Telemedicine home-based management in patients with chronic heart failure and diabetes type II: study protocol for a randomized controlled trial

BACKGROUND: Heart failure and type 2 diabetes are prevalent public health issues in Europe. These complex chronic conditions require extensive pharmacological management, ongoing self-care, and behavioral changes. Despite the known benefits of lifestyle changes, such as regular exercise and better control of blood sugar levels, patients may need help implementing the recommended changes. This study aims to assess the effectiveness of a telemedicine program for managing heart failure and type 2 diabetes at home. The program focuses on promoting lifestyle changes. METHODS AND ANALYSIS: During scheduled outpatient cardiology evaluations, eligible patients are recruited and randomly assigned to either an intervention or control group in a 1:1 ratio. The intervention group receives support from a nursing case manager through a structured home-based teleassistance program and a trainer for daily physical activity stimulation. They also have access to teleconsultations with cardiologists and diabetes specialists as needed, telemonitoring of vital signs, and daily step tracking. An app records and monitors daily drug treatment, glycemia, blood pressure, heart rate, and other clinical parameters. Patients can also self-report symptoms and communicate via a chat and videoconference system with a Nurse Case Manager. The control group receives routine care. Data collection occurs before intervention and 6 months after baseline during a new outpatient cardiology evaluation. The primary outcome is to measure the difference in the distance walked during a 6-min walk test between baseline and after 6 months. The key secondary outcomes include improving the disease status and physical activity profile. Data will be analyzed according to the intention-to-treat principles. DISCUSSION: This study will provide evidence on the efficacy of a telemedicine home-based management model to maintain correct lifestyles in patients with both heart failure and type 2 diabetes, improving self-management, their empowerment on the diseases, and increasing their knowledge and ability to recognize symptoms early.
