558. Increasing Safety Net Antibiotic Prescriptions (SNAP) for Acute Otitis Media Treatment in Pediatric Urgent Care Clinics

Abstract

Background Acute otitis media (AOM) is the most common diagnosis for which antibiotics are prescribed in pediatrics. National guidelines recommend offering a safety net antibiotic prescription (SNAP) to select patients, to be filled if symptoms worsen or do not improve within 48-72 hours. However, clinicians continue to prescribe immediate antibiotics for most cases of AOM. Our goal was to increase the percentage of eligible patients diagnosed with AOM in our pediatric urgent care (PUC) clinics who are offered a SNAP from our baseline of 7.7% to 40% within nine months. Methods A multidisciplinary team of PUC clinicians, an Infectious Diseases physician, and a data analyst, used quality improvement (QI) methodology to identify barriers to offering SNAP (Figure 1). Patients without chronic ear conditions were considered eligible for SNAP if they had no or mild otalgia for < 48 hours, fever < 39oC, no otorrhea, and for patients ≤ 24 months old, if they had only unilateral AOM. We analyzed all encounters of patients ≥ 6 months old with a discharge diagnosis of AOM from three PUC clinics during baseline (October 2020 – September 2021) and study (October 2021 – March 2022) periods. Interventions included clinician education, standardized discharge instructions, electronic health record updates to improve documentation, and educational flyers for clinicians and families. Our outcome measure was the percentage of eligible encounters during which SNAP was offered. Our process measure was the percentage of AOM encounters in which SNAP eligibility was documented. Our balancing measure was the percentage of patients returning with AOM symptoms within 14 days. Results We reviewed 12,502 encounters from October 2020 through March 2022. At baseline, clinicians documented SNAP eligibility in 5.5% of AOM encounters and offered SNAP to 7.7% of eligible patients. By March 2022, clinicians documented SNAP eligibility in 58.9% of AOM encounters and offered SNAP to 40.7% of eligible patients (Figure 2). There was no change in our balancing measure. UCL: Upper control limit. LCL: Lower control limit. Conclusion Using QI methodology, we increased the percentage of eligible patients with AOM who were offered SNAP, reducing antibiotic exposure in PUC clinics. Efforts are ongoing to further improve this process. Disclosures Brian R. Lee, PhD, MPH, CDC: Grant/Research Support|Merck: Grant/Research Support.
