Study Results: Usability of a Predictive Low Glucose Suspend (PLGS) Feature on a Touchscreen Insulin Pump

Nov 10, 2017

Hypoglycemia can be a debilitating effect of insulin therapy. Predictive low glucose suspend (PLGS) systems are under development to help reduce the likelihood and duration of low blood glucose values for people using insulin pump therapy.

Last week, during a poster session at the 2017 Diabetes Technology Meeting in Bethesda, Maryland, we presented results from a Human Factors study validating the safety of the user interface of a PLGS feature as part of the t:slim X2™ Insulin Pump. This study was conducted in the hands of users, with and without insulin pump or CGM experience.

The study was conducted at four independent research centers in the United States and demonstrated a 99 percent success rate among study participants who, after initial training, performed a series of critical tasks using the PLGS system.

“This study demonstrates that the t:slim X2 System with PLGS requires minimal training and is easy to use, even for people without pump or CGM experience,” said Betsy Dokken, PhD, Director of Clinical Affairs (pictured above) at Tandem Diabetes Care. “We believe that the high success rate and minimal errors observed in this study highlight the importance of human factors research in insulin pump development, particularly with the introduction of automated insulin delivery algorithms.”

Usability is an important consideration for automated insulin delivery systems, and these findings demonstrate that the t:slim X2 System requires minimal training and is easy for participants to use, including those who are pump and/or CGM naïve. In addition, these findings support the effectiveness of online training for the t:slim X2 with PLGS system.
