通过应用PDCA循环管理工具，改善病房检验危急值使用的有效性和及时性。

成立PDCA循环小组，通过调查现状、发现问题、分析问题、拟定计划、解决问题，不断的分析总结和改进，制定出新的危急值管理制度，并继续监督临床科室执行危急值的情况。

执行PDCA循环管理后，检验危急值通报率由95.67%上升至100%，护士危急值接收率由70.56%上升至98.81%，差异有统计学意义(χ²=14.85、98.81，P<0.01)。

通过PDCA管理，住院患者的检验危急值通报率和接收率明显提升，能更好的执行18项核心制度中的危急值制度，从而保证了患者的安全。

To improve the effectiveness and timeliness of ward inspection for critical value by applying PDCA cycle management tools.

A PDCA cycle group was established to investigate the status quo, find and analyze problems, draw up plans, solve problems, continuously analyze, summarize and improve, develop a new critical value management system, and continue to supervise the implementation of critical values in clinical departments.

After the implementation of PDCA cycle management, the critical notification rate increased from 95.67% to 100%, and the nurse critical value acceptance rate increased from 70.56% to 98.81%, (χ²=14.85、98.81, P<0.01).

Through PDCA management, the hospitalized patients′ critical value notification rate and acceptance rate have been significantly improved, which can better implement the critical value system of the 18 core systems, thus ensuring patients′ safety.
