Role of Mobile Technology to Improve Diabetes Care in Adults With Type 1 Diabetes: the REMOTE-T1D Study, a Pilot Study

Phase 4

Completed

• Conditions: Type 1 Diabetes
• Interventions: Device: iBGStar meter

• Registration Number: NCT01825382
• Lead Sponsor: University of Colorado, Denver

Brief Summary

The goal of this prospective pilot study is to evaluate the use of remote technology (iBGStar in combination with Diabetes Manager App on iPhone) to patient related outcomes, and a hypoglycemia fear questionnaire. In the future, this study might lead to investigating the role of social media with mobile phones in Type 1 Diabetes (T1D) care. Moreover, the number of patients with T1D continues to increase, and such technology could conceivably help compensate for the shortages of endocrinologists providing care.

Detailed Description

This is a single-center, prospective, randomized, 'open-label,' investigator initiated pilot study evaluating the role of mobile technology to improve diabetes care in adults with type 1 diabetes (REMOTE-T1D). We hypothesize that the use of mobile technology (iBGStar® technology \[iPhone® plus the BGStar®\]) will result in improvement in Patient Reported Outcomes (PRO), and Treatment Satisfactions with a possible reductions of glucose excursions, A1c, and severe hypoglycemia as compared to routine clinical care using traditional glucose meter SMBG-Accu-chek®. This study aims to demonstrate the efficacy of these technologies in a clinical setting with a hope to improve outcomes and health care cost savings.

The study will enroll 100 patients from the Barbara Davis Center Adult clinic over the age of 18 years who will be randomized in a 1:1 fashion to intervention group using mobile technology (iBG Star) vs. continued routine clinical care (control) using SMBG-Accu-chek meter. All subjects will be followed for study visits with similar frequency at baseline, 1-week, 1-month, 3-months, and 6-months and wear a continuous glucose monitor (CGM) using a DexCom SEVEN Plus® system in a blinded mode for 7 days at baseline (wk0), 1mo, 3mo, and 6mo.

Laboratory analysis for A1c will be performed at baseline, 1-month 3-months, and 6-months. Routine blood tests will be performed in all subjects at baseline, 3months, and 6-months. Blinded CGM data will be analyzed for mean blood glucose values, time spent in hyperglycemic (\>240, \>300mg/dl) and hypoglycemic (\<50, \<70, \<80 mg/dl) ranges and various indices of glycemic variability.

Arm && Interventions

Group	Intervention	Description
iBGStar meter interventional Arm	iBGStar meter	Subjects are given iBGstar meter along with iPhone to use as interventional meter.

Primary Outcome Measures

Name	Time	Method
Patient Reported Outcomes as it relates to hypoglycemia fear and quality of life.	6 months	Primary outcome is patient related outcomes and changes based on the hypoglycemia fear questionnaire and changes in patient comfort in meter use.

Secondary Outcome Measures

Name	Time	Method
Improvement in glucose control and indices off glucose variability from SMBG and CGM data.	6 months	Improvement in parameters of glycemic variability as measured by glucose excursions from SMBG and CGM downloads and various indices (J-index, mean amplitude of glycemic excursion (MAGE), high blood glucose index (HBGI), low blood glucose index (LBGI), from, CGM downloads. Reduction in A1c of 0.3% from screening to 3-months and maintained at 6-months, and reduction of hypoglycemia (measured or self reported). Cost analysis will be done based upon primary and secondary outcomes.
