Design And Implementation Of Medical Master Data Quality Evaluation System

Medical master data is important data information for various medical institutions such as hospitals and imaging centers.In recent years,China has actively promoted the digitization of medical treatment.While achieving remote diagnosis and sharing between data centers,data quality problems have also followed.Aiming at the quality of medical master data,this paper proposes designs and implements a system for quality evaluation of medical master data.It aggregates master data from a variety of external medical systems and evaluates the quality of the master data based on the evaluation rules and the CRITIC-G1 weight calculation method to obtain high-quality master data,realize inter-hospital data sharing,break the data island,and help hospitals operate efficiently.The multi-dimensional data quality comprehensive evaluation method studied in this paper is compared with the evaluation method that completely relies on expert weight assignment in traditional medical data quality evaluation.When calculating the weight of each evaluation standard,a weight analysis method combining subjective and objective is used.It avoids the problem of ignoring the relationship between data due to subjective experience caused by the expert assignment method in traditional medical data quality assessment.It also avoids the unreasonable weighting caused by the use of objective data analysis and the lack of subjective decision-making experience guidance,which is beneficial to Data for a more scientific and comprehensive quality assessment.This paper starts with data quality issues,and introduces the development and current status of data quality assessment at home and abroad.Then it introduces the background knowledge and related technologies required in the design and implementation of the system.Then it describes the system requirements detailed analysis.Then the overall design of the system was made,the functional structure and key processes of the system was clarified,the system was divided and designed in detail,the key issues of the medical master data quality evaluation system were introduced,and solutions were proposed.After that,according to the requirements and design and implementation of each module of the system.Finally,a comprehensive test of the system,the test results meet the expected needs.
