Usability Study of an Electronic Medical Record From the Nurse Practitioners’ Practice: A Qualitative Study Using the Think-Aloud Technique

Introduction: Ensuring the usability of electronic medical records (EMRs) is crucial for healthcare providers to offer efficient, effective, and safe patient care. Nurse practitioners (NPs) are integral to the healthcare system and are essential in managing patient workflows. However, few studies assess NPs' perspectives on how EMR usage affects workflow and patient care quality. Method: In this study, the "think-aloud technique" was utilized for usability testing. It involves observing users (NPs) as they complete their everyday tasks on the EMR while vocalizing their thoughts and emotions. This method has been proven reliable and valid through various research, such as a systematic review. Results: The EMR system used by NPs can create a heavy cognitive workload, have limited functionality, can lead to unintended errors, and may experience technical difficulties. Conclusion: The EMR system used by NPs is challenging due to three main issues: high cognitive workload, limited system functionality, and technical problems. To improve the system, it is recommended to reduce the cognitive burden by customizing the user interface to fit the NPs' needs, enhancing the system's functionality by adding essential features and fixing any technical issues.
