Objective:To investigate the role of a continuously developed information traceability system in the management of foreign medical instrument packages in central sterile supply department (CSSD).Methods:A total of 350 foreign medical instrument packages processed by CSSD during May to June 2021 in Shenzhen Hospital, University of Chinese Academy of Sciences were included in the control group. These packages were managed with the original information traceability system. A total of 375 foreign medical instrument packages processed by CSSD during July to August 2021 in Shenzhen Hospital, University of Chinese Academy of Sciences were included in the observation group. These packages were managed with a continuously developed information traceability system. Step-by-step reminding and early warning control were performed according to the problems encountered in actual operation. Quality management indexes of foreign medical instrument packages and the incidence of adverse events were compared between the two groups.Results:The percentages of good cleaning and functional integrity of the foreign medical instrument packages, functional integrity of sterile barrier after sterilization, timely monitoring of biological culture results, standardized handover, postoperative cleaning and detoxification in the observation group were 96.0% (360/375), 98.7% (370/375), 99.5% (373/375), 98.9% (371/375), and 99.7% (374/375), which were significantly higher than those in the control group [84.2% (295/350), 92.6% (325/350), 91.4% (320/350), 89.1% (312/350), 84.9% (297/350), χ2 = 28.48, 15.40, 27.72, 31.80, 58.12, all P < 0.05]. The percentages of instrument breaking, instrument mixed or damaged, wet packages, information label error, oversized and overweighed packages in the observation group were 0.8% (3/375), 0.3% (1/375), 0.8% (3/375), 0.3% (1/375), and 0.5% (2/375), respectively, which were significantly lower than those in the control group [4.3% (15/350), 4.6% (16/350), 3.4% (12/350), 10.0% (35/350), 7.7% (27/350), χ2 = 9.08, 14.65, 6.17, 36.34, 24.31, all P < 0.05]. Conclusion:A continuously developed information traceability system is very important for management of medical instrument processed in CSSD. A developmental traceability system not only continuously improves quality control of foreign medical instrument and decreases the incidence of adverse events, but also increases the responsibility and enthusiasm of staff, thereby ensuring the safety for patients.
