基于卫生健康信息平台的上海市金山区放射学影像检查现状调查

Investigation on current radiological examinations in Jinshan district of Shanghai based on the health information platform

目的了解金山区医疗机构放射诊疗特征及重复检查情况,为正确引导合理实施各种医疗照射,提出策略和建议。方法通过上海市卫生健康委员会信息中心平台获取金山区医疗机构2017年的放射学影像检查个案数据,分析受检者的人群分布、检查类型、检查部位、诊断疾病等特征,并对其重复检查、检查结果情况进行分析。结果金山区放射学影像检查的主要类型是CT检查和常规X射线诊断检查,分别占到总检查人次数的53.2%和44.7%;放射学影像检查受检者主要为本市户籍(77.3%),检查人次数男性49.4%,女性50.1%,男、女检查频次相当;CT和常规X射线诊断检查人次数最多的是≥41岁年龄组,分别占到77.1%和65.2%。金山区医疗机构CT检查的主要部位分别是胸部(32.8%)、腹部(19.4%)、脑(16.1%)、脊柱(11.4%);常规X射线诊断检查的主要部位是胸部(43.2%)和四肢(39.6%)。放射学影像检查主要申请科室是外科(39.7%)和内科(27.1%),主要因呼吸系统疾病(19.8%)、损伤、中毒和外因的某些其他后果(15.8%)、肌肉骨骼系统和结缔组织疾病(15.8%)等接受放射学影像检查。常规X射线诊断检查阳性率是53.1%,CT检查阳性率是73.5%。常规X射线诊断、CT重复检查的比例较高,分别占到该类型检查人次数的9.3%和7.9%。结论金山区CT检查占到放射学影像检查总频次的一半以上,可针对特定的医生及患者类型进行放射学影像检查使用的干预。

Objective To investigate the characteristics of diagnostic radiology and the situation of repeated examinations at medical institutions of Jinshan district,and put forward strategies and suggestions for the correct guidance on and reasonable applications of various medical exposures.Methods The cases data on radiological examinations at medical institutions in Jinshan district,obtained in 2017 from Shanghai Municipal Health Commission Information Center Platform,was used to describe the characteristics of population distribution of patients,examination types,examination areas,diagnosed diseases,number of repeated examinations and the result of radiological examinations.Results The main types of radiological examinations in Jinshan district were the CT scans and the conventional X-ray diagnosis,accounted respectively for 53.2%and 44.7%of the total radiological examinations.The radiological examinations were mainly performed on household registration(77.3%).The number of radiological examinations on males was close to on females,with examination frequency of 49.4%for males and 50.1%for females.The greatest frequency of radiological examinations was found in the age group older than 41 years,accounting for 77.1%of CT scans and 65.2%of the conventional X-ray diagnosis.The main examination sites of the CT scans at Jinshan medical institutions were chest(32.8%),abdomen(19.4%),brain(16.1%)and spine(11.4%),and for the conventional X-ray diagnosis were chest(43.2%)and limbs(39.6%).The main departments applying for radiological examinations are surgery(39.7%)and medicine(27.1%).The numbers of radiological examinations are,respectively,diseases of the respiratory system(19.8%),the injury,poisoning and some other consequences of external causes(15.8%),and the diseases of musculoskeletal system and connective tissue(15.8%).The positive rate of the conventional X-ray diagnosis was 53.1%,and the positive rate of CT scans was 73.5%.The conventional X-ray diagnosis and CT scans contributed higher specific rates of repeated examinations,accounting for 9.3%and 7.9%of the total of such type examination,respectively.Conclusions CT scans in Jinshan district accounted for more than half of the total frequency of radiological examinations,therefore,interventions should be imposed on certain types of phycians and patients types.
