Objectives. To determine whether a peer-to-peer education program was an expedient and effective approach to improve knowledge and promote interprofessional communication and collaboration. Design. Trained pharmacy students taught nursing students, medical students, and medical residents about the Medicare Part D prescription drug benefit (Part D), in 1-to 2-hour lectures. Assessment. Learners completed a survey instrument to assess the effectiveness of the presentation and their attitudes toward the peer-to-peer instructional format. Learners strongly or somewhat agreed that the peer-to-peer format was effective in providing Part D education (99%) and promoted interprofessional collaboration (100%). Qualitative data highlighted the program's clinical relevance, value in promoting interprofessional collaboration, and influence on changing views about the roles and contributions of pharmacists. Conclusion. The Part D peer educator program is an innovative way to disseminate contemporary health policy information rapidly, while fostering interprofessional collaboration
