Insights
CT scan rates significantly increase during the transition from pediatric to adult care, nearly tripling in young adults. Understanding pediatricians' radiation reduction strategies could benefit all patients.
Area of Science:
- Medical Imaging
- Radiology
- Pediatric Care
Background:
- Minimizing radiation exposure is crucial for pediatric and young adult patients.
- The transition from pediatric to adult medical care represents a critical period for healthcare management.
Purpose of the Study:
- To investigate the demand for computed tomography (CT) scans in a general hospital.
- To analyze CT scan rates, particularly during the transition from pediatric to adult care.
Main Methods:
- An observational epidemiological study was conducted in a teaching hospital.
- CT scan data from 2009 to 2015 were analyzed.
- Age-stratified rates of CT scan utilization were the primary outcome measure.
Main Results:
- A total of 262,221 CT scans were performed.
- A substantial increase in CT scan rates was observed during the transition from pediatric to adult care.
- Individuals aged 19-24 years had significantly higher CT scan rates (19.8 per 1000 episodes) compared to those aged 10-15 years (6.7 per 1000 episodes).
Conclusions:
- CT scan utilization nearly triples during the transition from pediatric to adult care.
- Pediatricians' strategies for minimizing radiation exposure may offer valuable insights for adult physicians.
- Adopting these strategies could lead to reduced ionizing radiation exposure for all patients.
Objective:
Avoiding unnecessary radiation exposure is a clinical priority in children and young adults. We aimed to explore demand for CT scans in a busy general hospital with particular interest in the period of transition from paediatric to adult medical care.
Methods:
We used an observational epidemiological study based in a teaching hospital. Data were obtained on numbers and rates of CT scans from 2009 to 2015. The main outcome was age-stratified rates of receiving a CT scan.
Results:
There were a total of 262,221 CT scans. There was a large step change in the rate of CT scans over the period of transition from paediatric to adult medical care. Individuals aged 10-15 years experienced 6.7 CT scans per 1000 clinical episodes, while those aged 19-24 years experienced 19.8 CT scans per 1000 clinical episodes (p < 0.001). This difference remained significant for all sensitivity analyses.
Conclusion:
There is almost a threefold increase in rates of CT scans in the two populations before and after the period of transition from paediatric to adult medical care. While we were unable to adjust for case mix or quantify radiation exposure, paediatricians' diagnostic strategies to minimize radiation exposure may have clinical relevance for adult physicians, and hence enable reductions in ionizing radiation to patients. Advances in knowledge: A large increase in rates of CT scans occurs during adolescence, and considering paediatricians' strategies to minimize radiation exposure may enable reductions to all patients.

Computed Tomography
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...
