The diabetes epidemic in the United States (US) presents a critical challenge due to a shortage of endocrinologists, leaving primary care providers (PCPs) to manage most cases. Diabetes Care and Education Specialists (DCES), primarily Registered Nurses (RNs) and Registered Dietitian Nutritionists (RDNs), offer crucial support. RDNs deliver Diabetes Self-management Education and Support (DSMES) and Medical Nutrition Therapy (MNT), while also assisting with insulin pump education, continuous glucose monitoring (CGM) training, and medication titration. Integrating DCES into primary care clinics proves successful in enhancing patient care. Additionally, in rural US/Mexico border communities, culturally competent MNT and DSMES, often facilitated by Promotoras, are crucial. The systematic review by Benson et al. suggests expanding RDNs' scope to include initiating and titrating medications, highlighting their potential to improve diabetes care outcomes. This issue aims to broaden your understanding of the vital role played by RDNs and DCES in enhancing diabetes management within the primary care setting.
