To analyze the impact of the improved defect management mode applied by the disinfection and supply center on the occurrence of wet packets after pressure steam sterilization.

A retrospective analysis was performed on the sterilization conditions of 155,272 sterilization kits performed by pressure steam sterilization in the Wuxi No.2 Chinese Medicine Hospital sterilization supply center from January 2024 to December 2024. The sterilization conditions were divided into control group (from January 2024 to June 2024, n=77636) and observation group (from July 2024 to December 2024) before and after the implementation of the defect management improvement mode. n=77636), the control group implemented the conventional management mode, and the observation group implemented the defect management improvement mode. The pass rate of each process of pressure steam sterilization, the quality of wet packet management and the occurrence of wet packet were compared between the two groups.

The pass rate of pressure steam sterilization processes such as packaging, loading, sterilization and unloading in the observation group was higher than that in the control group, and the difference was statistically significant (P<0.05). The scores and total scores of the four dimensions of exterminator packaging, loading and unloading management, sterilization management and wet bag record management in the observation group were higher than those in the control group, with statistical significance (P<0.05). The incidence of wet bag in observation group was lower than that in control group, and the difference was statistically significant (P<0.05).

The application of defect management improvement mode in central sterile supply department can improve the qualified rate of pressure steam sterilization and the quality of wet package management, so as to effectively reduce the occurrence of wet package.
