so much data/information, so little time!
Diabetes Technology 03/2020 - Thomas Züger, UDEM Inselspital
YEAR 20002-3 min writing summary
11 min checking of blood glucose values(SMBG) 2
No continuous glucose monitoring (CGM)No wearables
Rare in between visits contact
YEAR 202016 min electronic medical record (EMR) per visit 1
20 min insulin pump data + 15 min pump settings (bolus calculator etc.) 2
30 – 40 % pat. with CGM (10 – 20 pages of CGM data) 3, 4
Integration of fitness data, meal data etc.Mail, phone-calls, data-sharing (cloud-solutions)

The burden of diabetes for patients with diabetes (PWD)
Diabetes Technology 03/2020 - Thomas Züger, UDEM Inselspital
Burden of time • 2005: Average 58 min a day on self-care 1
• 2018 2: • adult with T2DM 66 min a day• child with T1DM 78 min a day

Who takes care of the diabetes management?
Diabetes Technology 03/2020 - Thomas Züger, UDEM Inselspital
“It is clear that diabetes remains unique among chronic conditions in the extent to which therapy is controlled by the patient and factors that shape behaviour”
David G. Marrero; American Diabetes Association President
19
Self-adjustement of therapy between clinical visits
Diabetes Technology 03/2020 - Thomas Züger, UDEM Inselspital
• Survey in 47 patients with DM1 on insulin-pump (average 6 years Diabetes duration = experienced)
never sometimes frequent all the time Nimiri R, Phillip M, ATTD Madrid, 2020
20
Obstacles for technology utilization and self-adjustment
• Need to download data & contact HCP• 50-70% of patients never download data of various
devices between visits 1
• Lack of knowledge / ability / confidence• Patients report low confidence and competence to
undertake retrospective review of CGM data 2
• Lack of ability to interpret data (amount of data / information overload) 3
• Decision making fatigue & alarm fatigue 2

Acceptance of automated decision support by PWD
Diabetes Technology 03/2020 - Thomas Züger, UDEM Inselspital
Willing to try
Would you be willing to use an algorithm that adjusts your insulin pump settings
after downloading your devices at home?71.7%
Would you be willing to use an algorithm that suggests insulin dosing on real-
time?68.1%
Would you be willing to get text messages each time you need insulin adjustment? 50%
Would you trust dosing recommendations given by automatic algorithm? 82.6%
Do you think that automated algorithm for insulin dosing will release some of the
burden of managing diabetes?76%

Decision support – how it may look like for PWD
Diabetes Technology 03/2020 - Thomas Züger, UDEM Inselspital
The last 3 times after exercise you had night-time hypoglycemia!
Ok – what do you recommend Reduce your
basal insulin by 20% for 8h and eat 10g of Carbs after exercise

Consensus on Digital/Virtual Diabetes Clinic, ATTD Madrid 2020
26
Adapted from Phillip M, ATTD 2020, Madrid
Consensus on Digital/Virtual diabetes clinicMadrid February 18th 2020 – Highlights
• Digital – Virtual diabetes clinic should be developed for all patients with diabetes (PWD)
• Digital clinic aim to empower PWD to self treat their diabetes
• Data ownership should be regulated worldwide – it’s for the patients to decide whom to share it with
• Digital clinic may replace some of the F2F appointments and increase interactions between visits
• Easy, passive transmission of data from all different devices to integrate, interpret and create a meaningful advice for both HCPs and PWD
