Patients with type 2 diabetes who prefer non-English languages are significantly less likely to receive prescriptions for continuous glucose monitors (CGMs), according to a study of over 69,000 adults in a large U.S. health system. Despite being more likely to use insulin and have uncontrolled diabetes, only 7.4% of patients with non-English language preference (NELP) had a CGM prescription, compared to 12.7% of English-preferring patients.
After adjusting for age, sex, race, insurance, and clinical factors, the disparity persisted. Patients with NELP had 4.1% lower adjusted probability of receiving a CGM. Among insulin users and those with poorly controlled diabetes, the gap remained wide—suggesting that language, not just medical need, influences access.
Lead author Dr. Jorge A. Rodriguez and colleagues found that patients with NELP were also less likely to see endocrinologists, despite having more complex care needs. Spanish speakers made up over 60% of the NELP group, but there was no significant difference in CGM access between Spanish and non-Spanish speakers, indicating that the disparity spans multiple language groups.
The study raises concerns about how language preference may shape clinician decision-making and access to newer diabetes technologies. As CGMs become more common, the authors urge health systems to identify and address barriers to equitable adoption.
