Abstract

Background Antimicrobial stewardship programs ensure antibiotic therapy is used appropriately and includes de-escalation when clinical status or culture data indicates broad-spectrum agents are no longer needed. Although the impact of infectious diseases clinical pharmacists has been well documented, there is limited research evaluating the impact of adult internal medicine clinical pharmacists on broad-spectrum antibiotic de-escalation while rounding on internal medicine teams. Objective To determine if broad-spectrum antibiotics were de-escalated more regularly and more rapidly in patients on internal medicine services with a rounding pharmacist at the bedside compared to internal medicine services without rounding pharmacists. Setting A single 700 bed academic medical center in the United States of America. Method This was a prospective observational cohort chart review. Main outcome measure The primary endpoint was appropriate broad-spectrum antibiotic de-escalation within 72 h or upon return of culture results. Result A total of 64 patients were included in this study with 39 in the pharmacist group and 25 in the no pharmacist group. De-escalation occurred in 35/39 patients on services with pharmacists and in 13/25 patients on services without pharmacists (p = 0.001). In terms of mean days of broad-spectrum antibiotic therapy, services with rounding pharmacists saw patients on Methicillin-resistant Staphylococcus aureus coverage for an average of 2.12 days of their duration of therapy compared to 2.8 days in those without pharmacists (p = 0.821). Services with rounding pharmacists saw patients on Pseudomonas aeruginosa coverage for 2 days of their length of stay compared to 3 days in those without pharmacists (0.398). Conclusion This data shows that broad-spectrum antibiotics were de-escalated more frequently on medicine services with rounding pharmacists compared to services without pharmacists.
