分析超声科"危急值"通报与接收各个环节存在的问题，提出针对性的改进策略。

选取2017年1月至2020年3月聊城市人员医院PDCA循环法对"危急值"执行过程中各个环节出现的问题进行针对性管理干预，统计管理前后的"危急值"通报率、记录合格率、随访成功率、诊断符合率，以χ²检验进行统计比较，分析PDCA针对性干预措施的效果。

PDCA法干预后通报率由80.0%提高至99.5%以上，差异均有统计学意义（χ²=35.446、0.010、0.148，P均<0.05）；随访成功率由98.7%提高至100%，差异有统计学意义（χ²=4.703，P<0.05）；记录合格率由89.3%提高至100%，差异有统计学意义（χ²=33.782，P<0.001）。诊断符合率有所提高，但差异无统计学意义（P>0.05）。

PDCA法及时干预可有效提升"危急值"通报率、记录合格率、随访成功率，保证医疗安全。

To analyze the problems existing in each link of critical value reporting system in ultrasound department, and on this basis, to propose the relevant strategies.

PDCA method was used to carry out targeted management intervention on the problems in each link of the implementation process of "critical value" report. The "critical value" report rate, record qualification rate, follow-up success rate, and diagnostic coincidence rate before and after management were compared by χ² test to analyze the effect of PDCA targeted intervention measures.

After PDCA intervention, the report rate increased from 80.0% to more than 99.5% (χ²=35.446、0.010、0.148, P<0.05); the follow-up success rate increased from 98.7% to 100% (χ²=4.703, P<0.05); the record qualification rate increased from 89.3% to 100% (χ²=33.782, P<0.001); the diagnostic coincidence rate was improved, but the difference was not statistically significant.

Timely PDCA intervention can effectively improve the "critical value" report rate, record qualification rate, and follow-up success rate to ensure medical safety.
