Usability Evaluation of an Admission, Discharge, and Transfer Information System: A Heuristic Evaluation

Introduction: This study investigated the factors affecting the acceptance of hospital electronic health record (EHR) adoption by users based on Technology Acceptance Model3 (TAM3). Methods: The self-administered TAM3 questionnaire was used for data gathering. Content validity and reliability of the TAM3 questionnaire were measured. The relation between dependent, independent, and mediator variables was analyzed using multiple regression analysis. Results: The results from 224 users indicated that subjective norm, job relevance, output quality, voluntariness, computer experience have significant impacts on perceived usefulness. Also, perceptions of external control and computer anxiety were identified as having significant impacts on perceived ease of use. Perceived usefulness did not have a mediator role between result demonstrability and behavioral intention. Perceived ease of use was not found to be a mediating factor in the relationship between computer self- efficacy and behavioral intention, as well as perceived enjoyment. Conclusions: The findings of the current study, provide valuable scientific evidence for key affecting factors on hospital EHR in Iran as a developing country. Our results showed the main constructs and relationships depicted in the TAM3 were found to be applicable to assess the adoption of hospital EHR.

BACKGROUND: Hospital Information System (HIS) is a type of health information system which is widely used in clinical settings. Determining the success rate of HISs is an ongoing area of research since its implications are of interest for researchers, physicians and managers. AIM: In the present study, we develop a novel instrument to measure HIS success rate based on users’ viewpoints in a teaching hospital. METHODS: The study was conducted in Ebnesina and Dr Hejazi Psychiatric Hospital and education centre in Mashhad, Iran. The instrument for data collection was a self-administered structured questionnaire based on ISSM, covering seven dimensions, which includes system quality, information quality, service quality, system use, usefulness, satisfaction, and net benefits. The verification of content validity was carried out by an expert panel. The internal consistency of dimensions was measured by Cronbach’s alpha. Pearson’s correlation coefficient was calculated to evaluate the significance of associations between dimensions. The HIS success rate on users’ viewpoints was determined. RESULTS: A total of 125 users participated in the study. The instrument was validated by an expert panel with the Content Validity Index (CVI): 0.85 and Content Validity Ratio (CVR): 0.86. The overall Cronbach’s alpha value of the instrument was 0.93. The Pearson correlation coefficient showed significant positive relationships among the investigated dimensions. On average, HIS success rate in the hospital under study was 65% (CI: 64%, 67%). The dimensions of “usefulness”, “system quality”, and “net benefits” showed the highest rates of success, respectively. CONCLUSION: The instrument used in this study can be adopted for HIS evaluation in future studies. In the current study, a method was developed to determine the HIS success rate based on users’ viewpoints. This method allows for the comparison of HIS success rates in various hospitals. As well, our findings underscore the viewpoints of HIS users in a developing country.

“…Sistem informasi rumah sakit adalah salah satu website yang merupakan sistem teknologi informasi dan komunikasi yang memproses dan mengintegrasikan seluruh alur proses pelayanan dan kegiatan rumah sakit yang digunakan untuk memperoleh informasi secara tepat dan akurat [2]. Sistem informasi rumah sakit sebagai salah satu sistem layanan publik harus memiliki sisi usability yang baik agar pengguna tidak kesulitan dan dapat menggunakannya dengan benar sesuai dengan fungsinya [3]. Untuk mencapai hal tersebut, dibutuhkan evaluasi usability yang dapat membantu mengidentifikasi dan menganalisis masalah usability sebuah website.…”

Usability evaluation is needed to identify and analyze usability problems in an application. This study will compare the results of usability evaluation with Heuristic Evaluation and Cognitive Walkthrough methods on the SIMRS Del Egov Center web from the aspects of usability problems found, the level of usability problems, and end user responses that will be evaluated using usability testing to find a more effective method of finding usability problems. Heuristic Evaluation will refer to the 10 heuristic principles proposed by Jacob Nielsen, while Cognitive Walkthrough, the expert will follow the task provided by the researcher. The results showed that the results of the evaluation conducted by Heuristic Evaluation found more usability problems in aspects: efficiency, memorability and satisfaction, while Cognitive Walktrough found more usability problems in aspects: learnability and error. In the severity rating aspect, Cognitive Walktrough is more effective in finding usability problems with a higher severity level, with an average of 3, while heuristic evaluation with an average of 2. In the aspect of end user responses to websites based on usability testing, Heuristic Evaluation has a SUS score which is higher at 57, while Cognitive Walktrough has an SUS score of 54.5. This shows that based on these three aspects, the Heuristic Evaluation method is better at finding usability problems in the SIMRS Del Egov Center application study object.
