The 10 Most Catastrophic AI Failures in Healthcare November 2025 (LIVES LOST!)
Here’s your definitive countdown of the AI failures in healthcare November 2025 that are destroying patient trust, costing lives, and proving the technology isn’t ready for medicine.
10. AI Missed 66% of Critical Health Conditions That Could Kill Patients
Detection failure topped deadly AI failures in healthcare November 2025 when machine learning missed two-thirds of life-threatening injuries, according to Axios reporting on Nature study.
The Study: Research published in Nature’s Communications Medicine journal tested machine learning models commonly cited in medical literature for predicting patient deterioration.
The Catastrophic Results: Models trained exclusively on existing patient data didn’t recognize about 66% of injuries that could lead to patient death in the hospital.
The Danger: These AI failures in healthcare November 2025 mean hospitals using these systems are essentially flying blind—missing critical warning signs in two-thirds of cases where patients are deteriorating toward death.
The Context: About 65% of U.S. hospitals use AI-assisted predictive models, most commonly to figure out inpatient health trajectories. If those models miss 66% of critical conditions, they’re actively dangerous.
Why It’s Deadly: When AI fails to detect life-threatening deterioration, patients die unnecessarily. These AI failures in healthcare November 2025 prove that pure data-driven training without medical knowledge creates systems that look sophisticated but function catastrophically.
9. FDA’s Elsa AI Tool Cites Fake Research Studies
Regulatory disaster created one of the most embarrassing AI failures in healthcare November 2025, per Healthcare Brew.
The Tool: The FDA’s AI tool called Elsa was designed to accelerate drug and medical device approvals—one of the most critical regulatory functions.
The Failure: In July 2025, CNN reported that Elsa generated fake research studies in its citations, completely undermining the regulatory review process.
The Implications: These AI failures in healthcare November 2025 mean drugs and devices might be approved based on fabricated research that the AI hallucinated into existence.
Why It’s Terrifying: The FDA exists to protect patients from unsafe drugs and devices. When the agency’s own AI makes up research to justify approvals, the entire regulatory system becomes compromised. These AI failures in healthcare November 2025 could allow dangerous products onto the market.

8. Google’s Med-Gemini Mentions Nonexistent Body Part in Research
Academic failure created reputational AI failures in healthcare November 2025 for Google’s medical AI, according to The Verge reporting via Healthcare Brew.
The Model: Google’s healthcare AI model, Med-Gemini, was designed to assist with medical research and diagnosis.
The Error: In a 2024 research paper that gained attention in 2025, Med-Gemini mentioned a body part that doesn’t exist in human anatomy.
The Problem: Medical professionals rely on research papers for clinical guidance. When AI generates anatomically impossible information that gets published, it corrupts medical knowledge.
Why It’s Dangerous: These AI failures in healthcare November 2025 prove that even Google—with unlimited resources—can’t make medical AI that understands basic human anatomy. If it hallucinates body parts, what else is it making up?
7. AI Chatbots “Highly Vulnerable” to Attacks Promoting False Medical Info
Security catastrophe revealed disturbing AI failures in healthcare November 2025, per Healthcare Brew.
The Study: Research from Mount Sinai health system in New York released on August 2, 2025, found AI chatbots are “highly vulnerable” to attacks promoting false medical information.
The Mechanism: Attackers can manipulate AI chatbots to provide dangerous medical misinformation by crafting specific prompts or exploiting training data weaknesses.
The Risk: Patients using AI chatbots for medical advice could receive actively harmful recommendations—from wrong medication dosing to dangerous treatment suggestions.
Why It’s Alarming: These AI failures in healthcare November 2025 mean malicious actors could weaponize medical AI to spread misinformation at scale. One successful attack could harm thousands of patients simultaneously.
6. 85% of Healthcare AI Projects Fail Due to Poor Data Quality
Systematic failure topped AI failures in healthcare November 2025 with industry-wide collapse, according to Orion Health analysis citing Gartner.
The Statistic: Gartner estimates that 85% of AI models fail due to poor data quality—a rate even higher than the general 42% AI project failure rate.
The Healthcare Multiplier: Healthcare data is uniquely problematic—fragmented across electronic health records (EHRs), labs, and imaging systems, often inconsistently structured and full of gaps.
The Consequences: These AI failures in healthcare November 2025 mean hospitals are spending billions on AI systems that don’t work. Without rigorous data curation, models reinforce existing biases or generate clinically unsafe recommendations.
Why It’s Systemic: When 85% of projects fail, that’s not bad luck—it’s systematic industry failure. These AI failures in healthcare November 2025 prove the entire approach is fundamentally flawed.
5. WHO Warns “Precipitous Adoption” Could Lead to Patient Deaths
Global health authority issued dire warnings about AI failures in healthcare November 2025, per Healthcare Dive.
The Warning: The World Health Organization warned that the “meteoric” rise of AI tools in healthcare threatens patient safety if caution is not exercised.
The Quote: “Precipitous adoption of untested systems could lead to errors by health-care workers, cause harm to patients, erode trust in AI and thereby undermine (or delay) the potential long-term benefits and uses of such technologies around the world.”
The Context: Because of excitement over ChatGPT, Bard, and similar platforms, device developers are “tossing aside the caution that normally would be applied toward new technologies.”
Why It’s Critical: When WHO—the global authority on health—issues warnings about AI failures in healthcare November 2025, that’s not fear-mongering. It’s recognition that rushing unproven technology into medicine will kill people.
4. 55% of Medical Professionals Say AI Not Ready for Medical Use
Professional rejection highlighted AI failures in healthcare November 2025 through physician surveys, according to PRS Global’s healthcare AI analysis.
The Statistic: 55% of medical professionals believe AI isn’t ready for medical use yet—more than half of doctors don’t trust the technology with patient care.
The Reasons: Physicians cite concerns about job security, autonomy loss, compromised clinical judgment, and lack of experience with AI technology.
The Adoption Problem: Healthcare workers’ resistance isn’t irrational fear—it’s based on witnessing AI failures in healthcare November 2025 firsthand. They see the mistakes AI makes and refuse to stake patients’ lives on flawed systems.
Why It Matters: When the majority of medical professionals reject AI as unready, those are the people who actually understand medicine saying the technology doesn’t work. These AI failures in healthcare November 2025 reflect clinical reality, not hype.
3. AI Could Exclude 5 Billion People Through Biased Training Data
Global inequality crisis became one of the most harmful AI failures in healthcare November 2025, per World Economic Forum analysis.
The Scale: Nearly 5 billion people living in low and middle-income countries remain largely invisible in AI diagnostic models, risk assessments, and treatment algorithms.
The Consequences:
- Misdiagnosis and harm: Patients in underrepresented regions receive less accurate or inappropriate diagnoses, leading to delayed or ineffective treatment
- Erosion of trust: Communities experiencing systematic errors may distrust not only digital technologies but healthcare institutions entirely
- Deepening inequality: As AI improves outcomes in wealthy nations, the Global South gets left further behind
The Example: “A cancer detection algorithm that misses tumours on darker skin isn’t just a technical error; it is a life-or-death issue.”
Why It’s Catastrophic: These AI failures in healthcare November 2025 prove that instead of democratizing medicine, AI is reinforcing and amplifying existing global health inequalities. Billions of people are excluded from benefits while being exposed to AI’s risks.

2. Liability Uncertainty Means Nobody Knows Who’s Responsible for AI Errors
Legal chaos topped AI failures in healthcare November 2025 as courts struggle to assign blame, according to Healthcare Brew’s malpractice analysis.
The Problem: Though there haven’t been any notable AI malpractice suits yet, nobody knows who’s liable when AI makes medical mistakes—the doctor, the hospital, or the AI company.
The Scenarios:
- If an AI diagnostic tool misidentifies a patient as stable when they need immediate intervention, who’s sued?
- If AI recommends the wrong medication dosage and the doctor follows it, who’s responsible?
- If an AI scheduling system creates gaps in critical care, who pays damages?
The Medical Board Stance: The Federation of State Medical Boards suggested in April 2024 that clinicians, not AI makers, should be liable—essentially making doctors responsible for technology they didn’t create and can’t fully understand.
Why It’s Paralyzing: These AI failures in healthcare November 2025 create legal uncertainty that prevents accountability. Doctors won’t use AI if it exposes them to lawsuits. Patients can’t get justice if nobody’s responsible. The entire system breaks down.
1. United Healthcare AI Wrongly Denied 90% of Elderly Patient Claims (#1 Deadliest)
Systematic harm topped all AI failures in healthcare November 2025 as the most evil use of AI in medicine, according to Monte Carlo Data’s AI fails report.
The Lawsuit: A November 2023 federal lawsuit (still making headlines in 2025) alleged United Healthcare used a faulty AI model to systematically deny healthcare coverage to elderly Medicare Advantage patients.
The AI System: nH Predict determined how long patients should receive post-hospital care in nursing facilities, frequently overriding physician recommendations.
The Catastrophic Error Rate: When patients appealed denials, 90% were reversed in their favor—proving the AI was wrong nearly every time it denied care.
The Harm: Many elderly patients never appealed, potentially going without medically necessary care their doctors prescribed. Some may have died without the care AI wrongly denied them.
The Intent: The 90% reversal rate proves this wasn’t an innocent mistake—the AI appears designed to deny claims to save United Healthcare money, overriding medical judgment to boost profits.
Why It’s #1: These AI failures in healthcare November 2025 represent the darkest possible use of the technology—deploying AI specifically to deny life-saving care to vulnerable elderly populations. The 90% error rate proves the system was never about medicine—it was about denying claims regardless of medical necessity. When AI is weaponized against the most vulnerable patients to increase insurance profits, that’s not healthcare innovation—it’s systematic cruelty enabled by technology.
Common Themes in AI Failures in Healthcare November 2025
