| 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350 221、71 597、327 404、23 820和12 849。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 350 221, fluoroscopy 71 597, CT 327 404, dental 23 820 and breast 12 849, respectively. The number of examinations per 1 000 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. |
