“ChatGPT, MD”: Author Says AI-Empowered Patients, Doctors Take Control

The U.S. healthcare system could save up to 500,000 lives and $1.5 trillion a year by embracing the right technology, says Dr. Robert Pearl, a Stanford University professor and a noted healthcare influencer.

Pearl, who co-authored his new book “ChatGPT, MD” with the help of generative AI, says the tech’s strength lies in its access to the entirety of medical knowledge. “We shouldn't think of [generative AI] as just another AI tool. This is as … different from what's come before as the iPhone was from the telephone that was in most people's kitchens attached to the wall.”

For clinicians and patients alike, that access can be transformative. Parents might use it to uncover what’s wrong with their child when traditional medicine is still searching for answers. A doctor might identify rare diagnoses in minutes, work that would have taken days in a library.

Hospitals already collect massive data — about a terabyte per facility annually — but 97% of it is never reviewed, Pearl says. The key is narrowing it to specific diseases or trends.

Pearl tells “Conversations on Health Care” hosts Mark Masselli and Margaret Flinter that Gen AI will gain widespread medical acceptance when studies compare outcomes with and without the technology

“We're going to find that the technology is 10% better than the average clinician … or the average nurse in a chronic disease management program…or, for that matter, potentially even the average physician doing inpatient care when there are five or six different doctors taking care of the same patient and they're not effectively communicating.”

Self-healing joints? Perfect surgeries? Your tax $$ could make it happen

The director of the Advanced Research Projects Agency for Health (ARPA-H) knows the eyes of the nation are on her. Renee Wegrzyn, Ph.D., leads the billion-dollar effort charged with leveraging research advances for real-world impact.

Wegrzyn talked with hosts Mark Masselli and Margaret Flinter at Aspen Ideas: Health about the agency’s initiatives, including a $100 million sprint for women’s health and creating tissue-specific delivery of therapies.

“How can we pursue some of these breakthroughs — in our case, for health — by empowering the scientists…the program managers…that have these really big ideas that are so risky that the technical sector, the private sector can’t address because there’s no proof of concept?”

She explained the process: Hire program managers with big ideas in health and give them a time frame to find solutions.

Wegrzyn said the time limit ensures they bring a sense of urgency to solving problems. In return, participants get resources to focus on technical risks.

Many of ARPA-H’s missions are cancer-centered, aimed at issues through what-if questions such as: “What if cancer surgeries were one-and-done?” “What if clinical trials evolved in the same way tumors do?”

She said, “The investments that we’ve made in cancer [include] our precision surgical interventions program. Think about reimagining the operating room suites, when a surgeon is looking into a surgical cavity and trying to remove a tumor.”
