To discuss the repeated CT scanning in patients with traumatic brain injury (TBI) and to identify the conditions under which this approach is necessary.


One hundred and seventy-one patients who suffered TBI but were not surgically treated were divided into two groups: the routine-repeat CT group (n = 89) and the non-routine-repeat CT group (n = 82). The patients' clinical characteristics were compared. T-tests and stepwise logistic regression were used for analysis. Patients in the routine-repeat CT group were divided into three groups according to GCS scores to determine the need for routinely repeated CT scans.


The results revealed statistically significant differences between the two groups in terms of neuro-ICU-LOS and LOS (p < 0.01). No significant differences emerged with respect to hospital charges and GCS scores at discharge (p > 0.05). AGE, international normalized ratio (INR), D-dimer concentration (DD), GCS scores and number of hours between the first CT scan and the injury (HCT1) were influential factors of developing progressive haemorrhage.


The routine-repeat CT group fared better than did the non-routine-repeat CT group. Routinely repeated CTs were minimally effective among those with mild TBI, whereas this procedure demonstrated a significant effect on patients with moderate and severe TBI.
