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.

What are insulin pumps?

Insulin pumps are small, wearable devices programmed with individualized settings to deliver insulin into the body at numerous intervals throughout the day and night.

How do automated insulin delivery systems and insulin pumps work?

Automated insulin delivery systems
  • 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
  • Used in place of multiple daily injections (MDI) of insulin

Insulin pumps
  • 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 potential benefits?

Automated insulin delivery systems
  • 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

Insulin pumps
  • 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

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.)

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.)

More T1D tech


CGMs are small, wearable devices that continuously measure a person’s blood-glucose levels. They are used in place of finger sticks.



Smart insulin pens and pen caps are used to track insulin doses for people who take multiple daily injections (MDI) of insulin.
