Validation of Siriraj Score among Stroke Patients in a Tertiary Care Hospital in North India

Background Stroke is a leading cause of Cardiovascular mortality in India and the world over. Two types of strokes are more common, Ischemic and Haemorrhagic. The prompt diagnosis and differentiation between the two is of paramount importance for treatment. However CT scan, as conventionally used, is not available in many peripheral parts of India. Siriraj score provide an effective bedside tool for this differentiation. However it has not yet been validated in India. Method 200 patients admitted in the hospital satisfying the WHO definition of stroke were evaluated and Siriraj score evaluated for them. They were subjected to CT scan and the results compared. Results Siriraj score had a sensitivity of approximately 93 % and 65 % for Haaemorhhagic and Ischemic Strokes respectively, while specificities were 91 % and 71 % respectively Conclusion The Siriraj score has a good utility in Indian population in differentiating between Haemorrhagic and Ischemic strokes bed side, without mandating a CT scan in peripheral locations, where CT facilities is not available.
