Outcomes of the use of plastination in anatomy education: current evidence

We aimed to evaluate the quantity and quality of current evidence concerning the outcomes of use of plastinated specimens in anatomy education.

We performed a narrative literature review, searching for papers dealing with the use of plastination in anatomy education. PubMed, Scopus, ERIC, Cochrane, Web of Science and CINAHL complete electronic databases were searched. The following data were extracted: author(s), year of publication, type of study (comparative or not), number of participants, evaluation of statistical significance, educational outcomes and their level according to Kirkpatrick hierarchy.

Six studies were eligible for analysis. Five of them evaluated only students' reactions about plastination and one study also assessed their examinations results. There were four non-comparative and two comparative studies. Only a study evaluated statistical significance (p < 0.05) with higher score of perception in 2nd year undergraduate medical students, who were more familiar with plastination in comparison to 1st year students. Although the use of plastination was accompanied by positive outcomes in the majority of studies (five out of six), this method was not proved superior to traditional cadavers dissection.

The existing evidence about the outcomes of the use of plastination in anatomy education is relatively limited and lacks comparative studies with statistical significant results. Positive students' reactions were generally noted, but further research is needed to clarify if plastination could be of benefit to students' attitude and anatomy knowledge.
