Automated Insulin Delivery Systems for Older Adults: What the Evidence Shows

Automated insulin delivery (AID) systems—often called artificial pancreas systems—have changed how many people manage Type 1 diabetes. They work by continuously monitoring blood sugar and automatically adjusting insulin delivery throughout the day and night. For decades, these systems have been studied and refined, but most research has focused on younger adults and teenagers.

As people with Type 1 diabetes live longer, a critical question has emerged: Do these systems work as well in older adults? A comprehensive review of current research, published in the journal Endocrine, found that while the evidence is promising, significant gaps remain in our understanding of how AID systems perform in people 65 and older.

Studies in younger populations have consistently demonstrated that AID systems improve time in range—the amount of time a person's blood sugar stays between 70 and 180 mg/dL, the target range—and reduce episodes of dangerous low blood sugar (hypoglycemia). The review found that available evidence in older adults suggests these benefits may also apply to this age group, particularly when it comes to reducing low blood sugar events.

However, the researchers caution that the evidence base for older adults remains limited compared to what we know about younger populations. Older adults have been significantly underrepresented in the clinical trials that have tested these systems, which means we cannot yet be certain how broadly these benefits apply.

The research reveals that whether an automated system works on paper is only part of the story. Real-world success depends on whether people can actually use the technology in their daily lives. For older adults, several factors can interfere with successful adoption and use of AID systems.

Cognitive changes—such as difficulty with memory or decision-making—can make it harder to manage the system. Physical limitations might affect someone's ability to handle the small devices or navigate their touchscreens. Lower comfort with digital technology, sometimes called digital literacy, is another common barrier. Additionally, some older adults may depend on caregivers for help, which requires coordination that isn't always straightforward.

The review notes that frail individuals and those managing multiple chronic health conditions have been largely left out of clinical trials. This means we have very little evidence about how AID systems work for the oldest and medically most complex older adults who might benefit from them most.

The bottom line from this research is that AID systems appear to be both effective and safe for many older adults with Type 1 diabetes—but with important caveats. The technology itself seems to deliver the same kind of blood sugar improvements and safety benefits seen in younger people. However, not every older adult will be a good candidate, and success depends on factors beyond the system's technical performance.

Healthcare providers working with older adults need to carefully assess each person's individual situation, including cognitive abilities, physical function, comfort with technology, and social support. As research continues, experts emphasize the need for larger, more diverse studies that specifically include older and frailer adults, so we can better understand how to implement these systems effectively across the full spectrum of the aging population with Type 1 diabetes.
