- Administrative intervention involving sharing vancomycin use data with chiefs of clinical programs with high levels of inappropriate use and revising of preprinted orders for perioperative abx prophylaxis (11/21/95-1/22/96).
- Educational intervention aimed at prescribing clinicians discussing appropriate use of vanco and hospital data on vre (5/7/96-6/18/96).
|Following administrative intervention, inappropriate vancomycin use decreased by 30%. Following educational intervention, inappropriate prescribing rate increased from 40 to 50%; however, comparing those who received education vs. not revealed 32% inappropriate orders compared to 68% inappropriate orders respectively (baseline 70%). Overall, vancomycin usage decreased from 6200g per year to 5000g per year during the study period.
