An Emperical Investigation Of Electronic Medical Records System Usage Behavior And Its Impact On Performance

Hospital information system is the emerging hotspot in domesticmodernization of hospitals, which is also the main content of the nation’s healthinformatization. It is clearly pointed out in the12th Five-Year Plan of HealthInformatization Construction that electronic medical records system is the coreof the construction of hospital information, the base of construction of theregional medical platform, which is significant to the he nation’s healthinformatization construction. The digitization of hospital relys on modernmedical and information technology to improve the quality of medical services,management level and the efficiency of operations. In2011, the Ministry ofHealth has developed the basic specifications for electronic medical records, andcarried out the experimental work in110hospitals across the country. Meanwhile,the phenomenon IT Productivity Paradox appeared, which some hospitals’investment in IT did not enhance the performance, however, made them in therough mud. Western researchers posed the “Time delay hypothesis”,Substitution Effect hypothesis to try to open the black box between the ITinvestment and performance. They brought the affluent theory to explain theevaluation of information system performance. However, the evaluation indexand function mechanism had lots of disputes, and how IT technology enhancesthe enterprises’ performance lacks the theoretical framework. So, it is analyzedthat the factors affecting the use of electronic medical records from thisperspective, designing to improve the effect of the use of electronic medicalrecords system and the level of performance management, ultimately improve thecore competitiveness of the hospital. The main content of the paper is asfollows：Explain the mechanism of the information system using behavior to theperformance effect. From the theory of information technology acceptance,information system success theory as the core， summarizing the theory ofreasoned action abroad, planned behavior, and innovation diffusion, integratingthe technical task of matching theory, it analyzes the model of the impact of the electronic medical record system using behavior on performance, proposesrelated research hypothesis, and explores the main affecting factors from thetechnical features of the system, to seek an effective way to improve workingefficiency, which are the important support of the thesis.Construct structural modular mode of hospital information system usingbehavior to the performance effect. It constructs structural equation model of theimpact of the system using behavior on performance by index designing forfactors of technology service, users and the using behavioral. It verifies thehypothesis model by data analysis of measurement reliability, convergent anddiscriminant validity. By comparing the impacts on the performance, it doesempirical analysis on the significant differences of the performance, and studiesthe influencing factors and path.Construct regress mode of electronic medical records using satisfaction tothe performance effect. Through using the empirical research methods ofmultiple regression analysis and SPSS.15, it constructs three regression modelswith outpatients’ amount, consultation income and medical record quality asperformance indicator, to analyze how the satisfaction factors affect theperformance when doctors use electronic medical records. Gender, age, academicqualifications and departments of doctors as control variables, it explores thesignificant difference of the effect on doctors’ performance, and test therelationship between satisfaction and performance of electronic medical records.Pose the new perspective and methods of researching information systemusing performance. Through the research of electronic medical recordsinfluencing factors, the paper analyzes the impact on performance with newperspective and method, improves the system of management information, andmaximizes effectiveness of information system in hospital. This study strives tomake a breakthrough, both in theory and in practice, to provide guidance andreference for the successful implementation of health information technology inChina.Theoretically, the current research on the hospital information system homeand abroad fails to address the doctor’s level. Based on behavioral theory, theempirical comparative analysis on influencing factors model of different age,gender and department doctors, helps to expand the scope of the research on performance theory of information systems. At the same time, based on thesignificance and difference test to the medical questionnaire and hospitalexperience data, an effective solution is found to improve the traditional metrics,thus providing a new method and a new perspective for the information systemperformance metrics. From a practical perspective, on the one hand, this studyhelps to identify the problems in the performance management of the hospitalinformation system, so that hospitals can improve performance managementprograms and management systems to improve hospital core competitiveness; onthe other hand, a wealth of information system performance evaluation theoriesis liable to strengthen the enterprise strategic management, and therefore,conducive to maximize the value of IT investments, and lay a solid theoreticalfoundation for the successful implementation of health information technology inChina.
