From June 5-8, 2026, researchers from T1D Exchange and the T1D Exchange Quality Improvement Collaborative (T1DX-QI) shared new findings at the American Diabetes Association's 86th Scientific Sessions, one of the world's largest scientific meetings focused on diabetes research and care.
The studies presented this year spanned many topics, including early detection of type 1 diabetes (T1D), diabetes technology, health equity, healthcare delivery, policy, and lived experiences.
Below are highlights from T1D Exchange research presented at the 86th Scientific Sessions.
1058-OR: Operationalizing Early-Stage Type 1 Diabetes Screening and Monitoring: A Pediatric Multicenter T1D Exchange Quality Improvement Initiative
As screening for type 1 diabetes (T1D) becomes more widely available, researchers are exploring how early detection can be incorporated into routine care.
A T1D Exchange Quality Improvement Collaborative (T1DX-QI) project was launched to increase early screening and monitoring for T1D at pediatric centers.
The initiative identified 194 people who screened positive for diabetes-related autoantibodies, including 48 meeting Stage 1 and 49 meeting Stage 2 T1D criteria. Those who qualified were offered monitoring and treatment options, and no cases of diabetes-related ketoacidosis (DKA) were reported.
These results demonstrate that screening and follow-up for early-stage T1D can be successfully incorporated into pediatric clinical care.
1305-OR: Emerging Type 1 Diabetes Screening and Intervention Programs: Insights from 63 Centers in the T1D Exchange Quality Improvement (T1DX-QI) Collaborative
Building on efforts to expand early detection, another study examined how diabetes centers are approaching T1D screening and preparing for therapies that may delay disease progression, such as teplizumab.
The survey found that screening programs are becoming more common, particularly in pediatric diabetes centers, but practices differ from one center to another. Many centers reported conducting diabetes autoantibody screening through research programs rather than as part of routine care.
The results highlight both the progress being made in early T1D screening and the work still needed to make screening and early intervention more widely available.
1873-P: How Specific Features May Shape the Shared-Decision Making Process Involved in Clinicians Recommending Automated Insulin Delivery (AID) Systems for People with Type 1 Diabetes (PwT1D): A Qualitative Study
A qualitative study of clinicians from 20 T1DX-QI centers found that protection from high and low blood glucose levels, along with integration of continuous glucose monitors (CGMs), were among the AID system features most likely to influence recommendations.
Clinicians said they take a personalized approach when discussing AID systems, with recommendations often influenced by age, lifestyle, and personal preferences. They also noted that access can be limited by insurance coverage, cost, smartphone connectivity, CGM compatibility, and language or literacy barriers.
1910-P: Increasing Adoption of Diabetes Technology among Adults with Type 1 Diabetes in a National Quality Improvement Collaborative: Results from T1D Exchange
Data from the T1DX-QI showed steady growth in technology adoption among adults with T1D between 2023 and 2025. CGM use increased from 69% to 77%, while AID use rose from 38% to 45%.
Participating centers evaluated and expanded strategies designed to improve access to technology. Their experience suggests that changes to center workflows, engagement efforts with their patients, and barrier reduction can help more people use CGMs and AID systems.
1985-P: Increasing Adoption of Diabetes Technology among Children and Youth with Type 1 Diabetes: T1D Exchange Quality Improvement Collaborative
Similar improvements were observed in pediatric care settings.
At 25 pediatric diabetes centers, CGM use increased from 83% to 91%, and AID system use grew from 58% to 64% between 2023 and 2025. This increase reflects ongoing efforts to help more children and teens use diabetes technology.
1911-P: Advancing Equity in Diabetes Technology: T1D Exchange QI Collaborative Multicenter Quality Improvement Project across Adult and Pediatric Centers
Expanding access to technology also means addressing disparities in who receives these tools.
A quality improvement project across nine T1DX-QI centers assessed ways to improve equitable access to diabetes technology. Centers used tools such as shared decision-making, interpreter support, clinician bias training, early education at diagnosis, and assistance with out-of-pocket costs.
All nine centers implemented interventions to increase CGM and insulin pump use, while three centers tested interventions to increase connected insulin pen use. Seven centers increased CGM and insulin pump use across racial and ethnic groups, while two of three centers increased connected insulin pen use. Five of the nine participating centers also narrowed gaps in technology use between Non-Hispanic White and Non-Hispanic Black populations, and between Non-Hispanic White and Hispanic populations.
2062-P: Practice Patterns for CGM Initiation after Diagnosis of Type 1 Diabetes in Pediatric and Adult Settings: A T1D Exchange Quality Improvement Collaborative Study
Researchers also examined how diabetes centers use CGMs and remote monitoring to support people newly diagnosed with T1D.
Most pediatric centers reported starting CGM use within the first few days after diagnosis, while adult centers were less likely to do so. Many centers were already using CGM data to support people between appointments, but few had standardized approaches to remote monitoring. Expanding these efforts could help provide more consistent support as people learn to manage T1D after diagnosis.
2878-LB: Trends in Automated Insulin Delivery Initiation among Newly Diagnosed Adults with Type 1 Diabetes: A T1D Exchange Multicenter Study
Another area of focus was helping people begin AID therapy sooner after diagnosis.
At five adult diabetes centers, more newly diagnosed adults were able to start AID systems within six months of their diagnosis. Additionally, average A1C levels were lower after people began using the technology.
These results show that quality improvement efforts can help more adults access diabetes technology earlier in their T1D journey.
2879-LB: Using Quality Improvement Strategies to Advance Early Automated Insulin Delivery Initiation in Pediatric Type 1 Diabetes: A T1D Exchange Multicenter Study
A similar approach was evaluated in pediatric diabetes centers.
Between 2024 and 2025, six participating centers reduced the time to AID initiation and increased the proportion of newly diagnosed children and adolescents who started using an AID system within six months of diagnosis.
The project focused on improving clinical workflows, providing education for families and care teams, and addressing insurance barriers, helping more young people access diabetes technology sooner.
2021-P: Describing the FTE of Diabetes Care Teams across the T1D Exchange QI Collaborative
Researchers surveyed participating diabetes centers to better understand the staffing resources available to support diabetes care and quality improvement efforts.
Staffing varied substantially across centers, with adult diabetes programs generally reporting fewer clinical and support staff than pediatric programs.
These findings provide a snapshot of the workforce supporting diabetes care and may help centers benchmark staffing levels, identify gaps, and plan future quality improvement initiatives.
2031-P: Correlation of Minoritized Ethnicity Representation between Patients and Staff of Diabetes Centers Involved in the T1D Exchange Quality Improvement Collaborative
Another study examined how well diabetes care teams reflect the communities they serve.
Across participating pediatric and adult diabetes centers, staff diversity was generally lower than diversity among patients at that center. Researchers also found that centers with more diverse care teams tended to serve more diverse populations of people with T1D, although this relationship was less clear among people with type 2 diabetes.
These findings highlight ongoing opportunities to strengthen diversity within the diabetes workforce and better reflect the communities receiving care.
2044-P: Using the Consolidated Framework for Implementation Research (CFIR) to Identify Barriers and Facilitators to Adoption of a Digital Quality Improvement Portal across a National Type 1 Diabetes Collaborative
Researchers evaluated a digital quality improvement portal designed to help diabetes centers review outcomes and learn from one another.
Centers reported challenges with data quality, training, and usability, but many found the portal useful for comparing performance and identifying areas for improvement. Their feedback helped guide updates to training resources, user support, and the portal itself.
2051-P: Diabetes Dietitians in Clinical Practice: Real-World Billing and Practice Data from the T1DX QI Collaborative
Nutrition support remains an important part of diabetes care.
Diabetes centers participating in the T1DX-QI were surveyed to better understand how dietitians are integrated into clinical practice. Most centers reported billing for dietitian visits, but approaches differed between pediatric and adult programs.
Pediatric centers were more likely to schedule dietitian visits alongside endocrinology appointments and to report that their patients had at least one dietitian visit each year.
2343-P: Common Barriers to Health Equity and Factors Actively Addressed to Improve Health Equity in the T1D Exchange QI Collaborative
An assessment of T1DX-QI centers identified common barriers to health equity, including limited access to diabetes technology, food insecurity, and transportation challenges.
Most pediatric centers reported actively addressing health equity and were more likely than adult centers to use structured approaches such as screening for social drivers of health, standardized documentation, and equity-focused education for trainees.
The findings suggest that system-level strategies may help support more equitable diabetes care and provide opportunities for shared learning across centers.
2908-LB: Formal Health Care Transition Policies among Adult and Pediatric Diabetes Centers in the T1DX-QI Collaborative
Researchers also examined how centers support young people transitioning from pediatric to adult diabetes care.
While most centers reported having a formal transition policy, more than one-third did not, and adult centers were less likely than pediatric centers to have one.
Because the transition to adult care can be challenging for young people with T1D, the findings point to opportunities for more consistent approaches across care settings.
2372-P: Lived Experiences with Menopause and Perimenopause in Type 1 Diabetes
Women with T1D who participated in a T1D Exchange Registry survey reported that menopause can make diabetes management more challenging, particularly due to sleep disruptions, weight changes, and changes in insulin needs.
Many participants said they felt unprepared for the transition and did not receive enough guidance or support from their healthcare team. By capturing the experiences of women in perimenopause, menopause, and post-menopause, this study highlights an area where more education, support, and research may help people with T1D better manage this stage of life.
2380-P: Agreement between Self-Reported and Laboratory-Measured HbA1c in the T1D Exchange Registry
A T1D Exchange study compared A1C values reported by Registry participants with A1C results measured in a laboratory.
Among more than 1,700 adults with T1D, self-reported and laboratory A1C values were highly consistent, including when determining whether someone was above or below the commonly used A1C target of 7.0%.
These findings show that people in the T1D Exchange Registry generally reported their A1C accurately, supporting the use of self-reported A1C data in research.
2381-P: International Comparison of Adjuvant Pharmacotherapy Use in Type 1 Diabetes 2018–2024
Researchers from T1D Exchange and the German/Austrian Prospective Diabetes Follow-up registry compared the use of type 2 diabetes medications as add-on therapies for people with T1D.
While use remained relatively uncommon overall, researchers found that prescriptions increased in the T1D Exchange Registry, particularly for GLP-1 receptor agonists. Use was most common among adults aged 40 and older.
The findings reflect growing interest in medications that may help with glucose management, weight, and other health outcomes in T1D, while underscoring the need for additional research in this area.
2905-LB: Economic Policy Impacts on Diabetes Programs in the T1D Exchange QI Collaborative
Researchers surveyed diabetes centers to understand how recent federal policy and funding changes may affect diabetes care programs.
Many centers identified Medicaid policies, changes to the Affordable Care Act, Medicare updates, and changes in hospital funding as factors that could affect financial stability. Several centers also expressed concern that federal budget cuts and reduced research funding could affect diabetes care and research efforts moving forward.
2917-LB: Prescribing Practices and Clinical Support for GLP-1 Receptor Agonists in Youth-Onset Type 2 Diabetes: Data from the T1DX QI Collaborative
Researchers surveyed pediatric diabetes centers to better understand how GLP-1 receptor agonists are being used in youth with type 2 diabetes.
While most centers reported that these medications were covered by insurance for many people, prescribing rates varied widely across centers. The survey also found that few centers had a structured plan for following up with people after they started taking these medications. This points to an opportunity to improve both access to GLP-1s and the support available once treatment begins.
