Assessing Insulin Delivery Device Satisfaction in Patients with Type 1 and Type 2 Diabetes.

Over the past several decades, insulin treatment has changed drastically, not only with the development of further insulin analogs but also with the introduction of novel insulin delivery devices such as pumps and pens. In addition, adjunct devices such as continuous glucose monitors and sensor-augmented pumps have become increasingly used in clinical care, increasing the volume of information available to patients and providers. However, with the development of new devices it has become clear that along with the many benefits of these advances, the use of these devices can also present a burden to people with diabetes. For example, some patients report being overwhelmed by too much data when using continuous glucose monitors. Furthermore, there are concerns regarding the accuracy of some of these new devices, particularly for glucose monitoring. As a result, some patients may choose not to use available devices, despite the recognized benefits. Therefore, it is critical to understand how the various insulin delivery devices available currently and in the future affect patients in terms of their diabetes management and perceived burdens and to understand which patient characteristics may predict a lack of satisfaction with these devices. This critical gap in our knowledge is addressed in an article in this issue of the journal through the development of a questionnaire that allows for a better understanding of the impact of insulin delivery devices on quality of life and diabetes management among both type 1 diabetes and insulin-dependent type 2 diabetes patients. The novelty, as well as limitations, of this new instrument for the assessment of insulin delivery device satisfaction are discussed.
