PurposeImproved drug-utilization and cost outcomes achieved by a pharmacist-led antimicrobial stewardship program (ASP) are described.SummaryPharmacists may be tasked to lead ASP development and implementation with little or no support from an infectious diseases (ID) physician and other hospital personnel whose involvement on ASP teams is recommended (e.g., clinical microbiologists, infection control specialists, hospital epidemiologists). Several years ago, Intermountain Healthcare's 325-bed McKay-Dee Hospital in Utah implemented an ASP led by an antimicrobial stewardship pharmacist. In addition to reviewing patient profiles and meeting with physicians to discuss cases daily (Monday-Friday), the pharmacist was available to provide afterhours phone consultations; support was provided by an infection prevention nurse, two physician ASP champions, the pharmacy leadership, pharmacy informatics and hospital laboratory personnel, and the chief medical officer. In the program's first 33 months, the pharmacist made a total of 2,457 interventions or recommendations, with an acceptance rate of 91.8%. Comparison of selected outcomes during one-year periods before and after ASP implementation indicated substantial decreases in the utilization of four commonly used antimicrobial agents and classes (carbapenems, daptomycin, echinocandins, and levofloxacin) in the postimplementation period, with a significant decline in the average length of stay for community-acquired pneumonia (mean ± S.D., 2.69 ± 0.10 days versus 3.40 ± 0.23 days; p = 0.03). Two years after ASP implementation, annual cost savings attributed to the program were estimated at $355,000.ConclusionIn the absence of ID physician support and oversight, the pharmacist-led ASP achieved substantial reductions in antimicrobial utilization and associated expenditures.Copyright © 2015 by the American Society of Health-System Pharmacists, Inc.
