Recently, a review article by the team led by Professors Guo Lixin and Pan Qi from Beijing Hospital was published in the journal Aging Med (Milton), interpreting the Chinese Guidelines for the Diagnosis and Treatment of Diabetes in the Elderly (2024 Edition). The review focuses on the principles, clinical benefits, and application challenges of relevant technologies, aiming to improve the long-term prognosis of elderly patients with diabetes. The first author of the article is Dr. Cai Qingyun from Peking Union Medical College.
Insulin pumps simulate physiological insulin secretion and deliver small doses of insulin continuously and controllably according to the patient’s diet and daily activities. They have evolved into intelligent continuous subcutaneous insulin infusion (CSII) devices. Multiple studies have confirmed that insulin pump therapy is safe and effective in elderly patients with diabetes. It not only improves glycemic control but also reduces the risk of onset and progression of retinopathy and proteinuria, as well as lowering cardiovascular events and all-cause mortality.
On this basis, sensor-augmented pumps (SAP) integrate continuous glucose monitoring, hypo- and hyperglycemia alerts, and trend prediction. Compared with multiple daily injections, SAP achieves greater reductions in HbA1c and glycemic variability, decreases insulin dosage, and significantly lowers the risk of severe hypoglycemia in elderly patients, especially nocturnal hypoglycemia.
Hybrid closed-loop (HCL) systems further simplify glycemic management for elderly patients with diabetes. The system continuously monitors glucose levels, intelligently calculates the required insulin dose based on real-time glucose data, and automatically infuses insulin, realizing closed-loop glucose control. Therefore, it is known as an “artificial pancreas” and can significantly reduce the burden of monitoring, decision-making, and operation for elderly patients. Existing studies show that HCL systems prolong time in range and reduce hypoglycemia risk, while improving patients’ mental status and quality of life.
In recent years, advances in meal detection technology and tubeless insulin pumps have further enhanced the intelligence of closed-loop systems. However, current evidence is mainly derived from populations with type 1 diabetes, and whether the findings can be generalized to elderly Chinese patients with type 2 diabetes remains to be verified. In addition, marked physiological and functional heterogeneity in the elderly, operational complexity, dependence on caregiver support, and high economic costs remain major barriers limiting the widespread use of hybrid closed-loop systems in elderly diabetic populations.
