Failure mode and effects analysis (FMEA) to enhance the safety and efficiency of Gamma Knife radiosurgery.

ABSTRACT: This risk analysis describes our Failure Mode and Effects Analysis (FMEA) for Gamma Knife stereotactic radiosurgery at our community hospital. During bi-monthly meetings over 5 months, our FMEA team mapped a detailed Gamma Knife process tree and identified potential failure modes, each were scored a Risk Priority Number (RPN) for severity, occurrence, detectability. In our process tree of 14 subprocesses and 177 steps, we identified 31 potential failure modes: 7 high scoring (RPN o150) and 3 modes (<150) selected by clinicians for mitigation strategies. Eighteen months later, rescoring of high-risk failure modes showed significant reduction in RPN scores, thus confirming the benefit of our FMEA mitigation strategies. Our study provides a roadmap to achieve high-quality Gamma Knife radiosur
