On/Offcall: AI in Healthcare Use Cases of the Future

Welcome back to On/Offcall!

Happy new year! To kick off 2026, we welcomed one of the most sought after physician technology leaders in the world to How I Doctor: Dr. David Rhew.

David is the Global Chief Medical Officer at Microsoft and has a front row insider’s view on how AI is changing healthcare. He believes strongly that our understanding today of AI’s greatest use cases in healthcare don’t even begin to scratch the surface. From agentic AI and ambient documentation to diagnostic reasoning, digital twins, and population screening, there wasn't a hot topic that he didn’t cover with our co-founder Dr. Graham Walker.

Together, they break down:

🤖 Why the future of AI is agentic and collaborative, not all-knowing.
📋 How ambient documentation is restoring physician attention, not just productivity.
🩺 Why most AI tools fail when they ignore real workflows.
📊 How AI can triage, screen, and allocate resources more effectively — before patients ever walk into the clinic.
🧠 And why the most important skill in 2030 for physicians may be knowing how to apply AI responsibly.

👀 Don’t miss this masterclass in what the future of clinical care might look like, from the person who is actively helping to shape it.
