Study On Risk Control Of Hospital Space Environment Based On Medical Safety

This dissertation aims to provide theoretical and practical basis for healthcare safety risk management through getting the architecture space environment factors.Healthcare safety is a serious public health topic,which is related to the rights of life and social stability.Frequent adverse events show that the level of healthcare safety has not met people's need in China.Healthcare safety risk management is a systematic engineering.As the platform of medical activities,healthcare architecture is an important subsystem.The safety connotation of healthcare architecture is not only the building noumenon,but also to ensure the safety of medical treatment.Since architecture plays an essential role in safety system,we must try to solve the related problems from the view of architecture,in order to promote the social development and individual freedom.Based on the medical experience feedback and survey data,and take system theory and safety science as theoretical guide,this study sets up a connection between healthcare safety and space environment factors.It also improves the safety viewpoint of healthcare architecture,trying to promote positive effect and reduce negative impact of space environment factors on medical activities.Selecting important healthcare safety issues which also have close relation to space environment is the prerequisite of getting useful applied conclusion through further research.Therefore,this study chooses four safety problems as the central issues through a series of investigations,and the results are medical errors,healthcare acquired infections,patient falls and occupational exposure.After that,this paper did a deep research to these four issues one by one with a same six-steps research process,which could be summed up as “analysis about the essence of the problem – analysis of the mechanism between space environment and healthcare safety – extraction of risk factors – analysis of the risk level of these factors – risk management model –risk management strategies”.Firstly,this study clarifies the the mechanism between the space environment and medical safety which is the basis of risk management.Secondly,it extracts the space environment risk factors through three methods which are data retrieval,live observation and experts interview.Thirdly,this study analyzed the risk level of the extracted factors which is determined by risk severity and frequency using expert questionnaire.Based on these research data,this study constructs a risk management model for each safety issues.Taking the risk management model,risk level and the degree of controllability together as guidance,this study establishes the control points and summarizes the control strategies to each safety issue.(1)Design strategies for medical error control can be summarized as follows:improvement of space efficiency,control of confusion degree,creating a working environment to reduce staff fatigue and enhancing the sense of safety of patients.(2)Design strategies for healthcare acquired infection control can be summarized as follows:improvement of the microbial environment,reducing patient transfers and contact behaviors.(3)Design strategies for patient fall control can be summarized as follows:improving the functional layout to minimize the unnecessary movement of patients,providing the support for patients during moving process and creating a positive nursing care environment.(4)Design strategies for occupational exposure control can be summarized as follows:reduce exposure source through space environment,minimize harm scope through architecture layout,cont rol medical behavior through operational environment and set architectural technical barriers for specific invasion type.
