[Key elements in implementing adverse event notification systems in Latin American hospitals].

Objective: To develop recommendations for the design and implementation of adverse event notification systems based on the experiences of the Latin American countries.

Methods: Employing the qualitative Metaplán methodology, proposals were obtained from 17 experts on adverse event notification systems from Argentina, Brazil, Chile, Colombia, Cuba, Mexico, and Peru and three from the Pan American Health Organization. The characteristics, scope, barriers and constraints, data entry method, type of analysis, and information feedback on adverse event notification systems were reviewed and how to involve professionals in this process was discussed.
