This study analyzes how the Latin American Journal of Nursing contributed to the integration of nurses in Brazil and Latin America and provided foundations for their professional actions. The research methodology is based on the knowledge management model called "Knowledge Capitals", developed by the CRIE (Business Intelligence Reference Center), which focuses on subscriber Relationship Capital. Data were collected from the Journal's subscriber database and by means of an electronic questionnaire sent to subscribers ranked as "private persons" and those with an electronic address. It was evidenced that the Journal's role is inexpressive in Latin America, with a merely satisfactory penetration in Brazil. The respondents confirmed the Journal's contribution to the foundation of professional nursing actions.
