Randomised controlled trial of a novel glucose monitoring system among adolescents

This study was a randomised controlled trial of novel flash continuous glucose monitors  (FreeStyle Libre) in a teenage population. The main objective was to determine whether adding this novel technology to usual care in adolescents (aged 13-20 years) with poorly controlled type 1 diabetes may lead to:
*improved glycaemic control;
*increased glucose monitoring behaviour; and/or
*improved quality of life in patients.

The 64 study participants were divided into two groups – one group used flash glucose monitoring, and the other used finger-prick monitoring.

Those who were given the flash glucose monitors more than doubled their glucose level monitoring frequency. However, the flash monitoring technology did not improved glucose control and quality of life significantly more than the control group after six months.

"Despite the improved glucose-checking technology, and overwhelmingly positive participant and family experiences, improving psychosocial outcomes will require more intensive methods" says Associate Professor Wheeler.
