A case-based learning exercise to increase students' understanding of the pharmacist's role in public health interventions for individual patients.

Introduction: The purpose of this study was to evaluate whether a public health (PH) micro-level case-based learning exercise increased pharmacy students' self-perceived understanding and confidence in their role as PH pharmacists.

Methods: Three PH micro-level case-based learning exercises in community pharmacy settings were developed and integrated into the third professional year PH course. Students enrolled in the PH course from January 2012 - May 2015 completed a pre- and post-activity survey consisting of 22 statements with Likert scale responses.
