Abstract

Abstract:

Objective

To analyze the effect of PDCA cycle in improving the biosafety management of pathogenic microorganisms in hospitals.

Methods

The pre-implementation control group from April 2018 to March 2019 and the research group after the implementation of the PDCA cycle from April 2019 to March 2021 were compared the correct treatment rate of safety accidents, laboratory disinfection, medical waste, and the infectious disease-positive specimens before and after implementation.

Results

Through PDCA cycle management, compared with the control group, the correct treatment rate of safety accidents in the research group increased by 14.30%, the correct treatment rate of laboratory disinfection increased by 17.40%, the correct treatment rate of medical waste increased by 10.56%, and the correct treatment rate of infectious disease positive specimens increased by 12.48%, and the difference was statistically significant (P＜0.05).

Conclusions

In view of the problems that are easy to occur in the laboratory, the rational use of PDCA cycle management according to the actual situation of the laboratory can reduce laboratory safety problems such as irregular laboratory disinfection, improve laboratory safety quality, and have high application value.

Key words: PDCA cycle, Pathogenic microorganism laboratory, Biosafety, Laboratory management
