Abstract

Abstract: Background: An estimated 30% of all outpatient antibiotic prescriptions in the U.S. are unnecessary. Effective January 2020, The Joint Commission has implemented new core elements of performance requiring antimicrobial stewardship programs (ASP) to expand to outpatient practice settings. The purpose of this study was to determine whether pharmacist-led audit-and-feedback would improve antibiotic prescribing for urinary tract infections (UTI) and skin and soft tissue infection (SSTI) at two primary care practices. Methods: This retrospective, quasi-experimental study was conducted evaluating patients treated for UTI and SSTI at two outpatient primary care offices, one Family Medicine and the other Internal Medicine. The primary objective was to compare rates of total appropriateness of antibiotic prescribing before (Pre-ASP) versus after (Post-ASP) implementing a pharmacist-led audit-and-feedback process reviewing antibiotics prescribed for UTIs and SSTIs. Total appropriateness was defined by appropriate antibiotic selection, dose, duration, and therapy indication in accordance with institutional outpatient empiric therapy antimicrobial guidelines. Secondary objectives included comparing patient outcomes, including infection-related re-visits and Clostridioides difficile infections between groups. Results: A total of 400 patients were included in this study (Pre-ASP n=200, Post-ASP n=200) Total antibiotic appropriateness improved significantly from 27.5% to 50.5% after implementation of the audit-and-feedback process (p< 0.0001). Significant improvement was also seen for individual prescribing components including appropriate drug selection (94% vs. 98%, p=0.041), duration (57.5% vs.83.5%, p< 0.0001), and therapy indication (94% vs. 98%, p=0.041). There were no differences in patient outcomes between groups including adverse drug events, treatment failure, C.difficile infections, and infection-related re-visits or hospitalizations within 30 days. Conclusion: A pharmacist-led audit-and-feedback outpatient stewardship strategy demonstrated significant improvement in outpatient antibiotic prescribing for UTI and SSTI.
