Antibiotic stewardship

Abstract

The spread of antimicrobial resistance (AMR) is one of the greatest threats to global health and causes very many deaths. Also in the context of sepsis-the severest complication of certain infectious diseases-does AMR play arole. Wise use of anti-infectives and application of antibiotic stewardship (AMS) principles can reduce the spread of AMR and improve the quality of management of patients with infectious diseases. Correct use of anti-infective agents includes the correct diagnostic approach and documentation of the (suspected) diagnosis, guideline-conform diagnostic workup and treatment selection, re-evaluation and tailoring during the course of treatment, afocus on treatment de-escalation depending on clinical response and microbiology results, dose optimization, and, if possible, conversion to oral therapy, and early termination of treatment if the suspected diagnosis is not confirmed. Particularly adherence to the guideline-conform treatment duration can reduce unnecessary use of anti-infectives. Prevention of infections via adherence to vaccination recommendations also contributes to areduction in the use of anti-infectives. Interdisciplinary collaboration with infectious diseases and AMS specialists, as recommended for sepsis, also improves treatment quality and patient outcomes. Particularly for complex infections such as endocarditis cases should be discussed in multidisciplinary teams including specialists in infectious diseases. In this manner, decisive steps against the spread of AMR and towards maintenance of the efficacy of available anti-infective drugs can be taken.
