N2 - Aims: To assess the level of adherence to glucagon-like peptide-1 receptor agonist (GLP-1RA) treatment using real-world data and to investigate the sociodemographic and clinical factors associated with discontinuation of GLP-1RAs. Methods: First-time users of GLP-1RAs with type 2 diabetes mellitus (T2DM), aged ≥18 years, in the period 2007 to 2020, were identified using Danish registries, allowing all participants a minimum of 18 months’ follow-up. Adherence to GLP-1RA therapy (medication possession ratio >0.80) and discontinuation of GLP-1RA therapy was estimated at 6- and 12-month follow-ups. Multivariable cause-specific Cox regression was used to identify sociodemographic and clinical factors associated with risk of discontinuation. Results: In total, 44 343 first-time users of GLP-1RAs with T2DM were identified (mean age 58.6 years, 42.7% female, median duration of T2DM 6.8 years, median glycated haemoglobin level 65 mmol/mol). The absolute risk of discontinuing GLP-1RA treatment within 6 months was 14.2% (95% confidence interval [CI] 13.9–14.6) and 21.2% (95% CI 20.8–21.5) within 12 months. At 6 months, 50.4% were adherent to GLP-1RA therapy and at 12 months, 48.6% remained adherent. In the multivariable model, younger (<40 years) and older age (>75 years), higher Charlson Comorbidity Index score, lower household income, high school and longer university degree as educational attainment level, and longer diabetes duration were associated with a higher risk of discontinuing GLP-1RA treatment. Conclusion: Approximately one in five patients discontinued GLP-1RA therapy within the first 12 months and only half were adherent. Overall, lower socioeconomic status and higher comorbidity burden were associated with higher risk of discontinuing GLP-1RA treatment.
