Aim:
Our primary aim was to calculate the head computed tomography (CT) scan rate in children with a minor head injury (MHI) when the Dutch National guidelines were followed in clinical practice. The secondary aim was to determine the incidence of CT abnormalities and the guideline predictors associated with traumatic abnormalities.
Methods:
We performed a multi-centre, prospective observational cross-sectional study in the emergency departments of six hospitals in The Netherlands between 1 April 2015 and 31 December 2016.
Results:
Data on 1002 patients were studied and 69% of cases complied with the guidelines. The overall CT rate was 44% and the incidence of traumatic abnormal CT findings was 13%. CT scans were performed in 19% of children under two years of age, 48% of children between two and five years and 63% of children aged six years or more. Multivariate regression analysis for all age categories showed that CT abnormalities were predicted by a Glasgow Coma Scale of less than 15, suspicion of a basal skull fracture, vomiting and scalp haematomas or external lesions of the skull.
Conclusion:
Strict adherence to the Dutch national guidelines resulted in CT overuse. New guidelines are needed to safely reduce CT scan indications.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Timely documentation is crucial to ensure continuity of care for patients. Any delays in recording or reporting medical information can result in medical errors and even adverse patient outcomes. From medication administration to diagnostic test results, every detail must be accurately and promptly documented to provide the best possible care for patients.
