Brief Summary

Feasibility study to compare the effectiveness of the Paradigm Sensor Augmented System versus subjects continuing to administer insulin in multiple dose injections. Evaluate the educational materials and time required for training subjects naïve to continuous subcutaneous insulin infusion (CSII) to use the Paradigm 722 REAL Time System in preparation for a large multi-center clinical trial

Detailed Description

Many subjects with Type 1 diabetes continue to manage their disease utilizing multiple daily injections, but despite frequent blood glucose checks, are unable to control their glycemic variability or lower their A1C levels. The MiniMed Paradigm REAL-Time System transmits sensor glucose values to the insulin pump every 5 minutes, allowing users to view their current glucose values as well as glycemic excursions and trends over a 24-hour period. The System will also alert users of high and low glucose levels, allowing subjects and their clinicians to make carefully monitored modifications to therapy. Additionally, data can be uploaded from the monitor into a personal computer, allowing the subject and clinician to see a complete picture of trends over time.

Subjects learning this technology would require a new approach to training if they were to master operation of an insulin pump, make effective use of the sensor technology and understand the complete picture provided by the software component. Subjects will be trained to first use the insulin pump, add the sensor and then utilize the software and the effectiveness of the training methods and timing will be measured using questionnaires designed to evaluate understanding of the device, Self Efficacy and User Acceptance. The group wearing the System will also be compared to subjects that continue on their current MDI therapy over a 15-week time period.
