Abstract

Objective: Insulin is one of the most efficacious treatments for hyperglycemia; however, adherence to insulin therapy is poor, impacting its efficacy. Thus, the objectives of this study were to determine if persistent use of a new insulin delivery option, V-Go, improved clinical outcomes and secondly compare clinical and economic outcomes between persistent use of V-Go and conventional insulin delivery (CID).

Methods: A retrospective review of an outpatient clinic's records was performed. Patients initiating V-Go with documented persistent use of V-Go or resumed persistent use of CID after short-term V-Go use were included (≥5 months of persistency). Baseline data and a total of two post-V-Go or CID initiation visits were examined for clinical and economic outcomes. Cost-effectiveness of each therapy was calculated by dividing the mean cost difference (baseline to office visit 2) by the mean change in A1c (baseline to office visit 2).

Results: V-Go persistent patients had a significant decrease in A1c (−1.42; p < 0.001). Between baseline and office visit two, they required less insulin units/day and units/kg and had significantly lower A1c, insulin units/day, insulin units/kg, and 30-day insulin costs than CID patients. V-Go persistent patients had a lower incremental cost by $695.61 per 1% change in A1c compared to CID persistent patients.

Conclusions: Utilization of a new insulin delivery option resulted in improved clinical outcomes compared to CID and was more cost-effective. Clinicians and health plans should consider the use of new insulin delivery options for the management of patients with diabetes on insulin therapy to promote persistence.
