How Older Adults with Type 1 Diabetes Are Finding Success with Automated Insulin Delivery

Managing Type 1 diabetes in older adults requires a careful balance. While maintaining healthy blood sugar levels is important at any age, older adults also face unique risks—including falls from low blood sugar episodes and other age-related health conditions. A new real-world study published in Frontiers in Endocrinology examined how well automated insulin delivery systems work for people over 60 and what settings help them achieve the best results.

The study looked at 97 adults aged 60 and older (average age 68) who were using the MiniMed 780G automated insulin delivery (AID) system. This system uses a continuous glucose monitor and an algorithm to automatically adjust insulin doses throughout the day, reducing the burden of constant manual adjustments.

Overall, the older adults in the study achieved good glycemic control. On average, they spent 76% of their time with blood sugar in the target range of 70-180 mg/dL—a benchmark many diabetes teams consider successful. Even more impressively, more than half the group (56.7%) spent at least 50% of their time in a tighter target range of 70-140 mg/dL.

Perhaps most important for safety, the group spent only 1.1% of their time with dangerously low blood sugar—a significant concern for older adults, who may not recognize hypoglycemia symptoms and are at greater risk of serious complications from low blood sugar episodes.

The MiniMed 780G system comes with manufacturer-recommended standard settings: a target glucose of 5.5 mmol/L (99 mg/dL) and an active insulin time of 2 hours. However, only 14 participants (14.4%) actually used these exact recommended settings. The rest customized their algorithms based on their individual needs.

Interestingly, blood sugar outcomes were similar whether users followed the recommended settings or made adjustments. This suggests that automated insulin delivery systems work well for older adults regardless of which specific algorithm settings they use—as long as those settings are personalized to their circumstances. This flexibility may be especially valuable for older adults managing multiple health conditions or taking other medications that affect blood sugar.

This study provides reassuring evidence that automated insulin delivery can help older adults achieve strong glycemic control while minimizing dangerous low blood sugar episodes. The key finding—that customized settings work as well as standard recommendations—emphasizes the importance of working with your diabetes care team to adjust your system settings to match your individual health needs and lifestyle.

If you're an older adult with Type 1 diabetes considering or already using an automated insulin delivery system, these results suggest that the technology can be an effective tool. However, success depends on regular communication with your healthcare provider to fine-tune your settings and monitor how well the system is working for you.
