Background: The evaluation of febrile infants ≤60 days of age is often guided by established protocols. However, structural racism and physicians' implicit bias may affect how such clinical guidelines are applied.
Objective: To determine the association between self-identified race, insurance type, ZIP code-based median household income (MHI) and receiving a guideline-concordant lumbar puncture (GCLP) in febrile infants.
Methods: This was a 3-year retrospective cross-sectional study of all febrile infants ≤60 days old presenting to a children's hospital from 2015 to 2017. GCLP was defined as obtaining or appropriately not obtaining a lumbar puncture as defined by the hospital's clinical practice guideline, which recommended performing a lumbar puncture for all febrile infants ≤60 days of age unless an infant was >28 days of age and had respiratory syncytial virus-positive bronchiolitis. Univariate analyses were used to identify variables associated with receiving a GCLP. Variables with a P < .1 were included in a multivariate logistic regression with race, MHI, and insurance type.
Results: We included 965 infants. Age (adjusted odds ratio, 0.95; 95% confidence interval, 0.94-0.97) and temperature on arrival (adjusted odds ratio, 1.36; 95% confidence interval, 1.04-1.78) were significantly associated with receipt of a GCLP. Self-identified race, insurance type, and MHI were not associated with receiving a GCLP.
Conclusion: Receipt of a GCLP was not associated with race, MHI, or insurance type. As recent national guidelines change to increase shared decision-making, physician awareness and ongoing assessment of the role of factors such as race and socioeconomic status in the clinical evaluation and outcomes of febrile infants will be critical.
