A critical look to community wisdom: Applying the World Cafe method to health promotion and prevention

Patient experiences and ideas are key components for improving health promotion and prevention. Engaging patients and other stakeholders in sharing their practices and ideas is nowadays crucial to increase the legitimacy, credibility, and acceptability of the decisions in these fields, by fostering community wisdom. The World Cafe is a participatory method suitable to involve a large number of actors to propose creative solutions based on their different knowledge and experiences. However, the diffusion of this approach is not uniform in the various countries and health topics. This review summarises the specific topic, the study design, the number and the characteristics of participants, as well as the main findings and the purpose of the studies regarding the application of this method to health promotion and prevention. Among other results, it was found that the World Cafe is an appreciated, inspiring, and flexible participatory process often used in association with one or more other methods, to explore emergent themes or topics, to collect best practices or suggestions, to generate improvements or recommendations, and to define priorities for the implementation of projects or research agendas. The results highlight the potentiality of the World Cafe whenever an issue is not well defined and needs to be explored through deep and several insights. The method allows the exploitation of creativity and collective wisdom when qualitative and in-dept results-more than quantitative and statistically rigorous ones-are appropriate.
