Summary
Brief summary (as posted)
This study investigates whether a brief educational intervention using Blink features can improve medical students' and non-GI trainees' ability to detect colorectal cancer in static polyp images. Secondary aims include evaluating changes in specificity, confidence, and interobserver agreement, determining which Blink features support accurate detection, and examining the link between the number of features recognized and diagnostic performance. The study will recruit medical students and non-GI trainees without prior training in polyp morphology or endoscopic image interpretation, who will complete an online pre- and post-intervention image-based survey.

Arms (1)
- type
- EXPERIMENTAL
- label
- Single Arm: Blink Features Training
- description
- Medical students and non-GI trainees complete a baseline assessment of colorectal polyp images, receive a brief 2-minute educational video on Blink features, and then complete a post-intervention assessment.

- Behavioral: Blink Features Training Video
Primary outcomes (1)
- measure
- Change in sensitivity for detection of colorectal cancer in polyp images
- timeFrame
- Immediately before and after the educational intervention (within one online survey session, approximately 15-20 minutes).
- description
- Sensitivity will be calculated as the proportion of correctly identified cancerous polyps out of all cancerous polyps presented. Comparison will be made between pre-intervention and post-intervention assessments.

Inclusion Criteria: * Images of large non-pedunculated colorectal polyps (LNPCPs) obtained from patients who have provided informed consent for the anonymous use of polyp images during colonoscopy (EC-2024-200). * Medical students and non-GI trainees who have provided written informed consent to participate in the study. Exclusion Criteria: * Participants (students or non-GI trainees) with prior experience in endoscopy or polyp detection, or those who do not provide informed consent. * Images deemed to be of insufficient quality by the principal investigator. * Patients who do not provide informed consent for image use and data collection.
