attack and the role of ABCD2 score in identifying high-risk individuals were not studied.
Does a high ABCD2 score (≥4) predict higher 1-year mortality and rehospitalization compared to a low score (0-3) in Medicare beneficiaries hospitalized for TIA?
Population
40,825 Medicare beneficiaries hospitalised for TIA from 2011 to 2014
Comparison
High risk ABCD2 score (≥4) vs low risk ABCD2 score (0–3)
Design
Cohort study using Get With The Guidelines-Stroke hospitals data
Follow-up
1 year

ABCD2 may identify higher 1-year mortality and ischaemic stroke risk after TIA in Medicare patients; leaves open whether it should guide targeted long-term interventions.
Cohort (n=40,825)
Yes
Does a high ABCD2 score (≥4) predict higher 1-year mortality and rehospitalization compared to a low score (0-3) in Medicare beneficiaries hospitalized for TIA?
Hazard Ratio: 1.18 (95% CI 1.07–1.3)
The ABCD2 score effectively stratifies long-term risk of mortality and ischemic stroke readmission in older adults hospitalized for TIA.
Shah et al. (2020) conducted a cohort in Transient ischaemic attack (TIA) (n=40,825). High-risk ABCD2 score (≥4) vs. Low-risk ABCD2 score (0-3) was evaluated on Mortality at 1 year (HR 1.18, 95% CI 1.07 to 1.30). Medicare beneficiaries with TIA and a high-risk ABCD2 score (≥4) had a significantly higher risk of 1-year mortality compared to those with a low-risk score (adjusted HR 1.18; 95% CI 1.07-1.30).
