Drug Order Entry (DOE) is one of the most important components in Electronic Medical Records System (EMR).Doctor’s appropriate order of drugs via DOE is very important to reduce consultation hour per patient and medical errors.Keystroke-Level Model (KLM) was employed to estimate the doctor’s quickness and effort while performing DOE at two public hospitals in Malaysia.Observation method was used in this study.The results showed that the proposed scenario represents the DOE behaviours well, and confines to the doctor’s workflow, easy to be understood and navigated, hence increases the efficiency of the EMR, reduce medical errors, and increases the acceptance level of the system
