BD FlowSmart™ Subcutaneous Insulin Infusion Set User Preference and Claims Study
BD FlowSmart™ User Claims Study
Continuous Subcutaneous Insulin Infusion (CSII) via insulin pump therapy has been shown to improve quality of life and glucose control in many patients with diabetes opting for this treatment modality. Despite significant innovation and advancement in pump technology, insulin infusion sets have been an area where innovation has been significantly lacking with no clinical studies performed prior to product launches.
BD has developed a subcutaneous infusion set with FlowSmart™ Technology designed to address patient comfort, insulin delivery and flow interruptions. According to preliminary animal and clinical studies, this technology results in lower infusion pressure indicating more consistent insulin delivery.
The FlowSmart infusion set has been previously tested in prototype form with healthy non-diabetic subjects with the sets inserted by nurses, and with CSII-using patients who self-inserted the FlowSmart infusion set in a clinical research setting.
The purpose of this study is to determine if insulin pump users prefer using the BD FlowSmart infusion set compared to their current set with respect to insertion pain and wear comfort.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Comparative Infusion Set Insertion Pain
Time Frame: Comparative pain measure assessed at the end of Study Period 2, after 9-11 days use of each infusion set type
|
At the study visit after completing both study periods (Visit 3), subjects will use a 15 cm Visual Analog Scale (VAS) to indicate which insertion set was less painful to insert, the BD Flowsmart or their current infusion set.
Effects of infusion set type will be tested for statistical significance using linear mixed models adjusting for the effect of subject, study site and period.
The model will be used to generate a two-sided 95% confidence interval for the adjusted average pain rating using a multiple comparison approach.

Comparative Infusion Set Wear Comfort
Time Frame: Comparative pain measure assessed at the end of Study Period 2, after 9-11 days use of each infusion set type
|
At the study visit after completing both study periods (Visit 3), subjects will use a 15 cm Visual Analog Scale (VAS) to indicate which set was more comfortable to wear, the BD FlowSmart or their current infusion set.
Only if reduced Pain (outcome 1) for FlowSmart if achieved will wear comfort be further analyzed.
Effects of infusion set type will be tested for statistical significance using linear mixed models adjusting for the effect of subject, study site and period.
The model will be used to generate a two-sided 95% confidence interval for the adjusted average comfort rating using a multiple comparison approach.

Overall Infusion Set Preference
Time Frame: Assessed at the end of Study Period 2, after 9-11 days use of each infusion set type
|
At the study visit after completing both study periods (Visit 3), subjects will use a 15 cm Visual Analog Scale (VAS) to indicate their preference for the BD Flowsmart compared to their current infusion set based on their recent experience.
Effects of infusion set type will be tested for statistical significance using linear mixed models adjusting for the effect of subject, study site and period.
The model will be used to generate a two-sided 95% confidence interval for the adjusted preference rating using a multiple comparison approach.
