We are focusing on the interaction between people and medical devices. The devices provide a common focus for all strands of our research. We are studying the device design, human cognition (particularly focusing on errors), and the situations in which devices are used: hospitals and homes. We are developing methods to support better design and procurement decisions, and we are engaging with stakeholders to change culture and practices where possible.
Understanding context
Understanding people
In a second strand of research we are conducting laboratory experiments to understand why people make mistakes. What are the underlying cognitive causes of different kinds of errors and which solutions are most effective? For example, an early CHI+MED project is looking at the ability of people to resume what they were doing after being interrupted. We have shown that people are more likely to resume at the correct point if they take a few seconds to look at the interface rather than resuming quickly.
We have initiated a series of projects that are already delivering results both in terms of the basic science and its useful application. They are organised into the four major themes of CHI+MED: clinical situations, device design, cognition and stakeholders.
We are gaining a deep understanding of the situations and environments in which medical devices are used, whether in hospital or home settings. We will then build on this understanding by exploring ways to support doctors, nurses and patients to avoid and recover from errors.
Understanding the way medical devices are really used
We also need to understand the ways in which the design of a device can help people avoid making errors. Good device design can also help people 'undo' an error they've made before a problem arises.
