Sensor-augmented pump therapy in type 1 diabetes

Abstract

Recent developments in technology have ushered in a new era of managing type 1 diabetes. Continuous glucose monitoring is rapidly becoming an accepted adjunct to traditional self-monitoring of plasma glucose, and the marriage of continuous glucose sensors to continuous subcutaneous insulin infusion is the first step towards the development of a true artificial pancreas. The purpose of this review is to familiarize the reader with the new glucose sensors and discuss the literature evaluating their accuracy and effectiveness. Current models of continuous glucose sensors are still less accurate than traditional methods of blood glucose monitoring but provide information regarding trends that cannot be obtained with blood testing. Short-term studies of continuous glucose sensors have demonstrated reduction in glycosylated hemoglobin levels and time spent in hypo- and hyperglycemic ranges. Patient acceptance and satisfaction with sensors has been shown to depend on the quality of the data, comfort of wear, and ease of use. Sensor-augmented pump therapy represents a landmark improvement in diabetes treatment and will likely become the standard of care. Future work should focus on improvements in sensor accuracy and development of user-friendly algorithms to assist patients with self-management.
