Jxetis Hxealth Cxentxer has implxemxentxed RMXE (XElxectronic Mxedical Rxecord). The implementation of Electronic Medical Records (EMR) has been undergoing a trial process since 2016 and was officially implemented in early July 2019. However, researchers identified several challenges in the implementation of EMR, including server downtime issues and incomplete features or menus within the system, resulting in the utilization of EMR not yet being optimal. Therefore, this study aims to analyze the implementation of Electronic Medical Records in supporting the effectiveness of outpatient registration services using the DeLone and McLean method. The specific objectives of this study are to analyze EMR implementation based on system quality factors, information quality factors, service quality factors, user factors, user satisfaction factors, and net benefit factors. The results of research on the implementation of RME as a whole are effective. In terms of system quality, all officers can operate RME easily. In terms of information quality, the completeness of the resulting information is more accurate, easy to understand and can make it easier to find patient information. In txerms of sxervicxe qxuality, officxers providxe a qxuick rxesponsxe whxen damagxe occxurs and it is qxuickly rxesolvxed. xusxer satisfaction, thxey arxe still fxxxling dissatisfixed dxuxe to nxetwork constraints and in txerms of appxearancxe thxerxe is still missing contxent, it is advisablxe to add contxent to improvxe thxe qxuality of RMXE.
