Abstract:
Objective:To analyze the design and application of a three-tier architecture medical consumables management information system based on IoT technology.Methods:Utilizing IoT technologies including network communication,radio frequency identification(RFID),and intelligent processing,a three-tier architecture system comprising perception,application,and interaction layers was designed to achieve comprehensive management of medical consumables throughout their lifecycle.A total of 520 clinical medical consumables in use at West China Hospital of Sichuan University from January 2022 to January 2023 were selected.Using a random number table,they were divided into an observation group and a control group,each containing 260 items.The control group employed conventional management practices,while the observation group utilized the IoT-based three-tier architecture medical consumables management information system.The study compared the quality of medical consumables management,time spent on consumables verification,inventory backlog,test results in different scenarios,and the time required to manage medical consumables per single treatment session between the two management models.Results:The observation group scored(95.69±10.66)points for the timeliness of medical consumables delivery,(94.14±11.33)points for management standardization,and(94.36±11.54)points for the timeliness of consumables recovery.was(94.36±11.54).All scores were significantly higher than those in the control group,with statistically significant differences(t=11.067,9.048,9.492,P<0.05).The observation group exhibited shorter monthly and quarterly physical inventory reconciliation times,as well as lower monthly and quarterly inventory backlogs compared to the control group,with all differences statistically significant(t=19.303,21.303,13.114,28.734,P<0.05).The observation group demonstrated significantly shorter average response times and average processing times for daily replenishment of medical supplies compared to the control group,while exhibiting significantly higher average inventory accuracy rates.All differences were statistically significant(t=11.614,22.122,12.103,P<0.05).During high-demand periods,the observation group exhibited significantly shorter average response times and average processing times compared to the control group,while inventory accuracy was significantly higher.All differences were statistically significant(t=8.358,11.051,22.157,P<0.05).The observation group also demonstrated shorter preparation times for medical supplies,response times for ad hoc requests,and return times to inventory compared to the control group,with statistically significant differences(t=15.881,19.334,17.102,P<0.05).Conclusion:Implementing a three-tier architecture medical consumables management information system based on IoT technology significantly enhances the quality of medical consumables management.It reduces consumables verification time and inventory backlog,enables rapid response and processing during routine replenishment and high-demand periods,and markedly decreases the time required for managing medical consumables per patient visit.
