Antimicrobial stewardship in Latin America: Past, present, and future

Implementation of antimicrobial stewardship programs (ASPs) in well-resourced countries has been associated with reductions in antibiotic-resistant infections and improved patient outcomes. Several guidance documents providing recommendations on how to structure antimicrobial stewardship activities at the national and hospital level in resource-limited settings have been published. However, few hospitals in Latin America report having a structure or resources needed for a successful ASP. Given the alarming increases in antimicrobial resistance in Latin America, better understanding of barriers to promote implementation of effective ASPs is urgently needed. We have summarized past and present antimicrobial stewardship activities in Latin American hospitals, and we describe key elements needed in future efforts to strengthen antimicrobial stewardship in the region.
