ECG’s radio show and podcast, Healthcare Upside/Down, offers unfiltered perspectives on what’s working in US healthcare and what’s not. Hosted by ECG principal Dr. Nick van Terheyden, each episode features guest panelists who explore the upsides and downsides of healthcare in the US—and how to make the system work for everyone.

The “Oxford Handbook of Clinical Medicine” was a godsend to junior doctors and experienced physicians alike. First published in 1985, it came in a pocket size—small enough to fit into the white coat of every doctor, crammed in next to the various other essentials we had to carry around.

The book was a great companion covering a wide range of topics in a succinct style. But like so many innovations, it received mixed responses at the time—including being banned by some medical schools for making medicine too easy.

Today we’re seeing something similar with ChatGPT. For some, the artificial intelligence (AI) chatbot is a great gizmo that is ready to provide useful information and serve as a tool in our quest for knowledge—and in this case, help improve the delivery of healthcare. To others, it’s something to be feared, controlled, and even banned.

Let’s be clear—ChatGPT is not replacing humans anytime soon (at least not in the opinion of this host). But it is offering some major opportunities and leaps to our world, and certainly in some as yet undefined or untried ways.

Harvey Castro, MD, MBA, is an emergency physician and the author of the book “ChatGPT and Healthcare: The Key to the New Future of Medicine.” On the final installment of our series on ChatGPT, he explains how he’s incorporated the tool into almost everything he does—and how it can change the way providers care for and communicate with patients. Below are a few excerpts.

Advocating for AI.

“I feel like [ChatGPT] is a great assistant. I use it for brainstorming sessions. But the downside is that at the beginning, you don’t know what you don’t know. The more I used it, I started realizing certain answers it was making up didn’t quite sound correct. I have an MD and an MBA, and tons of experience in business. And I thought, there will be people asking a question who don’t have the background to know the answer is incorrect. So I thought, why not be in front of this technology? Why not advocate for it, explain the pros and cons, and just teach people? And that’s what I’ve been doing on social media [and in my] book.”
