CGM Message Prioritization for Diabetes Data Overload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The sheer amount of data generated by continuous glucose monitors (CGMs) can overwhelm patients and clinicians, necessitating a more manageable presentation method to effectively manage diabetes.
Innovation Solution
A computer-implemented method and system that prioritizes and manages messages transmitted from a CGM to a diabetes management device, using a message generation, prioritization, and transmittal module to ensure critical glucose level alerts are noticed promptly, while consolidating less urgent data for efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If continuous glucose monitoring data is transmitted continuously to the diabetes management device, then the completeness of glucose monitoring information is improved, but the patient becomes overwhelmed by the sheer amount of data
Solution Approach 1:
The patent extracts and transmits only specific critical information (glucose level alerts and status messages) from the continuous glucose monitoring data stream, rather than transmitting all raw data. This selective extraction maintains the essential safety information while eliminating data overload for the patient.
Solution Approach 2:
The system changes the parameter of data transmission from continuous raw data to processed alert-based information. By transforming the data representation format and selecting only parameters that indicate critical glucose levels or device status, the system reduces information overload while preserving clinically relevant data.
2Loss of information
If all glucose monitoring data is presented to the patient, then the completeness of information is improved, but the patient's ability to manage diabetes effectively deteriorates due to data overload
Solution Approach 1:
The system extracts only the most clinically significant data points - glucose level alerts and device status messages - from the continuous monitoring stream. This extraction process preserves essential safety information while removing redundant data that would impede effective diabetes management.
Solution Approach 2:
The diabetes management device acts as an intermediary between the continuous glucose monitor and the patient. It processes, filters, and prioritizes data before presentation, serving as a mediator that transforms raw data into actionable clinical information.
3Speed
If critical glucose alerts are prioritized in transmission, then the responsiveness to critical events is improved, but the transmission of other important data may be delayed
Solution Approach 1:
The system maintains continuous monitoring and processes data streams without interruption. By continuously evaluating incoming glucose data and maintaining ready-to-transmit alert mechanisms, the system ensures both rapid response to critical events and ongoing collection of all relevant data for later transmission.
Solution Approach 2:
The system implements feedback mechanisms where transmitted alerts and status messages provide information about system operation and glucose trends. This feedback loop allows the system to maintain responsiveness while continuously gathering and transmitting relevant information about device status and glucose patterns.

AI summary
A computer implemented method for transmitting messages generated by a continuous glucose monitor (CGM), the method comprising: generating a first message at the CGM at a first time, the first message being related to blood glucose measuring; generating a second message at the CGM at a second time, the second time being after the first time, the second message being related to blood glucose measuring; determining an elapsed time since a transmitter of the CGM has transmitted data; determining whether the elapsed time is greater than a threshold; determining whether the second message is to be transmitted before the first message, in response to the elapsed time being greater than the threshold; and transmitting data corresponding with the second message before transmitting data corresponding with the first message to a diabetes management device, in response to determining that the second message is to be transmitted before the first message.
