A standard metric of technology usability, System Usability Scale (SUS) was utilized to summarize results. Results: A mean SUS score of 91.7 which is in the A grade meaning that the usability of the EHR was acceptable. Participants 44% reported that the EHR did not provided some of the features required for completion of tasks. Moreover, participants 75% reported the EHR did not provide good error messages whenever they made mistakes. Discussion: The perceived usability of the EHR was both useful and satisfactory. Both regular and intermittent users of the software would easily recover whenever they made mistakes. However, the EHR did not provide an attribute for the entry of the measurement for waist size yet it is an essential attribute for the diagnosis of diabetes mellitus. Also, the EHR did not provide opportunity for recording patient drug allergies, instead, had pre-recorded incomplete list of drug allergies. Conclusions: The usability of the EHR was acceptable except for the need to provide an attribute for waist and the need to provide good error messages and feedback to users. Moreover, the institution needs to address the challenge of workload experienced by the users of the EHR software.
