Insights
A quality improvement initiative reduced cranial computed tomography (CT) use in children with minor head injuries. This strategy lowered CT scans without increasing missed significant head injuries, improving pediatric emergency care.
Area of Science:
- Pediatric Emergency Medicine
- Radiology Quality Improvement
- Traumatic Brain Injury Diagnosis
Background:
- Blunt head trauma is common in children, but cranial computed tomography (CT) use for diagnosis carries malignancy risks.
- Cranial CT is the standard for diagnosing traumatic brain injury (TBI) in children.
- Reducing unnecessary CT scans in pediatric head trauma is a key quality improvement goal.
Purpose of the Study:
- To decrease the utilization of cranial CT scans in pediatric patients with minor head injuries.
- To evaluate the effectiveness of a quality improvement initiative on CT use.
- To ensure reductions in CT scans do not compromise the detection of significant head injuries.
Main Methods:
- Implementation of a multifaceted quality improvement initiative in the emergency department (ED).
- Development and application of an evidence-based guideline for minor blunt head trauma evaluation.
- Inclusion of individual provider feedback and use of statistical process control for monitoring CT rates.
Main Results:
- A total of 6851 ED visits were analyzed, with 62% in the post-implementation period.
- Cranial CT rates decreased from a baseline of 21% by an absolute 6% after guideline implementation and another 6% after provider feedback.
- No increase in hospital admissions within 72 hours for missed significant head injuries was observed.
Conclusions:
- A quality improvement program combining an evidence-based guideline and provider feedback effectively reduced cranial CT use in children with minor head trauma.
- The initiative demonstrated a significant decrease in CT scans without compromising patient safety or missing critical injuries.
- This approach offers a successful model for optimizing diagnostic imaging in pediatric emergency settings.
Objective:
Blunt head trauma is a common injury in children, although it rarely requires surgical intervention. Cranial computed tomography (CT) is the reference standard for the diagnosis of traumatic brain injury but has been associated with increased lifetime malignancy risk. We implemented a multifaceted quality improvement initiative to decrease the use of cranial CT for children with minor head injuries.
Methods:
We designed and implemented a quality improvement effort that included an evidence-based guideline as well as individual feedback for children aged 0 to 21 years who present to the emergency department (ED) for evaluation of minor blunt head trauma. Our primary outcome was cranial CT rate, and our balancing measure was any return to the ED within 72 hours that required hospitalization. We used statistical process control methodology to measure cranial CT rates over time.
Results:
We included 6851 ED visits of which 4242 (62%) occurred in the post-guideline implementation period. From a baseline CT rate of 21%, we observed an absolute reduction of 6% in cranial CT rate (95% confidence interval 3% to 9%) after initial guideline implementation and an additional absolute reduction of 6% (95% confidence interval 4% to 8%) after initiation of individual provider feedback. No children discharged from the ED required admission within 72 hours of initial evaluation.
Conclusions:
An ED quality improvement effort that included an evidence-based guideline as well as individual provider feedback was associated with a reduction in cranial CT rates without an increase in missed significant head injuries.
