NCT02403427

Brief Summary

The purpose of this study to conduct the preliminary investigation on the efficacy and safety in terms of postprandial glucose value and the rates of hypoglycaemia when expert VoiceDiab system supports patient's decision on prandial insulin programming in insulin pump therapy.

Study Arms (2)

VoiceDiab expert system

EXPERIMENTAL

the VoiceDiab system using before every main meal; three times per day.

Device: VoiceDiab expert system

manual calculation

NO INTERVENTION

manula insulin calculation before every main meal; three times per day

Interventions

Decision support system VoiceDiab this is computer-based system constructed for mobile phone devices working on the server. Patients in experimental arm get the mobile phone application for 4 days. Glucose control will be done by two methods SMPG and CGM. Before every study's meal insulin dose with type of bolus will be indicate by VoiceDiab.

Also known as: patient's decision supporting system
VoiceDiab expert system
