Abstract: Systems and methods for processing sensor data and end of life detection are provided. In some embodiments, a method for determining the end of life of a continuous analyte sensor includes evaluating a plurality of risk factors using an end of life function to determine an end of life status of the sensor and providing an output related to the end of life status of the sensor. The plurality of risk factors may be selected from the list including the number of days the sensor has been in use, whether there has been a decrease in signal sensitivity, whether there is a predetermined noise pattern, whether there is a predetermined oxygen concentration pattern, and error between reference BG values and EGV sensor values.

Abstract: Certain aspects of the present disclosure relate to methods and systems for technical support of continuous analyte monitoring and sensor systems. In certain aspects, a method includes sensing, by an analyte sensor, analyte levels of a patient to generate one or more sensed signals. The method further includes generating, by a transmitter, a plurality of event indications based on the one or more sensed signals. The method further includes transmitting, by the transmitter, the plurality of event indications to a processor. The method also includes receiving the plurality of event indications indicating one or more errors associated with the analyte sensor. The method further includes determining one or more root causes associated with the plurality of event indications based on a pattern associated with the plurality of event indications. The method also includes taking one or more actions to resolve the one or more root causes.

Abstract: Systems and methods for processing sensor analyte data are disclosed, including initiating calibration, updating calibration, evaluating clinical acceptability of reference and sensor analyte data, and evaluating the quality of sensor calibration. The sensor can be calibrated using a calibration set of one or more matched sensor and reference analyte data pairs. Reference data resulting from benchtop testing an analyte sensor prior to its insertion can be used to provide initial calibration of the sensor data. Reference data from a short term continuous analyte sensor implanted in a user can be used to initially calibrate or update sensor data from a long term continuous analyte sensor.
