Building With AI

How to Build AI Tools That Doctors Actually Use | Dr. Graham Walker (Founder of Offcall and MDCalc)

Episode Notes

Dr. Graham Walker is an Emergency Physician and the Founder of MDCalc, a clinical decision support tool used by over 70% of U.S. physicians. He also co-founded Offcall, a platform addressing physician burnout through transparency and data-driven insights.

We dive deep into the real-world use cases of AI in hospitals—from predictive models that detect patient deterioration to generative AI scribes that free doctors from paperwork.

In this conversation, we discuss:

• How MDCalc became a must-have tool for 70% of U.S. doctors,
• Impact of AI scribes on physician burnout and patient care,
• Risks of overreliance on AI,
• Barriers to AI adoption in hospitals (privacy, cost, and trust),
• The AI-powered emergency room of the future,
• And much more!
