Time in Target Blood Glucose Range
Tidsram: Day 1-15 compared with Day 60-74
|
Masked continuous glucose monitoring data will be collected for two weeks at the start of the study and 2 weeks at the end of the study.
Analysis will assess the difference between the assessment and baseline phase for the intervention group.
Target blood glucose range is 3.9 to 10.0mmol/l (70 to 180mg/dL)

Tidsram |
---|---|---|
HbA1c
Tidsram: Day 1 compared with Day 74
|
HbA1c will be tested at baseline (day 1) and then again at end of study (approximately day 74). The percentage of glycosylated hemoglobin in Diabetes Control and Complications Trial (DCCT) units was standardized to the newer International Federation of Clinical Chemistry (IFCC) units (mmol/mol). |
Day 1 compared with Day 74
|
Change in Diabetes Treatment Satisfaction Questionnaire (DTSQc) Scores From Day 1 to Day 60.
Tidsram: Day 60 compared to day 1
|
The Diabetes Treatment Satisfaction Questionnaire change (DTSQc) score is used to assess relative change in participant satisfaction from baseline. The questionnaire consists of 8 items, 6 of which (1 and 4 through 8) assess treatment satisfaction. Each item is rated on a 7-point Likert scale (-3 to +3). The scores from the 6 treatment satisfaction items are summed to a Total Treatment Satisfaction Score, which ranges from -18 (much less satisfied) to +18 (much more satisfied). There is one question to assess the change in satisfaction with perceived frequency of Hypoglycaemia and one question to assess change satisfaction with perceived frequency of Hyperglycaemia. Each question is rated on a 7-point Likert scale (-3 to +3), -3 (much less satisfied) to +3 (much more satisfied). The 95% confidence intervals for the FreeStyle InsuLinx group DTSQc scores was calculated using a one-sample t-test. |
