The Next Step for Artificial Pancreas Technology: Moving Toward Full Automation

Automated insulin delivery systems have already helped millions of people with type 1 diabetes, but researchers say the technology could do even more if devices required less input from users. A new review examines what barriers still need to be overcome.

Key takeaways

Current artificial pancreas systems work well but still require users to manually input information about meals and exercise to prevent dangerous blood sugar swings
These devices perform best overnight when there are no meals or exercise to account for, highlighting a gap in daytime automation
Full closed-loop systems—devices that require little to no user interaction—are the goal researchers are working toward
Artificial pancreas technology is not yet available for all populations, including pregnant women and older adults

How Today's Artificial Pancreas Systems Work

Automated insulin delivery (AID) systems, including the artificial pancreas developed by UVA Health, have made a real difference for many people with type 1 diabetes. These devices automatically adjust insulin doses throughout the day and night, helping users maintain more stable blood sugar levels and improving their overall health.

However, current AID systems are not yet fully automated. Users still need to manually tell their device about meals they're eating and exercise they're doing. This requirement exists because the system needs this information to prevent dangerous blood sugar spikes or drops in response to these activities.

Where Current Systems Perform Best—and Where They Fall Short

AID systems work exceptionally well overnight, when users are sleeping and there are no meals or exercise to account for. But daytime management—when meals and physical activity happen—still requires active participation from the person using the device.

This limitation means that while the technology has successfully reduced some burdens of diabetes management, it hasn't yet eliminated the need for users to stay engaged with their care throughout the day.

The Vision: Fully Automated Systems

Researchers at the University of Virginia Center for Diabetes Technology are focused on creating the next generation of these devices: fully automated, or closed-loop, systems. The goal is to develop artificial pancreas technology that requires minimal or no input from users.

According to Dr. Sue A. Brown, an endocrinologist at the center, "These automated insulin delivery devices have significantly helped people with type 1 diabetes manage their blood sugars and yet challenges still remain. These newer approaches can help alleviate those requirements and we are hopeful that we can make insulin management even easier for people with type 1 diabetes."

Who Can Access These Devices Today

While artificial pancreas technology has benefited many people, it's not yet available or suitable for everyone with type 1 diabetes. Current systems have not been developed or tested for use by pregnant women or older adults, leaving these populations without access to this technology.

Expanding the availability of AID systems to all populations with type 1 diabetes remains an important area for future research and development.
