Insulin Pump Therapy for Patients with Poor Glycemic Control

Introduction to Automated Insulin Delivery Systems

The American Diabetes Association recommends automated insulin delivery (AID) systems for patients with inadequate glycemic control, as these systems provide superior glycemic control compared to non-automated pumps and can reduce A1C by an additional 0.30% while significantly improving time in range 1, 2

Patients with blood sugars consistently >200 mg/dL and an insulin requirement of 50 units daily may benefit from pump therapy, according to the American Diabetes Association's guidelines 6, 7
The American Diabetes Association specifically recommends considering insulin pump therapy for adults and youth with type 2 diabetes who are on multiple daily injections and able to safely manage the device 4
Before starting pump therapy, patients must demonstrate carbohydrate counting proficiency, frequent glucose monitoring capability, technical aptitude, and high motivation 6, 7, 8

Patients using insulin pumps are at risk for rapid ketoacidosis in case of complete pump failure, and must always carry rapid-acting insulin syringes or pens as backup 4, 6, 9
Initial pump settings should be calculated from the current total daily dose, with approximately 50% of total daily insulin delivered as continuous hourly infusion and the remaining 50% divided among meals based on carbohydrate-to-insulin ratio 7
Close monitoring is necessary during the first 3 months, with daily contact to adjust basal rates and troubleshoot issues, and weekly to biweekly visits for fine-tuning settings and addressing concerns 2

Pump therapy adoption shows significant disparities based on race/ethnicity, insurance status, and income, and socioeconomic barriers should be addressed upfront 3, 4, 5
For a patient using 50 units daily, verify adequate reservoir capacity, with most insulin pumps holding 200-300 units and providing 4-6 days of insulin 3
