Introduction

Globally over 14 million people die each year from non-communicable diseases such as diabetes mellitus between the ages of 30 and 70, of which 85 per cent are in developing countries [1]. Ethiopia is among the top five countries with the highest number of people affected by diabetes mellitus in Sub Saharan Africa [2]. As a result hospital admissions for diabetes management has been rising in recent years [3, 4].

Effective management of diabetes requires strong and consistent cooperation of the patient [5]. Often the complications associated with diabetes management are highly attributable to the failure to comply with self-care recommendations [6]. The poor self-discipline, and lack of support from family members and/or physicians, poverty and lack of access to health facility are some of the major for failure to comply [7].

There are well recognized and specific self-care components to prevent and/or delay complications and possibility of early death associated with diabetes. The components are self-monitoring of blood glucose level, diet control, optimum physical exercise, adherence to medication/s and proper foot care [8]. Various strategies were adopted in different countries to help people with diabetes improve their self-care practices depending on the context [9]. Implementation of a comprehensive patient education program was reported to have enhanced diabetes self-care practices [10]. Improved social support for patients with diabetes has facilitated diabetes self-care and achieve improved glycemic control [11]. Task shifting is another approach successfully implemented to improve self-care in places where doctors have heavy work load; either nurses or other health professionals were specifically trained to provide proper information to the patient instead of the busy doctor [12]. Understanding patients self-care cultural and value systems is another important factor to designing a responsive program that can influence their diet and exercise choices, trend of blood glucose monitoring, and compliance with prescribed medication regimens [9]. While the burden of diabetes is increasing in Ethiopia, studies conducted to understand self-care practices are very limited. Thus the aim of this study was to describe the diabetes self-care practices and identify facilitators and barriers to the practice among type II diabetes patients attending follow-up in public hospitals.

Methods

The study was conducted in Addis Ababa, the capital city of Ethiopia. There were five public hospitals that ran a special diabetes follow up clinics at the time of the study where patients are appointed every four to six months to see their doctor and receive services in outpatient departments. The clinics provide diabetes education on self-care practices and on proper self-injection techniques. We selected Menelik II and Zewditu memorial hospitals for this study. These two hospitals have been running a separate diabetes follow up clinics for more than three decades. In Ethiopia all public hospitals provide consultation and anti-diabetes medications free of charge. However additional diagnostic treatment services may not necessarily be free unless the patient has a ‘certificate of poverty’ from local administration.

The study participants were patients with type II diabetes that came to follow up clinics between November 2013 and February 2014. The inclusion criteria were having been diagnosed with type II diabetes for at least five years and being between the ages of 35 and 65 years. Patients who were not in a good physical/mental condition during the study time were excluded. As the aim of the study was to describe the day to day self-care practices of patients with diabetes, newly diagnosed patients were not included in the study.

A purposive sampling procedure was used to recruit patients for the study based on their age, sex, educational level, income level, duration of diagnosis/follow up and patient’s personal behaviors. This was done to be able to see the different forms of self-care practices from different perspectives. The doctors and nurses working in the follow up clinics helped in identifying patients that fulfil the inclusion criteria of the study. We tried to include patients believed to be interactive, open minded and those who were willing to participate in the study. Each person identified as potential respondent was then individually asked for consent after being informed about the purpose and the required procedures.

The semi-structured interview guide used for data collection was developed by reviewing relevant literatures. In addition, participants were encouraged to speak up their mind in case they had anything further to tell related to the topic. A pilot was conducted in another public hospital to assess the acceptability and ease of understanding the interview process. Then interview guide was revisited to make the necessary changes and modifications before conducting the actual interviews included in the analysis.

All interviews were conducted by the first author in a private space within the hospital compound. The interviews were conducted in Amharic language, which is the national language of Ethiopia. All interviews were tape recorded with verbal consent obtained from the study participants. In addition relevant notes were taken during the interview to document key issues and observations. Interviews took approximately 45–60 minutes. Interviews were conducted until the point of relative saturation with regard to the issues being discussed.

All interviews were transcribed verbatim in Amharic and then translated into English for data analysis. The translated content was coded manually and entered into a computer software (open-code) used for qualitative data sorting. Codes were given and grouped into categories that were predefined based on the objective of the study. The field notes were included in the memos section of the software. Coding started by a thorough reading of each interview material, followed by line-by-line flagging of each of the interviews. A coding procedure was established jointly by the co-authors.

A thematic analysis approach was used to categorize the codes thorough several iterations. The thematic areas were diet, physical exercise, medication adherence, self- monitoring of blood glucose and foot care. Patients were identified and labeled as “Negligent”, “Confused” and “Endeavour to be compliant” based on their personal coping methods with respect to their self-care practices that emerged during the analysis process.

Ethical clearance for the study was obtained from Institutional Review Board of Addis Continental Institute of Public Health and permission to conduct the study was granted by the Addis Ababa city administration Health Bureau. Interviews were conducted after participants provided verbal informed consent. The interviews were conducted in manners that assured privacy for the respondents. Access to raw data was restricted only to the study investigators.

Results

A total of thirteen in-depth interviews were conducted with type II diabetes patients. All participants have had diabetes for at least five years. Seven of the participants were female. All respondents were between the age of 35and 65, and nine of them were married. With regard to their educational back ground, one has attended college, six had elementary to high school education, and three could not read and write. Participants were from various religious and ethnic groups. None of the patients invited for the study refused to participate in the study.

Participants experiences of the self-care practices

We observed that study participants behaved in different ways in coping with their illness and diabetes self-care. We categorized them into three different groups based on their utterances as: ‘Negligent’, ‘Confused’ and ‘Endeavour to be compliant’. This grouping helps to see their relative level of self-care in relation to their illness coping strategies, as well as their attitude towards self-care (Table 1).

Discussion

Overall, a comprehensive self-care practice among diabetes patients was uncommon. Most of the respondents entirely depended on their medications to manage their illnesses and tend to undermine the importance of the other elements of self-care either due to lack of resource/poverty, lack of awareness, lack of support or negligence [5].

The irregularity of blood sugar monitoring was the main shortcoming of diabetes control in this study. This is a precursor to the development of long term diabetes complications of diabetes. As reported elsewhere in sub Saharan Africa and in Ethiopia, irregular blood sugar measurement was related with the lack of personal glucometers or lack of easy access to health facilities and laboratories [8]. Long intervals between clinic appointments was also reported as one of the reasons for taking the responsibility of self-adjusting medication dosages by patients with diabetes. Provision of a comprehensive education program and task shifting from physicians to nurses or to a person specifically trained to perform a limited task such as delivery of diabetes education was found to be helpful improving patients care in busy diabetes clinics in Sub-Saharan African countries [13].

Food habits in the family and personal food preferences were among the serious challenges which made dietary adjustment difficult for people with diabetes. Participation in social gatherings and food related socio-cultural norms could pose serious impediments to effective diabetic control in Sub-Saharan Africa [9, 12]. In addition shortage of cash to purchase food items appropriate for persons with diabetes, craving for cultural/traditional food and limited availability of variety of food items in the local market are barriers to dietary self-care practices as seen from this as well as other studies in similar settings [12].

Physical exercise, regardless of weight or body mass index, is critical to effectively control blood sugar level and in reducing persistent hyperglycemia [2, 12]. Lack of appropriate information and lack of motivation to engage in a regular physical exercise are common short comings of diabetes self-care practices [14]. Although most people in Africa walk on foot every day, illness and old age can eventually significantly reduce patients’ ability to walk as usual [12]. For aged and ill individuals going to a gym regularly may not be feasible due to either cost or physical distance. Thus, appropriate guidance needs to be given for the kind of exercise that can be done at home [15].

Injection site pain and abscess are common side effects that impede strict medication adherence among people with diabetes [16]. However, adherence to anti-diabetes medication was better of all self-care practices [17]. This could be due to either over reliance on medication or its free availability, or the ease to practice it compared to the other components which require more commitment [18].

Foot care was the least practiced diabetes self-care in our setting. This could be due to lack of proper understanding of its importance or the consequences by persons with diabetes [18]. In Sub-Saharan Africa foot wound gets often complicated resulting in severe infection/sepsis gangrene [2]. A proper diabetes education has shown a promising improvement on foot self-care practice [19].

Studies show that persons with diabetes experience disproportionately high rates of social and emotional difficulties compared to the general population. Negative emotions such as frustration and feeling of helplessness contributed to poor self-care practices including poor blood sugar monitoring [7, 20].

We grouped the behavior of persons with diabetes in to three based on their utterances: The ‘Endeavor to be compliant’ reach out to other people and diabetes association to discuss their condition and could build their motivation for positive self-care practices [21].

Those grouped under ‘confused’ were mostly the ones who seemed to be lacking information, although they keenly wanted it. Even if some knew about diabetes association, they were not acquainted with any benefit that they could individually get from them. This lack of information is commonly observed in both developed and developing countries [11]. These patients are tangled in fear and confusion that their self-care practices are not sufficient to assist their diabetes control. This group are likely to be very frightened of the perceived complications [18].

The third group, ‘Negligent’, appeared to resist self-care recommendations; consequently their self-care practice is very limited and uncommitted. These patients ignore their condition (diabetes), and as a result refuse to discuss about it either with peers or join diabetes association. Glycemic control in such patients tend to be poor and their chance of developing complications early is high [18].

In conclusion, Diabetes self-care is generally poor mainly due to insufficient guidance and support provided to persons with diabetes. Greater attention needs to be given to improve patient education and support in diabetes clinics to ensure better self-care practices and avoid early development of complications.
