Insights
An observation unit (OU) in the emergency department significantly reduced computed tomography (CT) scans for pediatric patients with minor blunt head trauma. This initiative lowered CT use by 30%, avoiding unnecessary radiation exposure.
Area of Science:
- Emergency Medicine
- Pediatric Radiology
- Health Services Research
Background:
- Minor blunt head trauma in children often leads to computed tomography (CT) scans.
- Overutilization of CT scans in pediatric patients raises concerns regarding radiation exposure and healthcare costs.
Purpose of the Study:
- To assess the impact of an emergency department observation unit (OU) on reducing unnecessary CT scans for pediatric patients with minor blunt head trauma.
- To evaluate the effectiveness of an OU in optimizing diagnostic imaging practices for pediatric head injuries.
Main Methods:
- A retrospective before-and-after study design was employed.
- Pediatric patients (≤18 years) with minor blunt head trauma and Glasgow Coma Scale scores of 14-15 were analyzed.
- Head CT utilization rates were compared before and after the implementation of the OU.
Main Results:
- A total of 4706 pediatric patients were included in the analysis.
- Head CT use decreased from 5.7% before OU institution to 4.0% after (P = 0.01).
- The relative risk reduction in CT use was 0.70, indicating a 30% decrease.
Conclusions:
- The establishment of an observation unit in the emergency department effectively reduced the rate of head CT scans for pediatric minor head injuries.
- The OU serves as a valuable strategy for avoiding unnecessary CT imaging in this patient population, mitigating radiation risks.
Objective:
The aim of this study was to evaluate the effect of an observation unit (OU) in an emergency department on reducing unnecessary use of computed tomography (CT) for minor blunt head trauma.
Methods:
This study was a retrospective before-and-after study of pediatric patients 18 years or younger with minor blunt head trauma. Patients with a Glasgow Coma Scale score of 14 or 15 who presented to the emergency department were included in the analysis. The rates of head CT use in the period before and after the institution of the OU were compared.
Results:
In total, 4706 patients were analyzed (2344 from the period before and 2362 from period after OU institution). The median age of the patients was 3 years, and 64% were male in each period. The rates of CT use were 5.7% (95% confidence interval [CI], 4.8%-6.7%) in the period before and 4.0% (95% CI, 3.3%-4.9%) in the period after OU institution (P = 0.01). The relative risk reduction was 0.70 (95% CI, 0.54-0.91).
Conclusions:
The rate of CT use decreased by 30% as a result of OU institution. The OU was an effective means of avoiding an unnecessary head CT for pediatric minor head injuries.

Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
