Language barriers significantly impede diabetes care for patients with limited English proficiency (LEP), leading to poorer health outcomes and reduced access to essential tools. In 2024, U.S. health centers served over 8.9 million patients with LEP, accounting for 27.72% of those with a known language — a noticeable increase from 24.37% in 2020. Furthermore, more than 3.1 million diabetes patients were identified within these centers this year, highlighting the pressing need for language-sensitive care. According to HelloGlobo Blog, LEP patients have lower odds of maintaining ideal blood sugar levels, reflecting the systemic challenges in managing diabetes effectively across language divides.

The disparities go beyond blood sugar management. LEP patients are less frequently prescribed continuous glucose monitors (CGMs) — only 7.4% as compared to 12.7% of English-preferring patients. This gap illuminates the broader issue of accessibility to newer diabetes management technologies. The literature supports these findings; a 2020 study showed LEP patients had a 17% lower likelihood of keeping their A1c levels under control, up from 15% in 2019. Notably, inadequacies in communication exacerbate these outcomes, with 91.8% of prescribers failing to inform patients about the option for translated medication labels. Such oversights contribute to a larger picture where nearly 70% of healthcare providers doubt whether patients understand their written instructions accurately.

Interventions aimed at bridging language gaps can significantly improve diabetes care outcomes. As evidenced by a study from March 2017, Latino adults with LEP improved their A1c outcomes by 10% after consulting Spanish-speaking physicians. This intervention stresses the importance of linguistically tailored care in diabetes management. The HelloGlobo Blog advocates for basic, yet impactful solutions, such as scripting pharmacy checkouts to inform patients of available translated labels. Moreover, language barriers manifest at every step of diabetes care, from initial screening and medication adjustments to self-management education, device training, and following up with patients.

The pervasive effect of language barriers across these elements of care stresses the need for continued research and implementation of interpreter-supported interventions in diabetes management. While recent studies on interpreter-supported care are limited, their potential implications are profound. Addressing linguistic divides is not only about translation but about access to fair and comprehensive healthcare that accommodates all patients, regardless of language proficiency.
