Epic Systems on Oct. 21 introduced Connectors, which link outside developers' apps to its electronic health record so Epic's AI assistants can pull information from those apps and complete tasks in them.

Health care organizations can find developer-built Connectors in Epic's Showroom marketplace starting in March 2027 and can review what each one reads and changes before switching it on, the company said. Epic plans to begin testing with some health system partners by the end of 2026 and will charge developers to distribute Connectors, Fierce Healthcare reported. The announcement came at Epic's Open@Epic developer conference, where an Epic executive also said consumer chatbots that pull patient records are adding traffic and cost for health systems.

Elsewhere, the American Hospital Association asked the Food and Drug Administration to make AI developers primarily responsible for monitoring generative AI devices, and five large employers backed extending electronic prior authorization to self-funded health plans, the Centers for Medicare & Medicaid Services said.

In this episode

• Epic opens its AI assistants to third-party apps through Connectors, with marketplace listings from March 2027
• Consumer chatbots pulling patient records add traffic and cost for Epic customers; Epic adds event alerts to cut repeated data requests
• Hospital association asks FDA to make developers primarily responsible for monitoring generative AI devices after they are sold
• Amazon, Google, Meta, Oracle and Axon back extending electronic prior authorization to self-funded employer plans
• Nebraska Medicine shelves its in-house AI cancer registry tool after it reaches a little over 80% accuracy against a 95% bar
• FDA clears Elucid's FFR-IQ, which estimates fractional flow reserve from coronary CT angiography using plaque features
• Doximity adds UpToDate answers to its Ask clinical AI tool for clinicians at health systems that use both products
• FDA clears NeuroXT's NEXT-Cue, AI software for assessing whether mild cognitive impairment will progress to Alzheimer's dementia

What is Physician in the Loop?

How technological innovation is changing medicine for patients and the people who practice on the front lines.

Voice 1: This is Physician in the Loop, the daily briefing on AI in medicine. It's Thursday, October 22nd, 2026.

Voice 1: Epic says a hospitalized patient's AI assistant can now place their meal order directly into the hospital's dietary app, no staff member relaying it by hand.

Voice 2: That's the headline example from Connectors, the feature Epic introduced October 21st?

Voice 1: Right. Connectors let Epic's AI assistants, Emmie for patients, Art for clinicians, Penny for revenue cycle and operations staff, and custom agents built in Agent Factory, pull information from outside apps and complete tasks inside them. Epic's other example is bringing an ambulance's estimated arrival time into the emergency department.

Voice 2: Which companies are actually building these connectors?

Voice 1: Availity, Gozio Health, and VPL are among the first, covering coverage and prior authorization and claims work, hospital wayfinding, and tracking medication deliveries. Health systems will find them in Epic's Showroom marketplace starting in March 2027, and can review what each one reads and changes before switching it on.

Voice 2: So nothing happens automatically behind a hospital's back?

Voice 1: Epic's Johnston Thayer, its vice president of health informatics, told Fierce Healthcare, “there will not be new autonomous actions taken as a result of these capabilities.” Epic plans to start testing with some health system partners by the end of this year, and it will charge developers to distribute connectors.

Voice 2: What's actually connecting all this under the hood?

Voice 1: Epic will initially use the Model Context Protocol, an open standard for linking AI tools to other software.

Voice 2: Epic's own executives flagged a cost problem tied to a different kind of connection, from consumer chatbots.

Voice 1: What's going on there?

Voice 2: Seth Howard, Epic's executive vice president of research and development, said at the same conference that connections from consumer chatbots and individual access services are adding load to health system IT.

Voice 1: Any numbers on that?

Voice 2: At Advocate Health, patients linking MyChart accounts to ChatGPT rose more than 7,000% between July and August. Its chief information officer, Dr. Bobbie Byrne, said Advocate pays part of the cost from the resulting data requests and can absorb it for now.

Voice 1: Who's supposed to carry that cost long term?

Voice 2: Under Epic's model, health systems run the software and carry the infrastructure costs. Epic is supporting FHIR notifications, a standard that lets outside apps respond to an event instead of repeatedly checking for new data, and Byrne said she understands Epic is working with OpenAI to make the requests more efficient.

Voice 1: So the fix is in progress, but the bill is arriving now.

Voice 2: Regulators had a busy week too. The hospital association wants more of the oversight sitting with developers, not hospitals.

Voice 1: What exactly is it asking the FDA to do?

Voice 2: In October 19th comments on the FDA's discussion paper on generative AI devices, the American Hospital Association said vendors and developers “must be responsible for the ongoing performance, maintenance and integrity of the tools they market,” with performance metrics, thresholds that trigger review, and requirements to share performance data with providers.

Voice 1: Does it want the FDA judging these tools differently than it does now?

Voice 2: Yes. It asked the agency to judge risk by reversibility, safeguards, traceability of outputs, and likelihood of error, not just how autonomous a device is, and to work with the FTC on labeling that separates informational tools from ones that take action.

Voice 1: Does it want everything under FDA's umbrella?

Voice 2: No, it asked that clinical decision support and administrative AI stay outside FDA oversight. It also said rural, critical access, and safety-net hospitals may lack the staff for ongoing monitoring, citing its survey finding that 74% of hospitals already have multiple teams evaluating predictive AI.

Voice 1: That's a real constraint for the hospitals with the fewest resources to begin with.

Voice 2: A different group pushed on a different kind of paperwork problem this week. Five large employers, Amazon, Google, Meta, Oracle, and Axon, signed on to extend electronic prior authorization to self-funded health plans, CMS and the Labor Department said October 21st.

Voice 1: What does that actually change for those employees?

Voice 2: It brings the changes from the 2025 Prior Authorization Pledge to employers that sponsor self-funded plans. More than 180 million people, over 53% of Americans, get coverage that way, and those employers often rely on third-party administrators to handle prior authorization.

Voice 1: Did CMS say why this matters now?

Voice 2: Dr. Mehmet Oz, the CMS administrator, said patients and doctors “shouldn't have to fall back on faxes and paperwork” because of how a plan is funded.

Voice 1: Five companies is a start, but it's five companies, not every self-funded plan in the country.

Voice 2: Before we go, something to watch.

Voice 1: What's moving on the Epic agent story beyond Connectors themselves?

Voice 2: Earlier in October, five health systems told Becker's they were holding off on some Epic AI tools, and flaws found with Anthropic's model let some Epic configurations open records without an audit-trail entry.

Voice 1: Does that change what the trigger is that everyone's actually watching for?

Voice 2: No, the trigger stays the same: an agent placing an order in a U.S. hospital without a signature.

Voice 1: Something on the FDA side too?

Voice 2: Yes. The FDA's fiscal 2027 guidance list puts a draft on generative AI conversational devices for mental disorders on its top tier, and the vote on Heidi Overton's nomination for commissioner has been put off until after the midterm elections, according to STAT.

Voice 1: A commissioner vote on hold while the agency's own guidance list puts mental health chatbots at the top of its drafting priorities.

Voice 2: Odd timing for a framework that's supposed to settle who's watching these tools once they're already out the door.
