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.
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.
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.
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.
确保电子病历（EMR）的可用性对于医疗保健提供者提供高效、有效和安全的患者护理至关重要。执业护士（NP）是医疗保健系统不可或缺的一部分，在管理患者工作流程中起着至关重要的作用。然而，很少有研究评估执业护士对电子病历使用如何影响工作流程和患者护理质量的看法。
在本研究中，采用“出声思维技术”进行可用性测试。该方法包括观察用户（执业护士）在电子病历上完成日常任务时说出他们的想法和感受。通过各种研究，如系统评价，已证明该方法可靠且有效。
执业护士使用的电子病历系统可能会造成沉重的认知负担，功能有限，可能导致意外错误，并且可能会遇到技术困难。
由于三个主要问题，执业护士使用的电子病历系统具有挑战性：认知负担重、系统功能有限和技术问题。为了改进该系统，建议通过定制用户界面以满足执业护士的需求来减轻认知负担，通过添加基本功能和解决任何技术问题来增强系统功能。
