Editorial
I've spent years observing the shifts in healthcare, and the rise of AI stands out as a particularly impactful development.
We often hear the term "AGI," but it's a broad concept that needs clarification. That's why I want to share my professional perspective on five different levels of AI — including each level’s distinct capabilities — and what they could mean for all of us in the healthcare sector.
Level One: The Chatbot Era
At its most basic level, AI manifests as chatbots. These systems, while helpful for routine interactions, are not particularly sophisticated. They can provide simple answers, schedule appointments or direct patients to relevant information. Think of them as the first step toward automated patient care; we can all relate to them.
Example: A hospital system introduces a chatbot on its website. It fields basic questions about hospital hours, services offered and where to find specific departments. This frees up staff to focus on complex patient needs and provides patients with quick answers to their basic questions.

Level Two: Reasoning Capabilities
This level represents a substantial leap forward. Here, AI systems start showing the ability to reason. We’re not just talking about answering pre-programmed questions; these systems can process complex information, identify patterns and make deductions. Sam Altman, one of the founders of OpenAI, thinks we've already reached this point. This capability could drastically change diagnostics and treatment planning.
Example: An AI tool analyzes a patient’s medical history, including lab results and imaging scans, to predict the likelihood of developing a specific disease or even propose an alternative treatment plan based on similar cases in a database. This tool provides a second opinion or offers a data-driven perspective on treatment choices. I have seen this with some of the latest AI platforms in development to improve diagnostic accuracy, and it is very impressive.
Level Three: Collaborative Agents
In level three, AI starts to function as a partner. These systems don't just work alone; they can collaborate with human professionals, taking on complex tasks and working together toward a common goal. I am very excited about this level, as it can truly be a revolution in the healthcare sector, working alongside us. Sam Altman predicts this stage will be reached sooner than we expect, and I agree.
Example: An AI agent can assist in surgery by providing real-time analysis of scans and images, guiding surgeons with precision and predicting potential complications as the procedure progresses. It can also help manage patient care plans by automatically updating records, coordinating schedules and proactively sending reminders for medication or appointments. This will allow us to allocate our resources better and improve our productivity so that we can focus on more complex cases that require our direct human intervention.
Level Four: The Innovators
This is where things get very interesting. Level four AI can do something we, as professionals, appreciate: it can explore and understand new phenomena. These systems move beyond their initial programming to develop new solutions and discover new areas for advancement. Think of these systems as the researchers of the AI world, constantly pushing the boundaries of what’s possible. I see this level as a partner in developing more complex and better treatments.
Example: An AI program scans all the medical literature available and identifies a new connection between a specific gene expression and a rare disease. It proposes a new treatment avenue based on research we were previously unaware of and creates an opportunity for researchers to explore further. This kind of innovation has the potential to alter how we approach medicine and healthcare development.

Level Five: Scaled Innovation
At the final level, we start to see AI's widespread impact on an organization. Level five AI drives large-scale innovation within organizations, revolutionizing how things work at a systemic level. In our world, this can mean better healthcare systems.
Example: An entire hospital system uses AI to streamline resource allocation, improve patient flow and proactively identify areas for improvement. The system also personalizes treatment plans, monitors outcomes, predicts demand, improves patient care, reduces hospital costs and optimizes processes. This kind of change can really improve the way we operate and provide better healthcare.
Shaping AI’s Future in Healthcare
My perspective is clear: understanding these different levels of AI will allow us to better navigate its impact on our work. We need to get involved, learn and collaborate, because this is not the future; it is now. We, as professionals, must be the ones guiding the integration of AI into healthcare. This is our chance to shape a better future for our patients and ourselves. Let’s not stand by; instead, let’s proactively participate in this transformation.
The journey through AI's different levels is more than just a technical one; it’s about how we reimagine healthcare. From basic chatbots to collaborative agents and innovative systems, AI has the potential to change our industry profoundly. But it’s up to us, as healthcare professionals, to guide this development, learn, collaborate and ensure that AI helps us provide better, more efficient and more equitable care.
