Summary

This trial investigates if using mobile devices to monitor health and getting support from nurses can help people with poorly controlled diabetes and high blood pressure who haven't improved with regular treatments.

Who is the study for?
This trial is for adults with uncontrolled high blood pressure and type 2 diabetes, who have had poor management of these conditions over the past year. Participants must be able to give informed consent, speak English, use a smartphone, and have been seen at the primary clinic site in the last year. Pregnant individuals or those living in nursing homes are not eligible.
What is being tested?
The study is testing two programs: EXTEND and EXTEND Plus. Both involve using mobile devices for monitoring health and receiving nurse support to see if they help patients better manage their diabetes and hypertension on their own.
What are the potential side effects?
Since this trial involves technology use and nurse support rather than medication, traditional side effects are not applicable. However, participants may experience issues related to technology use such as privacy concerns or stress from constant health monitoring.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: EXTEND PlusExperimental Treatment1 Intervention
EXTEND Plus participants receive 4 mobile monitoring devices to facilitate chronic disease self-management (glucometer, BP cuff, scale, accelerometer). Device data are transferred to Duke University Health System (DUHS) for use as part of nurse-delivered intervention combining mobile monitoring, self-management support, and medication management. The intervention is administered by clinical registered nurses (RNs) from Duke Primary Care (DPC) or Duke Endocrinology. For the medication management component, RNs work with a study PharmD affiliated with the participant's clinic. The PharmD determines if medication changes are needed, and prescribes accordingly. The RNs deliver EXTEND Plus via scheduled telephone encounters throughout the 12-month intervention. The initial encounter frequency is every two weeks, but may be extended to every four weeks for patients achieving treatment goals.
Group II: EXTENDActive Control1 Intervention
EXTEND participants receive 4 mobile monitoring devices to facilitate chronic disease self-management (glucometer, BP cuff, scale, accelerometer). Device data are transferred to Duke University Health System (DUHS). Participants can review data and trends within the device apps and modify self-management practices accordingly. The EXTEND group continues chronic disease care with their existing providers during the study, and are instructed at baseline to address management questions via their primary clinics' established avenues (as would be the case for any patient using mobile monitoring in clinical practice).

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
The most common treatments for Type 2 Diabetes include metformin, sulfonylureas, insulin, SGLT2 inhibitors, and GLP-1 receptor agonists. Metformin works by reducing glucose production in the liver and improving insulin sensitivity. Sulfonylureas increase insulin secretion from the pancreas. Insulin therapy directly supplements the body's insulin levels. SGLT2 inhibitors prevent glucose reabsorption in the kidneys, leading to glucose excretion in urine. GLP-1 receptor agonists enhance insulin secretion, inhibit glucagon release, and slow gastric emptying. These mechanisms are crucial for Type 2 Diabetes patients as they help manage blood glucose levels, reduce complications, and improve overall health. Real-time health tracking and professional guidance can optimize these treatments by providing timely adjustments and personalized care, enhancing their effectiveness and patient outcomes.
