Summary

The purpose of this pilot study is to test the safety and feasibility of using two or three research modules in conjunction with an automated insulin delivery device (AID).

Description

This concept is implemented in the Adaptive Biobehavioral Control (ABC) system - ABC will use human-machine co-adaptation of AID, recognizing both the necessity for the control algorithm to adapt to changes in human physiology, and the necessity for the person to adapt to AID action. ABC will be implemented on the Web Information Tool (WIT) platform/system and includes the following modules to be used alongside the automated insulin delivery device facilitating behavioral adaptation:

  • Behavioral Adaptation Module (BAM) - a behavioral intervention deployed in a mobile app to assist a person's adaptation to automated insulin delivery by information and risk assessment primarily regarding glycemic risks, and
  • Auto Titration Module (ATM) - a web-based tool with an automated procedure to track risk status and changes in the participant's metabolic profile. This module will present updated insulin control parameters to the user once a week using a web-based format accessible to the participant.
  • Web-based Simulation Tool (WST) --a web-based education tool for participants to interact with their data to visualize and replay various scenarios to understand the impact of insulin parameter changes.

Design: Two-week baseline use of personal AID system followed by randomization 1:1 into two groups.

  • Group 1 will use their personal AID system and add an auto titration module (ATM) and web simulation tool (WST) in which insulin parameters may be adjusted on a weekly basis.
  • Group 2 will use their personal AID system and add the ATM / WST on a weekly basis as well as a behavioral adaptation module (BAM). The BAM will consist of information modules in which information only is given to participants (e.g. hypoglycemic risks).
