In this episode, Dr. Ed Lee, Chief Medical Officer at Nabla, shares how AI is moving beyond hype to reshape real-world care delivery. Drawing on his experience at Kaiser Permanente, he emphasizes that the true goal of technology is not efficiency alone, but restoring the human connection in healthcare.
Dr. Lee explores why change management, not the technology itself, is the hardest part of AI adoption, and why clinician involvement from day one is non-negotiable. He challenges the early narrative around time savings, arguing that the deeper ROI of ambient AI lies in reducing cognitive burden, restoring joy in medicine, and rebuilding the patient-physician relationship. He also looks ahead to the next frontier: clinical decision support, diagnosis capture, and chart summarization woven seamlessly into workflows. Dr. Lee’s closing thought is simple but powerful – done right, AI shouldn’t feel technical. It should feel human. Take a listen.
This guest appearance was facilitated through conversations initiated at HIMSS.

Ritu: Hi everyone, a very warm welcome to our listeners for Season Seven of the Big Unlock Podcast. My name is Ritu and I’m the co-host of the podcast. We are very excited to have with us today Dr. Ed Lee. Dr. Ed Lee is a physician and healthcare executive leading clinical innovation at Nala, where he focuses on bringing AI into real-world care delivery. He was with Kaiser Permanente for a long time, and we have some very good questions about that for you today, Dr. Lee. At Nala, he’s working at the forefront of ambient AI and clinical co-pilots, helping translate cutting-edge models into tools that actually work in everyday workflows. With that introduction, welcome once again to the podcast, Dr. Lee.
Dr. Lee: Hey Ritu, thank you so much for having me. I appreciate it and I’m looking forward to the conversation.
Ritu: Thank you for being our guest today — really excited to ask you some interesting questions. Let’s get started. We all know that Kaiser Permanente operates as a fully integrated system: payer, provider, and care delivery. How did that structure shape your perspective on what good looks like in clinical workflows, and how did it influence your thinking when you were building tools at Nala?
Dr. Lee: I thoroughly enjoyed my time at Kaiser Permanente. That’s where I actually learned how to be a real practicing clinician — seeing patients, having a large panel of patients to take care of over decades. It taught me how important it is to use technologies that allow clinicians to focus on their patients. At the end of the day, what we want to do is deliver high-quality, personalized care, and quite often technology can get in the way of that unintentionally. What we want to do now, with that understanding, is build technologies that bring the human side of care back to healthcare — removing the friction that technology may have introduced between patients and clinicians, decreasing the administrative burdens that clinicians face, and really making patients the forefront of what we do every day.
Ritu: Great answer. That leads directly into my next question. From all your time at Permanente, what did you learn about the human side of adoption? Because that’s what we’ve been hearing from most of our guests recently — driving clinicians to change behavior versus resisting change, even when the technology is objectively better. AI is passing all these tests, beating doctors on benchmarks, and yet behavioral change is really hard. How did you grapple with that?
Dr. Lee: One of the things I always mention is change management. The change management piece is often the hardest part of implementing new technologies — it’s not the technology itself. The technology can often speak for itself. But making sure clinicians understand the why is critical. Clinicians are very scientific and results-driven; they’re looking for evidence about why things should be done. If you don’t come in with that mindset, and if you don’t involve clinicians from the very beginning of a new technology project, you’re often destined to fail. AI has been around for a short time relative to the grand scheme of how technology has been implemented in medicine, but the impacts are starting to be quite evident. You mentioned how AI can sometimes answer test questions better than human physicians and clinicians. But I still feel the AI out there is really there to augment the clinician and the experience clinicians have with their patients — not to replace them. It’s still up to the clinician to incorporate the information AI brings into the conversation. That human-in-the-loop component always needs to be there to make sure we’re doing the right thing for our patients.
Ritu: That was the conversation we were having six months to a year ago. But now, as we’re seeing more and more co-pilots doing more — going beyond drafting notes and actually suggesting clinical context — how do you maintain clinician trust and ensure that judgment isn’t subtly being outsourced to the system because it’s just so easy? Even in our world of writing code, we’re seeing how easy it becomes to just sit back and let the AI keep generating. The more you engage with it, the easier it gets to let it handle everything. What are your thoughts on that?
Dr. Lee: The easy thing isn’t necessarily always the right thing. What we see with AI-generated outputs is that sometimes they can be very convincing. I’ve done it myself — I’ve plugged things into ChatGPT and it sounds so well-written that it feels like it has to be the truth. But we know that current LLMs are essentially word prediction models generating text, and while they are quite often correct and often bring new insights into the way I’m thinking about clinical scenarios, what you get is based on what you put in. It often requires a clinician’s expertise to put in the right prompt and bring in all the right factors to get the right output back. That’s where I have some concerns about these tools being available to all patients directly — they may not understand all the factors that need to go into the system to get the right output. And without clinician expertise to filter, interpret, and apply it to a real-world scenario, you may run into situations where the output sounds very convincing but isn’t exactly what you need because of what went into it.
Ritu: Are you seeing that a lot? We’d love to hear about it in the context of Nala. A lot of the narrative around Nala’s tools focuses on saving physician time. But what are some of the less obvious yet most strategic forms of ROI that health systems should be paying attention to? As you’re saying — if easy isn’t always right, you can’t just focus on whether ambient is saving the physician eight minutes or sixteen minutes. What are some of the other metrics we should be looking at?
Dr. Lee: It’s a great question. Early on, physicians were reporting saving an hour or even a couple of hours a day, and that’s what the data was showing at the time. Since then, multiple studies have come out showing that the time savings per encounter is actually smaller than that, and some clinicians aren’t necessarily having less after-hours time. I think it varies from clinician to clinician — some are saving an hour a day, cutting into the pajama time they would otherwise be doing. But what I’ve found myself in using Nala and other ambient and AI tools is that it gives me agency. What I mean is that I’m now able to budget my time the way I want to in the care of my patients. I could rush through my day, compact it more using the AI tools available and finish early — or I could invest the time I want to invest in my patients and develop those relationships and be more thoughtful about the care I deliver. So the time I could be saving in the global context of patient care time could be more, but I choose to invest that time into developing relationships with my patients. One of the ROI points that was talked about in the past was time savings, but now a lot of the conversation has shifted toward cognitive load, cognitive burden, and the joy and meaning that clinicians can get from using these tools that they otherwise would not have. Burnout has been shown to decrease because of these tools, and it’s not necessarily related to time saved. It’s because clinicians are now doing what they went into medicine to do in the first place — not working on a computer or acting as a transcriptionist, but being a caregiver, a clinician, a scientist, bringing in evidence and applying that knowledge to improve the lives of the patients they work with. That’s where I see some of the biggest gains from using this type of technology.
Ritu: That’s a great answer and it allows us to unpack a lot more. I remember reading somewhere that because of ambient, doctors are actually articulating more — because they know that whatever they say is going to be registered. Because of that, patient satisfaction increases because patients feel the physician is being more communicative. So it’s not just about the time spent, but actually increasing communication with the patient and resulting in a more meaningful interaction.
Dr. Lee: It’s a really insightful observation, because it may not have been one of the things we expected when we first deployed this type of technology. But as time has gone on and experience has been gained, it really is a win-win situation. Patients do feel more engaged in the conversation and get more explanation from the clinician — and it’s sort of a byproduct of the clinician wanting the ambient technology to hear what they’re saying so it gets captured in the note. They don’t have to write it later, but the patients gain almost as much as the clinicians do through the process of making the technology work for both sides.
Ritu: Exactly. So that leads into the next question: if ambient is just the first layer, what does the next phase of AI co-pilots in healthcare look like, and how far are we from that reality?
Dr. Lee: Next steps are happening right now, even as we speak. You mentioned ROI earlier, and I think there are different ways of looking at it. There are the human factors and softer components — decreased burnout, increased retention, recruiting strong clinicians who are looking for organizations that have this technology ready and deployable. But also looking at diagnosis capture and coding, making sure those financial components — which are critically important within the healthcare system — can be captured accurately and justifiably. Accurate documentation is very supportive of those goals, and surfacing the right diagnoses, CPT codes, and ICD-10 codes are things that are happening now and continuing to be built up. Beyond that, chart summarization is being incorporated into documentation to make it more complete. There’s so much in a patient’s chart — sometimes decades of information — and being able to distill it down and surface the key points pertinent to the conditions being addressed, so the clinician can see that at the point of care, is happening now. Then transitioning that into clinical decision support — and I think that’s something clinicians would really be enthusiastic about adopting, as long as the trust factor is there. What I mean by clinical decision support is having AI surface potential diagnoses, treatment options, diagnostic tests, and orders at the point of care — or even before or after — and having all that happen seamlessly throughout the entire process: seeing the patient, documenting, entering orders, and surfacing clinical information that allows the best care to occur.
Ritu: That captures what I was going to ask next. In one of your earlier answers you mentioned friction, and I wanted to ask: in real clinical settings, where do you think AI still falls short, and what needs to happen for it to become truly invisible infrastructure? I think you’ve kind of answered that — to be truly invisible, it has to do more than just the ambient piece and get into all these other areas you’ve described.
Dr. Lee: I think it does, and the word friction is almost visceral to me — it’s just things that get in the way of what you really want to get done. The clinician’s goal is to provide the best care for the patient, but things have been introduced into the system between the patient and the physician over time through technology that technology can actually help remove. Some of the tools being developed now are amazing, but if something isn’t built into the workflow — if it adds five extra clicks per patient — clinicians just aren’t going to use it. So it’s not only what a tool can do, it’s how it does it and how it’s incorporated. It really needs to be thoughtful in terms of usability so that clinicians can actually adopt it. You can put a tool out there, but as the saying goes, hope is not a strategy. The strategy should really be around understanding the needs of the clinician and their workflows, and building tools into those workflows so that the technology is truly seamless and can be adopted and scaled easily. I talked about the change management piece earlier — it all comes back to that.
Ritu: Thank you, Dr. Lee. Throughout these questions we’ve gotten your perspective as a clinician, but we also like to ask about your origin story on the podcast — how you got into healthcare, how you got into this intersection of technology and healthcare, and how you came to understand both sides. Our listeners would love to hear more about that.
Dr. Lee: Thanks for asking. Early on in my childhood I thought I wanted to be a doctor. I had older siblings who went into medicine and I saw the gratification and satisfaction they had in their work, so it was an easy path for me when I was thinking about the intersection of science, healthcare, and being able to help patients. That’s how I first got into medicine. I actually thought I was going to be purely a clinician my entire career — that’s what I went into medical school and residency thinking I would do. But along the way, I was fortunate to have mentors who allowed me to think beyond that and exercise my interests outside of direct clinical care. I was always interested in doing things more efficiently using technology and incorporating that into the practice of medicine. Early on in my career at Kaiser Permanente, I was fortunate to be involved with different technology products and projects that led me down a path where I saw the magnitude of how technology could affect healthcare in the present and into the future. When the AI boom happened, I saw that magnified significantly, and that’s why I decided to embark on my work with Nala — an innovative, agile company really improving the lives of clinicians using these tools. I wanted to bring this type of technology to all clinicians because the burden of clerical and administrative tasks hinders our ability to provide the best care possible. If we can have technologies like Nala and other AI-powered tools, I think the healthcare system can not only improve how we deliver care and the quality of care, but also the cost of care — because we’ll be providing care that is more proactive and less reactive, which is better for patients and economically better in the end as well.
Ritu: Thank you for sharing that, Dr. Lee. That’s always very inspiring for our listeners. What you talked about — proactive versus reactive — we’ve been hearing a lot, especially in the context of wearables and the constant stream of information coming in that’s going to change the nature of doctor’s visits. People are already uploading their entire blood reports to ChatGPT and other AI platforms and wanting answers. Medicine is going to change very quickly. We’re almost at the end — it’s always great to hear your insights. Any closing remarks or advice you would have for our listeners, and what are your predictions for the next one to three years?
Dr. Lee: I thoroughly enjoyed the conversation — thank you. As I think about it, at the end of the day AI is just technology. I don’t mean “just” to diminish it, but it is technology, and I’ve always believed that technology in healthcare is really there to improve how we care for our patients. If we do this right, it shouldn’t feel technical — it should feel more human. It should give clinicians time, attention, and presence back. And I think that’s what patients remember, and what clinicians remember as well. At its best, healthcare is human, and I think AI should help us get back there.
Ritu: Great answer. Thank you so much, Dr. Lee. We really enjoyed our conversation. Thank you for being our guest.
Dr. Lee: Thanks so much, Ritu. Appreciate it.
