Erratum: User Interface Problems of a Nationwide Inpatient Information System: A Heuristic Evaluation

AbstrakSistem informasi Teknik Informatika UMM memuat kegiatan berhubungan dengan akademik. Berdasarkan hasil observasi menggunakan kuesioner yang disebarkan ke 30 responden kepada mahasiswa aktif Teknik Informatika UMM, dari pernyataan ke empat bahwa 23 orang menyatakan meragukan data yang terdapat dalam sistem bukan informasi terkini dan jarang diperbarui. Kemudian interaksi yang dilakukan seperti penyampaian informasi mengenai jadwal kuliah, jadwal sidang, event dan informasi lainnya disampaikan melalui grup Facebook. Dengan adanya permasalahan tersebut maka peneliti menggunakan .metode User Centered Design (UCD) dalam perancangan prototype akademik dengan. memanfaatkan pendapat pengguna, serta pola. dan tingkah laku pengguna dapat .menghasilkan user interface dan fungsionalitas. yang maksimal serta memiliki nilai usabili.ty. Selain itu digunakan metode Heuristic Evaluation untuk melakukan evaluasi desain dan menilai sistem. Untuk menemukan kekurangan lebih awal sebelum di implementasikan, mengurangi kesalahan kegunaan berikutnya yang memungkinkan adanya pengeluaran biaya lebih untuk perbaikan. Abstract . Information System of Informatic engineegring UMM contains activities related to academics. Based on the results of observations using a questionnaire distributed to 30 respondents to UMM Informatics Engineering active students, from the fourth statement that 23 people expressed doubts the data contained in the system is not up-to-date information and rarely updated. Then interactions are carried out such as submitting information about class schedules, session schedules, events and other information delivered through the Facebook group. With these problems, the researcher uses the User Centered Design (UCD) method in designing academic prototypes by utilizing the opinions of users, as well as the patterns and behavior of users can produce maximum user interface and functionality and have usability value. In addition, the Heuristic Evaluation method is used to evaluate the design and assess the system. To find deficiencies early before they are implemented, reduce subsequent usability errors that allow for more expenses for repairs.

SummaryWhile studies have shown that usability evaluation could uncover many design problems of health information systems, the usability of health information systems in developing countries using their native language is poorly studied. The objective of this study was to evaluate the usability of a nationwide inpatient information system used in many academic hospitals in Iran.Three trained usability evaluators independently evaluated the system using Nielsen’s 10 usability heuristics. The evaluators combined identified problems in a single list and independently rated the severity of the problems. We statistically compared the number and severity of problems identified by HIS experienced and non-experienced evaluators.A total of 158 usability problems were identified. After removing duplications 99 unique problems were left. The highest mismatch with usability principles was related to “Consistency and standards” heuristic (25%) and the lowest related to “Flexibility and efficiency of use” (4%). The average severity of problems ranged from 2.4 (Major problem) to 3.3 (Catastrophe problem). The experienced evaluator with HIS identified significantly more problems and gave higher severities to problems (p<0.02).Heuristic Evaluation identified a high number of usability problems in a widely used inpatient information system in many academic hospitals. These problems, if remain unsolved, may waste users’ and patients’ time, increase errors and finally threaten patient’s safety. Many of them can be fixed with simple redesign solutions such as using clear labels and better layouts. This study suggests conducting further studies to confirm the findings concerning effect of evaluator experience on the results of Heuristic Evaluation.
