Sensor and Software Use for Improved Glucose Control in MDI Managed Diabetes

Phase 4
Completed
Conditions
Diabetes Mellitus
Interventions
Device: FreeStyle Navigator
Device: Standard SMBG
Registration Number
NCT01713348
Lead Sponsor
Abbott Diabetes Care
Brief Summary

To understand if Multiple Daily Injections (MDI) managed subjects can improve glycaemic control by;

1. regularly checking and understanding Continuous Glucose data \& trend arrows at times other than the standard pre-meal bolus calculation test times and

2. review of their glucose profiles (inc. hypoglycaemic risks) with their Health Care Professional (HCP) and adjusting behaviours \& therapy from interpretation of the Continuous Glucose profiles.
