BackgroundChildren increasingly undergo diagnostic imaging procedures, sometimes with general anesthesia (GA). It is unknown whether the use of GA differs by race/ethnicity among children undergoing magnetic resonance imaging (MRI) scans.MethodsThis is a retrospective cohort study of GA use for pediatric patients from 0 to 21 years of age who underwent MRIs from January 1, 2004 to May 31, 2019. The study sample was stratified into 5 age groups: 0 to 1, 2 to 5, 6 to 11, 12 to 18, and 19 to 21. Analysis was performed separately for each age group.ResultsAmong 457,314 MRI patients, 29,108 (6.4%) had GA. In the adjusted regression models, Asian patients aged 0 to 1 (adjusted relative risk [aRR] [95% confidence interval {CI}] of 1.11 [1.05-1.17], P < .001) and aged 2 to 5 (aRR [95% CI], 1.04 [1.00-1.09], P = .03), Black patients aged 2 to 5 (aRR [95% CI], 1.04 [1.01-1.08], P = .02) and aged 6 to 11 (aRR [95% CI], 1.13 [1.06-1.20], P < .001), and Hispanic patients aged 0 to 1 (aRR [95% CI], 1.07 [1.03-1.12], P < .001) were more likely to receive GA for MRIs than White patients.ConclusionsAsian, Black, and Hispanic children of some ages were more likely to receive GA during MRI scans than White children in the same age group. Future research is warranted to delineate whether this phenomenon signifies disparate care for children based on their race/ethnicity.Copyright © 2023 International Anesthesia Research Society.
