Abstract
Background-Clinical information collected at baseline can be useful in knowing the clinical
trends of mild head injury. One of the constraints of managing mild head injury patients is the
availability and proper use of computed tomography scans. This clinical trend can be used to
identify patients who need imaging after mild head injury. As a sub analysis, we compared
the Canadian head computed tomography rule with the New Orleans criteria to select
patients who need computed tomography scans for Ethiopian mild head injury patients.
Objective- The objective of this study is to see the clinical trends and computed
tomography scan findings of mild head injury patients.
Method- A retrospective observational study of adult mild head injury patients who were
seen at the Tikur anbesa specialized hospital. emergency room from December 2018 to July
2021. The study population was adult mild head injury patients who got head computed
tomography scans after evaluation at the Tikur anbesa specialized hospital emergency room.
The data will be collected from patients' charts using a structured checklist prepared by the
investigator. SPSS software version 26 was used. Bivariate and multivariable logistic regression
analyses were performed to identify factors associated with abnormal CT scan findings. Pvalue
<
0.05
was
used
to
declare
statistical
significance.
Result- patients met the criteria for this study and analyzed. The highest frequency of head
injury occurred in the 20 to 29 age group (49.2%). The incidence of mild head injury was higher
in males 166(86%). mild head injury patient tends to come slightly more at night shift (51%).
the most common referral source was self-referral (39.9%). The number of abnormal CT scan
findings seen was 58(30.1%). The most common CT scan finding was skull fracture 44(75.8%).
sensitivity of CCHR and NOC rule is 100% and CCHR has higher specificity than NOC rule. Being
male, regional referral source, tachycardia, and falling down mechanism of injury were found
to be a predictor of abnormal CT scan findings.
Conclusion: The clinical trends of MHI patient is very important to determine the eligibility
of mild head injury patients for CT scan.
