  • Title: An interventional program to improve antibiotic use.
    Author: Feucht CL, Rice LB.
    Journal: Ann Pharmacother; 2003 May; 37(5):646-51. PubMed ID: 12708938.
    Abstract:
    BACKGROUND: Large volume and often inappropriate use of specific antimicrobial agents increase selective pressure for emergence of resistant bacteria and place strain on the pharmacy budget. OBJECTIVE: To initiate a multidisciplinary program designed to align intravenous vancomycin and fluoroquinolone prescribing practices with guidelines for appropriate use of these agents. METHODS: A multidisciplinary, prospective interventional program was implemented to encourage early discontinuation of inappropriate vancomycin and fluoroquinolone therapy and decrease inappropriate duplicative gram-negative coverage using fluoroquinolones. A computerized review was performed for patients receiving intravenous vancomycin and fluoroquinolones for 1998 in a Veterans Affairs Medical Center. In June 1999, guidelines were disseminated and an interventional program was initiated, with a monthly conference for medical residents regarding antimicrobial resistance and local hospital practices. Concurrently, a prospective review of new orders was assessed by the clinical pharmacist and interventions performed when inappropriate use occurred. RESULTS: The interventional program was successful in reducing unnecessary duplicative gram-negative coverage with intravenous fluoroquinolones by 26% (p < 0.001) from 1998 to 2001. Overall, a 43% reduction in the number of courses of intravenous fluoroquinolones was seen during these 4 years. Courses lasting >5 days were reduced by 22% (p < 0.001). Vancomycin prescriptions deemed inappropriate that were administered >5 days were reduced by 16% (p < 0.001) during the same time period. The interventions performed by the clinical pharmacist were deemed successful, with a 76% acceptance rate by providers. CONCLUSIONS: Education of physicians through monthly conferences and personal interventions resulted in an increase in appropriate empiric antibiotic use, a decrease in the duration of inappropriate use, and a decrease in duplicate gram-negative coverage.
