Introduction: Pharmaceutical companies offer various gifts to physicians to encourage them to prescribe their products. This collaboration has some negative and positive aspects. Different countries have established guidelines to limit the collaboration and reform such relationships. This study aims to determine the attitude of Bangladeshi medical students towards pharmaceutical gifts, physician-pharmacist collaboration, and associated factors. Methods: An online cross-sectional and correlational study was conducted through email and Google-Forms among Bangladeshi medical students. A total of 435 students from different medical colleges (...) completed the questionnaires in May and June, 2016. Results: Monthly parental income was moderate among the majority of medical students. Less than 16% had a physician or pharmacist parent. Most of the students were taught about medical ethics, but 73% were not taught about the ethics of physician-pharmacist collaboration. About 85% did not have any experience of interaction with marketing representatives. Drug samples and pennotepads were the most appreciated pharmaceutical gifts. Jewelry and gifts costing more than 100 thousand were said to be the least appreciated pharmaceutical gifts. Attitudes towards drug companies and representatives were assessed by fifteen statements. Medical students had a variety of attitudes regarding its ethical justification. Attitudes were correlated with gender, parental income, physician parents, academic years, and having been taught about pharmaceutical collaboration with physicians. Conclusion and Recommendations: medical students should elaborate on ethical reasoning before accepting pharmaceutical gifts. Medical colleges and curriculums should teach them about the interaction. A national guideline may be needed. (shrink)
