- Abstract
Background To identify areas for improved antibiotic use, we developed and pilot-tested visualization tools to quantify antibiotic use at 8 VA facilities. These tools allow a facility to review its patterns of total use, and use by antibiotic class, compared with patterns of use at VA facilities with similar (or user-selected) complexity levels. Methods Antibiotic stewards from 8 VA facilities participated in iterative report development and implementation, with the final product consisting of two components: an interactive web-based antibiotic dashboard and a standardized antibiotic usage report updated at user-selected intervals. Stewards also participated in monthly learning collaboratives. The percent change in average monthly antimicrobial use (all antibiotics; anti-methicillin-resistant S. aureus agents (anti-MRSA); and broad-spectrum agents predominantly used for hospital-onset/multi-drug-resistant organisms (anti-MDRO)) was analyzed using a pre-post (January 2014–January 2016 vs. July 2016–January 2018) with un-involved controls (all other inpatient VA facilities, n = 132) design modeled using Generalized Estimation Equations segmented regression. Results Intervention sites had a 2.1% decrease (95% CI = [−5.7%,1.6%]) in all antibiotic use pre-post-intervention, vs. a 2.5% increase (95% CI = [0.8%, 4.1%]) in nonintervention sites (P = 0.025 for difference). Anti-MRSA antibiotic use decreased 11.3% (95% CI = [−16.0%,−6.3%]) at intervention sites vs. a 6.6% decrease (95% CI=[−9.1%, −3.9%]) at nonintervention sites (P = 0.092 for difference). Anti-MDRO antibiotic use decreased 3.4% (95% CI = [−8.2%,1.7%]) at intervention sites vs. a 3.6% increase (95% CI = [0.8%,6.5%]) at nonintervention sites (P = 0.018 for difference) (Figure 1). Examples of graphs include overall antibacterial use (Figure 2), and usage of broad-spectrum Gram-negative therapy (Figure 3) in intensive care units. Conclusion The use of data visualization tools use and participation in monthly learning collaboratives by antimicrobial stewards in a pilot implementation project at eight VA facilities was associated with decreases in antimicrobial use relative to uninvolved sites.
