Objectives: Traditional didactic lectures are the mainstay of teaching for graduate medical education, although this method may not be the most effective way to transmit information. We created an active learning curriculum for Brigham and Women’s Hospital (BWH) gastroenterology fellows to maximize learning. We evaluated whether this new curriculum improved perceived knowledge acquisition and knowledge base. In addition, our study assessed whether coaching faculty members in specific methods to enhance active learning improved their perceived teaching and presentation skills. Methods: We compared the Gastroenterology Training Exam (GTE) scores before and after the implementation of this curriculum to assess whether an improved knowledge base was documented. In addition, fellows and faculty members were asked to complete anonymous evaluations regarding their learning and teaching experiences. Results: Fifteen fellows were invited to 12 lectures over a 2-year period. GTE scores improved in the areas of stomach (p<0.001), general gastroenterology (p=0.005), esophagus (p<0.001), and small bowel (p=0.001), and the total score (p=0.001) between pre- and postimplementation of the active learning curriculum. Scores in hepatology, as well as biliary and pancreatic study, showed a trend toward improvement (p>0.05). All fellows believed the lectures were helpful, felt more prepared to take the GTE, and preferred the interactive format to traditional didactic lectures. All lecturers agreed that they acquired new teaching skills, improved teaching and presentation skills, and learned new tools that could help them teach better in the future. Conclusion: An active learning curriculum is preferred by GI fellows and may be helpful for improving transmission of information in any specialty in medical education. Individualized faculty coaching sessions demonstrating new ways to transmit information may be important for an individual faculty member’s teaching excellence.

Purpose To assess whether differences in frequency and phenotype of APC and MUTYH mutations exist among racially/ethnically diverse populations. Methods: 6169 individuals with personal and/or family history of colorectal cancer (CRC) and polyps were studied. APC testing involved full sequencing/large rearrangement analysis (FS/LRA); MUTYH involved “panel testing” (for Y165C, G382D mutations), or FS/LRA, performed by Myriad Genetics, a commercial laboratory. Subjects were identified as Caucasian, Asian, African American (AA), or Other. Statistical tests included Chi-Square, Fisher’s Exact, ANOVA and z-approximation. Results: 17.5% had pathogenic APC mutations. 4.8% were biallelic MUTYH carriers. 18% were non-Caucasian with >100 adenomas and younger ages of adenoma or CRC diagnosis (p<0.0001) than Caucasians. The overall APC mutation rate was higher in Asians, AAs and Others compared to Caucasians (25.2%, 30.9%, 24%, 15.5%;p<0.0001) but similar in all groups when adjusted for polyp burden. More MUTYH biallelic carriers were Caucasian or Other than Asian or AA (5%, 7%, 2.7%, 0.3%;p<0.0001). Among Caucasians, 5% were biallelic carriers identified by panel testing versus 2% by sequencing/LRA (p=0.002). Among non-Caucasians, 3% undergoing panel testing were biallelic carriers versus 10% identified by sequencing/LRA(p<0.0002). Conclusion: Non-Caucasians undergo genetic testing at more advanced stages of polyposis and/or younger ages of CRC/polyp diagnosis. Restricted MUTYH analysis may miss significant numbers of biallelic carriers, particularly in non-Caucasians.
