<p>In this study, antimicrobial stewardship team (AST) intervention was evaluated by comparing patient outcomes and consumption of broad-spectrum antibiotics [carbapenem antibiotics and tazobactam/piperacillin (TAZ/PIPC)] before and after the intervention. There was no fluctuation in the consumption rate of carbapenem, TAZ/PIPC and other antibiotics, but there was a decreased annual consumption of antibiotics after AST intervention compared to before intervention. For the carbapenems, antimicrobial use density (AUD) of meropenem (MEPM) was highest in both periods, at 20.1 and 20.4 before and after AST intervention, respectively, with no significant change after AST intervention. However, the days of therapy (DOT) for MEPM were 27.4 and 24.8 d, respectively, with a decreasing trend after AST intervention. AUD and DOT for TAZ/PIPC after AST intervention were 6.5 and 8.1 d, respectively, which were lower than the pre-intervention values. Rapid identification of the causative strain enables early de-escalation and may improve the economics of antibiotic use, but there was no difference from before to after AST intervention. Compared with before and after strain identification, the carbapenem administration rate after AST intervention was significantly lower than the pre-intervention rate (p<0.01). There was no difference in 28-day mortality and treatment period before and after AST intervention, and there were no differences in outcomes such as resolution of bacteremia, mortality, exacerbation and no change from before to after AST intervention. Based on these results, we suggest that AST intervention can reduce consumption of antibiotics without altering patient outcomes.</p>
