Clinical Trial Summary

In this project, the investigators will evaluate the efficacy of a novel approach to personalizing behavioral interventions for self-management of type 2 diabetes (T2DM) to individuals' behavioral and glycemic profiles discovered using computational learning and self-monitoring data. This study is a two-arm randomized controlled trial with n=280 participants recruited from the participating Federally Qualified Health Centers (FQHCs). The participants will be randomly assigned to the intervention group and the usual care (control) group with 1-1 allocation ratio. Half of the participants (n=140) will be randomly assigned to a usual care (control) group. Both groups will receive standard diabetes education at their respective FQHC site. In addition, the experimental group will receive instructions to use T2.coach for a minimum of 6 months.

Description:

One of the main difficulties in managing diabetes is that each affected individual requires personally tailored combination of diet, exercise, and medication to effectively control their blood sugar. Rather than strictly following a doctor's prescription, individuals need to carefully examine their lifestyle choices and their impact on their health. Independent learning, experimentation and problem solving become of great importance. However, they can be challenging for individuals with diabetes. In this project, the investigators will refine and evaluate a novel intervention for diabetes self-management that uses computational analysis of self-monitoring data to help individuals with type 2 diabetes identify what daily activities, including consumption of meals, physical activity, and sleep, have impact on blood glucose levels, and suggest modifications to these daily activities to improve blood glucose levels.

Growing evidence highlights significant differences in glycemic function and cultural, social, and economical circumstances of individuals with type 2 diabetes (T2DM) that impact their self-management. Precision medicine strives to personalize medical treatment to an individual's genetic makeup, computationally discovered clinical phenotypes and lifestyle. Studies showed the benefits of tailoring not only medical treatment, but also behavioral interventions. Yet, currently, personalization of self-management in T2DM requires each individual to engage in discovery, reflection, and problem-solving-critical but cognitively demanding activities-or to rely on their healthcare providers. Both of these may present considerable barriers to individuals from medically under-served low income communities. Mobile health (mHealth) solutions in T2DM bring promise of reaching wider populations in need of self-management; however, few such solutions provide assistance with personalizing self-management behaviors. Ongoing efforts on personalizing behavioral interventions outside of T2DM focus on tailoring behavior modification techniques to individuals' psycho-social characteristics, such as self-efficacy ), and tailoring delivery of intervention to individuals' context rather than on personalizing self-management strategies.

The ongoing focus of this research is on developing informatics interventions for diabetes self-management, with a specific focus on discovery with self-monitoring data and on problem-solving for improving glycemic control. In the proposed research the investigators introduce T2.coach, an mHealth intervention that uses computational analysis of self-monitoring data to identify behavioral patterns associated with poor glycemic control and formulate personalized behavioral goals for changing problematic behaviors. This study will evaluate T2.coach's efficacy in a two-arm RCT with stratified randomization conducted with Clinical Directors Network (CDN), a well-recognized primary care practice-based research network (PBRN) of Federally Qualified Health Centers (FQHCs), and Agency for Healthcare Research and Quality (AHRQ)-designated Center of Excellence (P30) for Practice-based Research and Learning.

Intervention

Behavioral:
• T2.coach
T2.coach is a smartphone app for low-burden capture of diet and blood glucose (BG) levels and for reviewing past records, integrated with FitBit for captured of physical activity and sleep. All captured data are sent to the computational inference engine that uses machine learning methods and expert system to formulate personalized behavioral goals. Examples of behavioral goals include the following: "For high carbohydrate breakfasts, reduce your carbs to be about 1 carb choice. Examples of 1 carb choice are 1 slice of whole wheat toast, 1 cup of oatmeal, or 1 apple." The T2.coach chatbot companion uses text messages to help individuals set goals that are consistent with evidence based guidelines for diabetes self-management, inferences on data captured with T2.coach, and their own preferences, as well as send individuals goal reminders and prompts for reflection on goal achievement.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in HbA1c value	Hemoglobin A1c	Baseline, 6 months, 12 months
Secondary	DPSI Score	Diabetes Problem-Solving Inventory (DPSI) is a 9-item, open-ended questionnaire. Answers are coded on a Likert 5-point scale (1-very poor strategy; 5-excellent strategy). The final score ranges from 1 (lowest) to 5 (highest) and an overall score =3 indicates poor diabetes problem solving, so a higher score indicates a better outcome.	Baseline, 6 months, 12 months
Secondary	SCA-I Score	Diabetes Self-Care Inventory (SCA-I) is a 15-item 5-point Likert scale (1-never engage; 5-always engage) for measuring different aspects of diabetes self-care. The final score ranges from 1 (lowest) to 5 (highest) with a higher score indicating better self-care (better outcome).	Baseline, 6 months, 12 months
Secondary	DSES Score	Diabetes Self-Efficacy Scale (DSES) is a 15-item 10-point Likert scale (1-not at all confident; 4-totally confident) that measures the belief that one can self-manage one's own health, adapted to diabetes. The final score ranges from 1 (lowest) to 4 (highest) with a lower score indicating poor self-efficacy (worse outcome).	Baseline, 6 months, 12 months
Secondary	PAID Score	Problem Areas in Diabetes (PAID) is a 20-item 5-point Likert scale (0-not a problem; 4-very serious problem) that measures the emotional aspect of living with diabetes. The final score ranges from 0 (lowest) to 80 (highest), with a higher score indicating greater emotional discomfort (worse outcome).	Baseline, 6 months, 12 months
