Technologie starten in risicostudie diabetes type 1 (STAR-T1D)

26 oktober 2026 bijgewerkt door: Estelle M. Everett, MD, MHS, University of California, Los Angeles

Startende technologie in het onderzoek naar diabetes type 1 (STAR-T1D).

Diabetes technology has revolutionized T1D management, disparities in technology access are evident among racial-ethnic minorities, patients with lower socioeconomic status and those with poorly controlled T1D (A1c>8.5%). In order to examine whether diabetes technology can reduce diabetes care burdens and enhance outcomes among some of highest need patients, diabetes technology clinical trials must be expanded beyond the very select populations included in studies thus far (ie., mostly White, higher SES). Therefore, the investigators propose to perform a pilot RCT of hybrid closed-loop insulin pump therapy (HCL) in 40 diverse adult patients with poorly controlled T1D (HbA1c ≥8.0%) from the largest academic and safety net health systems in the Los Angeles region to determine the feasibility of a RCT in this population and identify facilitators and barriers of effective use of closed loop insulin pump therapy in patients with poorly controlled T1D.

Wapens en interventies

Deelnemersgroep / Arm
Interventie / Behandeling
Experimenteel: Hybrid Closed Loop Insulin Pump System

Participants will meet 1:1 with our CDE for at least 6 sessions over 6 weeks. Sessions will cover self-management basics, carb counting, CGM interpretation, hypoglycemia and hyperglycemia management and troubleshooting device issues. The investigators will follow up with participants in 24 and 72 hours after CGM and insulin pump initiation, respectively, to answer any device related questions that may arise in between sessions.

Participants will follow up at intervals of 1-4 weeks throughout the study. During visits, the investigators will assess for adherence and adverse effects and evaluate device and safety issues associated with pump settings in the HCL arm. The investigators will repeat A1c at 12 weeks and 24 weeks and administer follow up questionnaires at 12 and 24 weeks.

Patients will be started on an automated insulin delivery system.

Geen tussenkomst: Control

Participants in the control arm will receive diabetes education at a similar frequency as the intervention group. Diabetes education for the control group will be a combination of in-person visits with the CDE and telephone brief diabetes education sessions.

Participants will follow up at intervals of 1-4 weeks throughout the study. During visits, the investigators will assess for adherence and adverse effects. The investigators will repeat A1c at 12 weeks and 24 weeks and administer follow up questionnaires at 12 and 24 weeks.

Treatment Burden and Satisfaction: Diabetes Distress
Tijdsspanne: 6 months

Assessing treatment burden through the Type 1 Diabetes Distress Assessment System T1DDAS, which comprises eight questions and evaluates ten prevalent sources of diabetes distress in adults with type 1 diabetes. The score indicates the level of diabetes distress reported by the respondent, with higher scores indicating greater intensity. The core scale scoring ranges 1 to 5. This scale assesses each of ten common Sources of diabetes distress for adults with type 1 diabetes: Financial Worries, Interpersonal Challenges, Management Difficulties, Shame, Hypoglycemia Concerns, Healthcare Quality, Lack Of Diabetes Resources, Technology Challenges, Burden To Others, Worries About Complications. The higher the score, the more impactful that Source is likely to be in contributing to diabetes distress for this individual with the minimum value being 1 and maximum value being 5.

6 months

Tijdsspanne: 6 months

Assessed treatment burden and satisfaction using the Insulin Treatment Satisfaction Questionnaire (ITSQ), consisting of 22 questions among 5 content clusters with a score from 0 to 100% where a higher score indicates greater satisfaction with insulin treatment. The scale explores perceptions of current insulin treatment and its impact on daily life.

Tijdsspanne: 6 months

Examined treatment burden and satisfaction employing the Glucose Monitoring System Satisfaction Survey (GMSS), comprising 15 questions divided into four subcategories: openness, emotional burden, behavioral burden and trust. Higher scores within each subcategory denote either greater satisfaction or burden, depending on the specific aspect assessed with the minimum value being 1 and maximum value being 5. The total scare has a minimum value of 1 and maximum value of 15 with higher scores indicating greater satisfaction. The scores are obtained by calculating the mean for each.

Assessed treatment burden and satisfaction using the Motivation and Attitudes towards Health Scale (MATCH), consisting of nine questions categorized into four subgroups: willingness to make changes, perceived ability to make or maintain changes, feeling changes are worthwhile, and overall mean/average of willingness, able, and worthwhile. Scores are calculated by determining the mean or average response within each category with higher scores meaning a better outcome.

WILLINGNESS: minimum value is 1 and maximum value is 5. ABLE: minimum value is 1 and maximum value is 5. WORTHWHILE: minimum value is 1 and maximum value is 5. TOTAL SCALE: minimum value is 1 and maximum value is 9.
