Impact of a syndrome-based stewardship intervention on antipseudomonal beta-lactam use, antimicrobial resistance, C. difficile rates, and cost in a safety-net community hospital

Abstract

Abstract Broad-spectrum antimicrobials are commonly used without indication and contribute to antimicrobial resistance (AMR). We implemented a syndrome-based stewardship intervention in a community hospital that targeted common infectious syndromes and antipseudomonal beta-lactam (APBL) use. Our intervention successfully reduced AMR, C. difficile rates, use of APBLs, and cost.
