This study was conducted at a tertiary hospital,where the PDCA(Plan-Do-Check-Act)cycle was applied to establish a refined electricity conservation management system encompassing organizational structure,institutional frameworks,technical measures,and awareness campaigns.Through data analysis,on-site investigations,and case validation,multidimen-sional initiatives were implemented,including enhancing institutional frameworks,carrying out energy-saving technological up-grades,leveraging information technology,adopting market-based electricity procurement,and conducting publicity and educa-tion.The results demonstrated that after the implementation of the system,the hospital's annual electricity consumption growth rate showed a year-on-year decline,reaching 2.25％in 2024-a reduction of 3.66 percentage points compared to 2022.This study verifies the scientific rationale and practical effectiveness of the PDCA cycle in electricity conservation management,offering rep-licable experience for healthcare institutions striving to achieve energy savings and carbon emission reduction goals.

Objective To evaluate the effectiveness of a hospital logistics operation and management based on the"one center,four platforms"model.Methods In line with the grading evaluation standards for hospital intelligent management,we used technologies such as big data,Internet of Things,Internet Plus,and artificial intelligence to develop a"one center,four platforms"model.This model consisted of a logistics intelligent operation and maintenance management center,an equipment control information platform,a security prevention information platform,an energy consumption monitoring information platform,and an operation management information platform.Results The equipment fault resolution capability,enhanced by the"smart linkage",showed a significant improvement.In 2022,false alarms decreased by 28.63%compared to 2021,with high-level and ordinary-level alarms decreasing by 69.53%and 33.15%,respectively.The"one-stop"logistics service capability was signifi-cantly improved,as indicated by a 2.92%decrease in maintenance frequency in 2022 compared to 2021.This improvement was further reflected in the quality of maintenance and a decrease in the repeated maintenance occurrences.The energy consumption control capability,based on the"data mining",showed a significant improvement,with an 8.71%year-on-year decrease in en-ergy expenditure of ten thousand yuan in 2022 compared to 2021.Conclusion The"one center,four platforms"model can sig-nificantly enhance the efficiency of logistics operation and maintenance management.
