User-centered design of ERCP teleguidance

Abstract

We are designing a novel telemedicine service, where an experienced endoscopist at a central site can guide endoscopists at remote hospitals during procedures (mainly ERCP). This can be done simultaneously to several hospitals at once, using several displays in a control room setting. As this is a new way of working, we design the teleguidance room at the same time as we learn about user needs. We have conducted field studies and created scenarios to gain knowledge about the usage context and target groups, and we have used mock-ups and high-fidelity prototypes to evaluate the usage situations. The user-centered design activities have helped to articulate user needs, surface technical difficulties, iterate design solutions, create a shared understanding of the telemedicine service within the project team, and prepare for implementation in clinical work.
