Study Reveals Racial Disparities in Diabetes Care Outcomes

A recent study has revealed significant disparities in diabetes care outcomes across racial and ethnic groups within the Enhanced Primary Care Diabetes (EPCD) model. Conducted at the Mayo Clinic Rochester, the research assessed the efficacy of this nurse-led care delivery model that aims to improve diabetes management in primary care settings. The findings indicate that while overall engagement with the program was high, not all racial groups benefited equally.

The study analyzed health records from 1,749 adults aged 18 to 75 who participated in the EPCD program between January 1 and December 31, 2020. Researchers followed the progress of these patients until August 1, 2022, evaluating how long it took to achieve five key diabetes care goals known as D5. These goals included maintaining a blood pressure reading below 140/90, taking statin medication for cholesterol management, achieving an HbA1c reading below 8%, living tobacco-free, and taking daily aspirin as appropriate.

Overall, 60.7% of the patients met the D5 during the study period. However, the analysis revealed stark differences among racial groups. Black patients with diabetes were significantly less likely to meet the D5 compared to their White counterparts, with a hazard ratio of 0.68 (95% confidence interval: 0.52-0.90; P = .007). In contrast, Asian and Hispanic patients did not display significant differences in outcomes when compared to White patients.

The study further highlighted disparities in care engagement. Asian patients had fewer interactions with nurses, averaging only 0.8 touch points per year, while Black patients had more frequent engagements, with a median of 2.2 touch points annually. Hispanic patients showed no significant variation in nurse contact.

Several factors contributed to the slower attainment of the D5 goals. Younger age, insulin use, fewer baseline D5 components met prior to entering the program, and a lower medication count at the start of the study were all associated with delayed progress.

These findings underscore the need for tailored approaches in chronic disease management programs, particularly those addressing diabetes. Despite increased engagement with care team nurses, Black patients faced significant barriers to achieving key health goals, suggesting that socioeconomic and cultural contexts must be considered in the design and implementation of healthcare programs.

The research was published in The Annals of Family Medicine, authored by J. R. Herges and colleagues, underlining the importance of addressing racial disparities in healthcare. The American Academy of Family Physicians has emphasized the necessity for ongoing efforts to ensure equitable health outcomes across diverse populations, highlighting the critical need for systemic change in diabetes care practices.
