Insights
Pediatric trauma evaluations involve significant radiation exposure, particularly for high-acuity cases and those involving outside hospital imaging. Understanding radiation doses is crucial for identifying at-risk populations and optimizing imaging protocols in pediatric trauma care.
Area of Science:
- Pediatric radiology
- Trauma imaging
- Radiation dose assessment
Background:
- Current pediatric trauma radiation exposure data is based on estimates, not actual clinical measurements.
- Lack of precise baseline radiation exposure data hinders accurate risk assessment in pediatric trauma evaluations.
Purpose of the Study:
- To determine the actual baseline radiation exposure during pediatric trauma evaluations.
- To correlate radiation exposure with trauma activation status to identify high-risk patient groups.
Main Methods:
- Retrospective analysis of 1050 pediatric trauma patients at a Level I children's hospital (June 2010-January 2011).
- Focused on 215 patients with complete dosimetry data, analyzing demographics, injury severity, imaging modalities, and total effective radiation dose.
- Compared radiation doses across different trauma activation levels (consults, alerts, stats).
Main Results:
- CT scans contributed the most radiation, with highest doses observed in 'stat' activations, followed by 'alerts' and 'consults'.
- Repeated imaging was frequent; 35% of 'stat' activations had 2-3 CTs, and 40% had 4-10 CTs.
- Outside hospital CTs often exceeded standard pediatric radiation doses, with 50% delivering at least double the recommended amount.
Conclusions:
- This study provides the first actual baseline of radiation exposure in pediatric trauma evaluations.
- Higher radiation doses are associated with 'stat' activations, suspected non-accidental trauma (NAT), and imaging performed at outside hospitals.
- Findings highlight the need for standardized protocols to manage radiation exposure in pediatric trauma care.
Background:
The actual baseline of radiation exposure used in evaluating pediatric trauma is not known and has relied on estimates in the literature that may not reflect clinical reality. Our objectives were to determine the baseline amount of radiation delivered in a pediatric trauma evaluation and correlate radiation exposure with trauma activation status to identify the cohort most at risk.
Methods:
We retrospectively evaluated trauma patients (N = 1050) at an independent Level I children's hospital for each level of trauma activation (consults, alerts, stats) from June 2010 to January 2011. Those patients with full dosimetry (N = 215) were analyzed for demographics, mechanism of injury, Injury Severity Score, imaging modalities, and total effective radiation dosages during the full trauma assessment from the time of injury to discharge.
Results:
Demographics included gender (143 males, 72 females) and average age (5.5 years [range < 1-16]). The most radiation was conferred from CTs and greatest in trauma stats, followed by alerts, then consults (p < 0.001 for stat and alert doses compared to consults). Repeated imaging was common: 35% of stats had 2-3 CTs and 40% had 4-10 CTs (range 0-10 CTs). The average non-accidental trauma consult utilized four times as many CTs as the average consult (p = 0.002). Most outside hospital CTs (66%) delivered more radiation: 50.0% were at least double the standard pediatric dosage.
Conclusions:
This study is the first to identify the actual baseline of radiation exposure for one trauma evaluation and correlate radiation exposure with trauma activation status. Factors associated with highest radiation include stat activations, suspected non-accidental traumas (NAT), and outside hospital system imaging.
