Abstract

PURPOSE
We wanted to evaluate the utility of the Simplified Motor 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. Each 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.
