title: Use of CoZmonitor in youth with type 1 diabetes.
abstract: BACKGROUND
  The purpose of this study was to evaluate the effectiveness of directly integrating self-monitoring blood glucose (BG) information with insulin pump therapy on overall glycemic control.
  
  
  METHODS
  In this randomized trial, 34 youth with type 1 diabetes using insulin pump therapy were trained on the use of the Deltec Cozmo Insulin Pump. Seventeen were randomized to use the CoZmonitor Blood Glucose Module, a device that attaches to the back of the pump using FreeStyle technology to perform BG tests which read directly on the pump screen. The remaining 17 (control group) used a FreeStyle Flash meter, a stand-alone BG meter, for their BG testing. At baseline, 3 and 6 months, the subjects filled out a questionnaire, had a hemoglobin A1c (HbA1c) test, and had pumps and meters downloaded.
  
  
  RESULTS
  After 3 months of study, there were no changes in mean HbA1c (+/- SD) values for the experimental (8.7 +/- 1.1 to 8.6 +/- 1.1) or the control groups (9.1 +/- 1.4 to 9.2 +/- 1.5). There were also no significant differences in HbA1c values after 6 months. The average number of BG tests per day did not change significantly in either group during the study. After 3 and 6 months, the experimental group rated satisfaction with the use of the CoZmonitor at 4.4 and 3.8 (respectively) on a five-point Likert scale, with 5 being the most satisfied.
  
  
  CONCLUSIONS
  Although significant changes in HbA1c values or the number of BG tests were not found, use of the BG module had a positive level of satisfaction.
