Clinical Trial Summary

In relation to rapid urbanization, demographic transition and childhood conditions obesity and type 2 diabetes (T2D) is increasing in an alarming rate in Africa. With an increase in the rate of diabetes in Ethiopia, responses to reduce its occurrence and delaying or preventing complications is not adequate. One of these strategies is empowerment of diabetes patients on self-care.

The main objective of this project is to assess effects of phased and intensified DSME on psycho-social, clinical, and behavioral outcomes among adults with T2D in Ethiopia.

An interventional two groups study design was employed to determine the desired effect of DSME. The study participants were selected randomly from adult T2D patients attending Jimma University Medical Center (JUMC) chronic illness follow-up clinic. Using the assumption of increasing the proportion of people with controlled blood glucose from 18% to 33% the sample was calculated 120 with participants in the intervention group and 120 in the comparison group.

To reduce risk of contamination, we planned to vary the intervention and the comparison group based on their residence using kebele (the smallest administrative unit) for residents of Jimma town and woreda or district for those outside of Jimma town. Because of the inconvenience to vary days of appointment, where those supposed to come on Monday were coming on Tuesday and those supposed to come on Monday were coming on Tuesday, that created a high risk of mix-up of participants. Because of this reason, though the baseline was collected from February 2016 to May 2016, the intervention was delayed by five months and then started on November.

Face to face group-based DSME has been given to the intervention group from November 2016 to April 2017. Then the participants will be further followed for three months to determine the effect of phased and intensified DSME on the control of BGL as measured by HbA1c.

In order to make it culture-friendly educational materials were prepared with two widely used languages, Amharic and Afan Oromoo. First, the teaching materials were prepared in English then translated to Amharic and Afan Oromoo separately by bilingual experts. Then, different bilingual experts back translated to English. Finally, with these experts, common discussion was made and the final teaching materials were produced. The package of teaching materials includes booklets, fliers, and posters prepared in both languages.

Description:

As incidence and prevalence of non-communicable chronic diseases (NCDs) is increasing, care of individuals with NCDs become challenging, complex and expensive (1). One of the models used for the management of NCDs is the mode developed by Wagner and his colleagues in 1990s. Of the six components of the model self-management support has been identified and customized to diabetic care which helps to assist diabetic patients to overcome attitudinal and motivational barriers, improve their self-management skills and feelings of self-efficacy (2).

The objective of DSME is to support the individual to make informed decision, cope with daily demands of diabetes, make behavioral changes that support their self-care practice, active collaboration with the health care team and improve clinical outcomes, health status, and quality of life (3, 4).

In some of developed countries, it was found that DSME is effective in reducing HbA1c, BGL, BP, BMI, anxiety, need for diabetes medication and risk of complications as well as improve diabetes knowledge, sound activity, diet, self-care practice, quality of life (5-8).

Though very few intervention studies related to DSME are conducted in a very few countries (9-12), the role of culture friendly DSME in Africa is not well understood. In addition, since Africa has a different living style, culture, belief, and probably different risk factors of diabetes as well, the effectiveness of DSME is not well understood and it has not been given a due attention. Similarly, in Ethiopia despite large number of people with diabetes, so far to our knowledge no organized DSME has been developed, tested and implemented.

Therefore, exploring effectiveness of DSME in Ethiopian context is paramount. The findings from this study can be important to help patients living with Diabetes 2 to leave healthier life by reducing/preventing the occurrence of complications. Moreover, it may initiate policy makers, health planners and other relevant stakeholders about importance of diabetes control using self-management education and support. At the same time, self-management is expected to contribute to improve clinical outcome, reduce risk factors, prevent or delay of disabilities and ultimately improve the quality of life for the individuals and their families. This may in turn enables societal members to participate in the country's economic growth and development. The findings of this study will also be used as a baseline for future related studies. The finding of the study can also be used as a starting point for the Ethiopian Federal Ministry of Health (FMoH) and the respective regional health bureaus to develop and implement culturally friendly DSME model. Moreover, it can initiate relevant bodies to design short-term and long-term curriculum for training of relevant front line health care providers, like nurses or community health workers, who will have a central role in the support of clients with diabetes.

Objective The main objective of the project is to assess effects of DSME on behavioral (self-care practice including nutrition and activity, medication adherence and healthcare utilization), clinical (glycemic control as measured by HbA1c, BP, BMI, and WC) and psychosocial (HRQoL, depression, anxiety, self-efficacy and diabetes knowledge,) outcomes among adults with T2D in Ethiopia, and particularly in Jimma zone.

Research questions

1. How do DSME affect dietary choices and exercise among adults with T2D attending JUMC chronic illness follow-up clinic?

2. Do DMSE improve medication adherence and health care utilization by adults with T2D attending JUMC chronic illness follow-up clinic?

3. Do DSME improve the health status of adults with T2D attending JUMC chronic illness follow-up clinic? These research questions will be addressed in separate sub studies. Taking glycemic control as primary outcome, the effectiveness of DSME will be evaluated by an absolute increase of the proportion of people with good glycemic control by 15%.

Design A before and after interventional controlled study design will be employed to explore the effects of DSME among adults with T2D attending JUMC.

Setting The study will be conducted in JUMC, Jimma Ethiopia. Currently 477 T2D patients get follow-up care in the chronic diseases follow up clinic of the hospital. Of these around 330 of them are 18 years and above. So far, to our knowledge there is no formal structured education arrangement for all diabetes patients visiting the clinic.

Study period The project will be completed within four years period from January 2015 through 2018.

Recruitment, participants and sampling Based on physicians' diagnoses recorded and history of medicines they are taking T2D patients were identified. Further, these T2D patients were categorized according to their living residence. Roughly, since the number of patients from kebeles (the smallest administrative unit) of Jimma town and woredas/districts outside of Jimma town is equal, kebele for those from Jimma town and woreda for those from outside of Jimma town were used for patient categorization. Then based on their kebele/woreda block randomization to either the intervention or the comparison group was made. For monitoring participation in the DSME sessions, on recruitment their full address was collected.

Sample size was calculated using Epi info_7.exe. with the assumption that DSME will increase the proportion of diabetic patients with controlled BGL from 18% (13) to 33%. Adding 15% non-response rate the final sample size become 240, where 120 are in the intervention and 120 in the comparison group.

Inclusion criteria Adults 18 years and older with confirmed T2D (as diagnosed by physicians and based on the history of medicines they have been taking) Exclusion criteria Patients with diabetes type 1, gestational diabetes, pregnant women and people with severe cognitive impairment or terminally ill people Intervention Training handbook For a phased and an intensified DSME, an Ethiopian context patient friendly handbook with illustrative pictures has been prepared. To help illiterate/less-literate patients the DSME materials are mainly supported by illustrative pictures with short text explanations. The content includes: basics of diabetes, healthy eating, healthy exercise, medication management, prevention of acute and long-term complications, foot care and psychosocial issues in diabetes.

For contextualization appropriate expertise like physicians, nurses, pharmacists, linguistics and others were consulted. All the DSME materials were translated in to Amharic and Afan Oromoo languages.

Provider The DSME sessions have been given by the PhD student and a clinical nurse who has experience of working with diabetes patients and is fluent in Afan Oromo and Amharic. The nurse was trained for a total of 16 hours before starting the education session.

Duration Participants enrolled in the intervention group sessions of have got DSME every month on their date of appointment for six consecutive months for a total of approximately 9 hours. For convenience all the sessions will be held on the date of their routine follow-up before seen by doctors.

Approach Each of the six sessions was interlinked with take home activities and experience sharing in the subsequent session. The first five sessions was framed with specific areas of discussion, whereas the sixth (last) session will be revision through sharing their experiences over the last five months. After the six sessions were addressed over six months, the intervention group was followed for the next three consecutive months with brief sessions of discussion. The comparison group continued getting the usual care.

The approach of the DSME sessions focused on experience sharing where patients share their experiences of diabetes management, daily life, life-style modification, complication risk reduction, etc. which is supported by education sessions.

Data Collection Tool and Technique At base line data was collected from both intervention and comparison groups. Then, three months after completion of DSME end-line survey will be conducted.

For base line data collection interview of patients, record review, anthropometric measurements, and laboratory tests were used. Before data collection those doing interview, taking anthropometric measurements, and taking blood samples were trained for one day.

Data related to socio-demographic characteristics, food security, diabetes self-care practice, medication adherence, health care utilization, BP, weight, height, WC, BGL, HbA1c, HRQoL, self-efficacy, depression, stress and diabetes knowledge were collected at baseline and follow-up surveys. In addition, at the end of the intervention patients' feeling about the overall DSME sessions will be elicited. Key points from the group discussions have been recorded by the PhD student.

This project is being undertaken in a resource limited facility where laboratory facility is limited, bureaucracy or uncooperativeness of administrative bodies and different members of health care team may happen to use existing laboratory services for the end-line survey.

Pilot All of questionnaires/tools was translated to Amharic and Afan Oromo and then back translated to English. Before the actual intervention and baseline survey a pilot study was conducted on a 5% of the study population to customize the questionnaires to the Ethiopian context. Based on findings from the pilot, appropriate amendments were made.

Analysis Descriptive statistics will be used as required. Chi-square tests will be employed to compare the intervention and comparison groups, in terms of the components of outcomes. Logistic regression will be employed to determine factors affecting the implementation of DSME. Intension to treat analysis will be used for the analysis of the outcome variables.

Regarding qualitative data from each group discussions, key data will be summarized, and analysis of comments or quotes of participants will be labeled for analysis by theme.

Research Ethics Before the commencement of the study, ethical approval letters were secured from REK (Norwegian Regional Committee for Medical and Health Research Ethics) and Jimma University Ethical Review Board. Moreover, at the level of recruitment a written consent was secured from each study participant.

Since the aim of the study is to determine the effect of DSME, the comparison group didn't get education. Nevertheless, like the intervention group their blood glucose have been tested on every visit. Moreover, during base line survey any question that the comparison group members asked have been explained, which will be similar on the end-line survey too.

Blood samples and data that are registered about the patient only be used in accordance with the purpose of the study. On base line blood sample collected for BGL and HbA1c was discarded immediately after the analysis procedure. Similarly on the end-line survey blood samples will be discarded immediately after the test is done. All the data and samples are being processed without name, ID number or other directly recognizable type of personal information. A code number links the specific patient to his/her data and samples through a list of names. Only authorized project personnel have access to the list of names and be able to identify the patient. All data is stored in Services for Sensitive Data (TSD) server of University of Oslo. It will not be possible to identify individual patient in published or presented results from the study. All data will be discarded five years after the end of the project.
