Comparison of Siriraj and Guy's Hospital score to differentiate supratentorial ischaemic and haemorrhagic strokes in the Indian population.

In India, 70% of the population does not have access to computerised brain scanning. Siriraj score is a safe and reliable clinical method to asses acute stroke syndrome. 160 patients with acute stroke were analysed by Siriraj and Guy's hospital stroke score simultaneously. CT Scan was performed in all and subarachnoid haemorrhage was excluded. Ninety two patients (57.5%) had infarction and 68 (42.5%) had haemorrhage. Siriraj score formula revealed haemorrhage in 53 (80%) and infarction in 78 (83%), while in the rest the results were equivocal or incorrect. Guy's hospital score revealed haemorrhage in 45 (66%) and infarction in 59 (69%). Clinical features are also helpful in differentiating infarction from haemorrhage, but the accuracy is not as high as with Siriraj score and secondly Siriraj score is a very simple formula in comparison to Guy's score.
