Focus Group Report 06/06/218

Attendees

  • Patients – Megan Blisset, Philippa Cooper
  • Investigators – Chukwuma Uduku, Robert Spence, Kehzi Li, John Daniels, Narvada Jungee, Rebecca Elkington, Ryan Armiger, Dan Wells, Camille Demasson
  • Minutes and report compiled by - Chukwuma Uduku

Home Screen

  • General layout of domains and bifocal display well received Agreed Prroposals
  • Allow the user to swipe through different (customisable) information in the status indicators. Content suggestions below:
    • Meals domain - Last meal (total CHO and bolus insulin delivered), Insulin on-board, Active Carbs
    • Exercise domain - Heart rate

Bi-Focal Display Agreed Proposals

  • Current Blood glucose to be large and central with trend arrow
  • Label at the tsop should include day of the week
  • Ability to click on current date and from their select any historical date to jump to
  • Limit number of previous days represented on the bi-focal sidebands to three
  • Increase size to maximise usage of screen real estate
  • Timestamped food to be placed on the graph at different heights relative to CHO content (High CHO meal plotted above low CHO)
  • Consider loss of predicted future glucose trajectory & historical glucose data when approaching the end & entering a new day respectively
  • Consider use of a new, empty bifocal display when entering a new day
  • Ability to enter insulin doses is essential. A few ideas:
    • Eter correction in food and add to food logs. This is a problem for doses not taken with meals.
    • Insulin section, displaying on board etc. Ideas in debrief
  • Incorporation of temporary basal rate on the graph (possibly with Y-axis values on the right)
  • Use of pastel colours for graph background. Considering darker shades out of range with a smooth gradient to a light shade in target range
  • Add insulin bolus to the bi-focal display, similar to with food and exercise activities

Meals/Food Domain Agreed proposals

  • To overcome time discrepancies around pre-bolus insulin, all meals require user to enter planned time of ingestion
  • Preference to manually enter figures for macronutrients above using a picker
  • Adding photos to favourite meals well received
  • Consider use of scanning barcodes to pull macronutrient content. (Potential drawbacks include: - portion size, units, cooking methods)
  • Show previous delta blood glucose rise and bolus insulin required when choosing a previously selected meal
  • Incorporate alcohol (units)
  • Be able to access detailed information about a recommended insulin dose (e.g. Amount in correction and amount for meal) Ideas in debrief
  • Quantitative CHO log & qualitative protein and fat (low, mid, high)
  • Incorporate a library with macronutrient content common meals

Exercise Agreed Proposals

  • Be able to specify if exercise is aerobic, anaerobic or mixed
  • Consider the app logging periods of increased activity for future review (not an alert)

Health Agreed Proposals

  • Offer user additional & customisable tags for retrospective review (e.g. menstrual cycle, travel)
  • Popup calendar to retrospectively identify filtered parameters well received

Advice

  • Use this domain for identified trends, warnings, possible basal insulin adjustments (e.g. temperature and blood glucose trend, weekend hyperglycaemia, overnight hypo’s etc..)
  • Interaction with advice will brush evidence on bifocal display
  • Ability to dismiss suggestions, can get annoying if repeated
  • Education is unnecessary, would have education before given the app and don’t want to encourage belief that it is an alternative.
  • Swipe across to see general statistics (e.g. total CHO, total exercise, total insulin delivered, glucose mean & range etc…)

Miscellaneous

  • Alarms: Options for do not disturb unless an emergency
  • Adjusting info level is important: Personalise from experienced to basic or children
  • Prioritise functionality
  • Personalisation important
