失败模式和效应分析在放疗流程QC中应用进展

随着放疗技术的迅速发展,传统质量管理将从以设备为重心的策略转移到以多人员参与的过程为重心。基于预测性风险评估的失效模式与风险分析方法,近年逐步被应用于放疗的流程质量管理。FMEA方法包含四个主要步骤,依次是流程树梳理、FMEA、差错树分析以及流程质量管理方案设计,具体的方法和结果因各放疗流程的特异性以及参与人员的主观性而有所差异,在其可靠性和可行性方面也进行了相关的验证和考虑。本文就FMEA方法在一些放疗中心开展的具体情况作简要综述。

Progress in application of failure mode and effect analysis in the quality control of radiotherapy process

With the rapid development of radiotherapy technology, traditional quality management will shift from a device-centric strategy to a process involving multiple people. In recent years,failure mode and effect analysis(FMEA)based on predictive risk assessment has gradually been applied in the quality management of radiotherapy process. The FMEA approach mainly includes four steps: process tree management,FMEA, error tree analysis, and the design of scheme for process quality management. The specific methods and results are different due to the specificity of radiotherapy process and the subjectivity of participants. Its reliability and feasibility have also been considered and verified. This article reviews the application of FMEA approach in some radiotherapy centers.
