Simultaneous Risk Factor Control Using Telehealth to slOw Progression of Diabetic Kidney Disease (STOP-DKD)

Study Overview
=================
Brief Summary
-----------------
Diabetic kidney disease (DKD) is associated with high rates of cardiovascular events and death. In addition, DKD is the major cause of end-stage renal disease (ESRD) in the United States. The purpose of this study is to prevent progression of kidney disease among patients with DKD and uncontrolled hypertension (HTN) using a tailored, telehealth intervention that simultaneously address medication management and modifies multiple risk factors through a combination of patient self-monitoring, behavioral therapies and education to optimize adherence and self-efficacy. Additional goals are to improve control of cardiovascular disease risk factors and reduce cardiovascular events and death. We hypothesize that patients with DKD and uncontrolled HTN who receive this intervention will have less progression, or a smaller decrease in kidney function, after 3 years when compared to the education control group.

Detailed Description
-----------------
A randomized, controlled trial to slow DKD progression: Using an innovative telehealth approach that is potentially scalable with demonstrable efficacy in reducing antecedents of kidney disease, including poor blood pressure, glucose, and lipid control Enrolling demographically diverse patients from local primary care clinics to allow applicability of our results to the general US population within existing delivery systems; and Targeting patients with moderate DKD (estimated glomerular filtration rate between 45-90 ml/min/1.73m2 with evidence of diabetic nephropathy) and uncontrolled HTN (blood pressure ≥140/90 mm Hg), accounting for about 20% of all patients with diabetes who disproportionately suffer from end-stage renal disease (ESRD), cardiovascular events, and death.

Design Details

Primary Purpose: Health Services Research
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Pharmacist Telehealth Intervention<br>Will receive a tailored multi-factorial clinical pharmacist-administered telehealth intervention, which includes medication management and behavioral-educational components. The intervention will occur monthly over 3 years. | Behavioral: Pharmacist telehealth intervention<br>* A tailored intervention with medication management and behavioral components. The behavioral modules may include, diet, exercise, weight, tobacco use, medication management, side effects, diabetes education, DKD/ HTN/ CVD risk and knowledge.Based on the patient's responses to a series of questions, there will be a provision of tailored feedback to reinforce evidence-based behavior for disease and lifestyle management.<br>|
| No Intervention: Education Control<br>Will receive educational material about management of kidney disease | |
