How Parents' Confidence in Closed-Loop Systems Grows Over Time

A new study following families using the CamAPS FX hybrid closed-loop system found that while blood sugar improvements appear quickly, parents' trust and positive feelings about the technology build gradually—especially after living with it at home for over a year.

Key takeaways

Children aged 1–7 using CamAPS FX saw their average HbA1c drop from 7.3% to 6.8% during the clinical trial, with these improvements lasting through 18 months of home use
Parents' expectations and confidence in the system didn't shift much during the initial trial period, but increased significantly after 18 months of everyday use
The findings suggest that trust in automated insulin delivery systems develops through extended real-world experience, not just initial exposure

What the Study Looked At

Researchers followed 64 families with very young children (ages 1–7) who have Type 1 diabetes. The children used the CamAPS FX hybrid closed-loop system during a clinical trial phase, then continued using it at home for an additional 18 months. Scientists tracked both the children's blood sugar control and how parents felt about the technology as time went on.

Blood Sugar Results Came Quickly and Stayed Strong

When children started using the closed-loop system, their blood sugar control improved right away. Average HbA1c levels dropped from 7.3% at the start to 6.8% during the clinical trial—a meaningful improvement. Even more importantly, these benefits held steady over the 18 months of home use, showing that the system's benefits weren't temporary.

Parents' Confidence Took Longer to Build

While blood sugar improved quickly, parents' expectations and trust in the system followed a different timeline. During the clinical trial phase, parental expectations remained relatively unchanged—they stayed about the same as when families started. However, after 18 months of using the system at home, parents' positive expectations increased dramatically.

This pattern suggests that living with the technology day-to-day, troubleshooting real situations, and seeing sustained results over time helps parents develop genuine confidence in what closed-loop systems can do for their families.

What This Means for Families

For parents considering or newly starting a hybrid closed-loop system, this research offers a hopeful message: the benefits for blood sugar control appear quickly and last. At the same time, it's normal if you don't feel entirely confident or have high expectations in the first weeks or months. Trust and comfort tend to grow as you and your child live with the system and see how it works in your real life.
