Telemedicine-Based Behavioral Intervention to Improve Self-Care Among Hypertensive Patients

The goal of this quasi-experimental clinical study is to learn whether a telemedicine-based behavioral intervention can improve self-care practices among adult patients with hypertension receiving care at teaching hospitals in Northwest Amhara.

The main questions it aims to answer are:

* Does a telemedicine-based intervention improve self-care practices among hypertensive patients? * Does the intervention improve medication adherence among hypertensive patients? * Does the intervention increase patients' knowledge about hypertension? * Does the intervention reduce emergency hospital admissions among hypertensive patients? We will compare patients who receive telemedicine-based counseling with patients who receive usual care to see if the intervention improves self-care, medication adherence, knowledge, and reduces emergency admissions.

Participants will:

* Receive 10-15-minute telephone counseling sessions every two weeks for three months (intervention group only) * Receive education on blood pressure monitoring, medication adherence, diet, physical activity, and stress management (intervention group only) * Continue routine hypertension care at the hospital (both groups)
