OP041 - SOCIOECONOMIC DISPARITIES IN ACCESS TO CGM FOR ADULTS WITH DIABETES. RESULTS FROM THE GERMAN DPV REGISTRY (ID 131)
Abstract
Background and Aims
Data on socioeconomic disparities in access to CGM in adults is still rare in Europe. We therefore investigated differences in CGM usage between differently deprived areas in Germany.
Methods
In adults with type 1 diabetes (T1D) or type 2 diabetes (T2D) from the German prospective diabetes follow-up registry (DPV), we analyzed CGM use (any use or regular use: ≥ 90 days per year) in 2021 by quintile of area deprivation (German index of Multiple Deprivation [GIMD] 2015, from Q1, least deprived, to Q5, most deprived districts), using multiple adjusted regression models.
Results
In 2021, 58.0% of adults with T1D (n=9,368) and 12.3% of adults with T2D (n=27,949) used a CGM at any extent. A regular use was documented in 32.4% of adults with T1D and 4.8% of those with T2D. Socioeconomic disparities in access to CGM were greatest in adults with T2D using CGM regularly: 14.8% in Q1 districts (men: 15.5%; women: 13.8%) compared to ≤ 1.8% in Q2-Q5 districts (p for trend <0.001). The difference was greater in T2D individuals without insulin therapy (12.1% in Q1 vs.≤ 0.3% in Q2-Q5, p < 0.001), than in those with insulin therapy (21.4% in Q1 vs. ≤ 4.3% in Q2-Q5, p < 0.001). The largest proportion of adults with T2D using CGM regularly was in Hamburg (>10%).
Conclusions
For patients with T2D in Germany in 2021, CGM use is almost limited to adults living in the least deprived districts, especially in the absence of insulin therapy.
