【摘要】：目的探讨失效模式和效应分析(failure mode and effect analysis,FMEA)在改进MRI检查执行流程中提高预约执行准时率的效果。方法组建FMEA项目研究团队,运用FMEA对成都大学附属医院MRI检查执行流程中的失效环节进行风险分析,根据其严重程度(severity,S),发生频度(frequency of occurrence,O),可探测度(liklihood of detection,D),计算各环节风险优先数(risk priority number,RPN),对高风险环节进行流程再造,制定标准操作流程,观察预约执行准时率及医、患满意度改善情况。结果MRI预约检查执行准时率由改进前的50.00%上升到改进后的86.55%,患者满意度由原来的62.40%上升到87.28%,医护人员的满意度由原来的77.77%上升到87.78%,P均0.05,有统计学意义。结论运用FMEA对住院患者MRI检查流程进行失效环节改进,有效改善了MRI的运行效率。
[Abstract]:Objective to investigate the effect of failure mode and effect analysis (failure mode and effect analysis,FMEA) on improving the timing of reservation execution in the improvement of MRI inspection execution process. Methods the FMEA project research team was set up and FMEA was used to analyze the risk of failure in the process of MRI inspection and execution in Chengdu University affiliated Hospital. According to the severity (severity,S) and the frequency of (frequency of occurrence,O, the risk analysis was carried out in Chengdu University affiliated Hospital. (liklihood of detection,D), calculate the risk priority of each link (risk priority number,RPN), re-engineering the process of high-risk links, formulate the standard operating process, observe the improvement of appointment execution timing, doctor, and patient satisfaction. Results the time-on-time rate of MRI reservation examination increased from 50.00% before improvement to 86.55% after improvement, and the patient satisfaction increased from 62.40% to 87.28%. The satisfaction rate of medical staff increased from 77.77% to 87.78% (P < 0.05). Conclusion FMEA was used to improve the failure process of inpatients with MRI, which effectively improved the operation efficiency of MRI.
