Researchers find that their AI model that predicts how well schizophrenia patients will respond to antipsychotic medications performed well, but didn’t work when used in other studies. Experts warn that AI’s ability to advance medicine is limited by the methods that are used to collect, process, store, and analyze data. A co-author of the study predicts that it will be more than 10 years until AI will be able to analyze patient questionnaire results well enough for clinical use in psychiatry.

Cleveland Clinic says in its annual meeting that it is piloting AI for answering the questions of patients with chronic disease, creating ambient clinical documentation, predicting patient volume, and creating draft responses to questions that are submitted via Epic’s MyChart.

The hottest job in corporate America is the executive in charge of AI, according to the New York Times. It notes that Mayo Clinic in Arizona has hired its first chief artificial intelligence officer. 

An AAMC story describes the experience of physicians who are using AI to create documentation from recordings of their patient encounters. Eric Poon, MD, MPH (Duke Primary Care) says he is finishing his clinical schedule on time for the first time in his life, also noting that he didn’t realize how his EHR typing was slowing down the visit. Matthew Anderson, MD (Atrium Health) says he has a summarydraft in his hand 15 seconds after the visit ends. However, users say that ambient listening tools aren’t perfect in deciding what parts of the conversation to include or exclude, and some of them report that they spend quite a bit of time editing out extraneous information. They also say that it works well for quick visits, but less so when visits involve multiple medical issues.

Mass General Brigham researchers show that large language models can be trained to automatically extract social determinants of health from clinician notes. The finely tuned model identified 94% of patients who have adverse SDoH versus the 2% that could be identified using diagnostic codes. The model was trained to identify sentences that refer to employment status, housing, transportation, relationships, the availability of social support, and parental status. Bias was less likely than with GPT-4. The model was much smaller than ChatGPT models and results were better even thought the model was trained on just a few hundred patient records.

Switzerland-based cardiologists and researchers use AI to improve the usefulness of the atrial fibrillation detection capabilities of consumer wearables that are made by AliveCor, Apple, Fitbit, and Samsung. The study authors say that the single-lead ECG functionality alone is not clinically useful because of high numbers of inconclusive tracings, but the model reduced the percentage of those from 16% to 1.2%. They caution that opportunities for further studies will be limited as those manufacturers enhance their algorithms in undisclosed ways and may restrict access to their raw data. The study used cardiac diagnostics AI products from PulseAI.

A Michigan Medicine team uses AI to review physician notes for signs of risky drinking, which identified three times the number of patients than would have been flagged by diagnosis codes alone.

Researchers predict that AI will enhance the longer-term benefits of using wearables data, such as step tracking, either by directly providing health coaching or by analyzing wearables data to give human health coaches a better picture of the user’s health. The Time article observes that Google will add AI insights to users of its Fitbit devices, Google DeepMind is working on “life adviser,” and Apple will reportedly release an AI health coach next year. Experts suggest that while these projects are interesting, evidence that AI-analyzed wearables data has not been proven to improve outcomes or mortality.

AI researchers obtain the email addresses of 30 New York Times employees by feeding ChatGPT some known addresses and then asking for more via its API, which bypasses some of ChatGPT’s privacy restrictions. The article notes that AI companies can’t guarantee that their systems haven’t learned sensitive information, although AI tools are not supposed to recall their training information verbatim. Training on inappropriately disclosed medical records weren’t mentioned in the article, but should be concerning.

Three Stanford graduate students develop a tool that can accurately guess where a photo was taken by using AI that was trained on Google Street View. The system was trained on just 500,000 images of Google Street View’s 220 billion but can guess the country 95% of the time and can usually guess the location of a photo within 25 miles. The system beat a previously undefeated human “geoguessing champion.” Civil liberties advocates worry that such a system, especially if it is ever rolled out widely by Google or other big tech firms, could be used for government surveillance, corporate tracking, or stalking.

An expert panel that was convened by AHRQ and the National Institute on Minority Health and Health Disparities offers guiding principles for preventing AI bias in healthcare:

  • Promote health and healthcare equity through the algorithm’s life cycle, beginning with identifying the problem to be solved.
  • Ensure that algorithms and their use are transparent and explainable.
  • Engage patient and communities throughout the life cycle.
  • Explicitly identify fairness issues and tradeoffs.
  • Ensure accountability for equity and fairness in AI outcomes.

Clinical geneticist and medical informaticist Nephi Walton, MD, MS warns that AI is convincing even when it is wrong. He asked ChatGPT how to avoid passing a genetic condition to his children and it recommended that he avoid having children. He says AI has improved, but the way that it is trained is a problem because it pushes old evidence and guidelines to the top while neglecting new information.

Microsoft research VP Peter Lee, PhD provides thoughts about AI in healthcare:

  • It won’t be long before doctors will refuse to practice medicine without the assistance of AI.
  • Bing and ChatGPT are good at deciphering lab test results and explanation of benefits, where they can be asked “are any of these results concerning“ or “do I owe money.”
  • He and his sisters asked GPT-4 to review their father’s medical records, then list the three best things to ask the specialist in their 15-minute visit.
  • He says that GPT-4 is “almost superhuman” in its ability to serve as a second set of eyes for a physician in reviewing patient information and the doctor’s diagnosis by being asked, “Did I miss anything, or should I consider something else?”
  • Lee warns doctors not to think of ChatGPT as a computer that has perfect recall and performs perfect calculations, but rather as a “personal intern” whose work requires review.
  • AI doesn’t follow the regulatory framework of a software medical device, so it’s up to the medical community to take control of how and when it it used.

The estates of two deceased men sue UnitedHealth Group, claiming that the company uses AI algorithms to deny care to seniors who are enrolled in its Medicare Advantage plans. The complaint says that the AI system that UHG gained in its 2020 acquisition of NaviHealth has a 90% error rate and creates generic care recommendations that are used to override physician assessments of medical necessity, placing the Medicare Advantage patients at a disadvantage compared to traditional Medicare. A previous report found that patients who were entitled to up to 100 days in a nursing home following hospital discharge were usually cut off within 14 days by UHG.

Elsevier and OpenEvidence create an early access version of ClinicalKey AI, which allows doctors to enter patient information that is matched against Elsevier’s medical journal data to help them make clinical decisions. OpenEvidence’s original system is available for demonstration.

OpenAI pauses new signups for ChatGPT Plus due to a user surge following the company’s November 6 DevDay. The company also acknowledges that it is working on GPT-5, which will require more public and proprietary data sets.


Business

The CEO of an AI-powered robotics company says that the factors that made ChatGPT successful – training on a vast and diverse dataset and aligning the model’s response with what humans find useful – are being applied to AI robots that can understand their surroundings, make decisions, and adapt to changing circumstances. He predicts widespread deployment of robots that can perform object manipulation in 2024.

Research

Researchers in Australia refer to large language models that have limited guardrails as “weapons of mass disinformation” in a JAMA Internal Medicine article, where they describe using ChatGPT to create 102 disinformation blog posts about vaccines and vaping. Creation of the posts that totaled 17,000 words, which included fake patient and clinician testimonials and scientific-looking references, took just over one hour. Additional OpenAI tools contributed realistic images and a deep-fake video.

AI outperformed tissue biopsies in grading the aggressiveness of retroperitoneal sarcoma, which could potentially spare low-risk patients from unnecessary treatments and tests.

Tech-heavy medical practice operator Forward Health develops a standalone, app-powered  medical station it calls the CarePod, which it hopes to place in malls and office buildings where members will pay $99 per month for access. Founder and former Google computer scientist Adrian Aoun, who says “I don’t even believe a doctor’s office should exist,” hopes to turn healthcare into a product rather than a service. CarePods are powered by a large language model that uses medical research data to create care plans. The company just raised a $100 million Series E round and hopes to launch 25 CarePods initially and scale to 3,200 within one year. Aoun says he hopes to enhance the machines to perform open heart surgery within the next 20 years.

Adweek reports that a hospital shut down its marketing team over compliance problems after it tested ChatGPT.

A Washington Post opinion piece by Leana Wen, MD, MSc describes Kaiser Permanente’s use of AI to flag patients whose condition is deteriorating using near real-time data whose patterns might otherwise be overlooked. She says that KP’s key difference is that it sends the alerts to an offsite team of nurses to decide whether the hospital’s rapid response time should be deployed. The original study she references was published in November 2020.

CNN says that MSN.com and Microsoft Start are featuring bizarre, inaccurate stories that are generated by AI instead of the editors it has fired. The company published an article about a woman’s death that it lifted from The Guardian, then added a “pathetic, disgusting” poll that invited readers to speculate on whether she died by murder, accident, or suicide. One of the laid off editors says the company features stories from small, unreliable sources that provide little information about their ownership or editorial standards. The story above that called a deceased NBA player “useless” was speculated to have resulted from AI that translated the original source’s article from English to another language and back again to hide plagiarism.

Washington University in St. Louis launches the AI for Health Institute, which will involve a collaboration of its engineering and medical schools.

NPR Shots covers doctors using AI for diagnosis, including a Mass General infectious disease doctor who is using the AI-enhanced version of Wolters Kluwer’s UpToDate — NPR calls it “Google for doctors” — that can conduct a conversation rather than simply looking up keywords in medical references. Other AI uses mentioned are interpreting diagnostic images, summarizing a patient’s medical history in preparation for their appointment, and allowing AI-assisted primary care physicians instead of specialists to care for some patients.

Amazon begins rollout of AI-powered warehouse robots that it predicts will speed up order fulfillment by 25%. The system’s robotic arms and computer vision identify the correct item and send it to workers, which speeds throughput and places items at waist level to reduce worker injuries.


Research

A Stanford medical school study warns that AI chatbots may worsen health disparities for black patients by perpetuating race-based medical ideas that are known to be inaccurate. When asked to describe differences in skin thickness, lung capacity, and kidney function for a black man, the chatbots provided erroneous information instead of accurately stating that no differences exist. Some experts question the usefulness of the study’s conclusions since doctors shouldn’t be using chatbots to make medical decisions.

Researchers create software that uses AI to enhance CT images to produce MRI-quality information, which they say could be used to improve diagnosis in primary care.


Other

A Nature article predicts a rise in “generalist medical AI,” in which models that are trained on large data sets can mimic the broad analysis of a physician instead of performing a single function. It notes these challenges to AI in healthcare:

  • AI can’t be trusted to make unreviewed decisions.
  • Early medical imaging AI tools were trained on available imaging data that allowed them to perform tasks for which doctors don’t need help, such as detecting pneumonia.
  • Individual tools don’t reflect the cognitive work of radiologists, and the plethora of one-trick AI tools could result in “an IT soup.”
  • ChatGPT-like “Foundation models” that are trained on broad data sets of images, text, and other information can offer more capabilities than supervised learning, in which experts might analyze chest x-rays and label them as “pneumonia” or “not pneumonia” to train the system.
  • Few institutions recognize that diagnostic AI models have usually been validated against the same data set that they were trained on, which in the absence of external validation makes it impossible to see if they are actually beneficial.

I hadn’t tried Google’s Bard lately, but enhancements that were release a few weeks ago give it some advantages over ChatGPT:

  • It can access up-to-date information, such as news headlines and stock market information.
  • It integrates with Gmail, Docs, and Drive to find or summarize content.
  • Extensions are supported for Google-owned content, such as Maps and YouTube, and can be invoked specifically by using a keyword such as as @YouTube.
  • Bard’s initial responses can be double-checked via a Google search by clicking a button.
  • It can include images in its responses.

image

I also experimented with Pi, which terms itself as a “personal AI assistant” that emphasizes friendly, personal, and supportive responses. It serves as a polite sounding board, more of an AI companion than a brute force data retrieval engine, and it can conduct natural-sounding conversations. Developer Inflection AI recently raised $1.3 billion at a $4 billion valuation.

OpenAI adds voice capabilities to the ChatGPT mobile app, which can carry on a conversation with the user through one of several available natural-sounding voices. Existing voice assistants such as Alexa, Siri, Google Assistant, and Cortana will need to follow quickly or risk becoming instantly obsolete. 

Rumors suggest that OpenAI will soon launch AI-powered autonomous agents, which can interact with other software such as email or calendars to complete tasks without supervision.

Vanderbilt University Medical Center develops an EHR-embedded AI tool to identify pediatric patients who are at risk for blood clots. Outcomes were no better than for patients in the control group, however, which the researchers say may be due to physicians rejecting the tool’s recommendation to start blood-thinning therapy only 25% of the time due to fears of causing a major bleed. Yale medical school dean F. Perry Wilson, MD, MSCE observes that the VUMC study illustrates a key point that making accurate predictions is table stakes that vendors shouldn’t launch an “accuracy arms race” since “even perfect prediction is useless if no one believes you or if they don’t change their behavior.”

ChatGPT performs at least as well as primary care physicians in choosing treatment options for newly diagnosed depression, and unlike doctors, it does not exhibit gender or socioeconomic bias. ChatGPT nearly always recommends psychotherapy for mild cases versus the 4% of PCPs who do so. It also favors using antidepressants alone for severe cases, while doctors usually add anxiolytics or hypnotics.

A Klick Labs study finds that AI analysis of a 10-second recording of a person’s voice can determine if they have Type 2 diabetes with nearly 90% accuracy. The company says that the non-intrusive, accessible approach will allow screening large numbers of people for Type 2 diabetes and potentially other chronic conditions.

Researchers are surprised to find that ChatGPT does a poor job of reviewing urology residency application letters.

Experts predict that AI will play an outsized healthcare role in Canada because of clinician shortages in rural areas, with initial use in creating clinician documentation, providing easier access to patient records, helping with staff scheduling, and reviewing digital images.

Healthcare AI experts list ways that AI can help in healthcare, which include providing patient-friendly explanations, performing back office functions, predicting next events in a patient’s journey, analyzing images, keeping patient data private, and training itself. On the downside, it can create disinformation that sounds plausible, introduce bias in agreeing with what the user says, provide a false sense of security, and cause professionals to question whether their knowledge or careers are obsolete.

Microsoft introduces new healthcare-related tools to its Fabric analytics platform that can assemble and standardize data from multiple sources – such as EHRs, imaging systems, lab systems, medical devices, and claims data – and present it in a single view. The company also announced Azure AI Health Bot, which can answer staff questions about treatments and protocols and patient portal queries about symptoms and medical terms. Microsoft also announced a text analytics solution, along with generative AI models that create a patient history, simply medical reports into patient-friendly language, and help radiologists identify possible radiology report errors.

Google Cloud rolls out AI-powered clinician search for its Vertex AI Search platform. The company says it will speed up clinician EHR searches and to perform more complex operations such as suggesting billing codes or determining if patients meet enrollment criteria for clinical trials.

FluidAI Medical raises $15 million in a Series A funding round. The company offers an postoperative patient monitoring tool, powered by sensors and AI, that warns surgeons of anastomotic leaks in the GI tract that has an 8% surgical incidence with 12% mortality. The company is based in Canada and its product has not been cleared for sale in the US, although it lists Cleveland Clinic and Texas Medical Center as partners.


Research

Researchers say that clinical use of AI-powered predictive models feeds data back into the EHR on which model updates are trained, which will then reduce their accuracy when their training is updated. The authors observe that retraining can actually degrade model performance, as updated EHR information disrupts the connection between presentation and outcome. They recommend that health systems document the machine learning predictions that are used on a given patient and warn that a “model-eat-model world” can render an individual model and future models worthless.


Other

Biomedical researchers tell Stat that nobody knows if a given healthcare algorithm is useful because the companies that develop them don’t share data with researchers or anyone else. The authors propose that a federal agency test algorithms against a standard test set and publish their accuracy results, including a breakout by demographic groups, that FDA would use in reviewing a product for approval. They note as a precedent NIST, which evaluates facial recognition software in publicly available reports.
