Predicting analyte levels based on intermittent sensor data

A method for generating an analyte level profile for a user, the method comprising:

• acquiring first sensor data from an analyte sensor, wherein the first sensor data reflects analyte levels of a user who is wearing the analyte sensor, and wherein the first sensor data is collected over a first time period;
• using the first sensor data to generate a profile for the user, wherein the profile tracks the analyte levels of the user throughout the first time period;
• during a second time period that is subsequent to the first time period, determining that sensor data is no longer being acquired from the analyte sensor, resulting in the first sensor data being discontinuous analyte data;
• using the discontinuous analyte data to generate predicted analyte level data for the user;
• updating the profile by including the predicted analyte level data;
• determining that the predicted analyte level data is stale, wherein determining that the predicted analyte level data is stale comprises designating the predicted analyte level data as unreliable for continued use without acquisition of new sensor data, and wherein determining that the predicted analyte level data is stale comprises:
• (i) determining that a time elapsed since acquisition of most recent sensor data from the analyte sensor exceeds a predetermined staleness threshold;
• or
• (ii) determining that a confidence level or accuracy metric associated with the predicted analyte level data has fallen below a threshold value due to an absence of updated sensor data;
• in response to determining that the predicted analyte level data is stale, generating a prompt to the user to facilitate acquisition of new analyte sensor data, wherein the prompt instructs the user to use a new analyte sensor to acquire the new analyte sensor data or to facilitate acquiring the new analyte sensor data from the first analyte sensor;
• and
• acquiring the new analyte sensor data from either the first analyte sensor or the new analyte sensor, wherein the second sensor data is acquired after the prompt is provided to the user.

A method for generating a health model for a user the method comprising:

• acquiring first sensor data from an analyte sensor, wherein the first sensor data reflects a physiological response of a user who is wearing the analyte sensor, and wherein the first sensor data is collected over a first time period;
• using the first sensor data to generate the health model for the user, wherein the health model tracks the physiological response of the user throughout the first time period;
• during a second time period that is subsequent to the first time period, determining that updated sensor data is no longer being acquired from the analyte sensor, resulting in the first sensor data being periodic sensor data;
• using the periodic sensor data to generate predicted physiological response data for the user during the second time period;
• updating the model by including the predicted physiological response data;
• determining that the predicted analyte level data is stale, wherein determining that the predicted analyte level data is stale comprises designating the predicted analyte level data as unreliable for continued use without acquisition of new sensor data, and wherein determining that the predicted analyte level data is stale comprises:
• (i) determining that a time elapsed since acquisition of most recent sensor data from the analyte sensor exceeds a predetermined staleness threshold;
• or
• (ii) determining that a confidence level or accuracy metric associated with the predicted analyte level data has fallen below a threshold value due to an absence of updated sensor data;
• in response to determining that the predicted analyte level data is stale, generating a prompt to the user to facilitate acquisition of new analyte sensor data, wherein the prompt instructs the user to use a new analyte sensor to acquire the new analyte sensor data or to facilitate acquiring the new analyte sensor data from the first analyte sensor;

• acquiring the new analyte sensor data from either the first analyte sensor or the new analyte sensor, wherein the second sensor data is acquired after the prompt is provided to the user.
