Introduction. Antimicrobial stewardship programmes (ASP) have proven to be effective tools for reducing the use of antimicrobials. The purpose of the study is to evaluate the effect of an ASP implantation in a medical Ward.
Material and methods. Prospective intervention study in a medical ward with a heterogeneous composition. In September 2014, an ASP based on prospective audits was implemented. Antimicrobial consumption and the length of stay and mortality in all patients admitted, as well as in the main infections present in the unit, were compared before and after two years of the ASP implementation.
Results. A total of 378 infectious episodes of 335 pa-tients were evaluated in 168 meetings. The prescriber ac-cepted 92.3% of the suggestions. The consumption of an-timicrobials reviewed was reduced from 31.3 to 17.6 DDD / 100-stays (β =-0.40, P = 0.015). The average cost per income was reduced from € 161.4 to € 123.3 (-23.6%). No differences were found in total length of stay or mortality. There were no changes in the incidence of Clostridium difficile infection or candidemia between the two periods. There were no significant differences in length of stay or mortality in total bacteremia, candidemia, and urinary tract infections caused by multiresistant bacteria.
Conclusions. The implementation of an ASP in a heterogeneous medical ward significantly reduces the use of antimicrobials in a short time horizon without adversely affecting the evolution of the patients.
