ObjectiveThe aim of this study was to measure racial/ethnic differences in prescription filling among children prescribed with outpatient antibiotics from the emergency department (ED).MethodsThis study is a retrospective cohort study of ED visits among children (0-21 years) from January 1 to March 31, 2018, during which oral antibiotics were prescribed. We measured the proportion of filled prescriptions in aggregate and by patient race/ethnicity. We performed multivariable logistic regression to identify patient and visit-level factors associated with prescription filling. Secondarily, we measured differences in ED revisits by prescription filling.ResultsA total of 2881 participants were enrolled. A total of 66.3% (95% confidence interval, 64.5-68.0) of prescriptions were filled. Prescription filling varied by race/ethnicity; these are as follows: 77.3% non-Hispanic (NH) white, 73.5% NH black, 51.5% Hispanic, and 51.3% others (P < 0.0001). After adjustment for patient and visit-level characteristics, Hispanic children (adjusted odds ratio [aOR], 0.5 [0.3-0.9]) and children of other racial/ethnic groups (aOR, 0.5 [0.3-0.8]) had lower odds of prescription filling in comparison to NH white children. Interpreter use (aOR, 0.5 [0.4-0.6]) and uninsured status (aOR, 0.4 [0.3-0.5]) were additional independent risk factors associated with lower odds of prescription filling. There were no differences in the 72-hour revisit rates between those who filled their prescriptions and those who did not.ConclusionsA third of antibiotic prescriptions for bacterial infections in the ED are unfilled. Hispanic children and children of other racial/ethnic groups have lower rates of prescription filling compared with NH white children. Interpreter use and uninsured status also have lower rates of prescription filling. Barriers to prescription filling should be explored further to help reduce racial and ethnic disparities in the provision of health care.Copyright © 2020 Wolters Kluwer Health, Inc.
