Introduction: Acute stroke is one of the most common and debilitating diseases. Rapid diagnostic measures after entering the hospital and shortening the duration of treatment will increase the chances of access to treatment. The purpose of this study is to examine the accuracy of Field Assessment Stroke Triage for Emergency Destination (FAST-ED) in terms of stroke diagnosis.
Methods: This prospective diagnostic accuracy study had been conducted between March 2019 to January 2020. All adult patients transferred to the ED and suspected of having an acute ischemic stroke who had undergone brain magnetic resonance imaging (MRI) were eligible. After data collection, receiver operating characteristic curve, sensitivity, specificity, positive predictive value, and negative predictive value of FAST-ED were calculated and compared with the NIHSS scale.
Results
A total of 314 patients who receive MRI in the first 24 hours of symptom onset were included in this study. The mean age was 67.95 ± 13.11 years and 184 patients (58.60%) were males. Of all suspected patients, 274 patients (87.26%) had ischemic stroke based-on gold standard diagnosis.
The best predictor of stroke in FAST-ED with a sensitivity of 0.880 and specificity of 0.575 was a cut-off point of 2 (AUC: 0.836). Distribution of all FAST-ED symptoms was significant in stroke and non-stroke group except " Eye deviation ".
Conclusions
FAST-ED scale is relatively simple and has a comparable ability for recognizing AIS to more complex NIHSS.
