With increasing deployment, complexity, and sophistication of equipment and related processes within the clinical imaging environment, system failures are more likely to occur. These failures may have varying effects on the patient, ranging from no harm to devastating harm. Failure mode and effect analysis (FMEA) is a tool that permits the proactive identification of possible failures in complex processes and provides a basis for continuous improvement. This overview of the basic principles and methodology of FMEA provides an explanation of how FMEA can be applied to clinical operations in a radiology department to reduce, predict, or prevent errors. The six sequential steps in the FMEA process are explained, and clinical magnetic resonance imaging services are used as an example for which FMEA is particularly applicable. A modified version of traditional FMEA called Healthcare Failure Mode and Effect Analysis, which was introduced by the U.S. Department of Veterans Affairs National Center for Patient Safety, is briefly reviewed. In conclusion, FMEA is an effective and reliable method to proactively examine complex processes in the radiology department. FMEA can be used to highlight the high-risk subprocesses and allows these to be targeted to minimize the future occurrence of failures, thus improving patient safety and streamlining the efficiency of the radiology department.
随着临床影像环境中设备和相关流程的不断部署、复杂化和精密化,系统故障更有可能发生。这些故障可能对患者造成不同的影响,从没有伤害到毁灭性的伤害。失效模式和影响分析(FMEA)是一种工具,可主动识别复杂流程中可能出现的故障,并为持续改进提供基础。本文概述了 FMEA 的基本原理和方法,解释了如何将 FMEA 应用于放射科的临床操作,以减少、预测或预防错误。解释了 FMEA 过程的六个连续步骤,并以临床磁共振成像服务为例,说明 FMEA 特别适用的情况。简要回顾了美国退伍军人事务部国家患者安全中心引入的称为医疗保健失效模式和影响分析的传统 FMEA 的修改版本。总之,FMEA 是一种主动检查放射科复杂流程的有效且可靠的方法。FMEA 可用于突出显示高风险子流程,并针对这些流程进行优化,以最大程度地减少未来故障的发生,从而提高患者安全性并简化放射科的效率。
