Abstract:

Objective To evaluate the centralized endoscopy management at the disinfection supply center based on an intelligent traceable information system. Methods From January 2021 to June 2022, 252 colonoscopes were selected after routine colonoscopy at the endoscopy center, and 126 colonoscopes were assigned to the observation group and 126 to the control group. The intelligent traceable information system was used for information input and access in the process of disinfection, washing, recycling and access. The control group administered decentralized management from the endoscopy center, while the observation group administered centralized management from the disinfection supply center. Adenosine triphosphate (ATP) biofluorescence detection method was used to compare the relative light unit values of the surface, the valve and the cavity of endoscopes of the two groups. The positive rate of microbe culture on the surface, the cavity, the biopsy mouth, the air injection mouth and the suction mouth were compared between the two groups. The contents of aerosol particles in endoscope cleaning environment were compared between the two groups. Staff satisfaction with recycling and usage were compared. The labor cost, operating cost and endoscope maintenance rate of centralized management and decentralized management were compared. Results The qualified rates of valve and cavity cleaning in the observation group [94.4% (119/126), 93.7% (118/126)] were higher than those in the control group [90.5% (114/126), 88.9% (112/126); χ2=5.686, χ2=8.841, P<0.05]. The positive rates of microbial colony growth in the endoscopic cavity, biopsy mouth, air injection mouth and negative pressure suction mouth in the observation group [19.0% (24/126), 17.5% (22/126), 1.6% (2/126), 12.7% (16/126)] were lower than those in the control group [30.2% (38/126), 24.6% (31/126), 4.8% (6/126), 19.8% (25/126); χ2=12.215, χ2=9.003, χ2=6.446, χ2=9.106, P<0.05]. The 0.5 μm and 2.5 μm aerosol particles produced by air in the observation group (40 706 874 ±12 563 749 /m3, 226 530±87 632 /m3) were lower than those in the control group (46 892 654±13 209 872 /m3, 263 281±45 219 /m3; t=8.223, t=4.265, P<0.05). The labor cost and the operating cost of the observation group were 63 128.45 yuan and 56 320.13 yuan respectively, which were lower than 208 258.25 yuan and 208 415.22 yuan in the control group. The satisfaction with recycling and usage in the observation group [96.1% (98/102), 97.1% (100/103)] was higher than that in the control group [78.4% (80/102), 82.5% (85/103); χ2=13.211, χ2=15.223, P<0.05]. There was no endoscopic maintenance in the observation group, and 2 cases of endoscopic maintenance in the control group. Conclusion The centralized endoscopy management based on the intelligent traceable information system can improve the level of endoscopy cleaning, disinfection, and storage, reduce labor and operating costs, improve work efficiency and satisfaction with disinfection supply centers and endoscopy departments, and reduce the risk of iatrogenic infection of endoscopes.
