title: A narrative review of undergraduate peer-based healthcare ethics teaching.
abstract: OBJECTIVE
  This study explores the literature in establishing the value of undergraduate peer-based healthcare ethics teaching as an educational methodology.
  
  
  METHODS
  A narrative review of the literature concerning peer-based ethics teaching was conducted. MEDLINE, EMBASE, CINAHL, SCOPUS databases, and the Cochrane Library, were systematically searched for studies of peer-based ethics or professionalism teaching. Selected studies related peer-based teaching to ethics education outcomes.
  
  
  RESULTS
  Ten publications were identified. Selected studies were varied in their chosen intervention methodology and analysis. Collectively, the identified studies suggest peer-based ethics education is an effective and valued educational methodology in training healthcare professionals. One paper suggests peer-based ethics teaching has advantages over traditional didactic methods. Peer-based ethics teaching also receives positive feedback from student participants. However, the limited literature base demonstrates a clear need for more evaluation of this pedagogy.
  
  
  CONCLUSIONS
  The current literature base suggests that undergraduate peer based healthcare ethics teaching is valuable in terms of efficacy and student satisfaction. We conclude that the medical community should invest in further study in order to capitalise upon the potential of peer-based ethics teaching in undergraduate healthcare education.
