Amazon’s One Medical team is reportedly considering developing an AI agent called DoctorAI that would optimize clinician tasks, make product and service recommendations, and manage customer service requests.

In England, NHS trusts are using patient engagement prediction software from Deep Medical to identify patients who are likely to no-show or cancel their appointments with short notice. Volunteers reach out to the patients who are identified by the system three weeks ahead of time to see if they need assistance – such as with transport, translation, or parking fees – and to reschedule their appointments in the event of conflicts. NHS England says that patients don’t show up for 6.4% of its 125 million outpatient appoints each year at a cost of nearly $2 billion.

Research

Researchers find that ChatGPT isn’t good at diagnosing patient conditions. It incorrectly analyzed half of a set of the 150 case challenges it was given, where it struggled with interpreting lab values and imaging results and failed to use complete information that was relevant to the diagnosis. They found that it works well as an educational tool, did a good job with differential diagnosis, and accurately suggested next diagnostic steps.

In England, nine hospital trusts are using Ufonia’s Dora conversational clinical assistant to call patients three weeks after their cataract surgery and alert clinicians if they need further care. Two-thirds patients who undergo cataract surgery, which is performed 500,000 times per year, do not require an in-person appointment. The company is a spin-off of Oxford Unversity.

A pain patient’s op-ed piece expresses skepticism about AI in healthcare:

• Hospitals could have already solved the same patient problems if they really wanted to.
• The real motivation for health systems to use AI is to make more money rather than to lower patient bills.
• AI-drafted responses and emails to patients are easy to spot, and many of the initial patient emails were generated because of inefficient policies, such as requiring patients who have incurable conditions to contact their doctor every month to have their pain medication refill approved.

Research

Healthcare experts who were convened by Stanford University’s Institute for Human-Centered AI say that HIPAA as well as the FDA’s regulatory authority are too outdated to apply to rapid AI development. Specific recommendations:

• Streamline FDA market approval for AI-enhanced diagnostic capability, moving the emphasis to post-market surveillance; sharing test and performance data with providers to help them assess product safety; and creating finer-grained risk categories for medical devices.
• Participants were divided on the issue of requiring clinical AI tools to place a human in the loop, with some warning that such a requirement would create more busywork for doctors and make them feel less clinically empowered. Some said the model should be similar to that of laboratory testing, where devices are overseen by physicians, undergo regular quality checks, and send out-of-range values to humans for review. Participants were also mixed on requiring that patients be informed when AI is used in any stage of their treatment, although many felt that AI-created emails that are sent under a provider’s name should indicate that AI played a role.
• About half of participants said that chatbot-type AI tools should be regulated using medical professional licensure as a model, while a nearly equal number favored a medical device-like approach.

Researchers survey oncologists about their possible use of AI, with these conclusions:

• They will use AI to make clinical decisions only if they as frontline practitioners can understand its logic.
• Most oncologists think that they should protect patients from biased AI tools, but few of them believe that they can recognize that bias.
• More than 90% of oncologists believe that AI developers should be held accountable if their products are involved in medical or legal problems, about double the number who believe that doctors and hospitals should share accountability.
• A medical oncologist predicts that AI tools will be used in three areas: making treatment decisions using a broader set of data, improving tumor characterization from images, and matching patients with clinical trials.

Anesthesiologist, informaticist, and AMA immediate past president Jesse Ehrenfeld, MD, MPH says that the AI in healthcare hype curve is peaking, but he notes that a recent survey of doctors found that 38% are using AI in their practices, almost all of it for back-end office tasks. He says that it was a mistake to design, develop, and deploy EHRs without enough physician involvement, and that same error could be repeated with AI development. He explains, “I see this with entrepreneurial companies, where there’s a physician who might be involved, but it’s an afterthought. They’re not really driving the development of the solution. That’s a problem.”

Two students of The University of Texas Health Science Center at San Antonio will graduate this month with dual degrees, the MD as well as an MS in artificial intelligence, a program that was launched last year as the first of its kind. Click the graphic for an enlarged view of the program’s timeline.

Robert Pearl, MD, Stanford University School of Medicine professor and former CEO of The Permanente Medical Group, offers some pearls (no pun intended) from his new book, “ChatGPT, MD”:

• AI can help clinicians override confirmation bias, where they might favor data elements that fit their mindset and ignore others.
• The short-term use of AI will be to manage chronic conditions, such as to analyze data from wearables, and to guide patients with personalized health recommendations.
• AI’s ability to analyze EHR data will transform medicine by helping clinicians understand the optimal ways to manage diseases and perform procedures.
• The biggest challenges to reap AI benefits are (a) clinicians have to be willing to empower patients; and (b) the fee-for-service payment model must shift to value-based care because doctors won’t do something that reduces their income and they aren’t paid to keep people healthy.
• Pearl lists ChatGPT as a co-author of his book, which he says shortened its completion time from two years to six months. He fed all of his writing into ChatGPT so it could understand his voice and writing style, then had it suggest changes to his draft versions.

Educator Henry Buchwald, MD, PhD says that AI can help overcome “natural stupidity,” comparing it to his time in the Air Force where he flew his plane upside down because he trusted his instinct instead of the instrument panel. He offers this:

In contrast to AI, let us examine natural stupidity. Unfortunately, there is an abundance of that in our world, perhaps a preponderance. In medicine, we hope that every physician is intelligent, or at least competent. But that may not be the case. When I was still in active academic practice, conducting patient rounds, I asked a medical student for his thoughts on a patient’s differential diagnosis and how he would proceed to narrow the potential options. He whipped out his iPhone to consult an algorithm. I told him to put the instrument away and to speak from the knowledge base of his nearly four years of medical training to make his own analysis of variables. He proved that he had little knowledge of established facts and, even when prompted, could not produce a reasonable thought sequence.

After graduation, this student became someone’s doctor, treating afflictions, counseling fellow human beings. Fortunately, after a patient consultation, this doctor will be able to postpone diagnosis and therapy by waiting for laboratory and imaging results, allowing him time to go to his iPhone, consult the algorithms and then come to a conclusion for the patient. In essence, AI may be the patient’s ghost doctor. In some instances, medical AI might prevent the physician from crashing into an unappreciated mountain.

CLEW Medical’s learning models for predicting patient deterioration receive FDA’s 510(k) clearance

An Amazon Web Services blog post describes how Japan’s Fujita Health University used Amazon Bedrock’s managed AI service to generate discharge summaries, which it says reduced time requirements by 90 minutes to about 1 minute per patient.

An interesting Forbes article features digital health Investor Glen Tullman:

• He says that telehealth is dead, declaring that “all of the virtual care we’re doing now is going to move to chat.”
• His latest venture Transcarent – which has reached a $2.2 billion valuation for its chat-based primary care services —  is creating an AI chatbot that can answer a patient’s questions about their health plan, such as those that are related to deductibles and in-network doctors.
• Tullman says that Transcarent’s $100 million acquisition of 98point6 in 2023 gave it 1 million doctor-patient chat conversations that it is using for AI validation and testing.
• He says that Teladoc Health – onto which he unloaded Livongo for $18.5 billion in 2020 – saw its market cap shrink to around $2 billion because of poor leadership and the high cost of conducting video visits.

Sift Healthcare raises a $20 million Series B funding round to expand its AI tools that tie clinical information to financial outcomes to predict “adverse payment outcomes” and calculate patient responsibility upfront.

The American Hospital Association asks Congress to employ flexibility in any decisions to regulate AI in healthcare, proposing use of a sliding scale that is based on risk and the level of human oversight that is involved. AHA says that a one-size-fits-all regulatory approach could stifle innovation, saying that a better model is that of the FDA’s guidelines for defining Software as a Medical Device.

Apple announces the 2024 IPad Pro, the company’s first product to feature the newly announced, AI-optimized M4 chip. Prices start at $999 before trade-in credit for the 11-inch, one-pound model with Ultra Retina XDR display, 256 GB, and 12 MP front and back cameras. The company is speculated to be preparing all of its hardware to run AI without further upgrades, and the Wall Street Journal reports that Apple is working on a chip to run AI software in data centers.

Experts from drug maker Lilly say that AI will soon be able to design new drugs by using its own thinking instead of being trained on human-created datasets. They believe that even AI’s hallucinations will provide value by analyzing non-existent proteins within models.

Ohio State researchers train AI on de-identified medical claims data to predict the impact of available medical interventions on patient outcomes, which could supplement randomized clinical trials and explore new uses for existing drugs.

A UCSF study of emergency room visits finds that AI performed triage based on acuity as accurately as physicians. The authors note that since the commonly used Emergency Severity Index (ESI) is a rules-based triage scoring system that is straightforward for clinicians to calculate, AI might outperform them when making decisions that are based on both ESI score and patient details, such as answering difficult questions such as, “We have two patients and one available resuscitation bed – which one should get it?”

A Mother Jones article says that AI chatbots not only haven’t eliminated health misinformation, they have made it worse. It says that GPT can’t tell the difference between scientific information and the information it crawls from questionable websites, refers users to sites that sell scientifically unproven health products, and is easily fooled by information that sounds authoritative but isn’t. A science communication professor says that AI, unlike humans, doesn’t have the capacity for critical thinking, applying skepticism, and seeking out facts that disprove inaccurate information. I replicated the authors question to Microsoft Copilot about alternative cancer treatment programs, which included a link to the website of for-profit, cash-only Cancer Center for Healing, whose physician owner sells cancer treatments that have not been FDA approved.

Several hundred nurses picket Kaiser Permanente San Francisco Medical Center to express their concerns that KP, which promotes itself as a leader in healthcare AI, will use the technology to improve its margins rather than patient care.

HHS OCR and CMS publish a rule that prohibits the use of patient care decision support tools –- their new name for what they previously called “clinical algorithms” – to discriminate based on race, color, national origin, sex, age, or disability. It requires Covered Entities to identify and review their use of any tools that take those factors into account to make sure they do not discriminate. It lists areas such as prior authorization, medical necessity determination, screening, risk prediction, diagnosis, prognosis, clinical decision-making, treatment planning, healthcare operations, and resource allocation in which race or ethnicity inputs might create discrimination.

AI drug developer Xaira Therapeutics launches with $1 billion in capital. The company’s founding CEO is former Stanford University President Marc Tessier-Lavigne, PhD, who left that post in August 2023 when several of the research papers he published while working for Genentech were found to have used manipulated data.

Startup Dionysus Digital Health develops an AI-analyzed genetic test that it says can detect post-partum depression before symptoms appear. DoD has provided a $6 million grant for further study. The company hopes to earn FDA approval for the $250 test and have it covered by health insurance.

Quest Diagnostics will acquire PathAI’s Memphis-based digitized laboratory – the former Poplar Health, which it acquired in July 2021 — and convert it to Quest’s AI and digital R&D and solutions center to support its AmeriPath and Dermpath Diagnostics specialty pathology businesses. PathAI will continue to offer clinical trials services from its biopharma lab, which is a separate business.

Drug maker Moderna launches its own instance of ChatGPT that has been used by 80% of its employees. The company is using advanced analytics, image generation, and a library of 750 self-developed GPTs that help drive automation and productivity.  One of the GPTs evaluates optimal vaccine doses based on standard criteria and principles, supporting its conclusions with rationale, references, and charts that illustrate key findings, all of which are then reviewed by humans. The company identified its top 100 AI users to serve as champions and created an active internal AI forum. Moderna says that 40% of its active users have created GPTs and each user averages 120 ChatGPT Enterprise conversations each week.

Researchers find that using AI to analyze the high-risk ECGs of hospitalized patients was associated with a 31% drop in all-cause mortality, the first randomized clinical trial to show that AI saves lives.

A study finds that ChatGPT-4 performed poorly in evaluating the data of chest pain patients to determine whether they should be admitted. Researchers noted particular concern that the model would give different risk estimates and test ordering recommendations for the same set of patient data that it reviewed more than once.

University of Texas Southwestern Medical Center researchers find that ChatGPT 3.5 can extract pathological classifications from lung cancer pathology reports with 89% accuracy, with most misclassifications being caused by lack of specialized pathology terminology and its faulty interpretation of TNM staging rules (tumor, number of affected nearby lymph nodes, and the presence of metastasis). The test was repeated using ChatGPT 4, which improved the model’s performance by 5% but at a higher cost.

Wolters Kluwer Health publishes findings from a new survey focused on provider perceptions of AI. A few snippets:

• Eighty percent believe generative AI will improve patient interactions.
• Forty percent say they’re ready to start using generative AI in those interactions.
• Over 50% believe generative AI will save them time when it comes to summarizing patient data from the EHR, or looking up medical literature.
• Despite their enthusiasm for the technology, at least 33% say their organizations don’t have guidelines on how to use it.
• Providers are more enthusiastic about the technology than patients, with the majority of surveyed consumers in a previous study reporting they’d be concerned about using generative AI in a diagnosis.

AI-drafted physician messaging may not reduce response time to patient messages, but it does lessen cognitive burden, according to research out of UC San Diego Health. Lead researcher Ming Tai-Seale, PhD, explains: “Our physicians receive about 200 messages a week. AI could help break ‘writer’s block’ by providing physicians an empathy-infused draft upon which to craft thoughtful responses to patients.”
