An overview of the feasibility components to be assessed

Feasibility componentData source (indicator of feasibility)
Practicality of technology/intervention

  • Qualitative interviews

  • Fitabase (sync compliance, missing data and response to haptic prompt)

  • LibreLinkUp (scan compliance)

  • Diasend (missing data, identification of glucose sensor sensor-related issues)

  • Project records (identification of need to dispatch additional glucose sensors, number of individuals screened, rate of eligibility, study uptake and retention)

  • Ethica data (data sources, enrolment into full* or restricted† coverage)

Acceptability of technology/intervention

  • Qualitative interviews

  • Fitabase (activity tracker wear time)

  • Diasend (glucose sensor wear time, digital footprint of time taken to move onto the next glucose sensor that is, sensor delay?)

  • Project records (changes to goal settings, manual withdrawals, attendance at appointments, retention to follow-up)

  • Ethica data (digital footprint of application usage, Bluetooth and Wi-Fi status, battery status, electronic withdrawal)

  • *Full coverage: application usage, screen state, Bluetooth, Wi-Fi, GPS, pedometer, accelerometer, gravity, gyroscope, linear acceleration, magnetic field, orientation, battery and survey responses.

  • †Restricted coverage: application usage, screen state and survey responses.

  • GPS, global positioning system
