Pathology resident education has a steep learning curve. Specimen sampling (grossing) is a procedural task, and procedural fields add video materials to their curricula to familiarize trainees with procedure(s), reduce errors, and improve patient care. Our team applied this strategy to develop original in-house sampling videos for our program.


To evaluate the effect of in-house sampling videos on resident sampling confidence.


Sampling videos covering all major organ systems (AMOS) were created for our postgraduate year 1 (PGY1) trainees. Videos were hosted on a Northwestern cloud server for on-demand access. Trainees completed 3 surveys (0, 6, 12 months) evaluating sampling confidence comparing those who used in-house videos as an educational supplement with those who did not use the videos.


Sampling confidence significantly improved at 6 and 12 months (P < .001) across AMOS and PGY levels. When compared with those who did not use in-house sampling videos, trainees who supplemented their education with in-house sampling videos had significantly higher confidence ratings across AMOS and PGY levels at the start of the study (P < .001) and at 6 months (P = .004). Sampling confidence significantly improved for PGY1 trainees at 6 and 12 months (P < .001); for PGY2 and PGY3 trainees, confidence significantly improved at 6 months (P < .001). When evaluated by organ-specific analyses, sampling and teaching confidence improved across all organ systems and, except for the gastrointestinal system, reached significance at 12 months for all PGY levels.


Sampling videos, when used as a supplement to the existing curriculum, significantly improved trainee confidence.
