Artificial intelligence is transforming medicine, especially in routine screenings like colonoscopies, breast cancer detection, and eye exams. But I recently came across a fascinating study from Poland that made me pause: it suggests that doctors might actually lose some of their skill when they get too used to relying on AI assistance. This raised a tough question – could AI‘s help sometimes make doctors less sharp?
How AI is changing the way doctors spot abnormalities
According to research published in The Lancet Gastroenterology and Hepatology, gastroenterologists in Poland using an AI system designed to detect polyps during colonoscopies became about 20% worse at spotting polyps and abnormalities when the AI was switched off. This happened after only a few months of using the AI tool. The system works by highlighting suspicious areas in real-time video with a green box, directing the doctor’s attention to potential issues.
The lead researcher, Dr. Marcin Romańczyk, noticed that this decline wasn’t just a minor blip. He suspects that doctors began subconsciously waiting for the AI’s cues rather than actively searching, essentially letting the AI guide their eyes instead of relying on their own trained judgment.
Doctors appeared to become quickly dependent on AI to catch what they might miss on their own.
Is the solution really making us dependent, or are there other factors at play?
That said, not everyone is convinced this drop in detection rates means doctors are losing their hard-earned skills. Johan Hulleman, a researcher from Manchester University, pointed out that three months might be too short a timeframe to lose decades of expertise. He also questioned whether natural statistical differences in patient populations during the study could explain the results. For example, age or other clinical factors might have influenced the findings.
Another layer of complexity is the unknown ground truth—we don’t definitively know how many polyps were truly present to be found. So, how many of those “missed” by doctors without AI help were actually significant? These uncertainties make interpreting the outcomes challenging.
Still, there’s a concept called the “safety-net effect” that researchers have noticed in similar contexts, like mammogram screening. The presence of AI support can sometimes unintentionally encourage less thorough manual reviews since the user trusts the AI as a backstop.

What this means for the future of AI in medicine
AI tools are spreading quickly across healthcare, offering some undeniable benefits by helping doctors catch abnormalities that could be easily overlooked. Yet, this study highlights an important risk: when doctors get used to AI assistance, they might not be as vigilant on their own. It’s a reminder that great tech isn’t a substitute for expertise—it should complement it.
Dr. Romańczyk emphasizes that while the green AI highlight boxes were beneficial, there is little data on the long-term impact of AI on doctor skills. Since this technology wasn’t part of traditional medical training, healthcare professionals are navigating uncharted territory, balancing trust in AI with retaining their own diagnostic instincts.
There’s a clear need for more research to understand how AI integration affects medical decision-making, beyond just accuracy statistics. How do we train doctors to use AI effectively without becoming overly dependent? How can AI be designed to foster better human skills rather than replace them?
Key takeaways:
- AI can significantly assist in detecting medical abnormalities in real-time screening.
- Doctors may inadvertently reduce their own detection skills after frequent AI use.
- Proper training and further studies are essential to understand and mitigate potential over-reliance on AI.
Being an AIholic, I find this balance especially fascinating. AI is undeniably powerful, but the human touch and critical thinking still matter deeply when it comes to healthcare. The future will likely involve finding new teaching methods and tools that enhance, rather than erode, the invaluable expertise doctors bring to the table.
