“…In two studies, the identified problems in this principle had the highest average severity. 21,38 Other studies have shown that the identified problems in this principle are among the major problems, 25,37 which are consistent with the results of the present study. The principle of error prevention is based on the fact that the design of the system should be such that it eliminates error-prone conditions.…”

“…According to the results, the principle of "consistency and standards" was the most frequent, which is consistent with the results of studies in the literature conducted on other health information systems. 21,25,29 Furthermore, this principle was in the category of major problems in terms of severity, and most of the problems identified in this principle were allocated to effectiveness. The consistency of the user interface can be physical, conceptual, or communicational.…”

“…Other studies have also shown that this principle had the highest average severity among usability problems of health information systems. [23][24][25]29 The problems of usability in this principle include visually nondistinct selected icons from other icons on the screen. In order to ensure effective use of a system, the system options and functions should be visible to users.…”

Nursing information system is a system that nurses are required to use in order to perform their daily activities. Poor user interface design of nursing information system can cause problems in nurses' interaction with the system. This research aimed to evaluate the usability of nursing information system. During this study, five evaluators examined the nursing information system with the heuristic evaluation method and by using the checklist of Nielsen usability principles. Then, the identified problems were categorized into 10 Nielsen usability principles, and the severity of the problems was determined. They also attributed each problem to one of usability attributes. A total of 104 unique problems were identified. Most of the problems were related to the principle of “consistency and standards.” More than a third of the identified problems were classed as major and catastrophe, with the highest severity in the average problems of “help and documentation” and “error prevention.” Most of the identified problems were attributed to effectiveness and satisfaction. Because a significant number of identified usability problems in nursing information system were major and catastrophe and were attributed to effectiveness and satisfaction, being able to remedy the problems could improve nurses' interaction with the system user interface and increase satisfaction and effectiveness of nurses.

“…Given the difference in computer experience and expertise of users and the unfamiliarity of information systems developers with the user population, the design of these systems is not often tailored to the needs and interests of their users. Also, according to previous studies [ 6 – 9 ], poor design of information systems leads to users' fatigue, and dissatisfaction, as well as, system inefficiency and rejection. The good design of an information system contributes to its usability.…”

Objective/aim Good design of cancer registry systems makes them easy to use, while poor design of their user interfaces leads to user dissatisfaction and resistance. The objective of this study was to evaluate the usability of a cancer registry system using Cognitive Walkthrough (CW) and to assess users' agreement with its usability problems. Methods CW was used to evaluate the registry system. We developed a checklist to help evaluators speed up the evaluation process, a problems form to collect the usability issues identified by the evaluators, and a problems severity form to determine the severity of problems by the evaluators. The problems were classified into two categories according to the CW questions and the system tasks. The agreement of the users with the system problems was examined by an online questionnaire. Users' agreement with the problems was then analyzed using the Interclass Correlation Coefficient in the SPSS 22 (Statistical Package for Social Science). Results In this study, 114 problems were identified. In the categorization of problems based on the CW questions, 41% (n = 47) of the problems concerned the issue of “users do not know what to do at each stage of working with the system”, 24% (n = 27) were classified as “users cannot link what they intend to do with system controls”, and 22% (n = 25) were related to “user's lack of understanding of the system processes”. Based on user tasks, about 36% (n = 41) of the problems were related to “removing patient duplication” and 33% (n = 38) were related to “registration of patient identification information”. User agreement with the problems was high (CI 95% = 0.9 (0.96, 0.98)). Conclusion System problems often originate from user ignorance about what to do at each stage of using the system. Also, half of the system problems concern a mismatch between what users want to do and the system controls, or a lack of understanding about what the system does at different stages. Therefore, to avoid user confusion, designers should use clues and guides on the screen for users, design controls consistent with the user model of thinking, and provide appropriate feedback after each user action to help users understand what the system is doing. The high agreement of users with the problems showed that in the absence of users system designers can use CW to identify the problems that users face in the real environment.
