Development of a health dialogue model for patients with diabetes: A complex intervention in a low-/middle income country

Prevalence and sociodemographic correlates of diabetes among adults in Namibia and South Africa

OBJECTIVE

The aims of this study were to understand the prevalence and sociodemographic characteristics associated with diabetes among adults in Namibia and South Africa.

METHODS

Data from the Demographic and Health Survey for Namibia (2013) and South Africa (2016) were analyzed. The dependent variable, diabetes, was defined using lab values for blood glucose≥ 126 for Namibia, and hemoglobin A1c (HbA1c) ≥ 6.5% for South Africa. Logistic regression was used to identify independent correlates of diabetes for each country. Demographic (age, sex, geographic location, number of children), economic (wealth index, education level), and cultural (religion - Namibia, ethnicity - South Africa) factors were added in blocks to the models.

RESULTS

In Namibia, 4.6% had diabetes based on blood glucose, and 14.6% had diabetes based on HbA1c in South Africa. In Namibia, after adjustment, higher wealth was independently associated with diabetes (OR:1.67; 95% CI: 1.11, 2.50). In South Africa, after adjustment, those who were older (OR: 1.06; 95% CI: 1.04, 1.07), female (OR: 1.25; 95% CI: 1.03, 1.52), lived in a rural area (OR: 1.54; 95% CI: 1.20, 1.96), and Black (OR: 2.27; 95% CI: 1.17, 4.42) or Other (OR: 5.74; 95% CI: 2.50, 13.20) compared to White, had increased odds of diabetes.

CONCLUSIONS

Prevalence of diabetes is high in South Africa and relatively low in Namibia using reliable laboratory diagnostic indices. Strategies to address the rising burden of non-communicable diseases like diabetes are needed in sub-Saharan Africa.

Interactive workshops as a learning and teaching method for primary healthcare nurses

BACKGROUND

Traditionally, learning by and teaching for primary healthcare (PHC) nurses use didactic, teacher-centred approaches. Hence, the feasibility of interactive workshops in non-threatening PHC environments to refresh nurses' knowledge on patient care needs exploring.

AIM

To describe interactive workshops as a learning and teaching method for PHC nurses.

SETTING

Primary healthcare clinics.

METHODS

Systematic literature search followed by an exploratory experimental pre or post-test control group design. Random clinic sampling (n = 26) led to clinic inclusion at the control (n = 5) and experimental (n = 5) sites. Nurses (n = 42) were conveniently selected for the control (n = 21) and experimental (n = 21) groups. Experimental participants (n = 21) attended interactive workshops (n = 5) where various strategies were applied, whilst addressing key diabetes messages. Both groups completed a questionnaire aligned to diabetes messages pre- and post-workshop. Additionally, a Likert scale questionnaire was posed to the experimental group post-workshop. Data was analysed statistically and presented as descriptive statistics, frequencies and percentages.

RESULTS

Articles reviewed (n = 20) identified types of interactive activities, role players, learning content covered, feasibility and duration of the interactive workshops. Pre or post-testing results of the workshops participants indicate improved knowledge related to peripheral sensation (0.03) and (< 0.01). Results from the questionnaire revealed participants' satisfaction with the interactive workshops.

CONCLUSION

Interactive workshops as a learning and teaching method could lead to change in knowledge, and participant satisfaction. However, using a combination of interactive workshops and other teaching modalities may enhance learning and teaching further.

CONTRIBUTION

Interactive workshops are a feasible instructional method during refresher courses for healthcare providers.

Self-management in face-to-face peer support for adults with type 2 diabetes living in low- or middle-income countries: a systematic review

Background

Peer support has been recognised as a promising strategy to improve self-management in patients living with chronic conditions, such as Type 2 diabetes (T2D). The purpose of the review was to synthesise the best available evidence on face-to-face peer support models for adults with T2D in low and middle-income countries (LMICs).

Methods

We searched Medline, Cumulative Index to Nursing and Allied Health, Literature Academic Search Ultimate, PsycINFO, CAB Abstracts, Health Source: Nursing/Academic Edition, SPORTDiscus, Africa-Wide Information, MasterFILE Premier, SocINDEX, ERIC, PsycARTICLES, Open Dissertations, Communication & Mass Media Complete, Health Source-Consumer Edition and Google Scholar for the period January 2000 to December 2017. Reference list checking and contact with authors were additional sources of data. Screening of papers, critical appraisal and data extraction were carried out independently by at least two reviewers.

Results

From 3092 abstracts retrieved from database searches, data was extracted from 12 papers. There was no consistency in design, setting, outcomes or measurement instruments amongst the papers. The papers were associated with improvements in various clinical and behavioural outcomes. Diabetic patients and community health workers (CHWs) were identified as two common face-to-face peer support models. The recruitment and selection of diabetic patients as peer supporters focused on patients from the community, with good glycaemic control and/or leadership skills, who were recommended by healthcare professionals. Recruitment of CHWs as peer supporters was done from an existing infrastructure of CHWs in the community and, thus, selection criteria were poorly described. The training of peer supporters featured as an important component, highlighting who provided training and the duration and content covered in training. Motivational interviewing was the most common theory basis of training used in the peer support interventions. Face-to-face, group and/or individual-based peer support was often supplemented by other peer support methods. The supervision of peer supporters was generally poorly described.

Conclusions

The comprehensive synthesis of the best available evidence has led to new insights regarding face-to-face peer support as a self-management strategy for patients with T2D in LMICs. Face-to-face peer support may be implemented in innovative ways to improve the quality of life of patients with T2D.

Barriers for User Acceptance of Mobile Health Applications for Diabetic Patients: Applying the UTAUT Model

The literature illustrates that technology will widen health disparity if its use is restricted to patients who are already motivated and demonstrate good self-management behaviours. Additionally, despite the availability of free mobile health (m-health) applications for diabetes self-management, usage is low. There are also limited studies of m-health acceptance in South Africa. This research is delineated to the Western Cape, South Africa. The populace suffers from increasing numbers of diabetic patients. Segments of the population also suffer from technological forms of exclusion, such as limited internet access. Therefore, the objective of this study was to identify challenges for user acceptance that discourages the use of m-health applications. This study analysed 130 semi-structured interviews, using thematic content analysis. Respondents were predominantly female with type 2 diabetes, older than 50, residing in the Western Cape. It used key constructs from the Unified Theory of Acceptance and Use of Technology (UTAUT) model. The results confirmed that all four UTAUT constructs; performance expectancy (“the degree to which an individual believes that using the system will help him or her to attain gains in performance”), effort expectancy (“the degree of ease associated with the use of the system”, social influence (“the degree to which an individual perceives that important others believe he or she should use the new system”) and facilitating conditions (“the degree to which an individual believes that an organisational and technical infrastructure exists to support the use of the system”), explains the challenges for m-health acceptance in low socio-economic areas. Factors such as technology anxiety, resistance to change and a lack of trust in the use of devices for self-management need to be considered when implementing future interventions.

Perceptions of patients regarding diabetes-related health communication strategies in the Free State, South Africa

BACKGROUND

This study researched the perceptions of patients diagnosed with diabetes concerning diabetes-related health communication strategies in the Free State province in South Africa. The prolongation and quality of life of patients diagnosed with diabetes are affected by lifestyle choices. An enabler of risk reduction is health communication which informs, influences and motivates individuals to adopted health-focused lifestyles.

AIM

This study sought to describe the perceptions of patients regarding diabetes-related health communication strategies in the Free State, South Africa.

SETTING

This study was carried out in primary health care centres and community health care centres within the Free State province in South Africa.

METHODS

A qualitative, descriptive and exploratory research design was used in this study. Thirty-four patients diagnosed with type two diabetes for at least a year were purposively included in this study. Semi-structured interviews in Afrikaans, English, Sotho and Xhosa were conducted. Data analysis was through inductive reasoning and thematic analysis.

RESULTS

The majority of the respondents were older women having been diagnosed with diabetes for more than 5 years, with at least primary school education and of diverse South African ethnicities. The main prompting questions operationalised the term 'perception', probing their feelings, experiences and knowledge of health-related communication strategies as presented by a variety of information sources. After recording interviews, data were analysed according to themes, categories and sub-categories.

CONCLUSIONS

The study highlights factors that encourage patients to seek help and foster attitudes of compliance. Practical problems regarding the management of diabetes are underlined. The role of family, as well as the patient-caregiver relationship, in the acceptance and management of the disease is revealed. Societal perception of male symptomology is shown. The study offers information to stakeholders and health care workers for continued successful management of diabetes in communities.
