Abstract

An improved basal insulin management system and an improved user interface for use therewith are provided. User interfaces are provided that dynamically display basal rate information and corresponding time segment information for a basal insulin program in a graphical format. The graphical presentation of the basal insulin program as it is being built by a user and the graphical presentation of a completed basal insulin program provides insulin management information to the user in a more intuitive and useful format. User interfaces further enable a user to make temporary adjustments to a predefined basal insulin program with the adjustments presented graphically to improve the user'"'"'s understanding of the changes. As a result of being provided with the user interfaces described herein, users are less likely to make mistakes and are more likely to adjust basal rates more frequently, thereby contributing to better blood glucose control and improved health outcomes.
