[Prevention and control of antimicrobial stewardship: a review of evidenceGestión de las intervenciones en materia de prevención y control de la resistencia a los antimicrobianos en los hospitales: revisión de la evidencia].

objectiveTo identify effective interventions to manage antimicrobial resistance in hospital settings and potential barriers to their implementation.

methodA synthesis of evidence for health policy was performed using SUPPORT tools. Literature searches were performed in November and December 2018 in 14 databases. A face-to-face deliberative dialogue workshop to identify implementation barriers was performed with 23 participants (manager, researchers, and health care professionals) and 14 listeners divided into three groups. Researchers with experience in deliberative dialogue acted as facilitators.

resultsTwenty-seven systematic reviews focusing on antimicrobial stewardship using combined or individual strategies were identified. The interventions included education, electronic systems, use of biomarkers, and several strategies of antimicrobial management. The main barriers to the implementation of interventions, identified in the literature and deliberative dialogue workshop, were poor infrastructure and insufficient human resources, patient complaints regarding the treatment received, cultural differences within the multidisciplinary team, work overload, and lack of financing/planning.

conclusionMost of the strategies identified were effective for antimicrobial stewardship in hospital settings. The reliability of results may be strengthened with the performance of additional research of higher methodological quality.
