UK (University of the West of England) AI to help people with type 2 diabetes manage their health
A Bristol-based team funded by the National Institute for Health and Care Research (NIHR) is developing a ground-breaking AI system designed with patients and their needs at its heart, to support people with type 2 diabetes in taking control of their health.
Structured diabetes education is a critical component of national efforts to improve health outcomes for people with the condition. The new software named ROMI (Relational Online Motivational Intervention) will deliver just that by providing patients with personalised accessible advice and support.
ROMI is a conversational AI that can deliver educational content – either verbally, as a text or as a graphic. Health care professionals and patients, including those from under-served communities which research shows have a higher prevalence of type 2 diabetes, will be involved in the design process from the start.
The team behind ROMI is made up of researchers from the University of the West of England (UWE Bristol) and the NIHR Bristol Biomedical Research Centre (NIHR Bristol BRC), and Elzware, a technology company that has been developing conversational AI since 2002.
Elzware has been awarded £134,000 from the NIHR for a year, to develop ROMI. The kind of AI being offered by Elzware avoids the pitfalls of systems like ChatGPT, making it safe for medical use.
New generative AI systems like ChatGPT represent a huge leap in the capabilities of machine-learning systems. However, in a health context, they are hard to make totally reliable. Also, their carbon footprint is very high. An older form, so called symbolic AI, is more reliable, but less flexible. Elzware’s approach is a hybrid of the two methods making it highly scalable with a reduced carbon footprint.
According to Diabetes UK, 3.6 million people in the UK are diagnosed with type 2 diabetes while another 13.6 million are at increased risk of developing it. This means that it’s becoming harder for patients to get the support they need. The NHS is looking for digital solutions to make diabetes care and support more accessible. Encouraging and educating patients on how to manage their condition can be difficult. ROMI aims to be an easy-to-use tool that is accessible whenever the patient needs it.
ROMI will be co-designed by people who have type 2 diabetes, healthcare professionals, researchers and Elzware’s technical team. Experts in patient and public involvement (PPI) will ensure that people with type 2 diabetes are represented at every stage of the project.
This approach will let the researchers understand what content users would find most helpful and put their needs at the centre of the development process. At the same time the healthcare professionals will input ideas of how to empower patients to be the expert in their own self-management. The team will then aim to trial ROMI among their target population to assess how effective it is at providing patients with health-improving advice.
The ROMI team includes researchers from the NIHR Bristol BRC, the Digital Cultures Research Centre at the University of the West of England, Aston University in Birmingham and the local NHS. As well as technical expertise, the team has PPI specialists, a psychologist, a diabetologist and a dietician.
Dr Andy Gibson, Associate Professor at UWE Bristol and PPI lead for the project, said: “I am really excited to have the opportunity to work with people with type 2 diabetes to create an AI system that is people driven rather than data driven.”
Dr Duane Mellor, registered dietician and Associate Dean for Public Engagement at Aston University, Birmingham, said: “It is great to be involved in this project as it will take the voices of people living with type 2 diabetes to understand what they need to know about food and diabetes and then build it into an AI system that adapts to the types of food their family and community eat and enjoy.”
Phil D Hall, principal investigator and Conversational AI Architect, said: “At a time when every news story about artificial intelligence seems to be apocalyptic, our project is doing things differently.”
The team
The principal investigator is Phil D Hall of Elzware Ltd. His company has 20 plus years’ experience in building compelling conversational systems.
The PPI team will be led by Associate Professor Andy Gibson of the University of the West of England and the NIHR Bristol BRC. Andy is a recognised national leader in the development of PPI methods.
Dr Duane Mellor, Associate Dean for Public Engagement in the College of Health and Life Science at Aston University, Birmingham, is a double award-winning registered dietitian and science communicator with a special interest in supporting people living with diabetes.
Dr Faisal Hasan is a Consultant in Diabetes and Endocrinology at Southmead Hospital. He will advise on clinical best practice.
Programme Director will be Rik Lander, who has had a long career making interactive and participatory media. He is a part-time Senior Lecture in Interface and Experience Design at the University of the West of England and is a member of the Digital Cultures Research Centre. His role is to make sure that ROMI is compelling for users so that they keep using it, leading to health benefits.
