Tailored care by diabetes nurses is not enough to overcome disparities in the regulation of type 2 diabetes between Dutch natives and ethnic minority groups

Background: Differences in diabetes regulation between patients from different ethnic background have been described. This may be reduced by regular visits to a diabetes nurse (RVDN) with the same mother tongue. We explored whether equal access to diabetes-related care, including RVDN with the same mother tongue, may result in similar diabetes regulation among ethnic minorities and Dutch natives. Methods: Patients with type 2 diabetes and an annual comprehensive diabetes evaluation were included in this study. For the analysis, we emphasized on the data of patients with RVDN and used descriptive statistics and nonparametric tests for between group comparisons. Results: From a total of 983 patients, 581 patients had RVDN of whom 266 (46%) Dutch natives, 199 (34%) Turks/Moroccans, and 116 (20%) patients from other ethnicities. Within the group of patients with RVDN, Turks/Moroccans had higher median fasting plasma glucose levels as compared with Dutch natives and other ethnic minorities (8.4 vs 7.9 and 7.3 mmol/L, P < 0.001), and a higher HbA1c level was found for both the Turks/Moroccans and other ethnic minorities, as compared to Dutch natives (62 vs 55 mmol/mol, P < 0.001). In addition, only 22% of Turks/Moroccans and 26% of other minorities achieved the American Diabetes Association/European Association for the Study of Diabetes (ADA/EASD)-recommended HbA1c target ≤53 mmol/mol, compared to 39% in Dutch natives. Conclusions: In patients with RVDN with the same mother tongue, we still found disparities in HbA1c levels between Dutch natives, Turks/Moroccans and other ethnic minorities. Other factors beyond Dutch language skills are likely to interfere.
