摘要/Abstract

摘要： 通过调查,全面掌握上海市虹口区CT应用频率及受检者分布特征,为进一步做好医疗照射防护、指导CT检查的合理应用提供数据支撑。采用普查方法,制作统一调查表,CT检查项目包括头部、胸部、腹部、脊柱、骨盆、四肢、CT 介入及其他等8个检查部位,按照联合国原子辐射效应科学委员会(UNSCEAR)提出的年龄组划分方法,划分为≤16岁、16~40岁、＞40岁3个年龄组。调查数据优先从医疗机构信息系统获取2023年度(调查时段2022年10月1日—2023年9月30日)CT检查人次,其次选择人工记录,进一步统计后填入调查表格,使用Excel软件对数据进行汇总分析。虹口区共有11家医疗机构开展CT检查,其中三级医院3家,二级医院4家,一级医院1家,未定级医院3家,CT设备27台,每百万人口CT拥有量39.3台;2023年CT检查总人次共934 653,年应用频率为1 359人次/千人口,应用最多的扫描部位为胸部57.20%,占比高的前五位扫描部位(胸部、腹部、头部、四肢和脊柱)合计占比94.40%;2023年CT检查总体男女比例为0.96∶1,头部、胸部、腹部、脊柱、四肢等主要检查类型中受检者女性均略多于男性;各检查类型均显示年龄＞40岁受检者合计占比82.19%。2023年虹口区CT检查主要集中在二级和三级医院,受检者年龄以大于40岁为主,且女性受检者略多于男性,应用频率为上海市2016年应用频率304人次/千人口的4.5倍。因此,加强CT检查的正当性评估和防护最优化对降低不必要的辐射暴露风险显得尤为重要。

Abstract: To comprehensively know well the frequency of CT application and distribution characteristics of examinees in Hongkou District, Shanghai city, and to provide data support for further improving medical radiation protection and guiding the rational application of CT examination, a survey method was used to create a unified survey form. The CT examination items included 8 examination positions, including head, chest, abdomen, spine, pelvis, limbs, CT intervention, and others. According to the age group division method proposed by UNSCEAR, they were divided into 3 age groups: less than and equal to 16 years old, 16-40 years old, and over 40 years old. The survey data will be firstly obtained from the medical institution information system for the number of CT examinations from October 1, 2022 to September 30, 2023. Secondly, manual recording will be selected and further statistics will be filled in the survey form. Excel software will be used to summarize and analyze the data. A total of 11 medical institutions in Hongkou District conducted CT examinations, including 3 class-A hospitals, 4 secondary hospitals, 1 primary hospital, and 3 unclassified hospitals. There were 27 CT devices and 39.3 CT scans per million population. In 2023, the total number of CT scans was 934 653, with an annual application frequency of 1 359 person times per thousand population. The most commonly used scanning area was the chest, accounting for 57.20%, with the top five scanning areas totally accounting for 94.40%. The overall male to female ratio of CT scans in 2023 was 0.96∶1, with slightly more female examinees than male examinees in the main types of examinations such as head, chest, abdomen, spine, and limbs. All types of examinations showed that the total proportion of examinees over 40 years old accounted for 82.19%. In 2023, CT scans in Hongkou District were mainly conducted in secondary and class-A hospitals, with the majority of examinees being over 40 years old, slightly more female than male examinees. The frequency of application has increased by 4.5 times compared to the application frequency of 304 person times per thousand population in Shanghai in 2016. Therefore, it is particularly important to strengthen the justification assessment and protection optimization of CT examinations to reduce unnecessary radiation exposure risk.
