A quality criterion for evaluating information systems (ISs) is their usability, which can be determined by examining the user interface. User interface issues may generate user errors, dissatisfaction, and inefficiency, making IS adoption difficult. Therefore, the International Standard Organization recommends usability testing to evaluate IS acceptability and deployment. So, this study aimed to develop a native model for the usability testing of hospital information systems (HISs) via heuristic evaluation (HE).

This multi-staged qualitative study was conducted in 2020; ScienceDirect, PubMed, Web of Science, Scopus, Civilica, and Magiran databases were searched. After meeting the inclusion criteria, the articles were scored. Then, the initial model was created in the following stage by extracting data from library sources and validated using the Delphi technique, and consequently, the final model was presented.

: The native model was developed using thirteen principles: 1) visibility of system status, 2) the match between the system and the real world, 3) users’ control and freedom, 4) consistency and standards, 5) error prevention, 6) recognition rather than recall, 7) flexibility and efficiency of use, 8) aesthetic and minimalist design, 9) helping users recognize, diagnose, and recover errors, 10) documentation and help, 11) skill , 12) pleasurable, respectful interaction with users, and 13) privacy protection.

This study demonstrated that localizing the usability evaluation of HISs based on trustworthy sources and HE is a wise strategy, because not only it avoids repetitive processes, but also it uses the best up-to-date resources to enable the presentation of the highest evaluation quality.

Considering the importance of Mobile Health (mHealth) in improving the quality of health services, evaluating the performance of applications that provide these services seems necessary. One of the dimensions of assessing applications is usability evaluation. This study aimed to evaluate the usability of a home health services mobile application (30Teb) using the heuristic evaluation method.

The present study was an applied cross-sectional one. The usability of the user interface of the 30Teb home health services mobile application to provide health services in Kerman was evaluated using a heuristic evaluation checklist. In this study, three evaluators independently evaluated the user interface of the 30Teb mobile app.

A total of 241 problems were identified by three evaluators. After deleting duplicates and then summarizing them, 69 problems remained in the final list. The highest number of identified problems was related to the “identification instead of reminder” and “skills” components, and the lowest number was related to the “privacy” component. Moreover, the highest severity of the identified problems was related to the component of “user freedom and control of the system,” and the lowest severity was related to the “privacy” component.

Although the problems identified in the 30Teb app were not very severe, paying attention to them in different design and implementation stages and solving these problems can lead to better user interaction and more effective use of a mobile application.

Poor User Interface design can be one of the probable reasons of users’ error and reduced incentive in using health information systems such as PACS. Heuristic evaluation is one the methods for assuring the proper user interface design of health information systems such as PACS.

This study was a descriptive-analytic research conducted in 2019 through using Nielsen usability checklist. The study setting was Zanjan University of Medical Sciences and data were analyzed in SPSS 25 using descriptive statistics.

In whole, 130 problems were found in 293 usability cases. The most common usability problems include privacy (66.66%), Visibility of System Status (65.52%), and Flexibility and Minimalist Design (60%) and the lowest number of UI design problems were associated with the Pleasurable and Respectful Interaction with the User (14.29%).

Usability Evaluation can identify the reasons of problems that may cause medical errors or users' resistance in working with the system. Therefore, it is necessary for system developers whose systems are widely used in important centers to pay more attention to all standards in designing the system and to prevent the occurrence of errors.

Admission and medical record system (AMRS) is one of the most important subsystems of hospital information system, which is used by many users in admission, discharge, and health information management. Interface usability problems can reduce user speed, precision, and efficiency in user-system interaction. This study aimed to identify the usability problems of AMRS in a hospital information system.

In this descriptive cross-sectional study, five health information technology experts evaluated AMRS in a hospital information system using heuristic evaluation. Then, the system usability problems were categorized according to Nielsen's 10 usability principles and their severity were determined.

Totally, 62 unique usability problems were detected. The most frequent problems were related to "consistency and standards" (n=9) and ''recognition rather than recall" (n=9), and the least frequent ones was related to "flexibility and efficiency of use" (n=1). 59.7% of the identified problems were categorized as big and severe problems. The highest average severity of problems belonged to "system’s visibility" and "aesthetic and minimalist design", and the least average severity belonged to "error prevention".

Using heuristic evaluation, a large number of usability problems in AMRS were identified. According to experts' opinions, most of the HIS interface problems were big and severe, and they need to be modified by designers and developers of these systems.

Physiotherapy information system is one of health information systems that is used to increase the efficiency and effectiveness of physiotherapy department. Studies have shown that due to usability problems, user interaction with some information systems is difficult. The objective of this study is to evaluate user interaction problems with physiotherapy information system. This study is a cross-sectional, descriptive research which is done using heuristic evaluation method. In this study the user interaction problems of a physiotherapy system using in 105 hospitals were identified, classified and rated based on their severities by three evaluators. Data were gathered using a data collection form designed in Excel. In this study 82 unique interactive problems were identified. Most of them with 28% (n=23) were related to unconformity of system design with real world conventions. The mean severity of these problems was major. The lowest numbers were related to the problems; lack of help and documentation in the system and error prevention, with major and minor severity respectively. A number of systems, which are used in many health care centers, such as evaluated system in this study suffer from several problems that endanger user interaction with the systems and can lead to error and patient harm. To identify and eliminate this sort of problems we recommend that usability evaluation of these systems to be carried out regularly to enhance users satisfaction, workflow and patient safety.

Owing to t he critical importance of emergency department activities in saving lives، information systems of this department should be free of fault to prevent the incidence of errors. Usability evaluation methods are used to assess this quality measure. Heuristic evaluation is one of the methods which identifies usability problems with minimum amount of time، cost and resources. The objective of this research was to evaluate the usability of emergency department admission subsystem of health information systems in Mashhad University of Medical Sciences. Using Nielsen’s 10 usability principles، three trained evaluators، independent of each other، evaluated the corresponding subsystem and determined the severity of identified problems. All the problems، identified by independent evaluators، were collected in a single list and the mean severity of each problem was calculated. A total of 163 usability problems were identified. The lowest mismatch with usability principles was related to “error prevention” (3 %) and the highest was related to “consistency and standards” (27 %). The average severity of problems varied from 2. 3 (minor problem) concerning “system''s visibility” to 2. 9 (major problem) concerning “help users recognize، diagnose، and recover from errors”. Heuristic Evaluation can be used to identify a high number of usability problems related to health information applications in health care systems. If remain unsolved، these problems may waste users’ and patients’ time، increase errors، reduce data quality، and in general، threaten patient’s safety.
