Application Research Of Data Visualization Technology In Performance Audit Of H Public Hospitals

In the context of big data era,the explosive growth of data has brought enormous challenges to the construction of government audit information.It is the great theoretical significance and application value to study how to use the big data technology to give full play to audit supervision.Due to the imperfect construction of information platforms at all levels and the uneven development level,the performance audit data is scattered.Even if some data models are built,it is difficult to promote them.In the end,the hidden information in the data cannot be mined.From the literature review at domestic and abroad,some traditional electronic data auditing tools can help analyze audit data and meet the basic needs of electronic data auditing.However,it is lack of research how to see the essence through the phenomenon and analyze the deeper problems through the audit trails found.This dissertation first summarizes the basic concepts of public hospital performance auditing and the uniqueness of public hospital performance auditing,and then puts forward the analysis needs of data visualization technology in public hospital performance auditing.Secondly,it comprehensively explains the characteristics of data visualization,system framework and analysis process.Boldly predict the effective use of data visualization technology in different audit stages,since drug addition is the key content of the compensation mechanism in the performance audit of public hospitals,taking the H public hospital drug addition audit as an example,using data visualization technology to analyze whether the hospital exists drug add-on situation,and it is also in-depth to explore whether the hospital has increased the rate of drug mark-ups in a disguised manner,such as drug additions.This case study further verifies the good results achieved by data visualization technology in public hospital performance audits.Suggested problems in the performance audit of public hospitals under the big data environment.In summary,this dissertation uses the case study method as an argument to verify the validity of data visualization analysis,discusses the advantages,disadvantages and application of the method,and explores the importance of data visualization technology in theperformance audit of public hospitals.Function,visually model the data of the public hospital's trial and present data visualization results such as graphics and images,allowing auditors to visually perceive and analyze visual results,and mine more implicit information to obtain effective audit evidence and prevent auditing risk.The research results provide theoretical basis and technical methods for electronic data auditing by audited entities in the future.
