Enhancing Informal Caregiving to Support Diabetes Self-Management

This study is ongoing, but not recruiting participants.

This study compares the medical and psychological effects of telemonitoring plus intensified self-management support to those of usual care alone for patients with poorly controlled type 2 diabetes mellitus (DM). If this intervention proves effective without increasing costs or clinician burden, then its implementation could yield major public health benefits, especially for vulnerable and underserved DM patients, and broader societal benefit may occur through increased helping behavior and strengthened social ties.

Condition Intervention
Type 2 Diabetes Mellitus
Behavioral: Telemonitoring + self-management support

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: Enhancing Informal Caregiving to Support Diabetes Self-Management

Further study details as provided by University of Michigan:

Primary Outcome Measures:
  • 12-month glycemic control [ Time Frame: 12 months ]
    H1 (Primary biological outcome): Compared to DM patients randomized to control, those randomized to intervention will have a 0.3% greater improvement in HbA1c units.

Secondary Outcome Measures:
  • Secondary effects upon adjustment to diabetes [ Time Frame: 12 months ]
    Compared to controls, intervention patients will have lower diabetes related distress.

Enrollment: 808
Study Start Date: December 2012
Estimated Study Completion Date: August 2017
Estimated Primary Completion Date: August 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Telemonitoring + self-management support
Automated assessment calls with follow-up by a Care Manager and a CarePartner for 12 months. Baseline, 6 month, and 12 month follow-up.
Behavioral: Telemonitoring + self-management support
Weekly automated assessment calls with follow-up by a care manager and a CarePartner for 12 months. Baseline, 6 month, and 12 month follow-up
No Intervention: Usual Care
Usual Care

Detailed Description:
Although in-home caregivers (ICGs) help improve diabetes mellitus (DM) outcomes, they may lack the resources needed to do this optimally, and are at risk for psychosocial decline and caregiver burnout. Complicating matters, millions of chronically-ill older Americans live alone and receive long-distance caregiving without any supporting structure or resources to ensure its effectiveness. In this study, diabetes patients with poor glycemic will be recruited from two clinical sites, and half will have an ICG. Patients will nominate a "CarePartner" (CP; adult relatives or friends from outside their home) to receive weekly email reports about their DM health and behavioral needs, and will be given resources to help them to provide self-management support. Patients will then be randomized to receive either one year of CP intervention or usual medical care. In the CP intervention arm, patients will provide weekly updates on their DM health and self-management through weekly automated telemonitoring. Summaries of this will be emailed to their CP along with guidance on helping the patient address reported problem(s), and their clinicians will be alerted about medically-urgent problems. We will assess the following outcomes in both arms before intervention and also after 6 and 12 months of intervention: glycemic control, DM-related distress, DM self-management, health-related quality of life, systolic blood pressure, caregiver burden, relationship quality, and cost of DM care.

Ages Eligible for Study:   21 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
