The Diabeo software enabling individualized insulin dose adjustments combined with telemedicine support improves HbA1c in poorly controlled type 1 diabetic patients: a 6-month, randomized, open-label, parallel-group, multicenter trial (TeleDiab 1 Study).

Setting: France, 17 hospital sites

Study design:


Follow up: 6 months

Patient group:

Sample size:

Total: 180 (173)

IG1: 60 (56)

IG2: 59 (57)

CG: 61 (60)

Inclusion criteria:

– Diabetes type 1

– HbA1c ≥ 8.0%

Type of technology:

App “electronic logbook” (Diabeo)

– Monitoring

– Feedback on data (algorithms)

– Data transmission to medical staff

– teleconsultation



IG1: Electronic logbook but no teleconsultation. Face to face follow up at 3 and 6 months.

IG2: Electronic logbook and teleconsultations (phone call) every 2 week. Teleconsultations were focused on insulin dose adjustments and motivational support.


6 months

Add on: –

Control group:

no electronic logbook/app, follow up visits at hospital after 3 and 6 months.

Clinical effect/ Patient safety:

Clinical effect:

– HbA1c:

IG1 ↓ IG2↓

– HBA1c ≤ 7.5%

IG1 → IG2↓


IG1→ IG2→

Patient safety:

No difference in the frequency of symptomatic, nonsevere hypoglycemia episodes.

Patient experiences/ Staff experiences:

Patient experiences: 73% (IG2) stated that they wanted to continue with the app. 

Time spend on travelling to hospital, administrative procedures,

and waiting time:

IG1:288 min

IG2: –

CG: 274 min 

Staff experiences:

– Doctors average time spend on consultations:

IG1=70 min

IG2=72 min (tele)

CG=70 min

– Mean number of teleconsultations: 8.7

– Mean duration for one teleconsultation: 7.4 min.

Costs and organization:


Home monitoring equipment

– Blood glucose

– Blood pressure

– test strips (glucose)


Staff resources

– staff for monitoring and phonecalls/sms
