Peer Support Intervention Effect on Medication Adherence, Self-care and Knowledge Among Patients With Diabetes: A Randomized Control Trial
Peer Support Intervention Effect on Medication Adherence, Self-care and Knowledge Among Patients With Diabetes: A Randomized Control Trial
The goal of this interventional study is to learn about the effect of a peer support group intervention on adherence, self-care practice, and knowledge among diabetic patients on follow-up care. The main question it aims to answer is:
BACKGROUND Diabetes mellitus (DM) is a chronic metabolic disorder that comes as one of the fastest-growing global health challenges, with the number of affected individuals projected to reach 643 million by 2030 and 783 million by 2045. Sub-Saharan Africa is experiencing a rapid rise in DM prevalence, partly due to urbanization, lifestyle changes, and limited access to preventive and treatment services. In Ethiopia, diabetes contributes substantially to the burden of non-communicable diseases, yet many patients fail to achieve optimal glycemic control.
Peer support is considered a promising, feasible, and culturally appropriate enhancement to diabetes care, enabling participants to assist one another in their ongoing self-management efforts. It is effective in preventing the complications of diabetes and enhancing health outcomes in patients with diabetes. Previous systematic reviews have reported that programs were effective for diabetes outcomes, including glycemic control, knowledge of diabetes, self-management skills, and self-efficacy. A healthy lifestyle, an appropriate diet, and medication adherence among diabetic patients are essential factors in the prevention of diabetes complications as well as maintaining good glycemic control. However, many patients with diabetes fail to manage the disease due to its complex nature. Hence, patients with diabetes need self-management education to assist them in comprehending and dealing with the disease.
Several rigorous reviews have demonstrated that adherence to treatment among patients with chronic diseases in developed countries is about 50%. Considering the scarcity and inequities in access to healthcare services in developing countries, this rate is assumed to be even lower. Poor adherence to diabetes medications is common among African Americans and contributes to these disproportionally worse outcomes. Numerous studies suggested that diabetic peer support programs have positive outcomes on improvement of adherence to medication which is essential for successful diabetes management. For example, Shiyanbola and coworker supported that conduction of an efficacy trial to address medication adherence using a peer-supported tailored intervention is essential. The healthcare effectiveness report from united states (US) point out that inadequate medication adherence is one of the main causes of the differences in glycemic control attainment rates between real-world settings and randomized controlled trials, which emphasizes the need for better provider and patient support programs to improve adherence. Thus, Patient support programs can improve persistence with and/or adherence to medications for the treatment of chronic diseases like diabetes.
Sub-Saharan Africa researches have demonstrated that peer support programs are beneficial and enable participants to modify their lifestyle and adhere to treatment. A study conducted in Uganda showed that improvements in eating habits, diastolic blood pressure, and glycosylated hemoglobin (HbA1c), after peer support program had carried out to diabetic patients and concluded that as it is a workable intervention to enhance diabetes care in health care settings. Additionally, diabetes peer support programs have been demonstrated to enhance patients' health-related behaviors, metabolic management, and quality of life in nations such as South Africa, and Cameroon. After the diabetes peer support program has positively impacted its members in Malawi, the researchers suggested that additional recruitment and ongoing training for peer supporters is necessary to reinforce and update management knowledge and skills. Besides, they concluded that it is a viable strategy for the non-communicable diseases unit within the Ministry of Health. In Ethiopia, fewer than 50% of diabetic individuals obtain proper diabetes care.
Despite the empirical studies showing positive and significant relationships between diabetes peer support and treatment adherence among patients with diabetes, the exact mechanism by which peer support affects patient adherence is not yet completely understood. Further research is needed to address how the differences in types of support, such as functional or emotional support, are linked to outcomes for patients. Specifically, there remains a gap in understanding what constitutes peer support and how to effectively implement it in low-resource environments, like Ethiopia health care settings.
Patient education materials provided by diabetes focused organizations do not increase patient self efficacy or engagement with self management as these documents contain complex medical jargon and provide only general guidelines, not patient-specific instruction. Peer support interventions, where individuals with lived experience of diabetes share advice, encouragement, and practical strategies, offer a potentially powerful extension of these existing support systems. Such programs have demonstrated benefits in enhancing treatment adherence, self-care practices, and disease-related knowledge in various settings. Despite this, there is limited data from Ethiopia on the effect of structured peer support groups among patients receiving care in tertiary hospitals.
This study assesses the effectiveness of a structured peer support group in enhancing medication adherence, self-care behaviors, and diabetes-related knowledge among adult patients attending follow-up at ACSH, a tertiary care facility in northern Ethiopia. The findings aim to inform efforts to integrate peer support into routine diabetes care within similar low-resource environments.
