摘要:
目的 通过对天津市6个行政区内172台医用X射线摄影机质量控制检测,了解天津市6个行政区医用X射线摄影机的性能指标状况。方法 根据医院级别和性质将医疗机构分为三级医院、二级医院、一级医院和民营医院,按照《医用常规X射线诊断设备影像质量控制检测规范》(WS 76—2011)标准对其中共性的9项指标进行检测,9项指标均合格的设备被判定为合格。采用SPSS16.0软件进行统计学分析。多组样本组间率的比较采用R×C列联表的χ2检验,多组样本间率的两两比较采用χ2分割法。结果 在172台设备中,合格的设备占69.2%;不合格指标主要是管电压指示的偏离和光野与照射野四边的偏离。三级医院设备合格率为82.4%,高于一级医院的51.9%和民营医院的54.1%,差异有统计学意义(χ2=9.272、9.599,均P<0.01);三级医院国产设备占有率为7.35%,低于二级医院的27.5%、一级医院的92.6%和民营医院的78.4%,差异有统计学意义(χ2=7.907、64.184、54.478,均P<0.01);二级医院国产设备占有率也低于一级医院和民营医院,差异有统计学意义(χ2=27.472、19.932,均P<0.01);在用设备使用年限大于10年的,三级医院占16.2%,低于一级医院的51.9%,差异有统计学意义(χ2=12.933,P<0.01)。结论 天津市6个行政区二级、三级医院医用X射线摄影机性能状态良好,一级和民营医院需进一步优化设备和加强质量控制管理。
Abstract:
Objective To understand the performance indicators of radiography unit in six district of Tianjin. We tested and analyzed the testing results of 172 radiography unit in the light of quality control inspection and evaluation methods. Methods The medical institution was divide into tertiary hospital, secondary hospital, community hospital and private hospital. We tested the nine indexs of radiography unit with the Specifications for Testing of Image Quality Control in Medical X-ray Diagnostic Equipment(WS 76-2011). And only when the nine index were qualified, the radiography unit was judged to be qualified. All date were analysed by SPSS 16.0. Multi-sample rate was done by R×C Chi-square test, and multiple comparisons of rate was done by partition of Chi-square test method. Results The qualified rate of the 172 units were 69.2%. The unqualified indexs of radiography unit were the deviation of the pipe voltage indicator and the deviation of the light field from the four sides of the irradiation field. The qualified rate of state testing in tertiary hospital was 82.4%, which was higher than that 51.9% in community hospital and 54.1% in private hospital(χ2=9.272, 9.599, both P<0.01), and these differences were all statistically significant. The occupancy rate of domestic radiography unit in tertiary hospital was 7.35%, which were lower than that 27.5% in secondary hospital, that 92.6% in community hospital and that 78.4%(χ2=7.907, 64.184, 54.478, all P<0.01) in private hospital, and these differences were all statistically significant. And the occupancy rate of domestic radiography unit in secondary hospital were lower than that in community hospital and private hospital(χ2=27.472, 19.932, both P<0.01), and these differences were all statistically significant. The rate of radiography unit used by tertiary hospitals over 10 years was 16.2%, which was lower than that 51.9%(χ2=12.933, P<0.01) in community hospital, and this difference was statistically significant. Conclusion The performance status of radiography unit in tertiary hospital and secondary hospital of the six district of Tianjin are satisfactory, wherea community hospitals and private hospital need to optimize radiography unit and strengthen quality control management.
