The New York Times covers physician use of Epic’s In Basket Art to create draft responses to patient questions that have been submitted using MyChart. Some major health systems decided not to use the technology over concerns that doctors would approve responses without reviewing them, while others thought that patients would recognize the message as AI generated and devalue it. An Epic study found that doctors are sending unedited responses to one-third of messages. Duke Health Chief Health Information Officer Eric Poon, MD, MPH says that Epic’s product creates drafts that are still “moderate in quality,” which keeps doctors vigilant in looking for mistakes, but ponders whether they will let their guard down as the AI gets smarter. A Duke colleague adds that it tried to get Epic’s product to stop giving clinical advice, but “we couldn’t take out its instinct to try to be helpful.”

OpenAI will roll out Advanced Voice to paying subscribers of ChatGPT this week. The enhancement adds speedier conversational responses, the ability to pause when interrupted, and additional voices. However, it reportedly does not support web search, custom GPTs, images, or unlimited use.

Google Cloud releases upgraded versions of its Gemini 1.5 chat-based AI assistant that it says are twice as fast at half the cost, with the capability of handling 1,000-page PDFs and hour-long videos. The company says that its Cloud and DeepMind divisions are developing new AI products and models and that developers are starting to use Gemini to create their own chatbots and voice assistants. Google has added the standalone Gemini app to Google Workspace.

The Association for the Advancement of Medical Instrumentation (AAMI) will work with the Consumer Technology Association to create standards for post-market market surveillance of non-prescription health devices  and for evaluating and assessing AI/ML products.

London-based Noki.ai announces an ambient AI medical companion that can transcribe visit conversions, automate scheduling, manage forms, verify insurance, display a patient dashboard, and exchange data in FHIR format. Monthly pricing ranges from free to $299 based on functionality and usage limits.

Ferrum Health, which offers a secure platform for health systems to deploy AI, raises $16 million in a Series A funding round. Co-founder and CEO Pelu Tran founded Augmedix in 2012, which at that time hoped to commercialize the use of Google Glass for medical documentation. He dropped out of Stanford’s medical school weeks before graduating to work on Augmedix full time, then left the company in 2018 and started Ferrum.

Healthcare AI call agent developer Hippocratic AI adds $17 million to its Series A funding round that was led by Nvidia’s venture arm, increasing its total raised to $137 million.

Research

A study finds that real-time screening of medical claims using AI can reduce healthcare fraud, waste, and abuse by allowing questionable charges to be reviewed before payment instead of after. Tests found that such screening reduced claim payments by 1.2%. 

Researchers from Brigham and Women’s Hospital use AI to improve the accuracy of results from the PREVENT cardiac risk calculator by calibrating it to local populations. The authors conclude that the black box nature of AI applications can be tailored while preserving their functionality.

Singapore’s health minister says that general practitioners will use AI for assessing health risks, prescribing drugs, and recommending lifestyle changes, which will eventually be powered by mandatory use of its national EHR program. Ong Ye Kung told conference attendees that, “We have medical records, we have genome data, we have lifestyle data, we have socioeconomic data, and the technology is already available. We can train very sophisticated, high parameters, AI models to identify risk factors and to predictive preventive care.” He says that Singapore’s biggest health challenge is the “buffet syndrome,” where patients are overtreated because their insurance pays.

AAMC News profiles David Fajgenbaum, MD, MBA, who as a medical student in 2010 was dying of organ failure but was saved by experimental chemotherapy. The Penn Medicine professor created Every Cure, which uses AI to score 3,000 approved drugs for their possible use in treating other conditions, which gets them into the hands of patients quickly and inexpensively. That organization was awarded $48 million in federal funding earlier this year.
