Patients' Preferences for Connected Insulin Pens: A Discrete Choice Experiment Among Patients with Type 1 and Type 2 Diabetes.

ABSTRACT:

Background

This study quantified how people with diabetes value the unique features of connected insulin pens and related mobile apps, and the underlying reasons for preferring connected versus non-connected insulin pens.

Methods

A discrete choice experiment (DCE) was conducted in the USA and UK to elicit preferences of adults (≥ 18 years) with type 1 or 2 diabetes for attributes of insulin pens. Attributes included device type, dosing support, glucose monitoring, additional app features, and data sharing. Relative attribute importance (RAI) scores were calculated to capture the relative importance of an attribute. Predicted choice probabilities were obtained to compare different profiles for connected and non-connected insulin pens.

Results

The DCE was completed by 540 participants (58.9% male; 90.7% Caucasian; mean age, 58.3 years; 69.4% type 2 diabetes). Participants most valued the possibility of using a connected insulin pen with dosing support and automated dose logging (RAI = 39.9%), followed by automatic transfer of glucose levels (RAI = 29.0%), additional features of tracking diet and physical activity (RAI = 14.6%), data sharing (RAI = 13.6%), and device type (RAI = 2.9%). All profiles of connected insulin pens were preferred over a non-connected pen (p < 0.001), and pen profiles with advanced features were preferred over those without (p < 0.001). Preferences differed by age but not diabetes type, country of residence, or insulin regimen.

Conclusion

People with diabetes in the USA and UK prefer connected over non-connected insulin pens due largely to the availability of automated logging of dose and glucose levels.
