An intensive anatomy by whole-body dissection elective: A longitudinal study

Area of Science:

• Medical Education
• Anatomy
• Surgical Training

Background:

• Whole body dissection was a traditional anatomy teaching method.
• Current methods often prioritize cost and time efficiency over depth.
• There is a need to evaluate the efficacy of dissection-based anatomy learning.

Purpose of the Study:

• To assess knowledge acquisition and retention from an intensive elective anatomy by whole body dissection (AWBD) course.
• To evaluate the impact of modified team-based learning (TBL) pedagogy in AWBD.
• To determine the long-term retention of anatomical knowledge gained through dissection.

Main Methods:

• A longitudinal study of six annual 8-week AWBD courses (2010-2015).
• 160 students participated, working in small groups to dissect cadavers.
• Standardized practical tests assessed anatomical knowledge pre-course, post-course, and at 1 and 7 months follow-up.

Main Results:

• Significant increase in topographical relational anatomical knowledge post-course (median score 19/20 vs 9/20 pre-course, p < 0.001).
• No significant decline in knowledge was observed 1 month or 7 months post-course.
• AWBD demonstrated effective acquisition and maintenance of 3D regional anatomical knowledge.

Conclusions:

• Intensive elective anatomy by whole body dissection (AWBD) effectively imparts and retains complex anatomical knowledge.
• AWBD is a valuable component of medical curricula, particularly for future surgeons.
• The modified TBL approach supports deep learning in anatomical dissection courses.
