研究概览
简要总结
The primary purpose of this study is to see whether a tool that predict blood glucose and suggest therapy advices can help type 1 diabetic patients.
详细描述
During this study, we would like to assess the efficacy in keeping blood glucose in a safe range (70-180 mg/dL) of the second generation of a Glucose Predictive and Therapy Advisory system in diabetic patients treated by basal-bolus insulin regimens using pumps or multiple daily injections. We want to compare the time spent in safe range while using the predictor and advisor outputs and when the patient is not using them. This is a randomized controlled crossover trial. Patient will come for two admissions of 3 days, one with the DIAdvisor system fully activated, and one with the prediction and advice features disabled.

结局指标
主要结局
Percentage of total time spent by patients in safe range (70-180mg/dL)
时间窗: during 3 days with DIAdvisor 2
The primary endpoint is the percentage of total time spent by patients in safe range (70-180mg/dL). A clinically significant benefit will be reached if an increase of at least 10% of total time in range is obtained while using DIAdvisor-2.
次要结局
- Percentage of total time spent in hypoglycemia (< 70 mg/dL)(during 3 days with DIAdvisor 2)
- Mean of YSI blood glucose during total period, night time and meal periods(during the two 3 days-hospitalizations)
- Percentage of total of time spent in hyperglycemia (>180 mg/dL)(during 3 days with DIAdvisor 2)
- Percentage paired glucose values(during 3 days with DIAdvisor 2)
- Coherence between system advices and physician recommendations > 0.80(during 3 days with DIAdvisor 2)
- Score of patient survey regarding the acceptability of DIAdvisor-2 system(during 3 days with DIAdvisor 2)
