Usability Engineering Recommendations for Next-Gen Integrated Interoperable Medical Devices

This article reports on the development of usability engineering recommendations for next-generation integrated interoperable medical devices. A model-based hazard analysis method is used to reason about possible design anomalies in interoperability functions that could lead to use errors. Design recommendations are identified that can mitigate design problems. An example application of the method is presented based on an integrated medical system prototype for postoperative care. The AAMI/UL technical committee used the results of the described analysis to inform the creation of the Interoperability Usability Concepts, Annex J, which is included in the first edition of the new ANSI/AAMI/UL 2800-1:2019 standard on medical device interoperability. The presented work is valuable to experts developing future revisions of the interoperability standard, as it documents key aspects of the analysis method used to create part of the standard. The contribution is also valuable to manufacturers, as it demonstrates how to perform a model-based analysis of use-related aspects of a medical system at the early stages of development, when a concrete implementation of the system is not yet available.

Usability Engineering and HCI for Promoting Root-Level Social Computation and Informatics Practice

Human-computer interaction talks about designing IT and computing technologies in the context of man-machine interaction. Man-machine interaction (MMI), human-machine interaction (HMI), usability experience design, human-centered designing, user-centered designing are the related areas and responsible for the designing and development of interface of electronics products viz. computers, laptops, systems, mobiles, smart phones, etc. Educational and training is important for the social as well as economic development in several contexts. Knowledge delivery system is the reason for development and also developed nation. A few current and emerging technologies which include big data management, cloud computing, green computing, data science, internet of things (IoT) are also allied with HCI and usability engineering in different contexts. India is a developing country, and more enhancement is possible with integration of IT. In the developed countries, various educational degree and training programs are running at Bachelors, Masters, and Doctoral degrees in the areas of HCI and usability engineering, but in a country like India, such programs are missing. In this conceptual paper, a few aspects of usability engineering and HCI have been explored for creating true IT-enriched society. The paper is also proposed some possible and future potential programs for a healthy social informatics world.

A Design of Mobile Application for Ultrasound Bladder Monitoring System Based on Usability Engineering

Patients with voiding dysfunction need continuous treatments as well as bladder ultrasonography, surgical procedures and medication. Ultrasound bladder monitoring healthcare system can help non-invasive treatment as a bladder training. This system uses wearable patch sensor so that patients can monitor their bladder volume as an indicator of voiding and be recommended voiding at a proper time. In this study, the mobile application for the system is designed and evaluated based on optimized clinical workflow and safety. This study included the design of clinical application models for users and the development of user interface complying with usability engineering process.

Developing a Smart Infusion Pump Dedicated to Infusion Safety

A large-volume infusion pump is a medical device with a big job: infuse patients with life-sustaining fluids and medications at a known and controlled rate. And, do it safely. Because infusions are frequently administered therapies, the opportunity for use error–induced adverse events is amplified. To develop a safer infusion pump, Ivenix, Inc., committed to a comprehensive usability engineering effort that included over 400 hours of usability testing. As a result, the pump’s design includes risk controls for mitigating potential use errors not available on today’s pumps. The resulting product was the winner of the 2019 Stanley Caplan User-Centered Design Award.
