When life鈥檚 everyday challenges get in the way, it can be hard to stay on track with antiretroviral therapy. A new chatbot could help.
World AIDS Day, which was observed on December 1, is a global initiative to raise awareness about HIV and AIDS, which affect nearly 40 million people worldwide. At the 9I制作厂免费 Health Centre (MUHC) and the Research Institute of the 9I制作厂免费 Health Centre (The Institute), physicians and researchers are leading efforts to improve the lives of people living with HIV, by promoting adherence to antiretroviral therapy (ART) to maintain long-term suppression of the virus, prevent complications and avoid further transmission.
Among them is聽, Assistant Professor at the Department of Family medicine, physician at the MUHC鈥檚 Chronic Viral Illness Service (CVIS) and a Scientist in the聽聽at The Institute.
Dr. Lebouch茅 leads a research team developing the first AI-powered chatbot designed to help people with HIV manage their health. Called MARVIN, this bilingual tool can provide reliable health information, medication reminders and guidance on managing antiretroviral therapy, through brief text-based conversations. A study recently published in聽聽demonstrated MARVIN鈥檚 effectiveness.

鈥淎dvances in antiretroviral therapy have revolutionized HIV care, giving people with HIV nearly the same life expectancy as those without the virus. But to maintain this progress, it鈥檚 critical to stay on top of treatment. Our ultimate vision is for MARVIN to become a personalized health companion, delivering the right support to the right person at the right time, redefining the future of HIV care,鈥� says Dr. Lebouch茅, who is also Associate Professor in the Department of Family Medicine at 9I制作厂免费.
In the study, 28 patients from the CVIS clinic engaged in 20 conversations with MARVIN over three weeks, covering predetermined topics. Participants provided feedback on the tool鈥檚 usability through surveys, and nine were interviewed for deeper insights. Users praised MARVIN for its reliable, real-time health information, easy accessibility, and conversational approach. Its confidentiality and non-judgmental nature made it a trusted space for discussing sensitive issues.
鈥淭he positive feedback on MARVIN showcases the potential of AI-powered tools to empower patients in managing their care. It underscores the value of integrating patient perspectives to develop human-centered technologies that truly meet their needs,鈥� says Yuanchao Ma, Ing. PRT and PhD candidate, project manager and first author of the study, research assistant at The Institute鈥檚 Centre for Outcomes Research (CORE) and research associate at Polytechnique Montr茅al.
The study was conducted by a multidisciplinary team of healthcare professionals from the CVIS and researchers from the CORE. Technical development was supported by students and interns from Polytechnique Montr茅al, while a Patient Expert Committee provided clinical insights. The researchers are continuing to refine and evaluate MARVIN to enhance its impact further.
