Racial disparities in treatment and outcomes of children with type 1 diabetes.

OBJECTIVE: The aim of this study was to assess racial disparities in treatments and outcomes between Non-Hispanic black (NHB), Hispanic and Non-Hispanic white (NHW) children with type 1 diabetes (T1D). METHODS: We reviewed electronic health records of children (<18 years) attending a large, pediatric tertiary care diabetes center in the United States between October 1, 2018, and December 31, 2019. Health care utilization (appointment attendance, ED visits, hospitalizations), technology use (insulin pumps, continuous glucose monitors [CGM]) and hemoglobin A1c (HbA1c) were examined for each race/ethnicity and stratified by insurance type (private/government) as a proxy for socioeconomic status (SES). RESULTS: Of 1331 children (47% female) with a median (IQR) age of 14.2 (11.5, 16.3) years and T1D duration of 5.8 (3.8, 9) years; 1026 (77%) were NHW, 198 (15%) NHB, and 107 (8%) Hispanic. Government insurance was used by 358 (27%) children, representing 60% of NHB and 53% of Hispanic, but only 18% of NHW children. NHB children had higher HbA1c, more ED visits and hospitalizations, and were less likely to be treated with insulin pumps or CGM than NHW children (P < .001 for all). There were no racial disparities with regard to the number of appointments attended. CONCLUSIONS: Racial disparities in technology use and diabetes outcomes persist in children with T1D, regardless of insurance status. To ensure equitable care, pediatric healthcare providers should remain cognizant of racial disparities in diabetes treatment. The impact of provider and patient factors should be explored when studying the etiology of these health disparities.

Insulin Pump Use in Children with Type 1 Diabetes: Over a Decade of Disparities.

PURPOSE: Racial disparities have been shown in outcomes and treatment of children with type 1 diabetes (T1D). The purpose of this study was to examine temporal trends in insulin pump use among non-Hispanic white (NHW), non-Hispanic black (NHB) and Hispanic children attending a large urban diabetes center. . This study was a retrospective chart review of insulin pump usage by race (NHW/ NHB) in 2005, and race/ethnicity (NHW/NHB/Hispanic) in 2011-2019. Demographic data (age, sex, diabetes duration, SES) and most recent hemoglobin A1c were also abstracted in 2011-2019. RESULTS: In 2005, NHW children were twice as likely to use an insulin pump as NHB children. From 2011 to 2019, the odds ratio increased to 2.5 for NHW compared to NHB children. The odds of Hispanic children using insulin pumps were also higher than NHB. Insurance status (government versus private), a surrogate for SES, had very little influence on these trends, with NHW children consistently more likely than NHB children to be treated with insulin pumps in 2011, 2013, 2017, 2019 (p < 0.001). CONCLUSIONS: We have demonstrated that racial disparities in insulin pump use have persisted over the past 15 years, and are not determined by SES. This inequity in diabetes treatment may be playing a role in the poorer glycemic control and higher rates of diabetes complications in NHB children. PRACTICE IMPLICATIONS: Healthcare providers should be cognizant of racial and ethnic disparities in the treatment of children with T1D. Standardized treatment protocols may reduce unconscious bias in prescribing.
