Effects of a Remote Patient Monitoring Protocol on Glycemic Control in Adolescents With Type 1 Diabetes


This study will use a randomized, crossover design. Children aged 13-18 years who have been diagnosed with Type 1 diabetes for at least 1 year and with at least 2 Hemoglobin A1c values ≥10.0% more than 60 days apart within the past year, with the most recent HbA1c value between 10-14%, will be placed into two separate treatment groups. Group A will undergo home monitoring for 12 weeks through the use of the Vivify kit, which contains a wireless tablet with daily medication/diet/symptom questionnaires. Group B will initially continue diabetes management per standard of care, including quarterly office visits. After a period of 12 weeks, Group B will switch to the RPM protocol, while Group A will return to standard of care. Both groups will have HbA1c values checked at the 0, 3, and 6 month time periods to assess the effect of the remote monitoring protocol. Participation in the RPM protocol will involve daily completion of the Care Plan questions, as well as weekly uploads of blood glucose values using the Glooko, Inc (Mountain View, CA) application, and weekly video visits with a member of the endocrinology team that will aim to address barriers to optimal care, whether they be motivation, knowledge or other difficulties. Barriers to care will be assessed in part through the completion of knowledge and self-efficacy assessments.

Detailed Description

RPM Software The Remote Patient Monitoring application that will be used for this study was created by Vivify Health. Vivify Health was founded in 2009, and their Remote Care Management platform utilizes consumer electronics and wireless health devices that patients can use easily from home. Using this platform, providers can create customized care plans for patients, as well as provide education through multimedia and face-to-face interaction through video conferences.

The Glooko mobile application allows patients to download diabetes data, including blood sugar readings, directly from their meter to compatible iOS and Android devices. The data can then be uploaded by the patient and viewed by providers.

Subjects Prospective study participants will be screened for by review of HbA1c values of patients with upcoming Endocrine clinic appointments, or during diabetes-related hospital admissions. Qualifying patients will be invited to participate in the study and written consent will be obtained from their parents (and assent from patients 10 years of age and older) prior to their randomization. Patients agreeing to participate in the study will be randomly assigned using sealed, blinded envelopes to Group A or Group B. Each group will have 25 patients.

Pre-Study Measurements Both groups will have HbA1c measured at the pre-study clinic visit or hospital admission as part of standard of care. After consenting to participation, each subject will schedule a brief telephone check-in with an investigator within 1 week of the initial encounter. Successful adherence to this telephone appointment will be used as a barometer of ability to follow through on scheduled remote communications, and will be required for randomization. After completing the telephone check-in, each patient will return within 2 weeks of the initial encounter. At this visit, randomization will occur, and they will complete 2 questionnaires at the beginning of the study: one knowledge assessment (the Diabetes Knowledge Test 2 (DKT2)) [15] and one assessment of self-efficacy (the Self-Management of Type 1 Diabetes in Adolescence (SMOD-A)) [16].

Intervention Groups Group A will be taught the remote monitoring expectations and will receive training on how to use the Vivify RPM software at the same visit that randomization occurs. Subjects in this group will be enrolled in the RPM protocol for the first 12 weeks of their participation in the study. While on the RPM protocol, subjects will be required to complete the Care Plan questions on a daily basis. They will also have scheduled video conferences with study team physicians or advanced practice nurses on a weekly basis, and will be expected to upload their blood glucose readings to Glooko each week for review. A web-based provider dashboard will allow the study team to monitor patients' usage of the software on a daily basis. Video visits are anticipated to last 15-20 minutes. During this time the study team will review the data collected during the previous week, discuss ongoing diabetes management and any barriers to care, and review selected diabetes self-management educational topics with study participants. The Care Plan questions, Weekly Conference questions, and Educational Objectives intended to be covered during the video visits are appended to the end of this document. Patients in Group B will complete all pre-study measurements at randomization, but remain on a quarterly visit schedule as per standard of care for the first 12 weeks of their participation in the study.

After the first 12 weeks, patients in Group A will return to quarterly office visits with their endocrinology team as per standard of care while patients in Group B enter into the RPM protocol. Both groups will have a clinic visit with HbA1c checked, and will complete the DKT2 and SMOD-A questionnaires for the 2nd time.

The study will conclude with the 6 month visit for both groups. Both groups will have a HbA1c checked, and will complete the post-study DKT2 and SMOD-A questionnaires for the 3rd and final time.


  • Behavioral: Vivify Health RPM Protocol
    • The Vivify RPM Protocol includes a wireless tablet and glucometer/Bluetooth device that can directly upload blood glucose readings to the tablet. Patients will daily Care Plan questionnaires on the tablet, as well as upload blood glucose readings twice a day. The tablets will also be used for weekly video conferences with study investigators.

Arms, Groups and Cohorts

  • Experimental: Intervention Arm
    • Patients will use the Vivify Health RPM protocol as part of their diabetes management. They required to complete the Care Plan questions on a daily basis, and will upload blood glucose readings directly to the tablet twice a day. They will also have scheduled video conferences with study team physicians or advanced practice nurses on a weekly basis, to discuss ongoing diabetes management and educational objectives.
  • No Intervention: Control Arm
    • Patients in this arm will manage their diabetes at home per normal standard of care, without any extra intervention from the study investigators.

Clinical Trial Outcome Measures

Primary Measures

  • Hemoglobin A1c
    • Time Frame: 3 months
    • To determine whether 12 weeks of participation in a remote monitoring protocol utilizing remote glucose data uploads and video visits through a mobile device improves glycemic control as measured by Hemoglobin A1c in adolescents with poorly controlled Type 1 Diabetes.

Secondary Measures

  • Diabetes Knowledge Test 2 (DKT2) score
    • Time Frame: 6 months
    • To determine whether 12 weeks of participation in a remote monitoring protocol can improve diabetes knowledge as assessed by a questionnaire in adolescents with poorly controlled Type 1 Diabetes. The DKT2 contains 2 sections, with 23 questions total. The first section is general knowledge, and has 14 items. The second section is an insulin-use subscale, with 9 items. Higher scores are better for both sections.
  • Self-Management of Type 1 Diabetes in Adolescence (SMOD-A) score
    • Time Frame: 6 months
    • Scoring: The first subscale (items 1-13) is Collaboration with Parents. Items 2 and 3 are reversed scored. The range of scores is 0 to 39. Higher scores indicate more collaboration. The second subscale is Diabetes Care Activities (items 14-28). Items 16, 21, 22, 23, 25, 26 are reversed scored. The range is 0 to 45. Higher scores indicate better performance of diabetes tasks. The third subscale is Diabetes Problem-Solving (items 29-35). Range of scores is 0 to 21. Higher scores indicate better problem-solving. The fourth subscale is Diabetes Communication (items 36-45). The range of scores is 0 to 30. Higher scores indicate more communication. The fifth subscale, Goals, is composed of items 1-7 of Part II of the instrument. The range of scores is 0 to 21. Higher scores indicate more goals. Calculating a total score is not recommended.
  • DKA Admission Rates
    • Time Frame: 6 months
    • To evaluate whether usage of the remote monitoring protocol affects hospital admission rates for adolescents with poorly controlled Type 1 Diabetes.
