Restriction-free antimicrobial stewardship initiative targeting fluoroquinolone reduction across a regional health-system

Abstract

SummaryBackgroundFluoroquinolone (FQ) antibiotics have become a target of many antimicrobial stewardship programmes. Multiple post-marketing warnings from the Food and Drug Administration caution against use of this drug class for certain infections due to risk of harmful adverse effects outweighing benefit. Commonly employed strategies to affect antibiotic prescribing can be restrictive and without improvement in overall antibiotic appropriateness or decrease in collateral damage.AimTo develop a strategy for sustainable optimization of FQ antibiotics.SettingMulti-state health-system of 14 hospitals and medical centers.MethodsThe health-system antimicrobial stewardship program identified the opportunity to improve FQ utilization. In collaboration with our data and analytics team, specific targets of FQ use in pneumonia and chronic obstructive pulmonary disease were established. Face-to-face provider education and prospective audit and feedback were the mainstays of the campaign. Enhancements to the electronic medical record to support the initiative were also implemented.FindingsThere was an overall decrease in FQ utilization by 56.9%. For pneumonia use of FQs decreased from 16.4% to 8.1% and in COPD changed from 29.6% to 9.7% over the same time period.ConclusionsA non-restrictive FQ optimization initiative based on education and feedback decreased both FQ consumption and total antibiotic use across a large multi-hospital health-system.
