Utilization and impact of SLGT2 inhibitors among diabetes patients in a nationally representative survey: Findings from NHANES 2013-2020.

Background and Aims: The purpose of this study is to examine patterns of utilization for antidiabetic medications among a nationally representative sample of the US population following the introduction of SGLT2 inhibitors in 2013.
Methods: The study utilized National Health and Nutrition Examination Survey (NHANES) data from 2013 to 2020 to identify adult patients with diabetes using antidiabetic medication. The proportion of patients with diabetes using different antidiabetic medications, including SGLT2 inhibitors, was plotted over time. To assess the statistical significance of the utilization trend of SGLT2 inhibitors and other oral antidiabetics, logistic regression models were employed.
Results: A weighted total of 26,421,357 individuals included in our study were diagnosed with diabetes. Among these, 18,751,659 diabetes patients were identified as medication users, with 1,058,686 (5.7 %) of them taking SGLT2 inhibitors. Over the 7-year study period, the percentage of patients taking SGLT2 inhibitors increased 21-fold, from 0.4 % in 2013-2014 to 9.4 % in 2017-2020. Despite this substantial increase, the utilization of other second-line antidiabetic agents, such as sulfonylureas, DPP-4 inhibitors, GLP-1 receptor agonists, and TZDs, remained relatively stable during the same period.
Conclusions: SGLT2 inhibitor utilization has significantly increased among US diabetes patients; however, their rise has not substantially impacted the use of other second-line antidiabetic agents. Further research is needed to understand the social determinants and potential barriers affecting the broader adoption of these beneficial medications.
