2096. System-Wide Multi-Pronged Approach Leads to Successful Reduction of Fluoroquinolone Use Across a Large Health System

BACKGROUND: Overuse of fluoroquinolones has been associated with increased rates of Clostridioides difficile infections, MRSA, and resistant Gram-negative infections due to selective pressure on normal flora. In addition, the FDA has issued several safety alerts regarding systemic use of fluoroquinolone antibiotics due to concerns for serious adverse events and antimicrobial resistance. Considerable variability in the utilization of this antibiotic class across the system resulted in a system-wide initiative to reduce inappropriate prescribing. METHODS: A national initiative included the integration of system-wide approved adult criteria for use into electronic health record order sets and pharmacy clinical decision support systems. System-wide education on the initiative involved learning modules, education toolkits and webinars. Fluoroquinolone utilization rates were reported monthly to help facilities determine the success of initiatives to improve performance. RESULTS: The fluoroquinolone criteria for use were integrated into several disease-specific order sets system-wide to include: pneumonia, acute exacerbation of COPD, chronic bronchitis, sepsis, acute pyelonephritis, and skin and soft-tissue infection. The learning modules were assigned to all acute care pharmacists resulting in 1,783 completions. Education toolkits were utilized by antimicrobial stewardship teams for provider education. A significant reduction in fluoroquinolone utilization rates, defined by days of therapy (DOT) per 1000 patient-days, was seen across 94 facilities (Figure 1). This resulted in a 45.84% reduction in fluoroquinolone rates from 2017 (56.96, 95% CI 56.72, 57.21) to 2018 (30.85, 95% CI 30.66, 31.04). CONCLUSION: Developing and implementing a multi-pronged approach to maximize the effective use of fluoroquinolones can result in significant reductions in utilization across a diverse health system.
