Analysis Of Factors Influencing The Effective Use Of Electronic Medical Record System

Background:Electronic medical records is the core of the informatization construction of medical institutions.Promoting the informatization construction of medical institutions with electronic medical records as the core is of great significance to improving the efficiency of medical services and promoting the development of"smart hospitals".The electronic medical record system has a broad application prospect,and whether this potential can be fully utilized depends to a large extent on the actual use of the system users.As a direct user of the electronic medical record system,whether doctors can effectively use the electronic medical record system in their daily work directly affects the realization of personal goals and organizational goals.Therefore,this paper analyzes the factors that influence the effective use of electronic medical record system from the perspective of doctors.From the perspective of matching theory and task technology matching model,exploring how individual characteristics,task characteristics,and technical characteristics affect the effective use of the electronic medical record system is the focus of this paper.The research objectives,methods,results and conclusions are as follows:Objective:Based on the continuous application of electronic medical record systems in China’s medical industry,combining the matching theory and task technology matching model to construct a model of influencing factors for the effective use of the electronic medical record system.It provides some reference for exploring new fields of medical information technology research in China and designing a system that better matches the daily work of doctors.Methods:The research mainly adopts the interview method and questionnaire survey method,taking four tertiary Chinese medicine hospitals(integrated Chinese and Western medicine hospitals)in Nanjing as investigation object.Through interviews with the head of the information department and clinicians to understand the informatization construction of the four hospitals,the level of application of the electronic medical record system,and the specific factors that doctors pay attention to in the actual use of the electronic medical record system.The questionnaires were distributed on-site to analysis the factors affecting doctors’ effective use of the electronic medical record system,a total of 280 questionnaires,recycling 236,eliminate invalid questionnaires were 221,effective questionnaire recovery rate was 93.64%.Use statistical analysis software such as SPSS22.0 and SmartPLS3.0 to perform descriptive statistical analysis,reliability analysis,validity analysis,confirmatory factor analysis,and structural equation model analysis on the recovered data.Results:The interviewees believe that the current electronic medical record system is not complicated.The system is user-friendly,easy to use,and can find the desired information.The doctor’s work(task)involves multiple functions and modules of the system.The higher the doctor’s perceived task-technology fit,the higher the work performance and effective use level will be.After using the electronic medical record system technology,the process is simplified and the working efficiency is improved.The software and hardware upgrade of the hospital electronic medical record system brings techno-uncertainty,and doctors will get used to the new system after the adaptation period.The model was tested by SmartPLS3.0 software,and the results showed that except for the hypothesis H4 and H5 path coefficient P values less than 0.05,the research hypotheses have not been verified.The other path coefficient P values of other research hypotheses were all supported.The explanatory power of the model is also better.The results show that the research hypotheses except for "techno-uncertainty has a negative impact on the perception task-technology fit";and "techno-uncertainty has a negative impact on the effective use of the electronic medical record system",the path coefficient P values of other research hypotheses were all less than 0.05,which were all supported.The effective use of R2 in the electronic medical record system was 0.472,which was at a moderate level,but much higher than 0.25,indicating that the model’s explanatory ability was also good.Conclusions:The results of empirical research confirm:(1)The higher the innovative the doctor’s individual information technology,the higher the effective use of the electronic medical record system;(2)The higher the task interdependence,the higher the perceived task-technology fit;(3)The higher the task interdependence,the higher the effective use of the electronic medical record system;(4)The higher perceived task-technology fit,the higher effective use of electronic medical record system;(5)Perceived task-technology fit plays a partial role between task interdependence and effective use of electronic medical record system;(6)Perceived task-technology fit plays a partial role between techno-uncertainty and effective use of electronic medical record system.
