Generative AI and Precision Medicine – The Future is Not What It Used to Be

“When we look back in (the year) 2041, we will likely see healthcare as the industry most transformed by AI." 

                                                                                                                                           - Kai-Fu Lee, AI 2041


Generative AI is a new and rapidly emerging form of artificial intelligence that has the potential to revolutionize precision medicine by improving diagnosis, treatment, and drug discovery. It’s comprised of Large Language Models and other intelligent systems that replicate a human's ability to create text, images, music, video, computer code, and more.


So, naturally, when Damian Doherty, Editor-in-Chief of Inside Precision Medicine, approached me last fall about writing an article on Generative AI, the first thing I did was ask the latest version of ChatGPT to provide a 2,800-word manuscript on the opportunities and issues of its application to precision medicine.


The content it generated was relevant, logically organized, and backed up with factual information. Sentence structures were precise and delivered in an easy-to-understand format. There was a formulaic beginning, middle, and end, with the correct provisos stated for being wrong.

The result was quite good, but in the end, it was a little too GPT-ish. There were many things my human brain wanted to know that it didn’t cover or guide me towards.


In some ways, this exercise mirrors the deeper discussions and explorations that are just getting underway to both understand our new and evolving AI capabilities and define a logical pathway to help clinicians and researchers make the practice of medicine more precise.

I’ve had the benefit of working with the application of AI in health and medicine for over a decade. Here are my very human thoughts on what should be considered as we approach this opportunity.


An AI Taxonomy


Generative AI is a relatively new form of AI that has been released into the wild. As such, there are very few experts. This means that we are all early in the journey of understanding what it is and how we apply it to do good.

The chart below provides a simple taxonomy to help differentiate generative AI from other forms of Predictive Analytics.

While there is a great deal of hype over generative AI, there is a growing body of evidence on the things it can do well with humans in the loop:[i]

•       Write clinical notes in standard formats such as SOAP (subjective, objective assessment and plan)

•       Assign medical codes such as CPT and ICD-10

•       Generate plausible and evidence-based hypotheses

•       Interpret complex laboratory results

Going forward generative AI will provide benefits in many areas including:


Drug Discovery and Development: Assistance in the discovery of new drugs and their development by predicting molecular structures, simulating drug interactions, and identifying potential drug candidates more quickly and accurately. AI can identify existing drugs that could be repurposed for new therapeutic uses, potentially speeding up the drug development process and reducing costs.


Personalized Treatment Plans: Analyze large-scale patient data, including genetic information, medical records, and imaging data, to guide physicians in the creation of personalized treatment plans tailored to an individual's unique genetic makeup and health profile.


Disease Diagnosis: Assistance in the early and accurate diagnosis of diseases by analyzing medical images, genomic data, and clinical records, helping healthcare professionals make more informed decisions.

 

Medicine has Been Here Before – Change is Hard


Since medicine came out of the shadows and into the light as a data-driven, scientific discipline we’ve always aspired to be better. The reality is that change is hard. It requires us to think and act differently.


When cholera was raging through London in the 1850’s Dr. John Snow was initially rebuffed when he challenged the medical establishment by gathering and presenting data demonstrating that the root cause of cholera was polluted water rather than the prevailing view that it was caused by bad air. From this came the early stages of epidemiology.[ii]

 

In the 1970’s the introduction of endoscopy into surgical practice was met with resistance in the surgical community which saw little use for “key-hole” surgery as the prevailing view and practice was that large problems required large incisions. Today, the laparoscopic revolution is seen as one of the biggest breakthroughs in contemporary medical history.[iii]

 

Generative AI and Large Language Models are part of medicine’s next frontier. They are already challenging current practices across the spectrum of research, clinical trials, medical and nursing school curricula, and the front-line practice of medicine. It’s not a matter of whether it will affect what you do but rather how and when.

 

With the right dialogue and guidance from a diverse set of stakeholders, we will create a path forward that leverages the benefits of our evolving creations to improve health and medical practices while ensuring that appropriate guardrails are put in place to monitor and guide its use.

 

It’s Not About Going Slow. It’s About Getting Things Right


In some ways, the challenge of generative AI today is less about increased AI capabilities and more about the velocity of change it is driving.

Generative AI came screaming into mainstream consciousness in the fall of 2022. ChatGPT, a generative AI product from OpenAI, racked up 100 million users in two months. In the history of humans, there has never been a product that has seen such rapid adoption. Shortly after ChatGPT reached this milestone the next version of GPT was released with greatly increased capabilities.


From the practice of medicine to the development of new drugs, generative AI’s “speed of progress” is not following the normal path that economists refer to as linear growth.  This is where something new is created that adds incremental value, which then creates a small gap between the time of its creation and when it starts being used. As adoption occurs there is another small gap between uptake and the time it takes for policymakers to develop necessary guard rails to both guide its use and safeguard users from risks. Linear growth is steady and predictable and what clinical and operational systems are set up to manage.


Generative AI is upending linear growth. It’s taking a different trajectory that economists call exponential growth. This is where something increases faster as it gets bigger. Most of our systems are not designed to accommodate this dramatic escalation in change. Exponential growth doesn’t last and eventually, the pace of change returns to linear growth. But when it’s happening it feels like the world is inside a tornado.

The European Parliament approved landmark rules for artificial intelligence, known as the EU AI Act which aims to bring generative AI tools under greater restrictions. This includes generative AI developers being required to submit these systems for review before releasing them commercially.[iv]Here in the United States the Biden administration issued an Executive Order last fall to build momentum within federal agencies and the private sector to put better guardrails in place for the use of AI.


The rapid change driven by generative AI has some calling for measures to slow or even suspend AI development to evaluate its impact on humans and society. A petition from the Future of Life Institute was put forward and signed by leaders including Elon Musk calling for a six-month moratorium on AI development.[v]

 

While there is uncertainty in what we are creating and how it should be applied, it is unlikely that any mandates will slow the pace of AI innovation.


Instead of attempting to slow progress, let us expedite the education and dialogue among policymakers, medical and research leaders, and frontline practitioners to chart a course for progress in applying our new intelligent capabilities. These groups are also most relevant to ensuring that a necessary set of laws, regulations, and protocols are in place to safeguard those both providing and receiving health and medical services.


The Creation of Enforceable Responsible AI Principles


Let’s recognize and support the overall good that can come from AI innovation. At the same time, we must be mindful of how our ever-expanding AI capabilities can replicate and even amplify human biases and risks that work against the goal of improving the health and well-being of all citizens.


Prioritizing fairness and inclusion in AI systems is a socio-technical challenge. The speed of progress is spawning a new set of issues for governments and regulators. It’s also challenging us with new ethical considerations in the fields of medical and computer science. Ultimately the question is not only what AI can do, but rather, what AI should do.


While legislators and regulators work on finding common ground, health and medical organizations using AI today should have a defined set of Responsible AI principles in place to guide the development and use of intelligent solutions. Most often, these principles or guidelines are reviewed and approved at the highest level of leadership and incorporated into an organization’s overall approach to Data Governance.


AI in Medicine is Not About Technology. It’s About Empowerment


AI has a PR problem. The narrative in the popular press and professional journals is often negative.  Headlines like “Half of U.S. Jobs Could be Eliminate With AI,” paint a picture of a future work world dominated by what novelist Arthur C. Clarke calls robo-sapiens.[vi] [vii]


It’s no wonder that people are worried. According to a study by the American Psychological Association, the potential impacts that AI could have on the workplace and jobs is now one of the top issues impacting the mental health of workers.[viii]


Generative AI is already impacting today’s workplace and will be the single greatest change affecting the Future of Work in the next decade. It will impact how all work is done. As you let that statement sink in, recognize that the issues to be addressed go beyond productivity. After all, work brings shape and meaning to our lives and is not just about a job or income.


In this regard, there is growing evidence to suggest that AI can increase not only productivity but also job satisfaction.


In a randomized trial using generative AI, 453 college-educated professionals were given a series of writing tasks to complete. Half were given support with ChatGPT. The control group was not given access to Chat GPT. The results showed that the time taken to complete tasks was reduced by 40% among those using this form of generative AI. Beyond increased productivity, those using ChatGPT reported an increase in job satisfaction and a greater sense of optimism. Most importantly, inequality between workers decreased.[ix]


Done right, AI is not about technology. It’s about empowerment. Properly curated, generative AI will help solve one of the most significant challenges facing healthcare - The shortage of human capital.


The effective introduction and use of generative AI in health and medicine enables both cost-cutting automation of routine work and value-adding augmentation of human capabilities. As it and other forms of AI become pervasive in health and medicine, a new intelligent health system will emerge. It will facilitate systems that improve health while delivering greater value. It will provide a more personalized experience for consumers and patients. It will liberate clinicians and restore them to be the caregivers they want to be rather than the data entry clerks we’re turning them into by forcing them to use systems and processes conceived decades ago.


And while generative AI is coming at us fast with much to understand in how we use it, it could not have come at a better time.

Egberto Willies is a podcast host and commentator who always tries to tease out the "real story" happening behind the scenes of news today. I had the opportunity to sit with Egberto and talk about why America spends more on health care than any other country, and yet, we as citizens are the least healthy in the developed world and most likely to die early. I covered some of the key issues found in my new book, Health Care Nation. Go here to listen to our wide-ranging conversation on health care and our ability to reimagine a better use of our talented health professionals and resources.

Remember the movie, Jerry Maguire? (Show me the money!). I had dinner last week with Leigh Steinberg…the real Jerry Maguire who was personified in the movie by Tom Cruise. Leigh is a legend in the sports world. Leigh has been one of the greatest advocates in calling attention to the devastating effects of concussions and brain injuries in sports. From the NFL to pee wee sports, Leigh is the guy who drove visibility and protections for athletes everywhere. I had the privilege of being on stage at HIMSS25 with Leigh to talk about his great work and what's ahead for the treatment and prevention of concussions and brain injuries, neuroplasticity, and the future of brain health.

Two weeks ago President Donald Trump made waves in the global health community by issuing an Executive Order to pull America out of the World Health Organization (WHO). Founded in 1948, WHO is an agency of the United Nations whose charter is to plan and coordinate the international response to health emergencies as well as help countries monitor, prepare, and recover from disease threats. While not without controversy, WHO is the most recognized global forum for predicting and planning for events affecting the health of humans across the planet. Media coverage of the US withdrawal has focused on political rancor (Trump believes WHO mishandled the pandemic) and funding (While the US is one of 194 participating countries, it funds almost 20% of the agency’s $6.8 billion budget). [i] As the new Administration gives up America’s seat at the table for global health planning, it's important to shine a light on very real issues impacting the health and well-being of Americans. They are worth public scrutiny and debate starting with this statement: America is a First-World Nation Battling its Own Third-World Health Crises America’s health care system is the most expensive in the world. It’s staffed with some of the world’s best health and medical talent. Despite this, we are at the bottom of the list in overall health compared to all developed nations. This includes access to care, administrative efficiency, equity, and health care outcomes. [ii] Americans are among the least healthy people in the rich world and among the most likely to die early. The richest men in America live longer than the average man in any country. The poorest have life expectancies comparable to men in Sudan and Pakistan . [i] If you are a citizen of Mississippi, you probably won’t live as long as someone from Bangladesh . [ii] [ iii] [iv] Maternal mortality rates for American women are worse than in most third-world countries. Even more unexplainable is that Black women are three times more likely to die of childbirth than White women. This gap is worse today than it was when we began keeping records in the early 1900’s. [i] America is a global leader in avoidable amputations. This is mainly due to the improper management of diabetes, which impacts 38.4 million Americans. [ii] 30 million Americans die prematurely each year from preventable diseases. Twenty-seven percent of US health-care spending goes to managing health conditions that are preventable. [iii] As the World Health Organization focuses on increasing its investments in global Public Health, it’s important to note that America’s investment in similar Public Health services is declining. Winston Churchill once said, “Healthy citizens are the greatest asset any country can have.” And so, as we discuss and debate America’s role in creating a healthier world through organizations like WHO, let us actively debate and decide what priorities we will invest in to improve the health of the 330 million people who call America home.

I’ve been pondering how many journalists and podcasters I’ve ticked off when answering this question: Where will AI be in a year? My answer has always been simple and honest: No one knows. This week the Chinese start-up DeepSeek is the latest shift in AI’s tectonic plates. Seemingly out of nowhere, it became the top-rated AI app in the United States. Deepseek’s new, open-source AI model rivals the abilities of OpenAI's most recent model—with far less investment and using reduced-capacity chips. Training costs for ChatGPT-4 were over $100 million. Deepseek’s investment was supposedly $6 million. Deepseek’s model improves energy efficiency making AI more accessible to more people and industries and could be welcomed news when it comes to AI’s environmental impact. There’s a lot to be learned about Deepseek’s capabilities. For now, it certainly ups the ante in the AI “space race” for global tech titans and governments. I can hear the hype machines starting to churn as I write this. Here’s a solid piece from Scientific American that outlines what is known. And so: Where will AI be in a year? No one knows. T.

I am pleased to announce that I have a new book coming in April: Health Care Nation - The Future is Calling and It's Better Than You Think. Whether a patient, health consumer, physician, nurse, health executive, or elected official, somewhere deep in our brains is this simple truth: the American health system isn’t working, and it will only get worse if we don’t do something about it. Despite spending more money per capita on healthcare than any other country in the world, the U.S. struggles to match other nations in life expectancy, health outcomes and general well-being. Meanwhile, the system spends more on unnecessary, ineffective, and wasteful services than what we collectively invest in K-12 education in America. All the while, our health status is declining. For the first time, kids born today may not live as long as their older siblings. Health Care Nation shines a light on the deep interconnectedness between the health of people and the health of a nation. It’s about the opportunity and responsibility each of us has to reimagine and reengineer a system that focuses on keeping all citizens healthy and caring for them when they are not. Health Care Nation takes readers on a journey to understand the fundamental issues driving the system in the wrong direction. It focuses on helping each reader find or sharpen their voice in what should change based on their views, values and experiences. Health Care Nation awakens readers to the possibilities that exist today that are right in front of us if only we choose to see them. It creates an understanding of the forces at work in healthcare today that are driving us in the wrong direction, instilling readers with a sense of activism that mobilizes them to take action. The ultimate goal of this book is to help everyone find and use their voice to drive positive change. Health Care Nation is designed to help readers understand the role they can play and actions they can take to determine the health and economic well-being for generations to come. My publisher is doing an early book launch at the HIMSS conference in Las Vegas March 3-6. Would love to see you if attending. Look for me at the HIMSS bookstore near the exhibit hall. I'll be signing advance copies. Health Care Nation is also available for preorder on Amazon. For more information about the book go to www.healthcarenation.us . T.

With January comes a sea of predictions for 2025. Many are insightful, but if you're a health leader tracking AI developments, here are three emerging themes to pay attention to. The Great AI Pivot: From FOMO to Value Since the Fall of 2022, AI hasn’t been just a technological shift—it’s been a cultural phenomenon. Conversations about AI spread from the conference room to the dinner table. Organizations adopted it at breakneck speed, and the fear of missing out (FOMO) drove up to 60% of AI’s recent adoption. One study found that 63% of leaders feared their organizations would fall behind if they didn’t join the AI gold rush. In the coming year, forward-thinking leaders will pivot from pursuing limited-value AI applications to investing in ecosystems of people and processes that generate scalable, repeatable value (think innovation flywheel). This is a different mindset compared to the approach taken by many leaders in the last two years. It’s a recognition that AI is here to stay and that creating “value-at-scale” requires the adoption of a growth mindset for what’s ahead.
