Background: The management of minor head injury (GCS score of 15) especially in the use of computed tomography (CT) scan is still controversial. As a big and developing country, Indonesia faced some problems in the management of minor head injuries. Those problems were limited number of CT scan, big number of minor head injured patients assessed in emergency unit and far distance between small cities and referral centers. This study was aimed to provide different approaches in obtaining CT scan in this group of patients.

Methods: This was a cohort prospective study involving 364 head injured patients with a GCS score of 15, aged over six years. All studied clinical data were recorded and CT scan was obtained. The relationship between the clinical risk factors and the presence of abnormal CT scan (the first end point of this study) and the need for surgery (the second end point) were tested by univariate analysis ((X2-test). Logistic regression analysis was then used to find the best combination of these clinical factors that were highly sensitive to detect abnormal CT scan and the need for surgery.

Results: The incidence of abnormal CT scan and the need for surgery were 13.2% and 3.7% respectively. Loss of consciousness (LOC) (RR 4.84, 95 % CI 1.29 - 18.13), amnesia (RR 4.45, 95% CI 1.86 - 10.68), cranial soft tissue injury (RR 8.56, 95% CI 3.43 - 21.46), skull fracture (RR 6.81, 95% CI 2.04 - 22.77), age > 60 years (RR 5.56, 95% CI 2.09 - 14.77) were significant clinical factors of abnormal CT scan. While amnesia (RR 0.068, 95% CI 0.007 - 0.626), cranial soft tissue injury (RR 0.076, 95% CI 0.009 - 0.647) and skull fracture (RR 0.145, 95% CI 0.035 - 0.607) were significant clinical factors of the need for surgery.

Conclusion: Our recent study provided two different approaches in obtaining head CT scan in minor head injuries, which were dependent on the availability of CT scan and the aim of taking CT scan.
