Telehealth Educational Intervention for Adults With Type 2 Diabetes in Oman

The goal of this clinical trial is to find out whether adding a nurse-led telehealth educational program to usual diabetes care can improve blood sugar control, medication-related behaviors, and quality of life in adults with type 2 diabetes in Oman. The main question this study aims to answer is whether adults who receive the telehealth educational program, in addition to their usual diabetes care, have better blood sugar control after 6 months than adults who receive usual diabetes care alone. Blood sugar control will be assessed using hemoglobin A1c (HbA1c), a blood test that reflects average blood sugar levels over the previous few months. The study will also examine whether the telehealth program improves participants' attitudes and behaviors related to taking their diabetes medicines and their diabetes-related quality of life. Among participants receiving the telehealth intervention, the study will also assess how easy, useful, reliable, and satisfactory they find the telehealth service. Approximately 160 Omani adults with type 2 diabetes will take part in the study. Participants will be randomly assigned to one of two groups. One group will continue usual diabetes care and will also receive an individual telehealth education session once a week for 24 weeks. Each session will last about 20 to 30 minutes and will be provided by a trained nurse using an approved secure telehealth platform. The sessions will cover topics such as diabetes and HbA1c, safe use of medicines, strategies for remembering medicines, healthy eating, physical activity, blood glucose monitoring, recognition of low and high blood sugar, prevention of diabetes complications, stress and sleep, and communication with healthcare professionals. The other group will continue to receive usual diabetes care without the additional study telehealth education program. No established diabetes care will be withheld from either group, and the telehealth education will not replace routine medical care
