Objective

2

The present study investigates the application and effectiveness of an automated guided vehicle (AGV) and a sterilization monitoring report in the disinfection and sterilization process.

Methods

2

The AGV is applied for auto loading and unloading in the disinfection and sterilization process and for route planning. A reusable instrument transportation management mode and AGV instruction system are constructed. Following the requirements of the

Central sterile supply department (CSSD) - Part 3: Surveillance standard for cleaning

disinfection and sterilization

(WS 310.3—2016) for recording critical factors affecting the sterilization process and results

this study used the information tracking system in the central sterile supply department (CSSD) to automatically capture all critical points in time

temperature

and temperature from the equipment monitoring system. In addition

the actual value and the reference value items in the process flow sheet were set up using the clinical chemical examination report template to automatically determine whether the parameters comply with the requirements; parameter abnormalities are displayed with red arrows. The results of chemical and biological monitoring of sterilized items were recorded using a scanner to form a sterilization monitoring report.

Results

2

In comparison between before and after the application of AGV

the daily manual transportation and time consuming were reduced from an average of 5 minutes to an average of 1 minute

with a statistically significant difference (

P

<

0.01). In comparison between the sterilization monitoring report before and after the application

the recording time of parameters and monitoring identification was reduced from an average of 3.5 minutes to an average of 1 minute

with a statistically significant difference (

P

<

0.01). A satisfaction survey was conducted from the dimensions of environment

occupational exposure

simplicity of operation

physi

cal exertion

time consuming

and pleasure. The satisfaction rate increased from 75% to 98.4%.

Conclusion

2

AGV is an intelligent logistics system that replaces repetitive and unitary manual labor and significantly improves the work efficiency of sterilization operators. It is closely connected with the Internet of Things (IOT)

intelligent devices

and information tracking system to realize the intelligent construction of CSSD by reducing occupational injuries such as lowering physical exertion and simplifying operations

and to improve the satisfaction of sterilization operators. The combined application of sterilization monitoring report can not only improve the work efficiency

but also reduce the misidentification of the process flow sheet to reduce the occurrence of adverse events and improve the quality of work.
