Brief Summary
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 \>8.5%) 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.

Outcome Measures
Primary Outcomes (7)
Proportion of screened participants that are eligible
Eligible among screened, enrolled among eligible, excluded among screened (and why) based on screening, recruitment and enrollment data.
6 months
Proportion of enrolled participants that are randomized
Randomized among enrolled, and receiving allocated intervention among randomized.
6 months
Proportion of average time delay to enrollment
Average time delay from screening to enrollment.
6 months
Proportion of retention among participants randomized to the Intervention Group
Retention among participants receiving allocated intervention after being randomized and discontinued intervention among randomized.
6 months
Proportion of retention among participants randomized
Participants lost to follow-up among those initially randomized.
6 months
Proportion of retention among participants randomized
Retention rates by participants completing all research assessments among randomized.
6 months
Number of participants who adhere to assigned treatment
Treatment-specific adherence, Adherence to study protocol and Proportion of planned assessments that are completed. Fidelity, which pertains to guaranteeing that the intervention is delivered in accordance with the established protocol, will be summarized by study arms, and differences between arms will be examined using t-tests or two-sample tests of proportions as appropriate. Adherence, which relates to the extent to which participants follow the treatment and study protocol, as well as the proportion of planned assessments completed, will be summarized by study arms, and differences between arms will be examined using t-tests or two-sample tests of proportions as appropriate.

Study Arms (2)
Hybrid Closed Loop Insulin Pump System
EXPERIMENTALParticipants 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.
Control
NO INTERVENTIONParticipants 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.
Interventions
Patients will be started on an automated insulin delivery system.
