Validation Of ROSIER And FAST Stroke Screen Scales In An Emergency Setting

Objective To explore the value of using two different stroke screen scales(ROSIER, FAST) in a Chinese emergency department, and to detect the influence factors of stroke diagnosis.Methods A total of 237 suspected stroke patients presented to Emergency department in the Second People’s Hospital were prospectively enrolled. Through a detailed patient history taking, patient history, including a series of related general health, medical history, personal history, obstetrical history, etc., patients and their families deny the brain and body trauma suspected new-onset stroke patients(admitted to hospital). After admission to actively improve the relevant tests such as ECG, head CT, head MRI + DWI, chest CT, blood count, electrolytes, glucose, liver and kidney function and other tests. Emergency stroke patient identification Rating Scale score(ROSIER) and face, arms, speech, time scale score(FAST) when patients were admitted to hospital admission, and according to the patient CT or MRI and other auxiliary test results, combined with neurological specialist clinical findings and final diagnosis. Based on this recognition score for Emergency Stroke Scale and face, arms, speech, time rating scale for statistical analysis. Significance analysis of two scales in the emergency diagnosis of suspected stroke patients.Results Among total 237 cases, 177 cases were stroke and 60 cases were stroke mimic. Age, hypertension, smoking history, drinking history, the ROSIER scale and FAST scale were associated with stroke patients. Multivariate regression analysis showed that age(OR=1.051, 95%CI: 1.020-1.084, P=0.001), hypertension(OR=2.721, 95%CI: 1.190-6.224, P=0.018) and ROSIER scale(OR=92.96, 95%CI: 8.098-167.064, P=0.001) were independent risk factors for stroke patients. The ROSIER scale showed a diagnostic Se 79.66℅, Sp 86.66℅, PPV 94.63℅, NPV59.09℅. The FAST scale showed a diagnostic Se76.27℅, Sp81.66℅, PPV92.46℅, NPV53.85℅.Conclusion For emergency suspected stroke patients, FAST and ROSIER rating scale for the early diagnosis of stroke in the emergency has important clinical value; Evaluation ROSIER rating scale score was significantly better than the FAST scale.
