A recent study published in The Lancet has raised concerns about the impact of routine artificial intelligence (AI) assistance on the diagnostic skills of health professionals performing colonoscopies. The observational study, conducted across four hospitals in Poland and involving over 1,400 colonoscopies, found that endoscopists who regularly used AI tools to detect precancerous growths experienced a decline in their unaided ability to identify adenomas after the AI assistance was removed. Specifically, the detection rate of precancerous polyps dropped by approximately 20%, from 28.4% to 22.4%, compared to their performance before AI introduction. Researchers described this as the first documented evidence of a potential "deskilling" effect caused by clinical AI. While AI tools initially improved polyp detection rates, the study suggests that over-reliance on AI may degrade physicians' skills, attention, and responsibility in clinical practice. The findings have prompted discussions about the balance between leveraging AI benefits and maintaining critical diagnostic capabilities among healthcare providers.
