Every year, the Advanced Technologies & Treatments for Diabetes (ATTD) conference brings together diabetes researchers worldwide. In Amsterdam on March 19-22, 2025, data from the T1D Exchange Quality Improvement Collaborative (T1DX-QI) was shared in three oral presentations and one poster.

This study examined the impact of early initiation of automated insulin delivery (AID) on health outcomes in children and adolescents with type 1 diabetes (T1D). Using data from the T1D Exchange Quality Improvement Collaborative (T1DX-QI)’s EHR dataset, we analyzed outcomes two years after diagnosis among 44,665 children with T1D.
Our findings suggest that early adoption of AID improves longer-term diabetes management and reduces the risk for severe hypoglycemia and diabetes-related ketoacidosis (DKA).
We looked at when these children began using an AID system after their diagnosis and split them into four groups: “Early Users,” who began using AID within less than 6 months of their diagnosis; those who started AID 6-12 months post-diagnosis; “Late Users,” who began using AID 13-24 months after their diagnosis; and “Non-AID Users,” who did not use an AID system at two years after their diagnosis.
Compared to Late Users, we found that Early Users had:
Our results showed that Early Users had significantly better outcomes than Late and Non-AID Users.

This study compared emerging adults (18-23 years old) with type 1 diabetes receiving care in pediatric versus adult institutions.
Using data from the T1DX-QI, the researchers analyzed 8,538 young adults from pediatric centers and 839 from adult centers.
They found that the individuals in adult institutions generally:
This study highlights potential challenges during the transition to adult care and underscores the need for further research to address barriers to technology use in this population.

This study used EHR data for adults with type 1 diabetes to compare rates of DKA and severe hypoglycemia in those with and without chronic kidney disease (CKD).
The data showed that CKD in people with T1D is associated with a modest increase in DKA risk, while severe hypoglycemia risk remains similar after accounting for key demographic and treatment-related factors.
Out of 49,178 people with T1D, 3.2% had CKD. The group of people with T1D and CKD had an average age of 56.7 years, while the group without CKD had an average age of 30.4 years. The group of people with CKD also had a longer duration of T1D than those without CKD.
Unadjusted analyses showed increased rates of severe hypoglycemia among people with CKD. However, after adjusting for factors like age, sex, race/ethnicity, and technology use, the severe hypoglycemia rates were similar between both groups.
However, the adjusted analysis revealed a small but statistically significant increase in DKA rates among people with T1D and CKD.

Similar to the above presentation, this poster used our quality improvement collaborative’s EHR database to compare demographic characteristics and health outcomes between adults with T1D who have CKD and those who do not.
Here are the findings:
