Abstract

OBJECTIVE: We aimed to decrease the difference in first-line therapy (ΔFLT) for common acute respiratory infections (ARI) in pediatric urgent care clinics (PUCs) in relation to race, ethnicity, language, and insurance using quality improvement (QI) methodology. DESIGN: Retrospective cohort study of 13-month pre-intervention (April 2022-April 2023) and 17-month (May 2023-September 2024) intervention data collection. SETTING: 92 PUC sites from 9 organizations spanning 22 states. PATIENTS: Encounters of patients 6 months to 18 years of age with ARI diagnoses. METHODS: Sites created local multidisciplinary QI teams, cause-and-effect analyses, driver diagrams, and used Plan-Do-Study-Act (PDSA) cycles. We defined FLT per national guidelines. We measured ΔFLT between socioeconomic groups as our primary outcome. Balancing measure was overall rate of FLT. Logistic regression models evaluated the impact education-only PDSAs had on ΔFLT compared to PDSAs that used education plus another intervention modality (eg clinical decision support). RESULTS: We included 895,604 encounters. Despite our QI efforts, we saw no change in ΔFLT between Spanish and English-speaking patients (3.1%), Hispanic and non-Hispanic patients (1.6%), or commercial and government-insured patients (1.6%). We saw an increase in ΔFLT between Black and White patients from 3.6% to 5.8%. We observed fluctuations in overall rates of FLT over time. The impact of PDSA cycle types was variable. CONCLUSIONS: Despite local interventions to reduce differences in prescribing, we noted a widening of the ΔFLT by race. More work is needed to understand causes of these disparities and develop effective interventions that improve equitable antibiotic prescribing.
