Brief summary

Observational study of patients at Boston Childrens Hospital with type 1 diabetes (T1D) who elected to treat their diabetes with the Medtronic 670 G hybrid closed loop insulin pump.

Detailed description

Outcome study of 90-100 patients with type 1 diabetes who elected to use the Medtronic 670G. Major outcome measure was to assess the percent of patients who were able to successfully continue to use the 670G technology over time. Additional outcome variables included hemoglobin A1c pre and post treatment with the 670G, time in desired glucose range 70-180.

Interventions

Design outcomes

Primary

MeasureTime frameDescription
Successful implementation of hybrid closed loop technology0-24 monthsPercent of Type 1 Diabetes patients who were properly trained on the use of the 670G that continue to use Hybrid Closed Loop technology at 0, 6, 12, 18 and 24 months post training.

Secondary

MeasureTime frameDescription
Impact of hybrid closed loop technology on glycemic control0-24 monthsAssess impact of hybrid closed loop technology on glycemic control by comparing hemoglobin A1c measurements 0-6 months prior to treatment versus 0-6, 6-12, 12-18, 18-24 months post treatment
Assess impact of hybrid closed loop technology on glycemic control by analysis of sensor glucose data.0-24 months.Compare sensor glucose data: 1) percent time in range (70-180 mg/dl), 2)percent time in auto-mode, 3) percent time sensor usage versus hemoglobin A1c data over time.
