Introduction: Health advocacy training is an important part of emergency medicine practice and education. There is little agreement, however, about how advocacy should be taught and evaluated in the postgraduate context, and there is no consolidated evidence-base to guide the design and implementation of post-graduate health advocacy curricula. This literature review aims to identify existing models used for teaching and evaluating advocacy training, and to integrate these findings with current best-practices in medical education to develop practical, generalizable recommendations for those involved in the design of postgraduate advocacy training programs. Methods: Ovid MEDLINE and PubMed searches combined both MeSH and non-MeSH variations on advocacy and internship and residency. Forward snowballing that incorporated grey literature searches from accreditation agencies, residency websites and reports were included. Articles were excluded if unrelated to advocacy and postgraduate medical education. Results: 507 articles were identified in the search. A total of 108 peer reviewed articles and 38 grey literature resources were included in the final analysis. Results show that many regulatory bodies and residency programs integrate advocacy training into their mission statements and curricula, but they are not prescriptive about training methods or assessment strategies. Barriers to advocacy training were identified, most notably confusion about the definition of the advocate role and a lower value placed on advocacy by trainees and educators. Common training methods included didactic modules, standardized patient encounters, and clinical exposure to vulnerable populations. Longitudinal exposure was less common but appeared the most promising, often linked to scholarly or policy objectives. Conclusion: This review indicates that postgraduate medical education advocacy curricula are largely designed in an ad-hoc fashion with little consistency across programs even within a given discipline. Longitudinal curriculum design appears to engage residents and allows for achievement of stated outcomes. Residency program directors from emergency medicine and other specialties may benefit from promising models in pediatrics, and a shared portal with access to advocacy curricula and the opportunity to exchange ideas related to curriculum design and implementation.
