Automated Insulin Delivery in Older Adults: Why Time in Range Alone Isn't the Whole Story

A new study published in the Journal of Diabetes Science and Technology examined how automated insulin delivery systems work for older adults living with Type 1 diabetes. While these systems are effective at keeping blood sugar in target range more often, the research raises an important question: Is maximizing time in range the right goal for everyone?

The findings suggest the answer isn't straightforward. Older adults have different health needs, different levels of independence, and different priorities than younger people. What works best for one person may not be ideal for another, even if both have Type 1 diabetes.

Time in range—the percentage of time blood sugar stays within a target zone—is an important measure of diabetes management. But it's not the only measure that matters. For older adults, other factors can be equally or even more important.

Reducing the risk of low blood sugar, maintaining energy and mental clarity, avoiding frequent alarms and notifications, and fitting treatment into daily life all matter. A system that keeps someone in range 90% of the time but causes constant worry or disruption might not be better than one that achieves 85% time in range while giving someone peace of mind.

The research underscores an important principle: diabetes management goals should be tailored to each person. For some older adults, the highest possible time in range makes sense. For others, a slightly lower target might be more appropriate if it means fewer lows, less stress, or better quality of life.

Healthcare providers working with older adults using automated insulin delivery should discuss what matters most to each person. This conversation should include questions about fear of low blood sugar, comfort with technology, daily routines, and how much time someone wants to spend thinking about diabetes management.

As automated insulin delivery systems become more available and more advanced, the research suggests that success shouldn't be measured by a single number. Instead, it should reflect whether the system helps each older adult live well with Type 1 diabetes in a way that works for their unique situation.

If you or an older adult you care for uses or is considering an automated insulin delivery system, talking with your healthcare team about what 'good control' means for your specific circumstances is an important step.
