NCT01586065

Brief Summary

The purpose of this study is to see if children and adolescents with poorly controlled type 1 diabetes will benefit from using a continuous glucose monitor (CGM), a device that can be used to check blood sugars.

Outcome Measures

Primary Outcomes (1)

  • Number of High Glucose Correction Doses Administered.

    Principal study outcome was comparing insulin doses using pre- and post-meal sensor versus plasma glucose values. All insulin dose calculations over a 24-hour period were made using sensor glucose concentrations; these doses were compared to the those calculated as if plasma glucose were to be used instead for dose calculations.

    24 hrs

Secondary Outcomes (1)

  • Pre- and Post-meal (2-3 Hour) Glucose Levels

    24 hours

Study Arms (1)

CGM in adolescents with poorly-controlled T1D

EXPERIMENTAL

Adolescents with poorly controlled type 1 diabetes on insulin pumps were admitted to the clinical research center (CRC) and a continuous glucose sensor was inserted. Sensor glucose (SG) values were compared to plasma glucose measured at least hourly using Yellow Springs Instrument's (YSI) glucose analyzer. SG rather than YSI was used for treatment decisions unless YSI was \<70 mg/dL or specific criteria indicating SG and YSI were very discordant were met.

Device: Continuous Glucose Monitor (CGM)

Interventions

CGM during 24-hr CRC stay.
