Objective　To explore the influence of digital information management mode on the time cost and reliability

of sterilized items management in operating rooms. Methods　The present study was performed basing on the sterilized items

from the operating division, Department of Plastic and Reconstructive Surgery. A total of 1 790 sterilized instrument kits were

collected from December 2021 to January 2022. According to the management, the kits were divided into two groups. The experimental group (n=910) adopted the digital information management mode, while the control group (n=880) adopted the conventional ledger management mode. The item-registering time, the validity-checking time, the storage cabinet settling time and

the item-taking time were recorded in both groups. A group t test was applied to evaluate the difference between the two groups.

Meanwhile, the reliability of the two groups, including sterilized item expiration, loss, and mistaking delivery, were also recorded

and analyzed with Chi-square test. The satisfaction ratio of the medical staff was evaluated at the same time. Results　Of the

experimental group, the validity-checking time, the storage cabinet settling time and the item-taking time were significantly less

than those of the control group (P<0.001). The item-registering time of the experimental group was significantly longer than that

of the control group, but the total management time was still better than that of the control group (P<0.001). The item expiration

rate, the item loss rate and the mistaking delivery rate of the experimental group were all lower than those of the control group
