Outcome of Trauma Patients Admitted to Emergency Department Based on Full Outline of Unresponsiveness Score
Introduction: Full Outline of Unresponsiveness (FOUR) score is one of the existing scoring scales, which has been used for evaluating the level of consciousness in recent years. Objective: The present study has been done with the aim of evaluating the ability to predict the outcome of patients with head trauma based on FOUR score on admission to emergency department (ED). Methods: In the present prospective cross-sectional study, head trauma patients with any changes in alertness level presenting to ED were evaluated. FOUR score measurement was done on admission and 6 hours after that. The studied outcomes in the current study included discharge without sequel, discharge with neurologic sequel, brain death or death during 1 month after admission of the patients. To evaluate the correlation between FOUR score and the studied outcomes, area under the receiver operating characteristic (ROC) curve was used. Results: In the end, 52 patients with the mean age of 32.67 ± 15.20 years were evaluated (84.6% male). Traffic accident with the frequency of 39 (75.0%) patients was the most common mechanism of trauma among the studied patients and finally, after 1 month follow up it was determined that 13 (25%) patients were discharged without sequel and 31 (59.6%) died. Area under the ROC curve for prediction of the final outcome of death using FOUR score on admission and after 6 hours were 0.889 (95% confidence interval: 0.800 - 0.977) and 0.974 (95% confidence interval: 0.938 – 1.000), respectively. Best cutoff points for FOUR score were the scores 8 and 9 on admission of the patients, and the score 5, six hours after admission. Conclusion: Based on the findings of this study, it seems that FOUR score is applicable for prediction of probable death outcome in patients with head trauma presenting to ED.
