Students as patients: A systematic review of peer simulation in health care professional education.

Students were positive about peer simulation, but there has been limited evaluation of learning outcome attainment. Significant heterogeneity was observed; studies were diverse in design, outcome measures and the training provided for peer patients. Peer simulation positively influences student communication and development of patient empathy and offers an alternative to learning with SPs. Further rigorous research is required to understand the impact of peer simulation for a broader range of learning outcomes and to confirm the impact of this developing educational approach.
