Artificial intelligence systems are already drafting clinical notes in some hospitals. However, a new study raises a critical concern: the tools used to verify their quality may be failing exactly where it matters most—clinical safety.
Imagine this scenario: your doctor finishes the consultation, shakes your hand, and as you walk out, an AI system has already generated a complete summary of your visit—symptoms, diagnosis, medication adjustments, and next steps.
What once sounded like science fiction is now becoming routine in many healthcare settings.
The promise is compelling: free healthcare professionals from hours of documentation so they can spend more time with patients. But alongside this progress comes a fundamental question: how do we know these AI-generated notes are truly accurate?
The hidden problem
To assess quality, hospitals and tech companies have relied on automated evaluation systems. These tools compare AI-generated text with a “reference note” and measure how closely the words match.
Here lies the flaw: these methods were originally designed for language translation—not clinical reasoning. And in medicine, a single word can change everything.
For example: a patient arrives with abdominal pain, nausea, and a fever of 38.5°C. The doctor suspects a urinary tract infection and prescribes standard treatment.
The AI generates the note… but omits the fever and changes the antibiotic dosage from every 6 hours to every 12 hours.
To a word-matching evaluation system, the note “looks” similar enough and is accepted as correct. To a clinician, it’s an error that could completely alter the patient’s management and prognosis.
So, to test these systems, researchers at University of Helsinki and Karolinska Institutet created synthetic clinical cases and deliberately altered them—removing key data, modifying facts, and rephrasing content in clinically meaningful ways.
The research team systematically searched Ovid Medline (MEDLINE is the world’s largest biomedical database, created by the U.S. National Library of Medicine.
Ovid is a commercial platform that allows you to search within MEDLINE using advanced tools) and Scopus (Scopus is a multidisciplinary database created by Elsevier. It covers not only medicine but also social sciences, engineering, psychology, economics, and more)
The review was prepared on 10 April 2025 for peer-reviewed studies (scientific articles that have undergone a formal evaluation process by independent experts before being published) that used LLMs (AI systems that produce and understand human language) to generate clinical notes and reported an evaluation of text quality. They then compared traditional evaluation tools with newer methods based on semantic understanding.
The findings are concerning: a verification tool may label a note as “correct” even when it contains clinically significant errors. Conversely, it may reject a note that is actually accurate.
The solution: a three-layer verification model
The study recommends moving away from single-system evaluation toward a layered approach, where each level compensates for the limitations of the others:
Layer 1: Semantic analysis. Ensures that clinical meaning is preserved beyond exact wording.
Layer 2: AI as evaluator. A secondary AI system identifies omissions, inconsistencies, or clinically relevant changes.
Layer 3: Targeted human review. A healthcare professional reviews only the high-risk areas flagged by the previous systems.
This approach allows healthcare institutions to scale AI adoption without compromising safety. Human oversight does not disappear—it becomes smarter and more efficient.
What this means for us
Trust in artificial intelligence is not given—it is built. AI holds the potential to transform healthcare in ways we are only beginning to understand. But that potential becomes real only when systems are evaluated with the right standards.
And I’m sure we all agree on this point: Medicine does not need artificial intelligence written texts that merely “look” correct. It needs texts that are correct. And above all, texts that are proved to tell the truth.
