Abstract

The implementation of antimicrobial stewardship programs (ASPs) is a promising strategy to help address the problem of antimicrobial resistance. We sought to determine the efficacy of ASPs and their effect on clinical and economic parameters. We searched PubMed, EMBASE, and Google Scholar looking for studies on the efficacy of ASPs in hospitals. Based on 26 studies (extracted from 24,917 citations) with pre- and postimplementation periods from 6 months to 3 years, the pooled percentage change of total antimicrobial consumption after the implementation of ASPs was -19.1% (95% confidence interval [CI] = -30.1 to -7.5), and the use of restricted antimicrobial agents decreased by -26.6% (95% CI = -52.3 to -0.8). Interestingly, in intensive care units, the decrease in antimicrobial consumption was -39.5% (95% CI = -72.5 to -6.4). The use of broad-spectrum antibiotics (-18.5% [95% CI = -32 to -5.0] for carbapenems and -14.7% [95% CI = -27.7 to -1.7] for glycopeptides), the overall antimicrobial cost (-33.9% [95% CI = -42.0 to -25.9]), and the hospital length of stay (-8.9% [95% CI = -12.8 to -5]) decreased. Among hospital pathogens, the implementation of ASPs was associated with a decrease in infections due to methicillin-resistant Staphylococcus aureus (risk difference [RD] = -0.017 [95% CI = -0.029 to -0.005]), imipenem-resistant Pseudomonas aeruginosa (RD = -0.079 [95% CI = -0.114 to -0.040]), and extended-spectrum beta-lactamase Klebsiella spp. (RD = -0.104 [95% CI = -0.153 to…
