There are various approaches to evaluating the usability of electronic medical record (EMR) systems. User perspectives are an integral part of evaluation. Usability evaluations efficiently and effectively contribute to user-centered design and supports tasks and increase user satisfaction. This study determined the main usability requirements for EMRs by means of an end-user survey.
A mixed-method strategy was conducted in three phases. A qualitative approach was employed to collect and formulate EMR usability requirements using the focus group method and the modified Delphi technique. Classic Delphi technique was used to evaluate the proposed requirements among 380 end-users in Iran.
The final list of EMR usability requirements was verified and included 163 requirements divided into nine groups. The highest rates of end-user agreement relate to EMR visual clarity (3.65 ± 0.61), fault tolerance (3.58 ± 0.56), and suitability for learning (3.55 ± 0.54). The lowest end-user agreement was for auditory presentation (3.18 ± 0.69).
The highest and lowest agreement among end-users was for visual clarity and auditory presentation by EMRs, respectively. This suggests that user priorities in determination of EMR usability and their understanding of the importance of the types of individual tasks and context characteristics differ.
评估电子病历（EMR）系统可用性有多种方法。用户视角是评估的一个组成部分。可用性评估能高效且有效地促进以用户为中心的设计，支持各项任务并提高用户满意度。本研究通过终端用户调查确定了电子病历的主要可用性要求。
采用混合方法策略，分三个阶段进行。运用焦点小组法和改进的德尔菲技术，采用定性方法收集和制定电子病历可用性要求。使用经典德尔菲技术在伊朗的380名终端用户中评估所提出的要求。
电子病历可用性要求的最终清单得到验证，包括163项要求，分为九组。终端用户同意率最高的是电子病历的视觉清晰度（3.65±0.61）、容错性（3.58±0.56）和易学性（3.55±0.54）。终端用户同意率最低的是听觉呈现（3.18±0.69）。
终端用户同意率最高和最低的分别是电子病历的视觉清晰度和听觉呈现。这表明在确定电子病历可用性时用户的优先事项以及他们对各项任务类型和情境特征重要性的理解存在差异。
