"I think we're going to get better and better for the right tool at the right time."

AI in Medicine: Applications and FDA Approvals [04:40]

• AI tools are categorized into three main areas: rule-based tasks, FDA-approved diagnostic tools, and generative AI for creative applications.
• Rule-based applications include managing drug-drug interactions and risk scoring for pre-surgical testing.
• Approximately 220 AI tools have been approved by the FDA, primarily in cardiology and radiology, with examples like triaging diabetic patients based on fundus images.
• Generative AI is accelerating progress in broad biology understanding (e.g., protein function) and new drug development, as well as in patient communication.

The discussion outlines the current landscape of AI in medicine, from established rule-based systems to emerging generative tools, showcasing their increasing integration and regulatory acceptance.

"The places where you're starting to see the most acceleration with more of the generative tools are actually on two very different ends of the spectrum."

The Agent Space and Workflow Integration [06:45]

• There's a desire for a single AI "agent" that can understand user intent and leverage various specialized applications as tools.
• This concept aims to avoid the need for users to interact with multiple interfaces or applications for different AI functions.
• Tools that are embedded directly into daily workflows, like scribe technology, see higher adoption and acceptance.

This section explores the potential for AI agents to simplify user interaction and highlights the critical role of workflow integration for successful AI tool deployment.

"Do you have to have five different UIs? Do you have to have a bunch of tools on your desktop or are we now again to catch another buzzword the agent space where I have a model that understands my intent well enough that I can just talk to one model?"

Consumerization of Healthcare with AI and Wearables [11:09]

• The consumer push for AI in healthcare is echoed in policy initiatives like those related to wearables and data interoperability.
• The vision is to place the individual at the center of their healthcare journey, with AI tools following them throughout their lives.
• An example is managing cardio-metabolic disease, where continuous glucose monitors provide personalized insights and empower individuals to make informed choices with the help of generative AI.

This segment delves into the potential of AI and connected technologies to empower individuals in managing their health, moving towards a more personalized and continuous care model.

"If you want to be really simple with a lot of the work that we're doing with AI and beyond, what information do we have and how can we make a difference and make an action?"

Longitudinal Data and Blending Consumer/Clinical AI [14:17]

• Current healthcare models often focus on episodic care, lacking visibility into the patient's health between visits.
• There's a growing trend of consumers using consumer-facing AI models to discuss their health data and decisions, sometimes leading to different diagnoses than those provided by healthcare professionals.
• The challenge is to bridge the gap between consumer AI insights and clinical care, ensuring that this richer, more granular data can be used to provide better patient care.

This part addresses the challenge of integrating fragmented health data, particularly the insights gained from consumer AI use, into a cohesive and actionable clinical care plan.

"Is there a place where these start to blend together? I mean, we've learned from the data like like the work that you've done that having that other information that more granularly we can take better care of our patients. How do we bring these together?"

AI as an "Action Agent" in Healthcare [17:39]

• A significant portion of AI queries (5-10%) are health-related, indicating strong public interest.
• AI has the potential to act as an "action agent," transforming the healthcare system into one where professionals leverage AI-generated information to make informed decisions, similar to how medical devices are trusted today.
• The key is ensuring that AI-generated information is safe, effective, valuable, and actionable, allowing healthcare professionals to act upon it confidently.
