Effectiveness of OHP in Improving Self-efficacy in Patients With Diabetes Mellitus

Study Overview
=================
Brief Summary
-----------------
Addressing the increasing trend in diabetes and mental illness co-morbidities, Malaysia is currently in need of a self- management program that promotes patient empowerment and overall well-being - beyond education. Committing to the self-care behaviours is highly dependent on the individual's self-efficacy. Self-efficacy has been shown to have a direct positive relationship with self-care behaviours, direct negative relationship with psychological distress and depression. Self-efficacy has also been found to hold a mediating effect on the relationship between emotional distress and self-care behaviours. The objective of this study is to assess the effectiveness of a self-management program for patients with diabetes, the Optimal Health Program (OHP) in improving self-efficacy, depression, anxiety, diabetes distress, well-being and self-care. This study is a randomized controlled trial study of patients with diabetes attending the four diabetes health clinics within the Putrajaya District. Eligible patients will be randomly allocated to either treatment as usual (TAU) or OHP and treatment as usual (OHP + TAU). The treatment as usual group (TAU) participants will be invited to participate in the OHP at the end of the study. The participants in the OHP + TAU will attend 5 weekly 1.5 hour sessions and a booster session at 3 months. Following ethics approval, recruitment and training will commence in September, data collection expected to be until April 2020. It is hypothesized that the OHP + TAU group will have higher self-efficacy, well-being and self-care scores and reduced depression, anxiety, diabetes related-distress and HbA1c. This study will contribute towards the gap in the literature in the effectiveness of a self-efficacy enhancing psychosocial self-management program among diabetes patients in Malaysia within a primary care setting.

Detailed Description
-----------------
Background and Significance Diabetes currently affects 1 in 5 adults, with the most affected within the productive age span and an expectation of continual increase in the future. Mirroring the global trend, Malaysia has approximately 2.6 million adults having diabetes mellitus in Malaysia with an up to 31% increase from 2006 to 2011. The complexity of diabetes mellitus itself is associated with not just the physical health but also the patients' emotional well-being and mental health, social, occupational and overall quality of life. The current blooming diabetes population with increasing psychosocial barriers brings about a huge impact on the complexity of diabetes. Psychosocial self-management is central to effective management in diabetes. Nonetheless, committing to the self-care behaviours is highly dependent on the individual's self-efficacy. Self-efficacy is the individual's belief about their capabilities to cope and manage their diabetes. Self-efficacy can be assessed based on the individual's perceived ability - (1) to conduct the specific diabetes self-care activities and (2) to manage their psychosocial issues related to diabetes psychosocial self-efficacy. Self-efficacy has been shown to have a direct positive relationship with self-care behaviours 4, direct negative relationship with psychological distress and depression. Self-efficacy has also been found to hold a mediating effect on the relationship between emotional distress and self-care behaviours. Addressing the increasing trend in diabetes and mental illness comorbidities, Malaysia is currently in need of a self- management program that promotes patient empowerment and overall well-being - beyond education. With limited mental health professionals and resources, there is a greater need to build the capacity of the health care system especially within the primary care setting. A low intensity intervention program that plays a preventative as well as a curative role conducted within the primary care setting would be of great significant. Based on the theory of Self-Efficacy, the Optimal Health Program (OHP) is a self-efficacy enhancing management program that promotes patients to be actively involved in their own healthcare and overall well-being. The aim of OHP is to improve a person's health literacy and overall wellbeing through self-efficacy and understanding their strengths and vulnerabilities. Evidently, OHP has shown to be effective in improving health and social functioning in mental health patients, substance use and psychotic disorders. The OHP has slowly expanded towards managing physical health and chronic illnesses. Due to its holistic approach by addressing multiple areas of an individual's life creates tremendous potential in the management of the complexity of chronic illness. OHP will be the first engagement tool in Malaysia that will allow health care professionals to address the mental health issues and promote overall wellbeing in these chronic ill patients. OHP is a low intensity intervention program that can be delivered by trained facilitators. The delivery of self-management programs has been shown to be equally effective when delivered by diabetes educators, peers, practice staffs as well as specifically trained program facilitators. Through the OHP it is hope that it will provide a low intensity intervention program for early intervention within the primary care setting that can be delivered by a broad range of health care providers. It offers a platform for wide range of health care providers within the primary care to engage in a discussion with patients regarding their well-being through a patient centered collaborative approach. Additionally, in 2015, the 5th edition CPG Management of Diabetes Mellitus Type 2 was issued. The standard of practice especially within the primary health care is greatly guided by the National Clinical Practice Guideline (CPG). The latest CPG puts a greater emphasis in early screening and detection inclusive of mental health issues and patient centered care. With this greater emphasis, it is worthwhile to further examine the effectiveness of the current standard of practice as guided by the latest version of the CPG or whether an add-on psychosocial self-management program to the current practice would yield greater impact. Significance of study Based on the National Health Morbidity Survey 2015, the prevalence for diabetes in Putrajaya was reported to be above the national prevalence and at the top half highest prevalence for diabetes (19.2%) as compared to all the states in Malaysia, Moreover, Putrajaya had the highest prevalence for overweight (37%) and abdominal obesity, obesity I, obesity II as well as obesity III (25.8%). Despite that, Putrajaya was found to have the second highest prevalence for adequate health literacy (16%). Even though the understanding and knowledge on ways to promote and maintain good health was comparably high, prevalence of diabetes and obesity were still at large. This may imply a dissonance between being educated on the illness and the ability to utilize the knowledge to commit to healthy lifestyle changes. Enhancing self-efficacy links this dissonance - that is by improving people's beliefs of their own capabilities to self-manage their diabetes and to produce an impact in their lives. Therefore, this study will contribute towards the gap in the literature in the effectiveness of a self-efficacy enhancing psychosocial self-management program among diabetes patients in Malaysia. The OHP provides an engagement tool that works as a curative and preventative role for primary health care providers. The OHP is a low-intensity, structured, psychosocial program that emphasizes well-being as compared to illness that is suitable to be given within a primary health care setting . Specifically, it will be looking at the effectiveness of OHP and treatment-as-usual (TAU) as compared to TAU alone, in improving self-efficacy in patients with diabetes that are currently attending the health clinics within the Putrajaya district. In addition, it will also examine the effectiveness of OHP in improving anxiety, depression, diabetes-related distress, self-care behaviours and glycemic control.
