PDCA在降低下颌阻生第三磨牙拔除术干槽症发生率的应用

Application of PDCA Circle in Reducing the Incidence of Dry Socket following the Extraction of Mandibular Impacted Third Molars

目的:探讨PDCA循环法降低下颌阻生第三磨牙拔除术干槽症发生率的应用效果。方法:应用PDCA循环法收集资料、发现问题、分析原因、制定计划、组织实施,进行效果评价。将实施PDCA管理前、后各6个月的拔除下颌阻生第三磨牙的病例分别设为对照组和改进组,对照组584例,改进组602例,统计各组干槽症发生率,然后进行比较。结果:实施PDCA循环管理前、后的干槽症发生率分别为9.6%和4.4%,两组间存在显著差别(P<0.01)。结论:PDCA循环法在降低下颌第三磨牙拔除术干槽症发生率方面具有明显效果,能有效提高医疗质量。

Objective：To explore the application effects of PDCA circle method in reducing the incidence of dry socket following the extraction of mandibular impacted third molars.Methods：We collected material,found problem,analyzed the reason,set plan,organized and implemented the plan,and evaluated the effects using PDCA circulation method.1186 mandibular impacted third molars were divided into improvement group（n=602）and control group（n=584）.The incidences of dry socket within two groups were compared.Results：The incidence of dry socket in the improvement group was 4.4%,and that in the control group was 9.6%.There was significant difference between two groups（P〈0.01）.Conclusion：The PDCA circulation method is effective in reducing the incidence of dry socket following removal of mandibular impacted wisdom teeth,which is an effective way to improve the quality of medical treatment.
