Ambient artificial intelligence (AI) scribes have become the fastest-adopted physician technology in recent memory. At UCSF, 70% of physicians now use one daily. At Kaiser Permanente, more than 7,000 physicians used them across 2.5 million patient encounters in just over a year. But what does the evidence actually show, and what are practices getting wrong?

In this feature episode of Off the Chart, Medical Economics Associate Editor Austin Littrell goes deeper on the AI scribe era, alongside Medical Economics' March-April 2026 cover story: Take note: The AI scribe era is here.

Robert Wachter, M.D., chair of the Department of Medicine at UCSF and author of "A Giant Leap: How AI Is Transforming Healthcare and What That Means for Our Future," is our main guide — explaining why documentation was the right entry point for AI in medicine, why the efficiency gains have been overstated, and why he's worried about what happens at note number 50.

We also hear from Shannon Sims, M.D., Ph.D., FAMIA, of Vizient on the case for thinking beyond the 12-month P&L, Marc Succi, M.D., of Mass General Brigham on where AI clinical reasoning actually stands today, and health care attorney Dan Silverboard, J.D., of Holland & Knight on the legal risks practices can't afford to ignore.
