<p>The ABCD<sup>2</sup> clinical prediction rule is a seven point summation of clinical factors independently predictive of stroke risk. The purpose of this cohort study is to validate the ABCD<sup>2</sup> rule in a Bulgarian hospital up to three years after TIA.</p>
<h4>Methods</h4>
<p>All consecutive admissions to an emergency department with symptoms of a first TIA were included. Baseline data and clinical examinations including the ABCD<sup>2</sup> scores were documented by neurologists. Discrimination and calibration performance was examined using ABCD<sup>2</sup> cut-off scores of ≥3, ≥4 and ≥5 points, consistent with the international guidelines. The Hosmer-Lemeshow test was used to examine calibration between the observed and expected outcomes as predicted by ABCD<sup>2</sup> score within the logistic regression analysis.</p>
<h4>Results</h4>
<p>Eighty-nine patients were enrolled to the study with a mean age of 63 years (+/- 12 years). Fifty-nine percent (n = 53) of the study population was male. Seven strokes (7 · 8%) occurred within the first year and six further strokes within the three-year follow-up period. There was no incident of stroke within the first 90 days after TIA. The rule demonstrated good predictive (OR = 1 · 58, 95% CI 1 · 09-2 · 29) and discriminative performance (AUC<sub>ROC</sub> = 0 · 72, 95% CI 0 · 58-0 · 86), as well as a moderate calibration performance at three years.</p>
<h4>Conclusion</h4>
<p>This validation of the ABCD<sup>2</sup> rule in a Bulgarian hospital demonstrates that the rule has good predictive and discriminative performance at three years. The ABCD<sup>2</sup> is quick to administer and may serve as a useful tool to assist clinicians in the long-term management of individuals with TIA.</p>
