Risk assessment of mild traumatic brain injury with the King-DevickTest_in an emergency department sample

Abstract

King-Devick Test is one of the fastest primary evaluation tests for patients after minor head trauma. In this method, using 3 cards with different shapes on it, the speed of naming different objects is performed by the person in charge. The process takes about 2 minutes to complete, in which the person is disturbed by eye movement, attention, and the ability to speak properly is evaluated. Materials and Method: In this study, 148 patients with minor head trauma were entered into the study and were subjected to King-Devic test in two stages at the time of discharge and during discharge. The results were obtained in the patients. Results: The number of participants in this study was 148, of which 55 (37.2%) were female and 93 (62.8%) were male. The mean age of participants in this study was 31.67 years with a standard deviation of 10.33 years, with the lowest age among the patients 15 years and 63 years of age. The study of patients' education showed that the mean of study years in the current study was 15 years with a standard deviation of 2.2 years. Among the people, the lowest level of education was 9 years and the highest level of education was 18 years. The mean score of the primary and secondary K-D tests was compared with the pair t-test. The results showed that the mean scores of primary and secondary K-D tests were significantly different at the significance level of 95%. (P-value = 0.00). The results of K-D test in two primary and secondary conditions were also investigated by intergroup analysis of the CT result. The results showed that time factor in the whole process of data was significant (p-value = 0.008). Meanwhile, the mean K-d test points changed significantly over time, but with the significance of the interactive effect (time * CT results grouping) with (p-value = 0.002), the effect of time in the three groups was significantly different. In other words, over time, there is no similar effect on the mean scores of the three groups.
