Web-based pathology modules with virtual slides are effective for teaching introductory gastrointestinal pathology concepts.

ABSTRACT

Pathology interns face a steep learning curve as they transition from medical school to residency. Innovative teaching tools are needed to effectively and efficiently bridge this gap. We created four online learning modules geared toward pathology interns, for use at the beginning of the gastrointestinal pathology rotation at our institution. Our modules covered introductory esophageal, gastric, small bowel, and colonic pathology. Each module incorporated photomicrographs and annotated virtual slides, and included pre- and post-module assessment questions and a link to an anonymous survey. Twelve interns completed the modules between 9/20/2019 and 12/31/2021, including 80% of the 2020-2021 intern class. Significant improvement in performance was seen between the pre- and post-module questions for the stomach, small bowel, and colon modules (p < 0.05 for all), with a trend toward improved performance with the esophageal module. Interns rated the modules highly and indicated that they would recommend the modules to their peers. While the modules were geared toward interns, due to the coronavirus-19 pandemic we expanded access to the modules to include medical students. Medical students also found the learning modules valuable and requested more modules in the future. We conclude that online learning modules are an effective tool for teaching pathology interns and are well-received by this group. Online modules can also be seamlessly incorporated into asynchronous medical student teaching.
