Abstract

Systems, methods, and computer readable storage media manage low blood glucose levels. The system receives blood glucose readings, where each reading includes a blood glucose value and a respective timestamp. The system compares each blood glucose reading to a predefined hypoglycemic event threshold, and identifies hypoglycemic events when a respective blood glucose reading is below the predefined hypoglycemic event threshold. For at least a subset of the identified hypoglycemic events, the system prompts a user for information associated with each hypoglycemic event. The information requested includes one or more of: symptoms associated with the respective hypoglycemic event; perceived causes of the respective hypoglycemic event; and treatment for the respective hypoglycemic event. In response to the prompting, the system obtains feedback about the identified hypoglycemic events and provides a report that includes at least a subset of the obtained feedback.

Core Innovation

The invention relates to a hypoglycemic event management system that receives a plurality of blood glucose readings for a person, where each reading includes a blood glucose value and a timestamp indicating when the reading was taken. The system compares each blood glucose reading to a predefined hypoglycemic event threshold and identifies a hypoglycemic event when a respective blood glucose reading is below the predefined threshold.

For at least a subset of the identified hypoglycemic events, the system prompts the person to provide information associated with each hypoglycemic event using a graphical user interface on a display device. The prompting includes displaying a plurality of hypoglycemic event icons, according to a stored sort order, corresponding to requested information including one or more of symptoms, perceived causes, and treatment for the respective hypoglycemic event. In response to the prompting, the system obtains feedback from the person using the graphical user interface.

The invention updates the stored sort order for the plurality of hypoglycemic event icons based on the obtained feedback and provides a report on the display device that includes at least a subset of the obtained feedback. Example report content includes a hypo awareness grid with (blood glucose level, symptom) pair counts, graphical presentation before and after hypoglycemic events, and hypoglycemic event pattern analysis such as correlation with time of day and day of week, including identifying patient unawareness, and providing recommended changes to activities.

Claims Coverage

The independent claims are directed to a method at a computer system, a corresponding computer system, and a non-transitory computer-readable storage medium. Across these independent claims, the core inventive feature set comprises receiving timestamped blood glucose readings, comparing to a predefined hypoglycemic event threshold, prompting via a GUI with hypoglycemic event icons in a stored sort order for symptoms, perceived causes, or treatment, obtaining feedback, updating the icon sort order based on feedback, and providing a report including at least a subset of the feedback.

Across the independent claims, the system centers on threshold-based identification of hypoglycemic events from timestamped blood glucose readings, GUI-based prompting with a stored sort order of hypoglycemic event icons for symptoms, perceived causes, or treatment, feedback collection, feedback-driven update of icon ordering, and report generation including at least a subset of the feedback. Dependent refinements specify how the icon sort order is updated, cross-device pattern identification, and particular report visualizations such as the hypo awareness grid and graphical before and after presentation, including possible recommended activity changes.
