Automated insulin delivery systems and insulin pumps
What are automated insulin delivery systems?
An automated insulin delivery (AID) system has three main components: an insulin pump, a continuous glucose monitor (CGM), and an algorithm that determines the best insulin dose to help keep you in range. AIDs are also known as artificial pancreas or closed-loop systems.

How do they work?
- Measure blood-glucose levels and adjust insulin delivery automatically
- Give less insulin when blood sugar is low and more insulin when blood sugar is high
- Not completely automated and still require user input for meals and snacks and troubleshooting
- Are used in place of multiple daily injections (MDI) of insulin
What are the benefits?
- Requires fewer decisions/calculations because the system does much of it for you
- Fewer highs and lows, especially overnight
- Fewer finger sticks and injections
- Has been shown to improve time-in-range, especially during sleep
Other things to consider about automated insulin delivery systems
- Requires wearing two devices at all times
- More alerts and alarms can cause “alarm fatigue” for some
- You still need to practice daily T1D management (carb counting, bolusing, adjusting for exercise, etc.)

Learn more about insulin pumps
How do insulin pumps work?
- Automatically deliver a small, steady flow of insulin 24 hours a day (basal insulin), and the person wearing the device can deliver additional doses of insulin (called boluses) to cover meals and treat high blood sugar as needed
- Programmed to meet the individual needs of the person using it
- Insulin is delivered through a small cannula that is inserted under the skin with a needle. Common insertion sites on the body include the thighs, buttocks, abdomen, upper arms, and other locations where insulin can be injected.
- Used in place of multiple daily injections (MDI) of insulin
What are the benefits?
- Fewer injections
- Makes administering insulin easier (compared with traditional injections)
- Easy to use on-the-go
- Has a built-in dosing calculator
Other things to consider about insulin pumps
- Setting it up and getting used to it can take some time
- It needs to be worn all the time
- You still need to practice daily T1D management (carb counting, bolusing, adjusting for exercise, etc.)
