What the trial was testing
The trial enrolled 38 patients with type 1 diabetes. The study was sponsored by University of Cambridge and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
Researchers followed patients through treatment and into recovery, tracking the outcomes that mattered most for the disease being studied.
What the results showed
The automated system kept blood sugar in range 80% of the time versus 71% with standard pumps.
The lancet. Healthy longevity · 2022 · NCT04025762
These findings — that blood sugar stayed in healthy range with automated insulin delivery — were published in the The lancet. Healthy longevity and represent the headline result of the study.
Researchers tracked outcomes across 38 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with type 1 diabetes, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
If you're over 60 with type 1 diabetes and already use an insulin pump, this automated system could give you better control with less work. It adjusts your insulin every few minutes based on your glucose readings. The system is FDA-approved and available now — ask your doctor if it's right for you.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

This study aims to learn whether a cognitive behavioral intervention can improve lifestyle and glucose targets for adults with type 1 diabetes.
Insulin Pump vs Multiple Daily Injections of Insulin and Glyco-metabolic Control in Type 1 Diabetic Patients
The transition from the Pediatric clinic to the adult care is a challenging period for young adults with type 1 diabetes, due to the high risk of poor glycemic control. Achieving the glycemic target without hypoglycemia and/or large glucose excursions is of paramount importance for type 1 diabetic patients, who have high variability of daily glucose levels . Both insulin pump therapy and multiple daily injections of insulin are recommended strategy to achieve glycemic control in type 1 diabetes; however, no studies investigated the effects of insulin pump vs insulin injections on glycol-metabolic outcomes in the transition phase. The aim of this study was to evaluate the effects of continuous subcutaneous insulin infusion (CSII) therapy, as compared with multiple daily injections of insulin (MDI), on glycemic and metabolic control, in young type 1 diabetic patients transitioned to the adult diabetes care.
