EMR implementation in the hospital could be beneficial in several aspects while there are some limitations after digital transformation. After using EMR, health expenditure could be claimed from universal health insurance and the other two major insurances accurately and timely compared to the paper-based system. Registration procedure and space for collecting the registration card is reduced. Error from mismatching both patient identification and the test result are decreased. Moreover, EMR could early alert to inappropriate treatment such as drug allergy or fatal drug interaction prescribing. However, EMR could reduce the interaction between clinician and patients. Data confidentiality, integrity and availability are not well concerned in the current EMR system which makes data loss or open to unauthorized users. To conclude, EMR is useful in several ways yet it is needed to be improved to minimizing the limitations.
