While medical device design standards provide a vital framework, they are not sufficient on their own. Manufacturers often find themselves isolated in their development efforts, leading to challenges in communication and usability. This paper discusses methodologies to integrate human factors, including personas, experimental design, and rational trade-offs. It emphasizes that understanding real-world usage scenarios and fostering collaboration are crucial to overcoming the limitations of existing standards in medical device design, particularly for infusion pumps and similar technologies.

  1. Medical Device Design Standards: Necessary But Not Sufficient Chris Vincent & Ann Blandford UCLIC, University College London, Gower Street, London, WC1E 6BT, UK c.vincent@ucl.ac.uk, a.blandford@ucl.ac.uk There are many standards, applied to support infusion pump design and manufacture: • WE HAVE BEEN SUPPORTING MANUFACTURERS AND CONSULTANCIES IN THE FOLLOWING WAYS • www.chi-med.ac.uk • Personas and scenarios: Avoid designing in isolation by considering hypothetical users and usage [3]. • Number entry guidance: Conducting experiments to reveal the pros and cons of candidate design options. • Design rationale: Provide techniques to articulate trade-offs and make apparent the reasoning behind design [4]. • Guidance for standards: Provide an overview of the pros and cons of different approaches. • BUT…. There are reasons why we need more than just standards: • Devices are being used outside hospitals, and in ways that are hard to anticipate [1]. • 2) Despite standards, design and development occurs in isolation [2]. • 3) Guidance / standards can be contradictory. Care outside of the hospital Care in the hospital “In many cases, the development landscape resembled multiple islands of individuals, maintaining they had little influence over the device UI…” “UE/HFE practitioners still reported discipline specific silos.” “So everything that fosters communication helps. and stuff that prevents communication doesn’t.” A guide to the design of electronic infusion devices: NPSA / NHS England.
