Knowledge and attitude about drug pollution in pharmacy students: A questionnaire-based cross sectional study.

Introduction: The environmental impact of drugs or pharmaceuticals is an issue of growing concern. Healthcare professionals, and pharmacists in particular, are used to managing medicines, yet aspects about drug pollution are generally neglected in schools of pharmacy worldwide. Formation in this issue is essential to tackle the problem. In this study, we aimed to find out the degree of knowledge about the problem of pharmaceuticals in the environment and the attitude about the matter of pharmacy students at the University of the Basque Country.

Methods: We conducted a pilot study (186 students) using an online questionnaire available in two languages (Basque and Spanish). The attitude scale was validated for Spanish. To improve participation, a combination of indirect and direct recruitment was applied in the final study.

Results: Four hundred eighty-seven students participated in the final study (response rate: 65.8%). The final questionnaire contained a total of 25 questions: 13 (knowledge), eight (attitude), and three (opinion). The results showed that knowledge can be considered relatively poor, whereas attitude was generally positive, and students considered drug pollution to be a relevant issue in general and in pharmacy practice.

Conclusions: We believe there is an urgent need to include aspects about pharmaceuticals in the environment in pharmacy studies worldwide.
