In the present study, the most common mechanism for trauma was found as falling in accordance with the later study. Assault was the second and motor vehicle accidents were the third most common mechanisms of trauma. Our hospital is in the center of the city, and away from the high ways. This may be the reason for motor LY2874455 vehicle accidents to be the third most common cause. The mechanism of trauma is probably depends on the distance from
hospital to high ways, social and economical status and degree or level of hospital as trauma centre. Similar to prior studies, males were the most affected sex group from the trauma in the present study [3, 4, 13]. This is probably due to men’s working in more dangerous jobs, taking more places in active city social life, being more associated with violence and male drivers being more than females. In the present study, efficacy of both criteria were found similar in the patients having GCS score 13. In the patients having GCS score 14–15, a comparison
of the clinical decision rules for use of CT in patients with MHI showed that both the CCHR and the NOC were sensitive for the outcome measure of any traumatic intracranial lesion on CT which is “clinically YH25448 important” brain lesion. Although the sensitivity was high in these two decision rules, they both had much lower sensitivities in this study than the original published studies [3, 13–15]. Papa et al. and Smits et al. found sensitivities of both rules to reach 100% [13, 15]. The cause of lower sensitivities may be explained by our patients’ low socioeconomic status and unreliable history. In contrast to previous publications, Ro et al. found lower sensitivities in both decision rules similar to our study results. They also found the sensitivity higher in NOC and specificity higher in CCHR . In the present study, the Non-specific serine/threonine protein kinase specificity of CCHR was higher than specificity of NOC (47,1% versus 6.9%). Our results were similar to the results of the study
reported by Smits et al. They found the specificity of CCHR higher than the specificity of NOC (39.7% versus 5.6%) . Papa et al. and Stiell et al. also found the specificity of CCHR higher than NOC [3, 15]. In the present study, CCHR was found to be superior to NOC due to higher specificity, higher PPV and NPV. The only superiority of NOC in our study was the sensitivity with 88.2% while it was 76.4% in CCHR. Many prior studies also found the sensitivity of NOC higher than the sensitivity of CCHR [13, 16]. Smits et al. tried to explain this difference in sensitivities for neurocranial traumatic CT findings between the 2 decision rules with more stringent use of the risk factor of external injury in the CCHR. For example in the NOC, this risk factor comprises all external injuries above the clavicles. Despite the NOC having higher sensitivity, specificities for neurocranial traumatic CT findings were low for the NOC decision rule, and higher for the CCHR . In accordance with Smits et al.
