Comparison of the accuracy of Glasgow Coma Scale and Full Outline of Unresponsiveness Score in predicting the prognosis of patients with cerebrovascular accidents admitted to intensive care unit

BACKGROUND: Vascular-cerebral dysfunction is a sudden decline in brain function as a result of impaired blood supply to the brain. Critical care professionals in intensive care units (ICUs) need highly reliable prognostic scales to determine the degree of neurological dysfunction. The purpose of this study was to compare the Full Outline of Unresponsiveness (FOUR) Score and Glasgow Coma Scale (GCS) in predicting the prognosis of patients with cerebrovascular events. METHODS: This study was performed on forty patients with cerebrovascular accident (CVA). Researchers used the FOUR Score and GCS for mortality prediction for each patient. Descriptive statistics were used for data analysis. Mann-Whitney test was used for comparison of means. Data were analyzed using Stata software. RESULTS: In this study, according to FOUR Score, 62.5% of all patients survived and 37.5% died. Mean mortality and survival rates for GCS criterion were 5.37 ± 2.37 and 9.12 ± 2.12, respectively, and for FOUR Score criterion were 5.60 ± 0.81 and 10.64 ± 2.23, respectively. CONCLUSION: The FOUR Score has higher sensitivity, specificity, and predictive power than GCS in patients with CVA. Therefore, it is recommended to use this scale in ICUs.
