    Abstract:
    INTRODUCTION: Real-world data comparing outcomes of type 2 diabetes mellitus (T2DM) patients initiating different insulin regimens can help with treatment decisions and patient management. Clinical and economic outcomes following initiation with insulin glargine disposable pen (GLA-P) or insulin detemir disposable pen (DET-P) in T2DM patients were compared over 1-year follow-up. METHODS: This retrospective cohort analysis was conducted on data in a US national managed care claims database (July 2006 to September 2010) from patients initiating insulin treatment with GLA-P or DET-P. Treatment persistence, adherence, glycated hemoglobin (A1C), hypoglycemic events, and healthcare costs during follow-up were compared. RESULTS: In all, 1682 patients were identified; 1016 (60.4%) started using GLA-P, 666 (39.6%) started using DET-P. After 1:1 propensity score matching, each cohort comprised 640 patients. Patients initiating GLA-P were significantly more likely to persist and adhere to treatment, and used a lower daily consumption dose. Over the last quarter of follow-up, fewer GLA-P users switched to DET-P compared with those switching from DET-P to GLA-P. GLA-P was associated with lower A1C levels and higher reduction of A1C levels from baseline, with no significant difference in the number of patients having hypoglycemic events. Patients in both cohorts had similar total and diabetes-related healthcare costs, but healthcare costs were lower in the GLA-P cohort for each 1% reduction in A1C from baseline. CONCLUSION: This real-world study demonstrates that patients initiating GLA-P were more likely to persist with and adhere to treatment, with better glycemic control and similar overall hypoglycemia rate at no increase in healthcare cost.
