Background: Data from community antimicrobial stewardship programs (ASPs) are limited. We describe clinical and economic outcomes from the first year of our hospital's ASP. Methods: The ASP team comprised 2 infectious disease physicians and 3 intensive care unit pharmacists. The team prospectively audited the new starts and weekly use of 8 target antimicrobials: aztreonam, caspofungin, daptomycin, ertapenem, linezolid, meropenem, tigecycline, and voriconazole. Using administrative data, outcomes from the first year of the program, including death within 30 days of hospitalization, readmission within 30 days of discharge, and development of Clostridium difficile infection (CDI), were compared with outcomes from a similar period before institution of the program. Results: A total of 510 antimicrobial orders were reviewed, of which 323 (63%) were appropriate, 94 (18%) prompted deescalation, 61 (12%) were denied, and 27 (5%) led to formal consultation with an infectious disease physician. On multivariate analysis, implementation of the ASP was associated with an approximate 50% reduction in the odds of developing CDI (odds ratio, 0.46; 95% confidence interval, 0.25-0.82). The ASP was not associated with decreased mortality at 30 days after discharge or readmission rate. The antimicrobial cost per patient-day decreased by 13.3%, from $10.16 to $8.81. The antimicrobial budget decreased by 15.2%, resulting in a total savings of $228,911. There was a 25.4% decrease in defined daily doses of the target antimicrobials. Conclusions: Implementation of the ASP was associated with significant reductions in CDI rate, antimicrobial use, and pharmacy costs.
