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.
Detailed description
In children with type 1 diabetes glucose deterioration occurred every day and night leading into low satisfaction with treatment. Unstable glycemic profile resulting in high glycemic variability depends on the adjustment of insulin dosing to the current needs of the organism. The calculation of prandial insulin dosing is a complex process which involves such factors as preprandial blood glucose level, the amount of food taken, the glycemic index of carbohydrates, the insulin/carbohydrate exchange ratio, the active insulin level following the previous bolus. Currently, in patients treated with continuous subcutaneous insulin infusion (CSII) insulin pumps are equipped with bolus calculators which help to calculate prandial insulin dosing and thus contribute to improve post-prandial blood glucose levels. The aim of the study was to determine whether the patient's support expert VoiceDiab system have stabilised diurnal glucose profile in children with type 1 diabetes treated with insulin pumps.
Interventions
DEVICEVoiceDiab expert system
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.
