217. Bang for the Buck: Lessons Learned from An Ambulatory Stewardship Pilot to Reduce Excess Antibiotic Prescribing for Adult Upper Respiratory Infections
Session: Poster Abstract Session: Antimicrobial Stewardship: Interventions to Improve Outcomes
Thursday, October 4, 2018
Room: S Poster Hall
Background: Upper respiratory infections (URIs) are a source of unnecessary antibiotic use in the US1. To address antibiotic overuse in our clinics, we participated in a multi-phase stewardship collaborative established by the United Hospital Fund. We aimed to pilot stewardship policies for adult URIs at the Montefiore Medical Group (MMG) practices in Bronx, NY.

Methods: Phase 1: evaluation of provider use of ICD-10 codes for URIs generally not requiring antibiotics at target sites (TS) with random chart abstraction validation. Phase 2: implementation of stewardship interventions (Table 1). Prescribing patterns were evaluated using electronic health record data at the end of Phase 2 comparing TS (n=6; 2 resident clinics, 4 non-resident clinics) to the prior year and to non-target sites (NTS) (n=13).

Results: There were 6819 visits of interest from October 2017 to February 2018 within MMG. Top three codes utilized are shown in Figure 1. TS prescribing declined post-intervention and compared to NTS (Table 2). Non-resident TS participated in 4 interventions, and resident TS were involved in 2-3. Macrolides were the most utilized antibiotic class (Figure 2).

Conclusion: We attribute the decline in prescribing at TS to the collective impact of our stewardship activities. Stewardship team driven interventions had better uptake than provider-driven initiatives. We plan to continue activities with the highest uptake and feasibility. Long-term goals include development and integration of stewardship metrics into our outpatient quality structure.
