Human Computer Interaction and medical devices

Abstract

To achieve dependable, usable, and well-engineered interactive devices in healthcare requires applied Human Computer Interaction (HCI) research and awareness of HCI issues throughout the lifecycle, from design through to procurement, training and use. This paper shows that some healthcare devices fall far short, and thus identifies a gap in applied HCI. We use a basic, interactive hospital bed as a case study, arguably so routine and simple enough that there should have been very few problems. However, the bed’s interactive control panel design violates standard HCI principles. It is also badly programmed by the manufacturer. Evidently, something has gone wrong, somewhere from design to procurement, and we argue most of the problems would have been managed or avoided by conventional HCI processes. Driven by the case study, this paper explores the problems and makes recommendations. There are many similarly poorly designed medical devices. Manufacturers and healthcare purchasing groups should adhere to HCI processes and guidelines, as well as those provided by regulatory agencies for the design, regulation, and procurement of devices, products, or systems that contribute to patient safety. The challenge is to make HCI knowledge and priorities available to and effective in this important domain in any places that can make a difference.
