Comparison of Siriraj Stroke Score with Computerized Tomography in Establishing the Type of the Stroke among Pakistani Population

Abstract

Computed Tomography (CT) Scan is an accurate and a routinely done imaging technique to diagnose and differentiate haemorrhagic and ischaemic stroke. Siriraj Stroke Score (SSS) is weighted clinical score and European recognized for clinical and bedside differentiation between ischemic and haemorrhagic stroke. This study aimed to establish the accuracy of SSS in the bedside diagnosis of cerebral haemorrhage in comparison with CT scan to avoid delay in treatment. Total 152 patients were included in the study. Out of which 39.5% were male. Overall, mean age was 59.2811.91, 56.32 12.69 in haemorrhagic group and 62.3210.28 in non-haemorrhagic group. Sensitivity, specificity, PPV, and NPV of SSS for haemorrhagic stroke was 71.4%, 81.3%, 79.7% and 73.5% respectively. Overall accuracy for haemorrhagic stroke was found to be 76.3%. SSS had higher sensitivity for haemorrhagic stroke and is more sensitive in Asian population, but still not accurate enough to replace CT scan as investigation of choice but can plays a role to avoid delay in the management where CT scan is delayed or not available. 2015, TIP ARASTIRMALARI DERNEGI.
