“…User-centered design encompasses the involvement of all relevant stakeholders in iterative design steps having an appropriate view on the requirements of tasks, users, and task distribution [73]. If user-centered design is applied, this can result in better acceptance of users [93], higher satisfaction [94], improved usability [95], and less training needs [96]. The iterative design loop of DIN EN ISO 9241-210 includes an analysis of system usage context, followed by a deduction of requirements and the development of a design solution that is evaluated afterwards.…”

Current Air Traffic Controller working positions (CWPs) are reaching their capacity owing to increasing levels of air traffic. The multimodal CWP prototype TriControl combines automatic speech recognition, multitouch gestures, and eye-tracking, aiming for more natural and improved human interaction with air traffic control systems. However, the prototype has not yet undergone systematic evaluation with respect to feasibility. This paper evaluates the operational feasibility, focusing on the system usability of the approach CWP TriControl and its fulfillment of operational requirements. Fourteen controllers took part in a simulation study to evaluate the TriControl concept. The active approach controllers among the group of participants served as the main core target subgroup. The ratings of all controllers in the TriControl assessment were, on average, generally in slight agreement, with just a few showing statistical significance. However, the active approach controllers performed better and rated the system much more positively. The active approach controllers were strongly positive regarding the system usability and acceptance of this early-stage prototype. Particularly, ease of use, user-friendliness, and learnability were perceived very positively. Overall, they were also satisfied with the command input procedure, and would use it for their daily work. Thus, the participating controllers encourage further enhancements to be made to TriControl.

“…There is wide variation across healthcare organisations and EP system vendors in how on-screen safety information is presented to prescribers, with no clear guidelines derived from studies or best practice recommendations. We know from previous recommendations that placement and visibility and prioritization of information in the design of UI should be customized based on the system [28], and that the colour of alerts or general text information should function as a risk indicator [29,30], while UI consistency (e.g. buttons that perform the same action and that have the same purpose) is advised to avoid medication errors [10,12].…”

Background: User interface (UI) design features such as screen layout, density of information, and use of colour may affect the usability of electronic prescribing (EP) systems, with usability problems previously associated with medication errors. To identify how to improve existing systems, our aim was to explore prescribers' perspectives of UI features of a commercially available EP system, and how these may affect patient safety. Methods: Two studies were conducted, each including ten participants prescribing a penicillin for a test patient with a penicillin allergy. In study 1, eye-gaze tracking was used as a means to explore visual attention and behaviour during prescribing, followed by a self-reported EP system usability scale. In study 2, a think-aloud method and semi-structured interview were applied to explore participants' thoughts and views on prescribing, with a focus on UI design and patient safety. Results: Study 1 showed high visual attention toward information on allergies and patient information, allergy popup alerts, and medication order review and confirmation, with less visual attention on adding medication. The system's usability was rated 'below average'. In study 2, participants highlighted EP design features and workflow, including screen layout and information overload as being important for patient safety, benefits of EP systems such as keeping a record of relevant information, and suggestions for improvement in relation to system design (colour, fonts, customization) and patient interaction. Conclusions: Specific UI design factors were identified that may improve the usability and/or safety of EP systems. It is suggested that eye-gaze tracking and think-aloud methods are used in future experimental research in this area. Limitations include the small sample size; further work should include similar studies on other EP systems.

“…Research shows that a UCD process increases the usability of applications in health care and thus can improve the productivity of systems, their accessibility, and reduces the risk of harm. [19][20][21] This article describes for the first time the development of Web-based online platform for pediatric dosing recommendation in Germany. The specific purpose of this article is: (1) to survey the demand of physicians for an evidence-based knowledge base, to check to what extend the requirements are fulfilled, and which new requirements arise, and (2) to assess a prototype of an online platform with end users in terms of usability and functionality.…”

User-Centered Development of an Online Platform for Drug Dosing Recommendations in Pediatrics

Background Drug therapy in pediatric patients is a complex process. Children are subject to continuous growth and variation in drug-metabolizing enzyme activity, requiring continuous adaption of dosages. In Germany, currently no publicly available database exists that provides evidence-based information on drug dosages in pediatrics. For local drug dosing support, a prototype database has been developed within the Children's Hospital, Erlangen. A user-centered development process was initiated to establish an online platform for evidence-based dosing recommendations, as well as pharmacological and pharmaceutical drug information in pediatrics. Objectives The objectives of the study were to survey the demand for such a platform and to assess the usability of the different versions of the developed system. Methods The developed prototype was evaluated in a pluralistic walkthrough with prospective end users. After a redesign, the second prototype of the online platform underwent an online usability testing based on a tailored questionnaire and the System Usability Scale (SUS) (n = 12). Results Eleven of 12 participants expressed a demand for an online platform for pediatric dosing recommendations. The majority of the participants requested the integration of extended features, such as drug–drug interaction alerts, or information on adverse effects, pharmacokinetics, and pharmacodynamics. Particularly noteworthy is the demand for an online calculator; 5 of a total of 15 participants explicitly requested a calculator for dosages (based on age, weight, body surface) and glomerular filtration rate. The usability of the second prototype was rated “good to excellent” with a median SUS of 81.25. Conclusion Local domain experts demand an online platform for pediatric dosing recommendations. The application of the user-centered design approach enabled the development of a prototype suitable for practical use. Multiple additional required functionalities have been identified, whereby the importance of an online calculator for patient–individual dosing recommendations was particularly emphasized.
