Key takeaways

Insulin pumps (CSII) may provide a small advantage in blood sugar control compared to multiple daily injections (MDI), but the difference is modest
Both methods appear equally safe—neither method significantly increased severe low blood sugar episodes or diabetic ketoacidosis
The evidence is still developing; researchers need more studies to draw definitive conclusions
The choice between pumps and injections should involve your care team and what works best for your family

The Question: Which Insulin Delivery Works Better?

Parents and young people with Type 1 diabetes often face an important decision: should they use an insulin pump (continuous subcutaneous insulin infusion, or CSII) or multiple daily injections (MDI)? A new systematic review examined 14 rigorous clinical trials involving 659 children to compare how well these two methods control blood sugar.

What the Research Found About Blood Sugar Control

The analysis showed that insulin pumps were associated with a slightly lower A1c compared to injections. However, when researchers looked at all the data together, the difference was small and didn't reach statistical significance in their main analysis. When they reanalyzed the data excluding one large real-world trial, they did find a meaningful advantage for pumps—about a 0.27% reduction in A1c.

To put this in perspective, an A1c difference of less than 0.5% is generally considered modest. This suggests that while pumps may help some children achieve slightly better blood sugar control, the improvement is not dramatic for everyone.

Safety: Are Pumps or Injections Safer?

One of the most important questions families ask is whether one method is safer than the other. The review found no significant differences between pumps and injections when it came to severe low blood sugar episodes or diabetic ketoacidosis (DKA), a serious complication. This means both delivery methods appear to carry similar safety profiles when used properly.

What This Means for Your Family

Researchers concluded that insulin pumps may offer a modest advantage in blood sugar control without increasing safety risks. However, they also noted that more evidence is still needed before drawing firm conclusions. The differences between methods are small enough that other factors—such as comfort, lifestyle, convenience, and what your child prefers—should play an important role in the decision.

The best insulin delivery method is the one your family can use consistently and that fits your daily life. Working closely with your diabetes care team will help you weigh the pros and cons for your specific situation.
