Accuracy of pharmacy student self-assessment of a single sterile compounding technique following didactic training.

INTRODUCTION

The primary objective was to determine pharmacy students' ability to self-assess sterile compounding technique in a single evaluation three semesters after training in the curriculum.

METHODS

School of pharmacy (SOP) students were trained and assessed on sterile compounding technique during their second year of school, with no additional formal assessments provided later in the curriculum. From 2016 to 2018, 262 students were asked to compound a simulated sterile product in their third year of pharmacy school and self-evaluate their technique, which was compared to an instructor evaluation with both people using the same rubric.

RESULTS

Two thresholds were used to define successful assessment: strict (ability to detect ideal technique) and lenient (ability to detect harmful technique). The average match rate was 70.2% and 87.6% in the strict and lenient analyses, respectively, with outcomes varying between categories. In the product preparation and inspecting product categories, students who disagreed with assessors tended to misidentify their incorrect technique as correct.

CONCLUSIONS

Pharmacy students who assessed themselves on sterile compounding technique three semesters after formal sterile compounding training were able to accurately self-assess in most cases, but when disagreeing with an assessor, commonly identified their incorrect technique as correct. Most students demonstrated the ability to self-assess sterile compounding technique and are prepared to assess their own sterile compounding in practice. SOPs could consider whether sterile compounding training coupled with self-assessment throughout the curriculum would be beneficial to further improve students' sterile compounding ability and accuracy of self-assessment.
