Information for patients and carers


CHI+MED (Computer-Human Interaction in Medicine) is a government-funded project to improve the safety of interactive (programmable) medical devices. By understanding more about how these devices are designed and used we can reduce medical errors and save lives.

The CHI+MED team are investigating the safety of medical devices (in particular infusion pumps) and studying how we can make them safer. On these pages you can find information for patients and carers on using devices safely, you can report a problem and read about patient safety in the news.

Medical errors are estimated to harm thousands of people in Britain every year. Preventable errors can cost people their lives, or livelihoods, and the financial burden is considerable. We are collecting examples of simple errors to highlight how easily they might be solved.

Using programmeable infusion pumps as an example, our team are learning what actually happens when errors occur in real situations and how they can be prevented. You can find out more about the different types of research we are undertaking, and the ways in which they link together, here. Please contact us if you would like to find out more about our research findings, or to share your experiences with respect to the safe use of medical devices.

Patients, carers and any member of the public can report a patient safety incident to the NHS's National Patient Safety Agency.
