2069. A Unique Approach to Outpatient Antibiotic Stewardship in Rural Southern Ohio

BACKGROUND: A five county rural community in southern Ohio was identified as having significantly higher than average rates of antibiotic use. The hospital system serving this area, Southern Ohio Medical Center (SOMC), began initial efforts in antimicrobial stewardship focusing on inpatient prescribing. However, most antimicrobial consumption occurs in the outpatient setting. Early attempts to improve antibiotic prescribing focused on only provider education and resulted in little change. Providers felt they were performing well, or their patients were more complex and prescribing the antibiotics was warranted. SOMC partnered with the state Quality Improvement Organization, HSAG, to design an intervention to address these challenges. METHODS: All outpatient and emergency room encounters with acute bronchitis and upper respiratory infection (URI) (ICD-10 codes [J00, J06.9, and J20.X]) were included in the analysis. Using criteria from a National Quality Forum measure, concomitant diagnoses were excluded to identify encounters where an associated condition may indicate the case is more complex. A 6-month baseline and two additional 6-month remeasurement periods were analyzed. Providers were given letters, peer-to-peer antimicrobial data comparison, and in-person feedback with guideline-driven recommendations for these conditions. RESULTS: Baseline analysis indicated 50% of all encounters without a coded concomitant diagnosis resulted in antibiotic prescriptions. There was a reduction in the overall rate at each remeasurement period, to 34% and then 12%. This resulted in a 76% relative improvement rate (RIR) overall at the final remeasurement period. At baseline, the highest volume setting, urgent care, had a prescribing rate of 71%. Urgent-care prescriptions reduced each remeasurement to 45% and 13%, resulting in an 81% RIR. CONCLUSION: Implementing a robust outpatient stewardship program in a rural nonacademic setting is not without unique challenges. By using peer comparison of provider performance data on prescribing habits in uncomplicated patients with URI and acute bronchitis in addition to education, the rate of appropriate antibiotic use improved.
