Reliability of Siriraj stroke score to distinguish between hemorrhagic and ischemic stroke

Abstract

Objective

The aim of study was to establish a quick way to differentiate between hemorrhagic and ischemic stroke by using siriraj stroke score and find its specificity and sensitivity by comparing it with CT scan findings.

Study design

Cross-sectional study.

Place and duration of study

Department of Neurology Pakistan Institute of Medical Sciences Islamabad from Jan 2021 to June 2021.

Methodology

Total 110 patients of acute stroke were included. Any patient of > 20 years old, non-traumatic, focal neurological deficit < 14 days with no obvious reason other than vascular were included. Siriraj stroke score was calculated its findings were compared with a CT scan findings. Data was analyzed by SPSS ver.23.0.

Results

The mean age of patients was 66.10 ± 14.58 years. There were 54 (49.10 %) males and 56 (50.90 %) females. Hypertension was the most common disease found in 79 (71.8 %). The sensitivity, specificity, PPV and NPV of Siriraj stroke score was 83.87 %, 66.6 %, 74.2 % and 71.42 % respectively for hemorrhagic stroke and 93.4 %, 80.95 %, 93.4 % and 37.03 % respectively for non-hemorrhagic stroke.

Conclusion

It is an easy, cost effective and bed side scoring system which can accurately identify the stroke type without any other radiological investigation. It can be employed in areas where CT scan facility is not available and treatment can be started early which will definitely lower mortality and morbidity of stroke patients.
