Decreased antimicrobial resistance and defined daily doses after implementation of a clinical culture-guided antimicrobial stewardship program in a local hospital
2017
Abstract Background We aimed to report the implementation of an antimicrobial stewardship program (ASP) guided by clinically significant cultures in a hospital to assess its pharmaceutical, microbiological, financial, and outcome effects. Methods A 3-year cohort study of an antimicrobial restriction policy implementation was performed. The ASP with culture-guided de-escalation of antibiotics was instituted in a local hospital since January 1, 2012. The cost of antimicrobials, defined daily dose (DDD), susceptibility to antimicrobials, and outcome of all admitted patients were calculated and evaluated before and after the ASP implementation. Results Average monthly length of stay of admitted patients decreased from 7.8 ± 0.5 days in 2011 to 6.9 ± 0.3 days in 2013 ( p p p = 0.013), Gram-negative bacteria ( p p Conclusions The ASP with a culture-guided de-escalation of antibiotics successfully reduced length of stay, mortality, the cost of antimicrobials, DDDs, and antimicrobial resistance rate, and that is highly recommended for local hospitals.
