Moving Digital Health

Moving Digital Health: Dr. Raza Abidi of Dalhousie University

Episode Summary

Dr. Raza Abidi joins MindSeaCEO Reuben Hall to discuss artificial intelligence (AI), machine learning (ML), and the potential impact of these technologies for healthcare. With degrees in both electronics engineering and computer engineering, and a PhD in neural-network computer science, Dr. Abidi’s extensive experience in health informatics and his foundational training make him an excellent source of insight into the overlap between these fields.

Episode Notes

Professor of Computer Science and Professor of Medicine at Dalhousie University, Dr. Abidi serves as director of the Health Informatics graduate program and leads the university’s NICHE research group, bringing the benefits of knowledge management technologies to healthcare enterprises.

• Why more data is not necessarily better
• Why Dr. Abidi considers data collection the weak link in data quality
• Distinguishing between biases: which impact a model’s performance and which do not?
• Current NICHE team projects
• How the rise of e-therapeutics grew virtual care, and a crucial clarification of terms
• Barriers to digital health innovation, and countries/entities that are leading the way

Quotes  

• “The onset of digital health was the need to collect all the patient information and then make it available at the point of care.”
• “From a mindset standpoint, we have moved from that data-intensive digital health to more knowledge-and-services-oriented digital health.”
• “I think [the target] is: how can we actually use decision support to impact the operationalization of healthcare services?”
• “The entire reason for Explainable AI is to build trust, and once we build the trust, then the uptake of that decision model will actually be high. Otherwise, it will be used on and off, and there will always be ‘can I have a second opinion?’”
• “Biases come at two different levels, which we need to understand: Is it an ethical bias, or is it a bias that would affect the performance of the model?”
• “There are two sides of research: one is fundamental research, and one is applied research. And it is the fundamental research that is supported by these collaborations, because that is where we are asking the hard questions.”
• “One cannot discount the utility and applicability of artificial intelligence in health. It comes from all sides.”
