This is a retrospective study of patients diagnosed with acute ischemic or hemorrhagic stroke admitted to a single comprehensive stroke center from January 2018 to October 2023. Data on demographics, initial MEWS, NIHSS, neurological deterioration, and mortality at 12 months were collected. Descriptive and logistic regression analyses were performed. Correlations between continuous variables were calculated using Pearson correlation coefficient. Significance was defined as a p-value <0.05.

A total of 103 patients were included (mean age 70±15.3), 48.5% of which were female. 75.7% of the patients had low MEWS (0-2), 15.5% had moderate MEWS (3-4), and 8.7% had a high MEWS (>5). Patients with a high MEWS had a higher 1-year mortality rate (OR 7.14, 95 % CI: 1.71–29.9, p=0.003) and were more likely to develop neurologic deterioration after the hospital admission (OR 15.9, 95 % CI: 3.02–83.1, p<0.001). There were strong positive correlations between initial MEWS and NIHSS (Pearson's r 0.761, p<0.001), and initial MEWS and modified Rankin Scale at 90 days (Pearson's r 0.589, p<0.001).
