Objective: The aim of the study is to validate whether the Recognition Of Stroke In the Emergency
Room (ROSIER) scale can be used by general practitioners (GPs) in an emergency medical service
(EMS) protocol to transfer stroke patients from primary care center to advanced hospital with acute
stroke center. Methods: GPs prospectively performed the ROSIER scale and the Cincinnati Prehospital
Stroke Scale (CPSS) on suspected stroke patients as a transfer protocol. All patients were immediately
transferred to the Level-II hospital for further treatment. Results: 468 of the 512 suspected stroke
patients met the inclusion criteria in this study. The ROSIER scale showed a diagnostic sensitivity
of 83.13% (95% confidence intervals [CI] 79.74-86.52%) and specificity of 80.88% (95% CI 77.32-
84.44%). The CPSS showed a diagnostic sensitivity of 78.01% (95% CI 74.26-81.76%) and specificity
of 70.59% (95% CI 66.46-74.72%). The Kappa statistic value of the ROSIER scale and the CPSS
were 0.601 and 0.454, respectively. The area under the curve (AUC) of ROSIER scale was large than
the CPSS (AUC 0.855 vs. 0.791). However, the difference was not significantly different.
Conclusions: This study suggest that ROSIER and CPSS could be used in an EMS protocol to transfer
stroke patients from a primary care center to an advanced hospital offering thrombolysis service
