Brain CT-scan was performed in all the patients. Kappa Coefficient was used to determine the ratio of agreement of the CT indications (+ and ⎼) and multiple logistic regression to determine the relative odds of positive CTs.Results: Overall we included 610 patients. One-hundred and one patients (16.5%) had positive and 509 (83.5%) had negative CT findings. Of positive CTs, the highest percentage was dedicated to high-energy mechanism of trauma. High-energy trauma mechanism (OR=1.056, 95% CI, OR, 1.03-1.04, P<0.001), superior injury of clavicle (OR=1.07, 95% CI, OR, 1.03-1.1, P<0.001) and moderate to severe headache (OR=1.04, 95% CI, OR, 1.02-1.05, P<0.001) were positive predictors of CT findings. The combined mean of positive symptoms equaled 0.29 ± 0.64 in negative CTs, but 5.13 ± 2.4 in positive CTs, showing a significant difference. (P<0.001)Conclusion: Abnormal positive brain CT in victims with mild TBI is predictable if one or several risk factors are taken into account such as moderate to severe headache, decreased consciousness, skull fracture, high-energy trauma mechanism, superior injury of clavicle and GCS of 13-14. The more the symptoms, the more likely the positive CT results would be.
