PDCA plays a very important role in the hygienic management of hospital operating rooms. Before the PDCA management from February 2018 to February 2019, routine hygiene management in the operating room was adopted; after the PDCA management from February 2018 to February 2019, PDCA cycle management was adopted. 500 surgical patients were randomly selected from both groups. We compare the quality control checklist scores of hand hygiene management, environmental hygiene management, medical waste management, and disinfection and isolation management in the routine group and the PDCA group. We also compared the detection rate of pathogenic bacteria in surgical incisions of the routine group and the PDCA group and the infection rate of various surgical incisions, air samples, surface samples, disinfectants, and sterilization rates of sterile items. The PDCA group’s hand hygiene management score, environmental hygiene management score, medical waste management score, and disinfection and isolation management score were higher than those in the conventional group ( P 0.05 ). The detection rate of pathogenic bacteria in the PDCA group, the infection rate of type I, type II, and type III incisions, and the total infection rate of surgical incisions were lower than those in the conventional group, and the difference was statistically significant ( P 0.05 ). The qualified rate of air samples and surface samples in the PDCA group was higher than that in the conventional group ( P 0.05 ), and the difference in the qualified rate of disinfectants and sterile items between the two groups was not statistically significant ( P > 0.05 ). The hygiene management of the operating room adopts PDCA sustainable improvement management measures to effectively increase the qualification rate of disinfection and sterilization, reduce the detection rate of pathogenic bacteria and infection rate of surgical incisions, and strengthen the management quality of hand hygiene, environmental hygiene, medical waste, and disinfection and isolation.
