The user interface usability of the nursing information system (NIS) should be such that the nurses can learn and interact with it easily and quickly. Therefore, it is necessary to identify and solve the usability problems of these systems. The present study aimed to evaluate the usability of a NIS using the cognitive walkthrough (CW) evaluation method.
Based on five selected scenarios, five evaluators evaluated the NIS in Shafa Hospital Information System. After identifying the problems, the evaluators assigned each problem to one of the usability attributes. The severity of each identified problem was determined by the evaluators and five real users of the system.
In total, 24 unique problems were identified. The average severity of the problems was determined by the evaluators (2.77) and the actual users (2.82) in the "major problem" category. The highest number of problems were assigned to the scenarios 3 and 2 with 15 and 14 problems, respectively. The highest average severity in terms of evaluations and actual users was related to the scenario 5 (3.06 and 2.94, respectively), which was in the "major problem" category. The highest number of problems were associated with learnability (8 problems) and efficiency (6 problems).
Since most of the nurses do not have enough time for learning the system, and given that the selected scenarios for evaluation were based on the most frequent daily tasks that nurses performed using the NIS; The correction of usability problems in the scenarios 3 and 2 that had the highest number of problems and the scenario 5 that had the highest average severity and execution time; it can reduce the nurses' cognitive load and the learning time of the system and increase the efficiency of nurses.
护理信息系统（NIS）的用户界面可用性应使护士能够轻松、快速地学习和与之交互。因此，有必要识别和解决这些系统的可用性问题。本研究旨在使用认知遍历（CW）评估方法评估 NIS 的可用性。
基于五个选定的场景，五名评估员对沙法医院信息系统中的 NIS 进行了评估。在识别出问题后，评估员将每个问题分配给可用性属性之一。评估员和系统的五名实际用户确定了每个已识别问题的严重程度。
共确定了 24 个独特的问题。评估员（2.77）和实际用户（2.82）将问题的平均严重程度确定为“主要问题”类别中的严重问题。问题最多的是场景 3 和 2，分别有 15 个和 14 个问题。评估和实际用户的平均严重程度最高的是场景 5（分别为 3.06 和 2.94），属于“主要问题”类别。与可学习性（8 个问题）和效率（6 个问题）相关的问题最多。
由于大多数护士没有足够的时间学习系统，并且所选的评估场景基于护士使用 NIS 执行的最常见的日常任务；纠正场景 3 和 2 中问题最多、场景 5 中平均严重程度和执行时间最高的可用性问题；可以减轻护士的认知负担和系统的学习时间，提高护士的工作效率。
