Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The 4T program encompasses: Teamwork, Targets, Technology, and Tight Range. These methods will help patients better manage their condition of Type 1 Diabetes with improved patient-reported outcomes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The goal of the 4T study is to implement proven methods and emerging diabetes technology into the investigator's clinical practice to sustain a tight glucose range from the onset of type 1 diabetes (T1D) and optimize patient-reported and psychosocial outcomes. The investigators will define a program (4T - Teamwork, Targets, Technology, and Tight Range) translatable to Pediatric Diabetes clinics in the United States that reduces HbA1c and T1D burden and improves patient well-being.

Study Design: This is a prospective, open-label, pragmatic research study. Two related studies will be performed. In Study 2, a cohort of new onsets (183) receiving the 4T new onset intervention designed to decrease the rise in HbA1c seen from 4 to 12 months but following a tapered (from weekly to monthly) remote monitoring schedule will be compared to internal (4T Pilot and 4T Study 1) and external contemporaneous controls (CMH and DPV).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* All individuals within one month of T1D diagnosis seen at the Stanford Children's Diabetes Clinic
* Individuals who plan to receive follow up care at the Stanford Children's Diabetes Clinic
* Individuals who agree to CGM data integration into the EMR for remote monitoring
* Age: six months to \< 21 years of age
* Patient or guardian must own and operate an Apple compatible device (e.g., iPhone or iPod Touch) to allow for the Dexcom app and CGM data transmission to the hospital server-based remote monitoring system.

Dr Prahalad's LPCH Auxiliary Fund grant (in addition to the R18) has resources to support iPod Touch/iPhone purchases for participants who do not have these.

o For the Exercise Ancillary study: 11 to \< 21 years of age (the activity tracker is not validated for younger children) English and Spanish-Speaking (Study 2)

Exclusion Criteria

* Diabetes diagnosis other than T1D
* Diagnosis of diabetes \> one month prior to initial visit
* Individuals with the intention of obtaining diabetes care at another clinic
* Individuals who do not consent to CGM use, CGM data integration, remote monitoring
* Individuals \> 21 years of age
