Application of failure mode and effect analysis in management of precision instrument in operating room of ophthalmology department

Objective To explore the application of failure mode and effect analysis in management of precision instrument in operating room of ophthalmology department. Methods We designed the handover process between operating room of ophthalmology department and supply room, the process of using precision instrument, the workflow of instrument management in nurses. And then, we assessed and analyzed the potential failure mode in the management of precision instrument with the method of failure mode and effect analysis. Besides, failure mode was also evaluated and improved. Results There were failure modes with high risk in the management of precision instrument including that the handover process between operating room of ophthalmology department and supply room was not precise enough (risk priority number, RPN=448) ; the staff of handover process was not fixed (RPN=360) ; there was no full-time cleaning staff in supply room (RPN=288) ; use registers in nurses and the check in precision instrument were all in a lack of standardization (RPN=210, 180) and so on. After adopting targeted corrective actions, the corresponding scores of RPN fell to 0, 0, 40, 70, 90. Conclusions The application of failure mode and effect analysis in management of precision instrument in operating room of ophthalmology department has good effects with no related adverse event on precision instrument.
