[Application of failure mode and effect analysis in reducing the risk of nosocomial infection]

Objective: To explore the effect of failure mode and effect analysis (FMEA) in the management of nosocomial infection, and provide reference for the effective prevention and control of nosocomial infection. Methods: Using FMEA to identify, analyze, evaluate and screen out the high-risk events of nosocomial infection in January 2020, from which two hospital level priority improvement projects of hand hygiene compliance and blood-borne occupational exposure were determined. After risk control and intervention measures, the effects before and after improvement were compared. Results: Except for the lack of incentive mechanism and insufficient communication between medical and nursing teams, the differences in hand hygiene compliance and blood-borne occupational exposure risk priority coefficients before and after the implementation of FMEA were statistically significant (P<0.05) . After the implementation of FMEA, the hand hygiene compliance was 74.92% (79375/105953) , which was significantly higher than 68.40% (58361/85328) before the implementation of FMEA, and the difference was statistically significant (χ(2)=996.55, P<0.01) . The incidence of blood-borne occupational exposure after the implementation of FMEA was 3.85% (80/2080) , which was lower than the 6.16% (123/1998) before the implementation of FMEA, and the difference was statistically significant (χ(2)=11.49, P<0.01) . Conclusion: FMEA has a good effect in nosocomial infection management. It can identify and evaluate the risk of nosocomial infection prospectively, so as to control the risk effectively.
