摘　　要：目的分析医用X射线诊断应用的分布特征,估算淮安市的应用频度。方法采用分层随机抽样,选择淮安市三级医院2家(1家综合和1家妇幼)、二级医院4家、一级及以下医院20家,调查2017年26家医院医用X射线诊断应用情况。结果三级、二级、一级及以下医院的平均X射线诊断设备数量分别为13.5、7.3、1.6台,进口设备占比分别为85.2%、69.0%、9.4%,医院级别越高,役龄5年以内设备占比越大;26家医疗机构的2017年X射线摄影、透视、CT、口腔和乳腺检查人次分别为350221、71597、327404、23820和12849。初步估算得到淮安市2017年常规X射线诊断频度约为444.22人次/千人口、CT检查为236.40人次/千人口。结论淮安市常规X射线诊断频度低于2016年江苏省平均水平,CT诊断频度与江苏省平均水平基本一致,较"九五期间"江苏省平均水平增长较快。Objective To estimate the frequencies of medical X-ray diagnositic examinations and analyze their distribution in Huai'an City.Methods Stratified random sampling was used to select 2 tertiary hospitals including 1 general hospital and 1 MCH hospital,4 secondary hospitals,20 primary and unclassified hospitals to investigate medical X-ray examination frequencies in the 26 hospitals in 2017.Results The average number of X-ray diagnostic equipment were 13.5 pieces in tertiary hospitals,7.3 in second-level hospitals and 1.6 in primary and ungraded hospitals.The fraction of imported equipment accounted for 85.2%,69.0%and 9.4%,respectively.The higher the hospital level,the greater the proportion of equipment with five years of service history.The number of examinations in 2017 in the 26 hospitals were X-ray photography 350221,fluoroscopy 71597,CT 327404,dental 23820 and breast 12849,respectively.The number of examinations per 1000 population were estimated to be 444.22 by conventional X-ray and 236.40 by CT.Conclusions The frequency of conventional X-ray examinations in the city is slightly lower than the average level in Jiangsu province in 2016 and the CT examination frequency is roughly same as in Jiangsu province.
