Insights
Cervical spine CT (CSCT) use increased significantly in pediatric trauma patients over a decade, particularly in general emergency departments (GEDs) compared to pediatric trauma centers (PTCs). This rise occurred despite stable rates of cervical spine injury (CSI).
Area of Science:
- Pediatric Emergency Medicine
- Radiology
- Trauma Surgery
Background:
- Pediatric trauma guidelines recommend cervical spine CT (CSCT) for suspected injuries on plain radiographs.
- Variations in CSCT utilization between specialized pediatric trauma centers (PTCs) and general emergency departments (GEDs) are not well understood.
Purpose of the Study:
- To compare the utilization rates of CSCT between PTCs and GEDs for pediatric trauma patients.
- To identify factors associated with CSCT use in this population.
Main Methods:
- Analysis of a pediatric trauma registry from 2002 to 2011.
- Comparison of CSCT and cervical spine injury (CSI) rates in PTCs versus GEDs.
- Multivariate logistic regression to assess factors influencing CSCT use.
Main Results:
- Over 5100 patients were analyzed; GED patients had higher injury severity scores and ICU admission rates.
- The overall CSI rate remained stable at 2.1%.
- CSCT utilization increased significantly over time in both settings, with notably higher and increasing rates in GEDs (6.8% to 42.0%) compared to PTCs (3.5% to 16.1%).
Conclusions:
- Despite stable CSI rates, CSCT utilization has markedly increased in pediatric trauma care.
- Initial evaluation at a GED is strongly associated with higher CSCT use.
- Further research may be needed to optimize CSCT utilization guidelines in pediatric trauma.
Background:
Guidelines for evaluating the cervical spine in pediatric trauma patients recommend cervical spine CT (CSCT) when plain radiographs suggest an injury. Our objective was to compare usage of CSCT between a pediatric trauma center (PTC) and referral general emergency departments (GEDs).
Methods:
Patient data from a pediatric trauma registry from 2002 to 2011 were analyzed. Rates of CSI and CSCT of patients presenting to the PTC and GED were compared. Factors associated with use of CSCT were assessed using multivariate logistic regression.
Results:
5148 patients were evaluated, 2142 (41.6%) at the PTC and 3006 (58.4%) at the GED. Groups were similar with regard to age, gender, GCS, and triage category. GED patients had a higher median ISS (14 vs. 9, p<0.05) and more frequent ICU admissions (44.3% vs. 26.1% p<0.05). CSI rate was 2.1% (107/5148) and remained stable. CSCT use increased from 3.5% to 16.1% over time at the PTC (mean 9.6% 95% CI=8.3, 10.9) and increased from 6.8% to 42.0% (mean 26.9%, CI=25.4, 28.4) at the GED. Initial care at a GED remained strongly associated with CSCT.
Conclusions:
Despite a stable rate of CSI, rate of CSCT increased significantly over time, especially among patients initially evaluated at a GED.

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...
