The findings showed that adenoma detection rates decreased from 28.4% prior to AI exposure to 22.4% after its introduction, while AI-assisted colonoscopies achieved a detection rate of 25.3%.

This decline in detection rates suggests a potential 'deskilling' effect, where reliance on AI tools may diminish endoscopists' ability to detect precancerous growths independently.

A recent study published in The Lancet Gastroenterology & Hepatology reveals concerning implications of artificial intelligence (AI) use in colonoscopies, particularly a potential deskilling effect among experienced endoscopists.

Researchers analyzed 1,442 colonoscopies in Poland, comparing adenoma detection rates before and after the introduction of AI-assisted polyp detection systems in 2021.

Omer Ahmad from University College London emphasized the need for performance-monitoring guidelines and educational programs to mitigate the risks of deskilling.

The study's results prompt a reevaluation of training paradigms in endoscopy, advocating for new frameworks that balance AI utilization with the preservation of essential procedural skills.

Dr. Marcin Romanczyk, a co-author of the study, noted that this research is the first to indicate a negative impact of AI on healthcare professionals' performance in a patient-relevant task.

The study's observational design and focus on experienced endoscopists limit its generalizability, highlighting the need for further research involving less experienced professionals.

The AI tool in question was designed to identify precancerous polyps, thereby increasing the likelihood of early cancer detection and removal.

Overall, the study underscores the importance of examining the interaction between healthcare professionals and AI systems to enhance their collaboration and effectiveness.

Cognitive offloading, where specialists depend on AI for critical decision-making, may hinder their visual recognition skills and lead to decreased vigilance.

Continuous use of decision support systems like AI could result in diminished motivation and focus among endoscopists when making independent decisions.
