When Algorithms Fail: Preparing for AI Incidents in Clinical Settings

Artificial intelligence is transforming healthcare, but its failures can lead to serious risks. Since mid-2024, over 10,000 AI-related safety incidents have been reported, highlighting issues like biased algorithms, data drift, and poor system integration. Examples include sepsis prediction models missing two-thirds of cases and AI tools recommending unsafe treatments. Hospitals face challenges with fragmented data, regulatory confusion, and clinician distrust of "black box" systems.

To address these risks, hospitals need:

The key takeaway? AI systems in healthcare require robust governance, clear processes, and a balance between automation and human judgment to ensure patient safety.

How AI Systems Fail in Healthcare

AI systems in healthcare often falter in three key areas: biased algorithms that perpetuate unequal care, models that degrade in accuracy over time, and integration issues that disrupt hospital workflows. Each of these failures carries unique risks for patients and medical staff. Below are real-world examples that highlight how these issues can jeopardize clinical outcomes.

Algorithmic Bias and Patient Harm

AI algorithms can unintentionally reinforce healthcare disparities, sometimes with serious consequences. For instance, a care-management algorithm used to screen between 100 million and 150 million people annually relied on healthcare spending as a stand-in for medical need. While this might seem neutral, it inadvertently reflected systemic inequities. Historically, Black patients have spent less on healthcare than White patients with similar illnesses, leading the algorithm to underestimate the severity of illness in Black patients by 26.3% ^[2][3]. As a result, many Black patients missed out on follow-up care programs they were qualified for.

Another example is IBM's Watson for Oncology. Between 2011 and 2018, IBM poured approximately $4 billion ^[3] into developing this AI system to recommend personalized chemotherapy treatments. However, Watson was trained on a limited, hypothetical dataset instead of comprehensive clinical data. When tested by Denmark's national cancer center, it aligned with local oncologists only 33% of the time ^[4]. Worse, it produced "unsafe and incorrect treatment recommendations" ^[3], leading to its rejection. By 2022, IBM sold off much of Watson Health for about $1 billion, marking a stark failure for the once-promising technology.

These examples show how biased algorithms can directly harm patients. But even when bias isn’t the issue, AI models can falter as data evolves.

Data Drift and Accuracy Loss

AI models trained on static datasets often fail to adapt to changes in real-world data, leading to a gradual decline in performance. This phenomenon, known as "data drift", can have serious consequences. Take the Epic Sepsis Model, which is deployed in hundreds of U.S. hospitals. External validation at Michigan Medicine revealed that the model’s sensitivity was just 33% at the recommended thresholds ^[3], far below the vendor’s claims. It flagged 18% of hospitalized patients as at risk but missed two-thirds of actual sepsis cases ^[4]. Doctors had to sift through 109 alerts to find one patient who truly needed intervention ^[4], resulting in widespread alert fatigue.

"Spectacular performance on synthetic tasks does not guarantee reliability at the bedside."

In some cases, models learn irrelevant correlations instead of true medical insights. For example, a COVID-19 detection model performed well during testing but failed in practice. It had learned to identify the X-ray machines used in COVID wards instead of detecting actual signs of the disease ^[4]. Alarmingly, between 90% and 96% of clinical decision support alerts are routinely ignored by physicians ^[4], reflecting a growing distrust in these systems.

Even when AI models are accurate, poor integration into hospital workflows can create additional challenges.

System Integration Problems and Treatment Delays

AI tools often struggle to integrate seamlessly with existing hospital systems, leading to inefficiencies that can delay care. A case in point is Google Health’s diabetic retinopathy AI, deployed in 11 clinics in Thailand. Over 20% of images were rejected as unsuitable ^[4], and infrastructure limitations meant nurses could only screen 10 patients in two hours. Instead of improving efficiency, the tool slowed down the workflow.

Similarly, UC Davis Health piloted the BioButton in 2023, a chest-worn sensor designed to continuously monitor vital signs like heart rate and temperature. The device was intended to detect conditions such as hemorrhagic strokes. However, nurses reported that its alerts often "led nowhere" ^[2]. Traditional methods proved faster at identifying patient issues, and the pilot was discontinued after a year. Adding to the problem, integrating and maintaining the AI system increased hospital costs by 25%-45%, exacerbated by limited GPU resources in many facilities ^[4].

These examples highlight the pressing need for better integration strategies and robust incident response plans to ensure patient safety and maintain operational efficiency.

Barriers to Safe AI Deployment in Hospitals

Deploying AI in hospitals isn't just about overcoming technical hiccups; there are deeper, systemic issues that make the process even trickier. From technical challenges to unpredictable regulations and fragmented data, these barriers can undermine the safety and effectiveness of AI in healthcare settings.

Black Box AI and Clinician Trust

One of the toughest challenges is the "black box" nature of many AI systems. Clinicians often find it hard to trust AI recommendations when they can't see how the system reached its conclusions. This lack of transparency becomes especially risky when AI systems fail silently, continuing to influence decisions even after their reliability has dropped off ^[5].

"Trustworthiness is not an intrinsic attribute of AI models but an emergent property of socio-technical systems in which AI is embedded." - Kunal Khashu, HCA Healthcare

The issue isn't just about opacity. Many AI tools lack basic safety features like confidence scores or uncertainty estimates, which could help flag when outputs are unreliable ^[5][6]. In fact, some centralized AI monitoring teams report that nearly half of their alerts are false positives ^[6]. This flood of unnecessary alerts can lead to "alert fatigue", where staff become numb to warnings and might miss genuine emergencies. As seen in the case of St. Rose Dominican Hospital, clinicians sometimes have to override AI recommendations to prevent harm ^[6].

Another major limitation is what AI systems can and cannot "see." Unlike human clinicians, AI models primarily analyze electronic medical records (EMRs) and miss out on critical sensory cues - like how a patient walks, speaks, or the feel of their skin - that doctors and nurses rely on every day ^[6]. Ziad Obermeyer, Associate Professor at UC Berkeley, explains this gap well:

"The models will never have access to all of the data that the provider has... all these subtle things that physicians and nurses see and understand about patients"

This gap between an AI's statistical performance and the safety standards needed for clinical trust is known as "validation debt." Bridging this gap is essential to gain clinicians' confidence ^[7]. But trust isn't the only hurdle - regulations are adding another layer of complexity.

Evolving Regulations and Compliance Requirements

In the United States, the regulatory landscape for AI is a patchwork, with federal and state policies often clashing. A December 2025 Executive Order, "Ensuring a National Policy Framework for Artificial Intelligence," promotes a hands-off approach to encourage innovation. Meanwhile, individual states are passing their own stricter rules, creating a maze of compliance challenges for hospitals ^[8].

State
Legislation

California
A.B. 489

Unlike pharmaceuticals, AI tools don't have a single federal authority overseeing their approval and use in healthcare. This leaves individual hospitals to shoulder the burden of testing and validating AI systems, leading to inconsistent safety standards across the country ^[6]. To add to the confusion, the 2025 Executive Order established an AI Litigation Task Force to challenge state laws that conflict with federal policy, leaving hospitals caught in the middle ^[8].

AI also introduces new legal risks. In 2025, the Department of Justice uncovered a scheme involving AI-generated fake patient consent recordings, resulting in $703 million in fraudulent claims ^[8]. On the flip side, federal agencies are also using AI to combat fraud. For example, the CMS launched the WISeR Model in January 2026, which uses machine learning to automate prior authorization for outpatient services in six states ^[8]. This dual role of AI as both a tool and a potential liability makes compliance even more challenging.

Fragmented Data and Quality Problems

AI systems in hospitals often struggle with fragmented and inconsistent data, which poses serious safety risks. While electronic medical records are a key data source, they frequently lack "off-file" information - like physical observations or subtle clinical cues - that are vital for accurate diagnoses and treatment ^[2]. Efforts to integrate EMR data with external sources, such as wearable devices or patient food logs, often fail to hold up in real-world conditions ^[2].

Take the case of Mount Sinai Health System's "Sofiya", an AI system used in cardiac-catheterization labs. While it saved 200 nursing hours in just five months by automating pre-procedure instructions, nurses still had to manually check its work to ensure safety and accuracy ^[6]. As Nigam Shah, Chief Data Scientist at Stanford Health Care, puts it:

"Ask nurses first, doctors second, and if the doctor and nurse disagree, believe the nurse, because they know what's really happening"

Another issue is "data drift", where real-world data starts to differ from the data used to train AI models, causing their performance to degrade over time ^[5]. Many AI systems also fail because they aren't properly integrated into clinical workflows or clash with the professional judgment of healthcare providers ^[5]. Addressing these data and integration challenges is essential to reduce risks and ensure AI systems can operate safely in hospitals.

Preparing for AI Failures Before They Happen

Hospitals need to act swiftly to identify and address AI failures to ensure patient safety. Early detection and quick responses are critical to minimizing risks when systems malfunction.

Building an AI Incident Response Plan

Creating an AI Incident Response Team (AI-IRT) is essential. This team should include professionals like ML engineers, data scientists, security analysts, legal experts, and clinical specialists ^[9][10]. Unlike traditional IT teams that focus on system crashes or breaches, an AI-IRT handles unique challenges like hallucinations, bias, and performance issues that might not trigger conventional alarms ^[9][10].

A six-phase cycle - Preparation, Detection, Containment, Eradication, Recovery, and Lessons Learned - provides a structured approach to managing incidents ^[9][10]. Detection can be particularly tough; AI-related problems take an average of 4.5 days to identify, compared to 2.3 days for standard IT issues ^[9]. Once detected, hospitals should assess the severity within 30 minutes to reduce harm ^[10]. Containment measures may include:

Scenario-specific runbooks can help address issues like hallucinations, algorithmic bias, prompt injection, and data poisoning ^[9][10].

Severity Level
Criteria
Response Action






Active harm (e.g., incorrect treatment, data breach)
Immediate AI-IRT activation; possible system shutdown




Confirmed safety risks or bias
Action within hours; apply circuit breakers




Performance issues or drift
Investigate within one business day




Minor concerns (e.g., isolated hallucinations)
Document and monitor trends

These steps aim to address the same gaps in integration and oversight that previously led to patient safety risks. However, automated measures alone aren't enough - human oversight remains a key component.

Maintaining Human Oversight of AI Systems

Despite advancements, clinical judgment is irreplaceable when AI outputs fail. Clinicians should document their initial assessments before viewing AI recommendations to avoid "cognitive anchoring", where AI suggestions overly influence their decisions ^[11].

AI systems should incorporate "algorithmic deferral", meaning they actively seek human input when confidence levels are low or when facing situations outside their validated scope ^[11]. As the Physician AI Handbook explains:

"Safety emerges not from flawless performance but from knowing when not to act"
.

Tracking override rates - how often clinicians reject or ignore AI recommendations - can reveal potential issues. Extremely low override rates (below 5%) might signal harmful automation bias, while high false positive rates could lead to alert fatigue and overdependence on AI ^[11].

Testing AI Systems Continuously

In addition to strong incident response plans and human oversight, continuous testing is vital for ensuring reliability. Hospitals should regularly validate AI systems by monitoring:

Statistical tests like the Kolmogorov-Smirnov test or Jensen-Shannon divergence can help detect data drift ^[9].

For example, in early 2026, Memorial Sloan Kettering Cancer Center tested an AI-based Incident Analysis and Learning System on 350 real-world clinical incidents. The system matched expert reviewers' conclusions 79% of the time and processed incidents in just under five seconds, compared to over two minutes manually ^[1].

Before rolling out updates or new models, hospitals should use staged deployments. Start small - testing with 5% of traffic in a controlled environment - and gradually scale to 25%, 50%, and eventually 100% ^[9]. Regular tabletop exercises simulating issues like hallucinations or prompt injection attacks can further refine response strategies and highlight monitoring weaknesses ^[10].

As Joe Braidwood, CEO of GLACIS, states:

"Compliance documentation isn't proof. Evidence is"
.

Conclusion

AI failures in healthcare aren't just theoretical - they're happening, and the consequences can be life-threatening. From biased algorithms leading to misdiagnoses to data drift reducing accuracy, these issues put patient safety at serious risk. The line between a minor issue and a disaster often depends on proactive preparation.

Right now, healthcare organizations are grappling with a governance gap. AI is being adopted faster than the systems needed to manage its risks. To address this, healthcare providers need clear governance structures that include human oversight, ongoing testing, and adherence to regulatory standards. These measures help tackle the "black box" problem that undermines trust and ensure accountability when things go wrong.

Specialized tools can make a big difference in managing these challenges. For example, Censinet RiskOps™ offers automated risk assessments, centralized dashboards, and real-time monitoring.

As AI systems become more advanced and capable of handling complex tasks autonomously, continuous oversight becomes even more essential. Healthcare leaders need to implement frameworks like the HSCC SMART toolkit to align AI solutions with critical clinical needs. They also need to adopt AI telemetry to prevent unapproved "shadow AI" systems from bypassing safety checks. Combining governance, human oversight, and the right tools allows hospitals to use AI effectively while prioritizing patient safety.
