Preventive Health with ChatIRIS: Integrating InterSystems IRIS for Enhanced Patient Engagement

ChatIRIS Health Coach, a GPT-4 based agent that leverages the Health Belief Model as a psychological framework to craft empathetic replies.

Why is it useful? In Singapore, less than 1 in 4 go for annual vaccinations. Only a third of eligible adults are screened for common cancers. Convincing people to be vaccinated or screened for cancer will benefit from a personalised approach, but empathetic conversations are difficult to scale.

How should it work? The Health Belief Model suggests that individual health behaviours are shaped by personal perceptions of vulnerabilities to disease risk, alongside the perceived incentives and barriers to taking action.

Our approach disaggregates these concepts into 14 distinct belief scores, allowing us to dynamically monitor them over the course of the conversation.
In the context of preventive health actions (e.g. cancer screening, vaccinations), we find that the agent is fairly successful at picking up a person’s beliefs around health actions (e.g. perceived vulnerabilities and barriers). We demonstrate the agent’s capabilities in the specific instance of a colorectal cancer screening campaign.
