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. Survey questions were grouped into domains: perceptions of pharmacist roles (ROLES) in PH, confidence in ability to identify and address PH problems (CONF), pharmacist impact on improving PH outcomes for patients with human immunodeficiency virus (IMPACT-HIV), diabetes (IMPACT-DM), or alcoholism (IMPACT-AL), perceiving pharmacists as role models in PH (MODEL), and whether PH is beyond the scope of pharmacy practice (SCOPE). Within each domain, paired t-tests were performed on summated scores (pre- vs. post-, alpha = 0.05). Results Both surveys were completed by 271 of 336 students (80.7%). Baseline scores were lowest in the CONF and MODEL domains. The activity resulted in significant changes in 21 out of 24 survey questions. Significantly higher scores were found for domains of ROLES (+1.22), CONF (+1.60), IMPACT-HIV (+0.65), IMPACT-DM (+0.42), IMPACT-AL (+0.70), and MODEL (+1.50). Cronbach's alpha ranged from 0.73 to 0.93 for each domain. Conclusion A PH case-based learning session increased students' scores on a pre- and post-activity survey regarding PH challenges at the micro-level. The activity improved students' perceptions and confidence in providing PH interventions.
