Impact of the pharmacist on a multidisciplinary team in an antimicrobial stewardship program: a quasi-experimental...

Antimicrobial stewardship programs (ASP) have been implemented to promote rational use of antimicrobial drugs. Multidisciplinary teams are needed to form effective committees.

Assess the impact of ASP, with and without the presence of a pharmacist, in a cardiology hospital in Brazil.

The program started with an infectious disease (ID) physician, and after 22 months, a pharmacist started to work in the ASP team. We present data related to: stage 1-before the program implementation; stage 2-with the ID physician; and stage 3 with the inclusion of a pharmacist. Analysis was made by segmented regression of time series.

After the start of ASP there was a significant reduction of consumption of all antimicrobials. The pharmacist contributed to the significant reduction in consumption of fluoroquinolones, clindamycin and ampicillin/sulbactam and in increase in total cephalosporins use in stage 3. Adherence rate to the ASP team recommendations was 64.1%. There was a significant reduction of 69% in hospital antibiotics costs.

A non-expensive ASP in a limited resource country resulted in reductions in antimicrobial consumption and costs. The multidisciplinary team contributed to maximize the impact of interventions.
