摘要目的:探索分层质控和专项质控在超声科质控管理中的应用效果。方法:应用分层质控和专项质控的方法分别从基础质控、深层质控、产筛质控、危急值质控四个方面对纳入质控范围的超声报告进行质控。探索分层质控、专项质控实施前、后报告合格率及临床综合满意度的变化。结果:实施分层质控和专项质控后基础质控、深层质控、产筛质控和危急值质控报告合格率均明显上升。临床综合满意度得分［（90.58±1.79）分］，高于实施前［（80.37±2.72）分］，差异有统计学意义（ P<0.01）。 结论:实施“分层质控”是提升超声报告质量和临床满意度的有效方法。

abstractsObjective:To explore the effect of the application of hierarchical and special quality control in the quality control management of an ultrasound department.Methods:The hierarchical and special quality control method was used to control ultrasonic reports that were related to four quality control areas: basic quality control, deep quality control, obstetrical quality control, and critical value quality control. Changes in the qualified reporting and comprehensive clinical satisfaction rates before and after the implementation of hierarchical and special quality control were examined.Results:After the implementation of hierarchical and special quality control, the qualified rates of basic quality control, deep quality control, obstetrical quality control, and critical value quality control increased significantly. The comprehensive clinical satisfaction score was (90.58±1.79) points, which was higher than before the model was applied [(80.37±2.72) points], and the difference was statistically significant ( P<0.01). Conclusion:The implementation of hierarchical and special quality control measure can effectively improve the quality of ultrasonic diagnoses and comprehensive clinical satisfaction.
