Clinical Report: Assessing the Effectiveness of the RACE Score in Stroke Evaluation
Overview
This study evaluates the RACE score's effectiveness in distinguishing true strokes from mimics in emergency settings. The findings indicate that higher RACE scores correlate with confirmed strokes and large vessel occlusion (LVO), suggesting its utility in acute stroke workflows.
Background
Rapid and accurate differentiation between true strokes and stroke mimics is crucial in emergency departments, as misclassification can lead to inappropriate treatment decisions. Stroke remains a leading cause of morbidity and mortality globally, necessitating effective diagnostic tools. The RACE score has emerged as a potential adjunct to clinical assessment in identifying LVO, which significantly impacts treatment outcomes.

Key Findings
The mean RACE score was significantly higher in stroke patients compared to stroke mimics (3.15 vs. 1.64, p < 0.001).
Patients with RACE scores ≥5 were more frequently diagnosed with stroke (30.8% vs. 8.8%, p < 0.001).
LVO was identified in 15.4% of patients, with higher RACE scores in these cases (4.59 vs. 1.85, p < 0.001).
Logistic regression indicated a significant association between higher RACE scores and the presence of LVO (OR 1.59, 95% CI 1.38–1.83, p < 0.001).
Older patients were more likely to be diagnosed with stroke compared to those with mimics (69.13 vs. 61.67 years, p = 0.001).
Clinical Implications
The RACE score can enhance the accuracy of stroke evaluations in emergency departments, aiding in the rapid identification of true strokes and LVO. Incorporating the RACE score into clinical workflows may improve patient outcomes by facilitating timely and appropriate interventions.
Conclusion
The RACE score serves as a valuable tool in differentiating strokes from mimics in emergency settings, with higher scores indicating a greater likelihood of LVO. Its integration into acute stroke protocols may optimize diagnostic accuracy and treatment efficacy.
