149 A Mixed Methods Analysis of Disparities in the Management of Low-Risk Febrile Infants

OBJECTIVES/GOALS: Febrile infants are a model population for exploring communication, implicit bias, and health disparities in the pediatric emergency department. Using mixed methods, we performed an in-depth analysis of disparities and physician-parent communication, a potentially modifiable driver of inequities. METHODS/STUDY POPULATION: We performed a multicenter cross-sectional study of febrile infants with low-risk for invasive bacterial infection evaluated between 2018-19 across 32 institutions. We performed logistic regression to assess the association between 1) race and ethnicity (Non-Hispanic White [NHW], Non-Hispanic Black [NHB], Hispanic [H], Other Race and/or Ethnicity [O]) and 2) limited English proficiency (LEP) with the standard of care, discharge without lumbar puncture and without antibiotics. We concurrently performed in-depth semi-structured interviews with physicians to explore physician–parent communication and implicit bias in the management decisions for febrile infants. RESULTS/ANTICIPATED RESULTS: Of 3629 low-risk febrile infants, 74.2% received standard of care. NHB, compared to NHW, infants were more likely to receive standard of care (aOR 1.3 [95% CI 1.0-1.7]; aOR H: 1.1 [95% CI 0.9-1.4]; aOR O: 1.0 [95%CI 0.8-1.4]). There was no association between LEP and standard of care (aOR 0.8 [0.61–1.1]). When accounting for documented use of professional interpretation, families with LEP without documented professional interpretation were less likely than families without LEP to receive standard of care (aOR 0.6 [95% CI 0.4–0.9]). Thematic analysis of 13 physician interviews is expected to elucidate aspects of the physician-parent interaction that influence management decisions. DISCUSSION/SIGNIFICANCE: Infant race, ethnicity, and use of professional interpretation, are associated with the management of low-risk febrile infants. Physician behaviors that are influenced by the physician-parent interaction may represent modifiable targets for future interventions to promote health equity.
