title: United States patient preference and usability for the new disposable insulin device Solostar versus other disposable pens.
abstract: The uptake of insulin pen use has been slow in the United States, despite their advantages over the vial/ syringe. We present results of a United States subset of 150 patients with type 1/type 2 diabetes, who were enrolled in an open-label study, that assessed usability, pen features, and patient preferences for four prefilled insulin pens: SoloSTAR, FlexPen, Lilly disposable pen, and a prototype, Pen X. Overall, the SoloSTAR and FlexPen were more user-friendly; 95 and 88% of patients, respectively, completed the steps correctly (without safety/attach-needle step-deemed independent of device) versus the Lilly disposable pen (60%) and Pen X (61%; all p < 0.05). The SoloSTAR was rated highest most frequently for pen feature comparisons. Results suggest that the SoloSTAR and FlexPen could potentially facilitate insulin use in the United States.
