At the annual meeting of the Society for Pediatric Dermatology, Zayna Khayat, PhD, said that the future of medicine is driven by six shifts pulling society from a past oriented around the health care system – the buildings, clinicians, and payers – to a patient-oriented perspective. “That doesn’t just happen on its own,” said Dr. Khayat, a future strategist at Toronto-based SE Health. “There are big forces that are pulling us to the future whether we want it to or not. One is that patients have woken up. They have grown to have power in many other complex decisions in their life, and they’re expecting no less from our health care system.”
During her presentation, she discussed the six shifts:
1. The timing of service placement. The traditional model of medicine is “an intermittent and interventional science that waits for the symptoms and goes in and either fixes or manages them,” she said. “So, it’s not really health care; it’s sick care. That’s been fine in the industrial era when we needed to get medicine to stop catastrophic events. Not only is it shifting to be proactive and preventative but it’s shifting to a new science of medicine called predictive medicine.”
As for proactive and preventative care, she continued, each patient’s choice of behaviors related to diet, exercise, and stress “mingles with DNA to produce health, yet we spend about 90% of our resources on sick care. Now, health systems are moving their resources to things like education, housing, transportation, food security, equity, and racial divides. ... This is trickling down to how we train health care professionals. We know that patients live very little of their time in formal care settings, so all of their health is created – or destroyed – well outside of the clinical setting. We train our health professionals mostly in a clinical setting. Health systems are now starting to reimagine how training happens so we can train people to understand the fully loaded context of their patients’ lives.”
2. A shift in precision. For all its advances and science breakthroughs, medicine “is still quite crude,” said Dr. Khayat, who is also an adjunct professor in the Rotman School of Management at the University of Toronto. “It’s very analog, based on a one-size-fits-all approach. In the business world, we call this a segment of one: the idea that in some clinical trial, a result was produced that was based on the average of everybody, and therefore we just give everybody what worked for the average. ... We don’t need to have that trade-off anymore, because it won’t be a trade-off of higher cost to tailor down to an N of 1. It will be highly personalized, intelligent medicine, very precise.”
3. A shift from institution-centered to person-centered care. “The artifacts that health care was built on are very analog and are going to get decentralized out of buildings, dephysicalized, disintermediated,” she predicted. “We’ll have a seamless digital physical experience, expanded channels through which patients can access their services. Pick a channel that makes sense for the patient and don’t let care follow the place but rather let care follow the person.”
4. A shift in care duration, from episodic and intermittent care to more continuous care. “With very little input you should know what’s going on at any point in time instead of time-sharing access to diagnostics and to clinicians,” Dr. Khayat said. Wrist-worn devices that gather personal omics “are now really democratized, with every aspect of a diagnostic clinic available within or connected to a smartphone. This allows for data to be gathered and shared with clinicians, including tools under the skin that can get some of the biochemical data in real time instead of poking and prodding and waiting for a diagnostic lab.” These devices, she said, will become easier to use, cheaper, and will work faster, and provide much better data “at almost zero cost.”
Technologies being developed include tattoos that can read biomarkers, innovations in clothing that can detect biochemical reactions in the skin, underwear that can read vital signs, and contact lenses that can measure glucose levels. “The skin will become a major noninvasive way to obtain information,” she said.
5. A shift in power from providers to patients. “It’s estimated that about 80% of health care decisions could be self-managed by people in their communities,” Dr. Khayat said.
6. A shift from volume-based to value-based care. “Because we’ve been obsessed with the system, we’ve paid for stuff like visits, pills, MRI scans, et cetera,” she said. “We don’t need to do that anymore. Health systems don’t want to keep paying for stuff if they don’t see the results. Because of all the other shifts, we can pay for results. Some call this value-based care. I call it fee-for-health.”
She noted that the future of medicine is underpinned by innovations in AI/predictalytics, voice recognition, virtual reality, blockchain, IoT sensors, 3D printing, omics, robotics, autonomous transport, neurotechnology, nanobiology, and cellular therapy. “They’re moving at a very fast pace because they don’t need the kind of cost, capital, and expertise that the previous tools did,” she said. “This is the promise that technology can bring.”
Dr. Khayat disclosed that she has been a workshop participant for Roche Canada.
