Abstract

Purpose: A correct diagnosis of stroke is important for immediate treatment. The aim of this study is to determine the accuracy of two clinical stroke scores (Siriraj Stroke Score and Guy’s Hospital Score) in patients with acute stroke.
Method: Fifty two patients with acute stroke confirmed by D-WMRI were analyzed by Siriraj Stroke Score (SSS) and Guy’s hospital score (GHS). We evaluated the sensitivity and specificity between the two clinical stroke scores.
Result: Forty six patients (88%) had infarctions and six patients (6%) had hemorrhages. The sensitivity of SSS was 89% for infarction (equivocal cases were excluded). The GHS had a sensitivity of 88% for infarction. Both SSS and GHS could not detect hemorrhage.
Conclusion: In this study, neither of the two clinical stroke scores is sufficiently accurate for the differentiation of stroke type. We suggest that scoring systems that only require a small number of variables are unlikely to achieve the level of accuracy needed for clinical decision-making.
