AI Article Synopsis

  • A study evaluated the effectiveness of ChatGPT in answering questions about colorectal cancer (CRC) screening to improve patient awareness and adherence to screening programs.
  • 15 CRC screening questions were assessed by experts and patients, focusing on accuracy, completeness, and comprehensibility.
  • ChatGPT performed well, especially with patients, but highlighted the need for further training to align its responses with scientific evidence and guidelines.

Article Abstract

Background:  This study aimed to evaluate the effectiveness of ChatGPT (Chat Generative Pretrained Transformer) in answering patients' questions about colorectal cancer (CRC) screening, with the ultimate goal of enhancing patients' awareness and adherence to national screening programs.

Methods:  15 questions on CRC screening were posed to ChatGPT4. The answers were rated by 20 gastroenterology experts and 20 nonexperts in three domains (accuracy, completeness, and comprehensibility), and by 100 patients in three dichotomic domains (completeness, comprehensibility, and trustability).

Results:  According to expert rating, the mean (SD) accuracy score was 4.8 (1.1), on a scale ranging from 1 to 6. The mean (SD) scores for completeness and comprehensibility were 2.1 (0.7) and 2.8 (0.4), respectively, on scales ranging from 1 to 3. Overall, the mean (SD) accuracy (4.8 [1.1] vs. 5.6 [0.7];  < 0.001) and completeness scores (2.1 [0.7] vs. 2.7 [0.4];  < 0.001) were significantly lower for the experts than for the nonexperts, while comprehensibility was comparable among the two groups (2.8 [0.4] vs. 2.8 [0.3];  = 0.55). Patients rated all questions as complete, comprehensible, and trustable in between 97 % and 100 % of cases.

Conclusions:  ChatGPT shows good performance, with the potential to enhance awareness about CRC and improve screening outcomes. Generative language systems may be further improved after proper training in accordance with scientific evidence and current guidelines.

In this study, we investigated age-related changes in clinical laboratory data and their association with mortality in dogs from the Golden Retriever Lifetime Study. By analyzing complete blood count (CBC) and biochemistry data from 2'412 Golden Retrievers over 16,678 visits, we observed significant changes during the first 2 years of life and throughout aging. Based on these observations, we developed a biological aging clock using a LASSO model to predict age based on blood markers, achieving an accuracy of R = 0.
