Anatomy by Whole Body Dissection as an Elective: Student Outcomes.

BACKGROUND: Anatomy education has long been considered fundamental to the medical profession. Recently, Australasian medical schools have favored prosected human material, models and medical imaging in their anatomy curriculum with only 3 medical schools offering whole-body dissection. The aim of this study was to explore the knowledge acquisition and perceptions of an elective anatomy by whole body dissection (AWBD) course for senior medical students. METHODS: In the 2017 AWBD course, 53 self-selected senior medical students carried out dissections over an 8-week period. Students were assessed via true/false questions and practical tests involving the identification of structures on anatomical images at precourse, mid-course and end-course. In addition, at completion of the course, students completed a questionnaire using a 5-point Likert scale and 2 open-ended questions. Quantitative data analysis was conducted on test scores and questionnaire data using a paired-sample t-test and descriptive statistics. Qualitative data were coded and categorised into themes. RESULTS: There was a significant improvement (p < 0.0001) in student test scores from pre-course (mean 34.1 ± 12.9%) to mid-course (mean 74.8 ± 9.4%) and end-course (mean 75.4 ± 9.8%). Analysis of the questionnaire data showed strongly favorable perceptions of the course, highlighting dissection, complemented by Structure, Clinical, Objective-Referenced, Problem-Based, Integrated and Organized (SCORPIO) teaching, frequent testing and senior surgeon supervision as beneficial teaching methods. CONCLUSIONS: Dissecting in small groups has been shown to be an effective part of anatomy learning. Our study suggests complementary teaching methods as possible augmenters to a well-structed, small group AWBD course. We have presented a framework suitable for an intensive AWBD course within medical curricula, that was valued by participants, and improved students' knowledge of anatomy.

Retention of topographical anatomical knowledge following surgeon-facilitated whole-body dissection.

BACKGROUND: Topographical anatomy has been taught to medical students by cadaver-based dissection for centuries. However, there is a void in the literature assessing the long-term retention of anatomical knowledge by medical students following teaching by whole-body dissection. The purpose of this paper was to assess both the acquisition and retention of topographical anatomical knowledge gained by medical students undertaking an elective whole-body dissection course. METHODS: This is a retrospective review of prospectively gathered data. A total of 24 students completed the elective 8-week Anatomy by Whole Body Dissection course at the University of Sydney in 2013. Surgeons and surgical trainees acted as demonstrators and anatomical knowledge was assessed on four occasions: pre, mid, end and 8 months post-course in the form of a 20-question wet specimen tag test. RESULTS: There was strong evidence of a significant difference (P < 0.001) in the students' pre-course scores (median = 8 out of 20, IQR = 6) compared with their end-course scores (median = 19 out of 20, IQR = 2). Similarly, there was a highly significant difference (P < 0.001) between students' pre-course scores and the 8-month follow-up post-course test (median = 18, IQR = 3), with a median difference of 10 points. There was no significant difference (P > 0.2) between the students' end-course assessment results and the 8 months post-course assessment indicating retention of knowledge. CONCLUSION: Surgeon-facilitated anatomical teaching to medical students by whole-body dissection significantly improves topographical anatomical knowledge which is maintained in the long term.
