应用失效模式与效应分析降低微创手术患者安全风险的研究

目的：降低微创手术患者的安全风险，从而减少手术失误，提高手术的安全性。方法：选取2010年1—12月本院微创手术患者为对照组，进行安全风险研究，对微创手术患者进行查对流程的监测，经统计讨论分析，计算事先风险指数（RPN），RPN值高的6个项目是影响手术患者安全的高危因素，选取2011年1—12月本院微创手术患者为实验组，运用失效模式与效应分析（FMEA）高危因素，分析高危环节产生的原因，并提出防范对策。结果：对照组6项高危因素事先风险指数总和1570，均值261．67；实验组6项高危因素事先风险指数总和385，均值64．67，实验组高危因素事先风险指数低于对照组。结论：通过对内镜微创手术患者安全风险进行研究，找出安全风险高的环节，进行失效模式与效应分析，可降低高危因素事先风险指数，有效保障手术安全，降低手术风险，提高手术质量。

The Study of Using Failure Mode and Effects Analysis to Improve Patient Safety in Minimally Invasive Surgery

Objective：To lower the safety risk of minimally invasive surgery patient, thus to prevent operation error and improve operation safety. Method：Risk Priority Number（RPN） was used to measure and analysis patients of 2010 and 6 risk factors with high risk priority score were identified. By applying FMEA, countermeasure were taken form January of 2011 as the control group to correct them.Result：The six RPN was 1570 and 385 respectively in test group and control group and had significant difference.Conclusion：Applying FMEA to find out and study the risk factor are key to reduce RPN, protect operation safety , prevent operation error and improve operation quality.
