New research from Washington State University, in collaboration with several institutions, has demonstrated that automated insulin delivery (AID) systems are both safe and effective for older adults with type 1 diabetes. The study challenges the common belief that older individuals would struggle with advanced medical technology. AID systems use sensors to continuously monitor blood sugar levels and automatically adjust insulin dosing without user intervention. The findings, published in NEJM Evidence, highlight significant improvements in glucose control and ease of use, even among those who have managed their condition with daily injections for decades.
The study addresses the misconception that older adults find it difficult to adopt new technologies. Researchers found that participants aged 65 and older adapted well to using AID systems. Despite requiring more initial technical support, these devices were perceived as easy to use and equally embraced by all participants, including those with mild cognitive impairments. This suggests that with appropriate training, older adults can effectively manage their diabetes using advanced technology.
In a randomized crossover trial involving 78 participants, two types of AID systems—a hybrid closed loop system and a predictive low glucose suspend system—were tested against a non-automated sensor-augmented pump. Participants used each device for 12 weeks under regular monitoring. Results showed that both automated systems significantly reduced the time spent with dangerously low blood sugar levels compared to the non-automated system. Notably, the hybrid closed loop system was most effective at maintaining blood sugar within the target range, achieving a mean time in range of 74%.
Beyond improving glucose management, AID systems offer numerous benefits for older adults with type 1 diabetes. These systems reduce the burden of managing a lifelong condition, providing real-time data and automatic adjustments that simplify daily routines. The study's focus on factors relevant to older adults, such as preventing hypoglycemia, underscores the importance of tailoring diabetes management strategies to this demographic.
Professor Naomi Chaytor, one of the principal investigators, emphasized that while onboarding took more effort for older adults, providers should not be discouraged. With proper support, older adults can confidently integrate AID systems into their lives. The study also highlights the discontinuation of predictive low glucose suspend systems in favor of more advanced hybrid closed loop systems, aligning with the trial's positive outcomes. Collaborative efforts from multiple institutions ensured comprehensive data collection and analysis, reinforcing the validity of the findings. This breakthrough paves the way for improved diabetes care, benefiting both patients and healthcare providers.
