ABSTRACT

Background: Stroke is a leading cause of death, this disease is diagnosed by tomography (CT), however, not all hospitals have this resource, this study aims to establish the sensitivity and specificity for the Siriraj score and compare with the modified score.
Material and methods: We included patients with stroke admitted to hospitals of the Health Department, in the first 24 hours of admission was measured the Siriraj score and modified score and determined the sensitivity and specificity for both tests. We measured the area under the ROC curve.
Results: A total of 82 patients, 57 with ischemic stroke and 25 with hemorrhagic stroke, in patients with hemorrhagic stroke the presentation was more frequent in men (p = 0.04). The mean diastolic blood pressure (DBP) in patients with ischemic stroke was 86 mmHg, while mean DBP in hemorrhagic stroke was 99 mmHg, a difference of 13 mmHg (p = 0.0011). For ischemic stroke the Siriraj score had a sensitivity of 54% and specificity 80%, the modified score had a sensitivity of 63% and specificity of 80%, for hemorrhagic stroke the Siriraj score had a sensitivity of 60% and specificity 84%, the modified scale had a Sensitivity of 52% and specificity 84%.
Conclusion: We evaluated the Siriraj score and the modified score, this modification not increases the sensitivity and specificity for the test, these scores are not enough precise to establish the diagnosis in stroke.
