Automated artificial pancreas insulin onboarding and total daily insulin delivery adaptivity based on insulin history

A device, comprising:

• a processor operable to execute programming code including an artificial pancreas application;
• and
• a transceiver communicatively coupled to the processor and operable to receive and transmit signals containing information and exchange signals with a wearable drug delivery device,
• wherein the processor is operable to control delivery of insulin, and to:
• retrieve a portion of an insulin delivery history related to a user;
• determine whether the portion of the insulin delivery history meets insulin history sufficiency requirements;
• in response to a determination that the insulin delivery history meets the insulin history sufficiency requirements, set an initial total daily insulin value;
• transmit the initial total daily insulin value for receipt by the wearable drug delivery device;
• receive an indication that the wearable drug delivery device is being replaced with a replacement wearable drug delivery device;
• obtain updated insulin delivery history data collected during operation of the wearable drug delivery device;
• and
• based on the obtained updated insulin delivery history data, set a new total daily insulin value to be delivered based on a sum of parameters, wherein the parameters correspond to the initial total daily insulin value set for the wearable drug delivery device, and an amount of insulin delivered during a lifecycle of the wearable drug delivery device being replaced.
