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.


Duration: 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 ↓ and IG2↓
  • HBA1c ≤ 7.5%: IG1 → and IG2↓
  • QOL: IG1→ and 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:



  • Blood glucose
  • Blood pressure
  • Test strips (glucose)


Staff resources

  • Staff for monitoring and phonecalls/sms



Health care utilization: NA
