TUESDAY, May 31, 2022 (HealthDay News) — A novel smartphone application can accurately determine Bristol Stool Scale (BSS) and other visual stool characteristics, according to a study recently published in the American Journal of Gastroenterology<\/em> and presented at the 2022 Digestive Disease Week, held from May 21 to 24 in San Diego.<\/p>\n Mark Pimentel, M.D., from Cedars-Sinai in Los Angeles, and colleagues evaluated the accuracy of a novel smartphone application that uses trained artificial intelligence to assess stool characteristics.<\/p>\n The researchers found that in the validation phase, there was good agreement between two experts and AI characterizations for BSS, stool consistency, edge fuzziness, fragmentation, and volume. Compared with self-reports from study participants with diarrhea-predominant irritable bowel syndrome, AI outperformed for categorizing daily average BSS scores as constipation, normal, or diarrhea. Agreement between AI and self-reported BSS scores in the implementation phase was moderate. For diarrhea severity scores, AI stool characterization was found to correlate better than participant reports.<\/p>\n “The artificial intelligence tool removes the subjective description that can be part of a patient’s description of their bowel specimens,” a coauthor said in a statement. “In addition to improving a physician’s ability to assess their patients’ digestive health, this app could be advantageous for clinical trials by reducing the variability of stool outcome measures.”<\/p>\n One author is an employee and board member of Dieta Health.<\/strong><\/p>\n Abstract\/Full Text (subscription or payment may be required)<\/a><\/p>\n
