ABSTRACT

The End-User Capability Toward Explorative/Exploitive Use and End-User Performance in Hospital Information System

By Choi, Kwang Seok Advisor : Prof. Lee, Dae Yong, Ph. D. Department of Management Information Systems Graduate School of Chosun University

This research studies how the user capability in a hospital information system affects both the system usage and the user’s individual performance. For the user’s explorative and exploitive capability analysis, all the relevant factors that seemingly affect the capability are grouped into the following three factor categories: organizational factor group, EMR(Electronic Medical Records) system factor group and work environment factor group. The organizational factor group further consists of the top managerial support factor and education/training factor, while the EMR system factor group is made of system quality, information quality and IT department’s service quality factors and the work environment factor group has the work-system relevancy and work overload factors as its elements. This study tests the following hypotheses: the user's explorative and exploitive capability influences the explorative and exploitive usage of the hospital information system, the explorative and exploitive usage of the hospital information system influences both an EMR system's performance and individual user satisfaction. This study conducted a survey for 530 doctors, nurses and administrative workers from 7 200-bed or more hospitals including the Chosun University Hospital. This research model using the 480 statistically-effective answers from the survey, this study finds with statistical significance that both the organizational, EMR system and work environmental factors all influence the user's explorative and exploitive capability. This research also finds that the user's exploitive capability significantly influences the user's explorative capability and the user's exploitive usage while the user's explorative capability significantly influences both the user's exploitive and explorative usage. It further finds that the user's exploitive usage significantly influences the user's explorative usage, EMR performance and the user satisfaction while the user's explorative usage significantly influences the user satisfaction only. Based on the above findings, this study suggests several key important points from both theoretical and practical perspectives regarding the way the user's capability in the hospital information system influences the system usage and the user's performance.
