Testing AI in Medicine: Why Published Studies Are Not Enough

There are two very different ways to evaluate artificial intelligence in medicine. One happens in journals. The other happens in real time — at the point where clinicians, patients, and decisions intersect.

Traditional research follows a familiar path. Data is collected, experiments are designed, results are analyzed, and papers are published after months or years of review. The conclusions are careful, the methods are structured, and the statistics are clean. This process gives us credibility. It tells us what an AI system was capable of under controlled conditions at a specific moment in time.

But there is a fundamental limitation.

By the time a study appears in print, the AI it evaluated has already evolved. These systems are not fixed. They change continuously — updates are introduced, behaviors shift, and performance can improve or deteriorate without clear visibility to the end user. What was tested in a study may no longer reflect what clinicians are actually using. In many cases, published research becomes a form of postmortem analysis — accurate, but no longer current.

In contrast, there is another way to evaluate AI — one that mirrors clinical practice itself.

Real-time testing does not wait. It engages the system as it exists today. It uses real anatomy, real imaging, and real clinical questions. The goal is not just to see whether the AI can produce an answer, but to understand how it behaves under pressure.

Mistakes are not filtered out — they are exposed. Incorrect answers, faulty reasoning, and overconfidence become part of the evaluation. They are examined, challenged, and corrected openly. This creates a dynamic form of public peer review, where feedback is immediate and relevance is constant.

This is the environment I work in. This is not a formal laboratory study. It is a real-time educational stress test of AI using anatomy, imaging, clinical reasoning, and public correction.

Unlike institutional studies that evaluate AI in controlled settings, my approach tests AI in the same way clinicians encounter problems — unfiltered, variable, and often imperfect. The audience is not limited to researchers. It includes practicing clinicians, trainees, and the public. Every case becomes both a test and a teaching opportunity.

What becomes clear in this setting is something traditional studies often fail to capture: behavior in real-world conditions.

An AI model may perform well on curated datasets yet struggle with everyday clinical variability. It may provide confident answers that are incorrect. It may recognize patterns without truly understanding anatomy or pathology. These are not theoretical risks — they are observed directly when AI is tested in real time.

This does not diminish the value of peer-reviewed research. On the contrary, it remains essential. It establishes baseline performance, validates methodologies, and builds scientific trust. But it answers a different question.

Research asks: What could this AI do under ideal conditions?

Real-time testing asks: What is this AI doing right now?

That distinction is critical.

In medicine, accuracy is not abstract. It directly influences education, clinical judgment, and patient care. If AI is to be used as a teaching tool or clinical aid, its limitations must be visible. Errors cannot be hidden behind polished results or selective reporting.

There is also an educational advantage to this approach. Real-time testing not only evaluates AI — it reinforces clinical thinking. It emphasizes anatomy, correlation, and verification. It reminds us that no answer, whether generated by a machine or a human, should be accepted without understanding.

This is where both approaches must come together.

Institutional research provides structure, validation, and long-term credibility. Real-time testing provides immediacy, transparency, and practical relevance. Each fills a gap left by the other.

Together, they offer a more complete and honest picture of AI in medicine. Published research tells us what AI has achieved under controlled conditions. Real-time testing shows us what AI is actually doing today, in front of real users, with real consequences.
