Glucose Monitoring: why?
• Evaluate the efficacy of current therapy
• Make insulin and medication dose adjustments
• Monitor treatment safety
• Enable patients to better understand the impact of diet,
exercise, illness, stress, and medications on glucose
levels
• Enable patients to recognize and treat hypoglycemic
and hyperglycemic episodes
• Select the most appropriate drug therapy
modified from Bailey T.S., et al. AACE/ACE GM Consensus Statement 2016
Quale tra le seguenti ritenete la modalità più
efficace/appropriata per l’implementazione della
telemedicina in Diabetologia?
1. Real-time video conferencing
2. Comunicazione tramite websites
3. Comunicazione tramite e-mail
4. SMS e messaggi via smartphone
Key Telemedicine Components in Diabetes
1. Accurate data collection in digital
format
2. Electronic medical record
3. Protocols for distant data analysis
→ response to data, patients’
education, intervention
4. Variety of communication tools to
permit effective dialogue between
patients and HCPs (Internet,
telephone/cellphone, Bluetooth,
modem, cable)
5. System for automatically flagging
and providing feedback for outlier
data
6. Data sharing
Modified from Klonoff D, J Diabetes Sci Technol, 2009
▪ Patient-collected physiological data
(SMBG, CGM, BP)
▪ Lab data (HbA1c, lipid levels)
▪ Behavioral information (dietary
intake, exercise)
▪ Medication dosages, allergies, and
other history
▪ Subjective symptoms of
hypoglycemia or other complaints
▪ Pertinent event data (emergency
room visits, hospitalizations,
ophthalmology visits, etc.)
▪ Images of retinal photos, wounds, or
other structures
Tools Information
Quale entità di riduzione di HbA1c può essere ottenuta
con l’uso della telemedicina nel diabete?
1. Non apprezzabile
2. 0,5%
3. 1%
4. 1,5%
5. Si è osservata solo una riduzione dei casi di marcato
scompenso glicemico
Risposta esatta: 2
Web-based Care Management in Patients with
Poorly Controlled DM (HbA1c ≥9.0%)
▪ Notebook computer, glucose meter, and blood pressure monitor
▪ Notebook computer programmed to connect to a diabetes education and management website
▪ Messaging system via the website (care manager responded to queries within 1 working day)
▪ Web-enabled diabetes educational modules
▪ Recall of participants who did not login to the website during a 2 week period

L’uso della telemedicina nel diabete ha mostrato:
1. Un miglioramento del controllo glico-metabolico
2. Un miglioramento della qualità di vita
3. Una riduzione degli episodi di ipoglicemia
4. Un potenziale impatto su parametri lipidici e pressori
5. Tutte le precedenti

Impact of the "Diabetes Interactive Diary" Telemedicine on
Metabolic Control, Risk of Hypoglycemia, and QoL in T1DRossi MC et al., Diabetes Technol Ther. 2013 Aug;15:670-9
▪ Diabetes Interactive Diary (DID): carbohydrate/bolus calculator
promoting the patient-physician communication via SMS
▪ 127 T1D patients not previously educated on carbohydrate counting
assigned to DID or standard of care
▪ No between-group difference in HbA1c levels
▪ Lower risk of grade 2 hypoglycemia with DID
▪ DID improved the "perceived frequency of hyperglycemic
episodes" scale of the DTSQ and the "social relations" and the
"fear of hypoglycemia" dimensions of the DSQLS
Web-based Intervention and Physical Outcomes
Associated with Diabetes among Adults > 60 yrsBond GE, et al., Diabetes Technol Ther. 2007;9:52–9
▪ RCT, 62 subjects (87% with T2D), 6-month follow-up
▪ Nurse-based
▪ Computer experience or computer literacy not required for eligibility
▪ Several behavioral strategies (coaching, motivational, and social
support)
▪ Mean HbA1c level decreased in the intervention group from
7.0% to 6.4% and in the control group from 7.1% to 7.0% (P =
0.01)
▪ Significant reductions in SBP, DBP, total cholesterol and weight
in the intervention group
“this study disproves the myth that seniors will not be attracted to the
Internet as a way of communication”
Interactive Telemedicine (TM): Effects on
Professional Practice and Health Care OutcomesFlodgren G et al., Cochrane Database Syst Rev 2015
• 93 eligible trials (N = 22,047 participants)
• 21 in patients with diabetes
• Education and advice for self-management, specialist consultations for
diagnosis and treatment decisions
• Telephone, e-mail, SMS
• Lower HbA1c with TM: -0.31% (95% CI -0.37 to -0.24; P < 0.00001)
at a median of nine months follow-up
• Some evidence for a decrease in LDL (4 studies, N = 1692; -12.45,
95% CI -14.23 to -10.68; P < 0.00001) and blood pressure (4
studies, N = 1770: SBP:-4.33, 95% CI -5.30 to -3.35, P < 0.00001;
DBP: -2.75 95% CI -3.28 to -2.22, P < 0.00001) with TM

Frecce di tendenza
• Le tendenze sono indicate dalle frecce
• La tendenza si genera in base all’andamento che la glicemia
ha avuto negli ultimi 15-20 minuti e cioè se è stata stabile, se
sta aumentando o se sta diminuendo
• Essa predice ciò che accadrà nei successivi 30 min se non ci
sono nuove variazioni
• Ciascun sistema ha un sua definizione di tendenza.
Quali decisioni prendere in basealle frecce di tendenza?

“Each patient may become a big-data producer. The data we generate at home or in the wild will vastly exceed what we accumulate in clinical care”.“We’re trying to create these big collages of different data modalities — from the genomic to the environmental to the clinical — and link them back to the patient.”
