Application of Failure Mode and Effect Analysis in Perioperative Safety Check of Surgical Patients

Abstract

Objective: To evaluate the application effect of Failure Mode and Effect Analysis (FMEA) in perioperative safety check of surgical patients. Methods: Based on FMEA, 540 surgical patients from January to June 2020 were selected as the control group, and 540 surgical patients from January to June 2021 were served as the observation group. By analyzing the failure modes of the perioperative safety verification process of surgical patients, 13 failure modes were identified as the key points for improvement and corrective measures were developed. The Risk Priority Number (RPN) before and after failure mode and effect analysis was compared, as well as the accuracy rate of surgical safety verification and surgical identification, and the effectiveness of rectification was evaluated. Results: The mean RPN value before and after FMEA management decreased from 184 to 48.5; the accuracy of surgical safety check increased from 95.45% to 99.42% with a statistical difference (P < 0.01); the correct rate of surgical identification increased from 98.84% to 99.90%, but no statistical difference was observed (P ˃ 0.05). Conclusion: As used for perioperative safety verification of surgical patients, FMEA is very helpful in identifying potential defects in process improvement, significantly reduces the risk priority index and increases the accuracy of surgical safety check.
