AVACHAT: Co-design of an artificially intelligent virtual agent to support self-management in individuals with complex physical comorbidities 

In this research project we have brought together expertise from three themes within the 

YH CLAHRC: Telehealth and Care Technologies, Mental Health and Comorbidities and Translating Knowledge into Action.

Problem:

Individuals with physical long term health conditions are at a greater risk of experiencing common mental health problems, such as anxiety and depression, than are members of the general population. Not everyone who would benefit from support is able to access it; as supply of services is failing to meet demand. So patients are increasingly being encouraged to self-manage their health in their own homes. Managing your own health well can have significant positive implications, personally and economically.


What we are doing about it:

Digitally technology may be able to support people to better self-manage their physical and emotional health. One potential technology for the delivery of personalised care is the autonomous virtual agent with speech-based natural language processing abilities.  We are working with patients, health professionals and an interdisciplinary team of researchers to co-develop the scope, content and functionality of an autonomous virtual agent prototype to support self-management for patients with an exemplar long-term condition (Chronic Pulmonary Obstructive Disease, COPD).

Workshops

We have now conducted two co-design workshops with patients, health professionals and computer scientists. In the first workshop we explored challenges of daily living and ways in which these challenges could be overcome. We critiqued existing avatar examples and designed our own ideal avatar.   

In the second workshop we role-played scenarios in order to develop content for the system. Finally, we conducted a proof-of-concept implementation, which was used in a video-based scenario testing of acceptability with older adults with a diagnosis of COPD and health professionals connected

with this patient group’s care in order further develop the prototype.

What does this mean?
The prototype autonomous agent has been developed through co-design techniques. Future research is planned to further develop and evaluate the system for a range of patient samples and care settings. Clinical applications are broad. The impact of such a system could include personal gains in self-efficacy and self-confidence, reduction in social isolation, increased illness knowledge and better coping mechanisms. Clinical gains could include fewer exacerbations of condition and a decrease in unnecessary formal healthcare service utilisation.
