Purpose: We wanted to evaluate the utility of the SimplifiedMotor Score (SMS) for prediction of outcome for adult
stroke patients.
Methods: This was a prospective study of adult stroke patients from May to October, 2007. Emergency medicine
residents independently checked the Glasgow Coma Scale (GCS) for each patient at the same time that interns otherwise,
senior medical students (MS) and nurses checked the 3-point SMS within 5 minutes of patients arrival at our
emergency care center. We telephoned the patients or their families to inform them of intubation, or death and to check
the cerebral performance category (CPC) on the first- day and- first month after the patients’ visits.
Results: Fifty-eight patients were enrolled in this study. ach SMS of evaluation by interns, MS and nurses was
correlated with GCS (Correlation Coefficient=0.63, 0.59, 0.61; p<0.01, respectively). In the case of mortality within 24
hours, the AUC (area under the curve) for GCS was 0.46 and the AUCs for SMS of interns, MS and nurses were
0.94, 0.94, and 0.94. In the case of intubation within 24 hours, the AUC for GCS was 0.81 and the AUCs for SMS
of interns, MS and nurses were 0.78, 0.79, and 0.77. In the case of CPC at one month, the AUC for GCS was 0.82 and the AUCs for SMS of interns, MS and nurses were 0.74, 0.75, and 0.73, respectively.
Conclusion: The accuracy of SMS was equal to that of GCS for predicting outcome for adult stroke patients in
such parameters as mortality, intubation and CPC.
