Primary Outcome Measures
NameTimeMethod
Treatment Satisfaction: Accu-Chek® Micropump System vs. MDI, Measured by the Difference in the Diabetes Technology Questionnaire (DTQ) Total Change Score26 weeks

The two comparisons will be performed using a hierarchical procedure. First, the comparison between the Accu-Chek® Solo system vs. MDI will be performed and only if the corresponding Null hypothesis of no difference between both systems can be rejected, then the second comparison between Accu-Chek® Solo system and versus mylife™ OmniPod® will also be performed. The DTQ questionnaire consists of 30 questions with the individual Change Scores ranging from 1 to 5, where 1 represents 'Much worse' and 5 represents 'Much better'. The Total Change Score Range on this questionnaire is from 30 to 150 with higher scores representing lower impairment and improved outcomes.

Secondary Outcome Measures
NameTimeMethod
Average Time Spent on Infusion AssemblyBaseline up to Week 39
Device Satisfaction and Treatment PreferenceBaseline up to Week 39

Device Satisfaction and Treatment Preference was the main focus of part 2 questions of the DTQ. This part of the DTQ questionnaire consisted of individual sections with 9 questions each for the Blood Glucose Meter and Insulin Pump. Individual scores ranged from 1 (terrible) to 5 (excellent). Thus, the resulting sum score ranged from 9 to 45 for each type of device.

Therapy Success Confirmed by Glycated Hemoglobin (Hb1Ac) LevelsBaseline up to Week 39

Change in Glycated Haemoglobin (HbA1c) Levels from Baseline to Week 39

Therapy Success Indicated by Change in Body Mass Index (BMI)Baseline up to Week 39

This outcome measure represents one reported value calculated by combining weight and height to report BMI in kg/m\^2. Change in BMI from Baseline to Week 39.

Diabetes-Related Emotional Distress Assessed by Problem Areas in Diabetes Scale (PAID)-5Week 26 up to Week 39

The PAID-5 questionnaire consisted of 5 questions with answers ranging from 0 (not a problem) to 4 (serious problem). The total score was calculated as the sum of the individual questions, resulting in a number between 0 and 20 where lower scores represented lower distress.

Average Number of Self Monitoring of Blood Glucose (SMBGs) per day from Baseline up to Week 39

Number of ConsultationsBaseline up to Week 39

Consultations between scheduled visits, emergency and call center calls, hospitalizations and absenteeism from work/school.

Number of Pods/Infusion Assemblies Falling Off PrematurelyBaseline up to Week 39
Number of Participants With Skin Reactions (Including Type and Intensity)Baseline up to Week 39

Number of Participants who experienced Skin Reactions at the Insulin Pump Insertion Sites (along with their Type and Intensity) are presented below, from Baseline up to Week 39. Participants were asked to assess five different properties describing potential problems at the pump insertion site, namely "itching", "redness", "swelling", "heat" and "pain". Each of these questions could be answered with one of four alternatives, "None", "Minor", "Moderate" and "Severe".
