An Interventional Program to Improve
Antibiotic Use

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.
