1107. Impact of Routine Education and Data Feedback on the Durability of an Antimicrobial Stewardship Intervention for Outpatient Urinary Tract Infections

BACKGROUND: Achieving lasting, sustainable effects in outpatient AS interventions has been a challenge for many programs. Our group observed an initial benefit of an outpatient AS intervention focused on diagnosis and management of urinary tract infections (UTIs). However, prescribing habits trended back toward baseline over time. This study aimed to evaluate the impact of routine education and comparative data feedback on the durability of an outpatient AS intervention for UTIs. METHODS: We conducted a prospective quasi-experimental study at one primary care (PC) and one urgent care (UC) clinic to evaluate the durability of an outpatient AS intervention implemented in August 2017 and November 2017, respectively. Clinicians who treated adult patients with a diagnosis of acute UTI at either clinic participated in the study. The initial intervention (phase 1) included development of clinic-specific antibiograms and UTI diagnosis and treatment guidelines. Approximately 12 months after the initial intervention, routine education along with clinic- and comparative provider-specific feedback reports were emailed to clinicians at regular intervals (phase 2). The primary outcome was percent of encounters in which first- or second-line antibiotics were prescribed. Pre- and post-intervention phase and trend changes were assessed using an interrupted time-series approach. RESULTS: Data were collected on 792 and 3,720 UTI encounters at PC and UC, respectively. In the 12 months after the initial intervention, rates of guideline concordance were 73% at PC and 57% at UC (Figures 1 and 2). After routine data feedback was provided for approximately 7 months at PC and 5 months at UC, rates of guideline concordance remained relatively stable at 75% for PC and 61% at UC. An initial 37% relative reduction in fluoroquinolone (FQ) use was observed during phase 1 which was further reduced by an additional 18% during phase 2. CONCLUSION: Routine provision of clinic-specific feedback and peer comparisons sustained rates of guideline-concordant prescribing at two outpatient clinics. This intervention required significant resources for data analysis and delivery, but it was successful in decreasing rates of FQ prescribing and maintaining clinician engagement.
