This study evaluated the rates and annual trends of pediatric CT scans in South Korea using a nationwide population-based database.
Data regarding pediatric CT scan usage between 2012 and 2017 were retrieved from the health insurance review and assessment service. Data on the age, sex, diagnosis, and the anatomical area of involved patients were also extracted.
A total of 576376 CT examinations were performed among 58527528 children aged below 18 years (9.8 scans/1000 children), and the number of CT examinations per 1000 children was noted to have increased by 23.2% from 9.0 in 2012 to 11.0 in 2017. Specifically, the number of CT examinations increased by 32.9% for the 6-12 years of age group (7.4/1000 to 9.8/1000) and by 34.0% for the 13-18 years of age group (11.4/1000 to 15.3/1000). Moreover, majority of the CT scans were limited to the head (39.1%), followed by the extremities (32.5%) and the abdomen (13.7%). Notably, the number of extremity CT scans increased by 83.6% (2.3/1000 to 4.2/1000), and its proportion as compared to other scans increased from 25.3% to 37.7%.
CT scans in the pediatric population increased continuously from 2012 to 2017 at an annual rate of 4.4%. Therefore, physicians should balance the benefits of CT with its potential harms from associated radiation exposure in pediatric patients.
本研究利用全国性的基于人群的数据库评估了韩国儿科CT扫描的使用率及年度趋势。
从健康保险审查和评估服务机构检索了2012年至2017年间儿科CT扫描使用情况的数据。还提取了有关患者年龄、性别、诊断及受累解剖部位的数据。
在58527528名18岁以下儿童中总共进行了576376次CT检查（9.8次扫描/1000名儿童），并且每1000名儿童的CT检查次数从2012年的9.0次增加到2017年的11.0次，增幅为23.2%。具体而言，6至12岁年龄组的CT检查次数增加了32.9%（从7.4/1000增加到9.8/1000），13至18岁年龄组增加了34.0%（从11.4/1000增加到15.3/1000）。此外，大多数CT扫描局限于头部（39.1%），其次是四肢（32.5%）和腹部（13.7%）。值得注意的是，四肢CT扫描次数增加了83.6%（从2.3/1000增加到4.2/1000），其与其他扫描相比的比例从25.3%增加到37.7%。
2012年至2017年间儿科人群的CT扫描以每年4.4%的速度持续增加。因此，医生应权衡CT的益处及其对儿科患者相关辐射暴露的潜在危害。
