[1, 2]. Due to the important role of information systems in improving the quality of health care services, their evaluation from various aspects is important [3]. Usability evaluation is one of the most famous evaluations in the field of information systems and is considered an important method of measuring the quality of information technology [2] and is directly related to productivity [4, 5]. ... [6]. The International Organization for Standardization (ISO) has introduced the interaction principles in ISO 9241 and provided guidelines for the ergonomic design of interactive software [7]. Information systems usability evaluation has been less studied in Iran [8, 9]. The methods used to evaluate usability are variable [2, 5, 10-12]. One of the common tools in assessing the usability of information systems is the isometric questionnaire, which has been developed according to the ISO 9241 standard [13]. ... [14-17]. AIM (s) This study aimed to evaluate the usability of the hospital information system in one of the police medical centers. RESEARCH TYPE This is a descriptive cross-sectional study. RESEARCH SOCIETY, PLACE, AND TIME This study was performed in 2021 in one of the selected hospitals of Tehran, Iran police. All users of the hospital information system, including nurses, staff of the radiology unit, laboratory, emergency, surgery, pharmacy, and secretaries of the specialized unit were in the selected center of the statistical population of this study. SAMPLING METHOD AND NUMBER 110 users were selected through convenience sampling. USED DEVICES & MATERIALS Users' views on system usability were collected through an isometric questionnaire [18] (Table 1). In this tool, to prevent unrealistic answers, an "No opinion" option was added, which was a score equivalent to the "average" answer [13]. The reliability of the tool was 0.7 and the face and content validity of the questionnaire were confirmed by three medical informatics specialists. ETHICAL PERMISSIONS The questionnaires were provided to the users with the necessary permissions and the needed explanations were provided regarding the confidentiality of the information received from the participants. STATISTICAL ANALYSIS In addition to descriptive and analytical statistical methods, to find the relationship of work experience and degree of education with usability, analysis of variance (ANOVA) was used in SPSS 26 software. FINDING BY TEXT 110 people participated in the survey after distributing the questionnaires 23 of which were excluded due to the high number of unanswered questions or marking the option "No opinion" (N=87). The mean work experience of users was 10.62±14 years, with a minimum of less than one year and a maximum of 22 years. The distribution of users by occupation and degree was listed in Table 2. The mean score of all usability criteria in this study from the users' point of view was 3.23±0.36. Among the subjects, nurses had the highest satisfaction (3.44±0.36) and pharmacy users had the lowest satisfaction (2.41±0.11) from the information system (Table 3). Analysis of the variance test did not show any significant difference between the work experience of the subjects and the usability of the system. Similarly, no significant difference was observed between users' qualifications and usability. The degree of compliance of the studied information system with the ISO 9241-11 standard was shown in Figure 1 from the perspective of hospital wards users. MAIN COMPARISON TO THE SIMILAR STUDIES ... [19, 20]. The compliance of the studied system with the ISO 9241 standard was equal to 65%, which is to some extent consistent with the results of the study of Ehteshami et al. (67%) [21]. The mean score of all usability criteria in this study from the perspective of the users was 3.23±0.36 while, the mean scores obtained in the study of Mousavi et al. were 2.61, in the study of Safdari et al. 2.94, in the study of Moghadasi et al. 2.90 and the study of Ahmadi et al. 2.95 [14-17]. It seems that the situation of usability in the present study community is more favorable than in the communities of the mentioned studies. The system controllability criterion had the lowest score in this study, which is consistent with the results of the study of Kumar et al. (Figure 2) [22]. ... [23-25]. In the present study, the users of the pharmacy unit assigned the lowest score to all the criteria of usability of the hospital information system, which complied with the standard of ISO 9241, 48%. Therefore, contrary to the findings of Bayati et al.'s study, in this study, the status of the pharmacy information system was unfavorable from the perspective of users [24]. The greatest dissatisfaction of the users of this unit was related to the fit for work and then the fit for learning. Therefore, it is recommended to pay more attention to the usability aspects, especially to the mentioned items in developing the pharmacy information system. ... [26]. In this study, the mean score of fitness for work was moderate, which is in line with the findings of previous studies [14-17]. The most dissatisfaction among users with this criterion is related to the large number of different steps to do things. The software produced should be designed in such a way that it does not need to perform different steps to perform a specific task [13, 27]. From the users' point of view, the system self-description had the highest average score and the users' view of this criterion was a relatively more favorable situation than previous studies [14-17]. ... [28]. The subjects in this study had less satisfaction with program control compared to other usability criteria. Regarding this criterion, the findings of this study were relatively similar to Moqaddasi et al. (0.3), Safdari et al. (0.9), and Ahmadi et al. (10.3) [14, 16, 17]. While users in the study of Mousavi et al., were less satisfied with the controllability of the system under study (63.2) [15]. The greatest dissatisfaction of users was related to the requirement of the system to do things in a fixed and specific sequence, which makes users not have enough flexibility and does not speed up the current tasks. Users' views on other controllable metrics, such as ease of switching between pages, ease of calling processes, and the ability to stop activities when needed, were relatively favorable. ... [29, 30]. In the criterion of meeting the user's expectations, the average score was 3.30±0.51, which compared to Mousavi et al., Moghadasi et al., Safdari et al., and Ahmadi et al., the users of this study had a relatively more favorable view [14-17]. In the studies of Mousavi et al., Moghadasi et al., Safdari et al., and Ahmadi et al., the mean error tolerance score was in line with the present study, and users' views on this criterion were relatively favorable [14-17]. In the present study, the fit criterion for personalization after control had the lowest mean score (3.15±0.87). In all previous studies, this criterion has the lowest average score from the perspective of users [14-17]. Therefore, despite the average score of users to this criterion, the findings of the present study were in line with previous studies. It can also be inferred from the findings of this study and previous studies that the fit criterion for personalization has been neglected by the developers of hospital information systems in Iran. Another criterion examined in the present study was fitness for learning. ... [31, 32]. The average fit for learning in the study of Safdari et al. in the information system was relatively low (98.2) [16]. However, in the study of Moghadasi et al. as well as Rashidi et al., this criterion has obtained the highest average among other applicability criteria (12.3 and 37.4, respectively) [17, 33]. This average was 97.2 in the study of Ahmadi et al. And 7.2 in the study of Mousavi et al. according to the mean of 3.22±0.59 obtained in the present study, it can be inferred that the country's information systems in some cases have performed weakly for learning and in some cases have performed well. In this study, the lowest score on the fitness criterion for learning was related to the amount of detail needed to remember the correct use of the software. LIMITATIONS One of the limitations of this study was the inability to estimate the number of hospital information system users. On the other hand, due to some limitations, the tool used in this study was a modified version of the isometric questionnaire, however the use of the original version of the questionnaire could provide a broader view of the information system under study. SUGGESTIONS Based on the findings of this study, a list of suggestions that can be used to improve the usability and performance of the information system of the studied hospital is given in Table 4. It is also recommended that such evaluations be performed periodically in other medical centers to ensure the efficiency, productivity, and proper functioning of these systems. CONCLUSIONS Examination of the hospital information system of one of the police force medical centers in terms of usability according to the ISO 9241-11 standard showed that despite the desirability of some features of this system, it can be improved in some cases, including the ability to control and fit for personalization.
