Decreased Outpatient Fluoroquinolone Prescribing Using a Multimodal Antimicrobial Stewardship Initiative.

ABSTRACT:

Background

Fluoroquinolones are antibiotics prescribed in the outpatient setting, though they have serious side effects. This study evaluates the impact of stewardship interventions on total and inappropriate prescribing of fluoroquinolones in outpatient settings in a large county hospital and health system.

Methods

In an effort to decrease inappropriate outpatient fluoroquinolone usage, a multimodal antimicrobial stewardship initiative was implemented in November 2016. Education regarding the risks, benefits, and appropriate uses of fluoroquinolones was provided to providers in different outpatient settings, Food and Drug Administration warnings were added to all oral fluoroquinolone orders, an outpatient order set for cystitis treatment was created, and fluoroquinolone susceptibilities were suppressed when appropriate. Charts from October 2016, 2017, and 2018 were retrospectively reviewed if the patient encounter occurred in primary care clinics, emergency departments, or urgent care centers within Parkland Health & Hospital System and a fluoroquinolone was prescribed. Inappropriate use was defined as a fluoroquinolone prescription for cystitis, bronchitis, or sinusitis in a patient without a history of Pseudomonas aeruginosa or multidrug-resistant organisms and without drug allergies that precluded use of other oral antibiotics.

Results

Total fluoroquinolone prescriptions per 1000 patient visits decreased significantly by 39% (P?P?ConclusionA multimodal stewardship initiative appears to effectively reduce both total and inappropriate outpatient fluoroquinolone prescriptions.

Project description:ObjectiveTo assess the effectiveness and acceptability of antimicrobial stewardship-focused implementation strategies on inpatient fluoroquinolones.MethodsStewardship champions at 15 hospitals were surveyed regarding the use and acceptability of strategies to improve fluoroquinolone prescribing. Antibiotic days of therapy (DOT) per 1,000 days present (DP) for sites with and without prospective audit and feedback (PAF) and/or prior approval were compared.ResultsAmong all of the sites, 60% had PAF or prior approval implemented for fluoroquinolones. Compared to sites using neither strategy (64.2 ± 34.4 DOT/DP), fluoroquinolone prescribing rates were lower for sites that employed PAF and/or prior approval (35.5 ± 9.8; P = .03) and decreased from 2017 to 2018 (P < .001). This decrease occurred without an increase in advanced-generation cephalosporins. Total antibiotic rates were 13% lower for sites with PAF and/or prior approval, but this difference did not reach statistical significance (P = .20). Sites reporting that PAF and/or prior approval were "completely" accepted had lower fluoroquinolone rates than sites where it was "moderately" accepted (34.2 ± 5.7 vs 48.7 ± 4.5; P < .01). Sites reported that clinical pathways and/or local guidelines (93%), prior approval (93%), and order forms (80%) "would" or "may" be effective in improving fluoroquinolone use. Although most sites (73%) indicated that requiring infectious disease consults would or may be effective in improving fluoroquinolones, 87% perceived implementation to be difficult.ConclusionsPAF and prior approval implementation strategies focused on fluoroquinolones were associated with significantly lower fluoroquinolone prescribing rates and nonsignificant decreases in total antibiotic use, suggesting limited evidence for class substitution. The association of acceptability of strategies with lower rates highlights the importance of culture. These results may indicate increased acceptability of implementation strategies and/or sensitivity to FDA warnings.

Project description:BackgroundFluoroquinolones increase the risk of Clostridioides difficile infection and antibiotic resistance. Hospitals often use pre-prescription approval or prospective audit and feedback to target fluoroquinolone prescribing. Whether these strategies impact aggregate fluoroquinolone use is unknown.MethodsThis study is a 48-hospital, retrospective cohort of general-care, medical patients hospitalized with pneumonia or positive urine culture between December 2015-September 2017. Hospitals were surveyed on their use of pre-prescription approval and/or prospective audit and feedback to target fluoroquinolone prescribing during hospitalization (fluoroquinolone stewardship). After controlling for hospital clustering and patient factors, aggregate (inpatient and post-discharge) fluoroquinolone (ciprofloxacin, levofloxacin, moxifloxacin) exposure was compared between hospitals with and without fluoroquinolone stewardship.ResultsThere were 11 748 patients (6820 pneumonia; 4928 positive urine culture) included at 48 hospitals. All hospitals responded to the survey: 29.2% (14/48) reported using pre-prescription approval and/or prospective audit and feedback to target fluoroquinolone prescribing. After adjustment, fluoroquinolone stewardship was associated with fewer patients receiving a fluoroquinolone (37.1% vs 48.2%; P = .01) and fewer fluoroquinolone treatment days per 1000 patients (2282 vs 3096 days/1000 patients; P = .01), driven by lower inpatient prescribing. However, most (66.6%) fluoroquinolone treatment days occurred after discharge, and hospitals with fluoroquinolone stewardship had twice as many new fluoroquinolone starts after discharge as hospitals without (15.6% vs 8.4%; P = .003).ConclusionsHospital-based stewardship interventions targeting fluoroquinolone prescribing were associated with less fluoroquinolone prescribing during hospitalization, but not at discharge. To limit aggregate fluoroquinolone exposure, stewardship programs should target both inpatient and discharge prescribing.
