The social diagnostics of stroke-like symptoms: healers, doctors and prophets in Agincourt, Limpopo Province, South Africa

Transitioning to a life with disability in rural South Africa: A qualitative study

Background

Adjustment to the onset of disability has complex reverberations relating to both socially engendered disadvantage and the realities of functional limitation. Pre-existing ways of understanding disability can meaningfully shape this experience.

Objective

This study aimed to provide an exploratory understanding of the experience of becoming disabled in a low-income, under-served, rural South African community. In particular, it was interested in how people with disabilities constructed their struggle within the conceptual split between disadvantage caused by ‘malfunctioning’ bodies (a ‘medical model’ view) and that caused by social organisation (a ‘social model’ view).

Methods

Seven people between the ages of 39 and 47 who had acquired a physical disability within the last 4 years were recruited in a rural area of Limpopo province, South Africa. Semi-structured face-to-face interviews were conducted, and the resulting data were thematically analysed. The authors were positioned as both ‘insiders’ and ‘outsiders’ to the participants and sought to use this orientation to best understand and stay faithful to participants’ views while simultaneously applying participant’s experiences to conceptual knowledge in disability studies.

Results

Four themes emerged: (1) emotional impact of onset of disability, (2) being introduced to disablist prejudice, (3) being required to take on a ‘disabled’ identity and (4) socio-economic implications of becoming disabled. The findings reflected a complex set of adverse experiences in the lives of the participants, spanning disadvantages based on embodied, cultural, relational and environmental factors, which were superimposed on existing, generalised poverty in their local communities. Participants made sense of their predicament in multiple, evolving ways.

Conclusion

This study contributes to the understanding of the complex predicaments, and sense-making, of persons who have acquired a disability in a rural, impoverished Global South environment.

Explanatory models of stroke in Ghana: perspectives of stroke survivors and their caregivers

Objective: This study examines explanatory models (EMs) of stroke and its complications among people living with stroke, and their caregivers, in two urban poor communities in Accra (Ga Mashie) and Korle Bu Teaching Hospital (KBTH), Accra.Methods: Twenty-two stroke survivors and 29 caregivers were recruited from 2 urban poor communities in Accra and KBTH. Qualitative data were obtained using semi-structured interviews that lasted between 45 minutes and 2 hours. The interviews were audiotaped, transcribed and analysed thematically, informed by the concept of EMs of illness.Results: Participants referred to stroke as a sudden event and they expressed different emotional responses after the stroke onset. Stroke survivors and their caregivers attributed stroke with poor lifestyle practices, high blood pressure, unhealthy diet and dietary practices, supernatural causes, stress, family history, other chronic diseases, and delay in treatment of symptoms. While the stroke survivors associated stroke complications with physical disability and stigmatisation, the caregivers associated these with physical disability, behavioural and psychological changes, cognitive disability and death. These associations were mostly influenced by the biomedical model of stroke.Conclusion: The biomedical model of stroke is important for developing interventions that will be accepted by the stroke survivors and the caregivers. Nevertheless, sociocultural explanations of stroke need to be taken into consideration during delivery of medical information to the participants. This study proposes an integrated biopsychosociocultural approach for stroke intervention among the study participants.

'What the herbal medicine can do for me in a week, the orthodox does in a year': Perceived efficacy of local alternative therapies influences medication adherence in patients with atherosclerotic cardiovascular disease

Background

There is strong evidence that anti‐platelet therapy, ACE inhibitors, beta‐blockers and statins are cost‐effective in reducing subsequent cardiovascular disease (CVD) events in patients with atherosclerotic cardiovascular disease (ACVD). In some settings, only a low proportion of people have access to these medications, and even lower adhere to them. The current study explored and presents data on the causes of poor adherence to orthodox medication and motivations for alternative therapies in patients with established atherosclerotic cardiovascular disease (ACVD).

Methods

The study was conducted among city‐dwelling adults with ACVD in Accra – Ghana's capital city. Eighteen interviews were conducted with patients with established ACVD. A follow‐up focus group discussion was conducted with some of them. The protocol was approved by two ethics review committees based in Ghana and in the United Kingdom. All participants were interviewed after informed consent. Analysis was done with the Nvivo qualitative data analysis software.

Results

We identified motivations for use of alternatives to orthodox therapies. These cover the five dimensions of adherence: social and economic, health‐care system, condition‐related, therapy‐related, and patient‐related dimensions. Perceived inability of an orthodox medication to provide immediate benefit is an important motivator for use of alternative forms of medication.

Conclusions

A multiplicity of factors precipitate non‐adherence to orthodox therapies. Perceived efficacy and easy access to local alternative therapies such as herbal and faith‐based therapies are important motivators.

Clinical Characteristics, Treatment Outcomes, and its Predictors Among Hospitalized Stroke Patients in Ambo University Referral Hospital, West Ethiopia: A Retrospective Hospital-Based Study

Background

Stroke is becoming a leading cause of death and adult disability in the developing world.

Objective

The objective of the study was to assess the clinical characteristics, treatment outcomes, and its predictors among stroke patients admitted to Ambo University Referral Hospital (AURH), West Ethiopia.

Methods

All 111 stroke patients hospitalized from April 2016 to May 2019 were included using a hospital-based retrospective study. Socio-demographic profile, past medication history, clinical presentation, drugs prescribed for comorbid condition and stroke treatment, and outcomes data were collected using data abstraction formats and results were summarized using both descriptive and inferential statistics.

Key Findings

According to WHO clinical criteria, 89 (80.2%) were diagnosed with ischemic stroke, and 20 (18.0%) were diagnosed with hemorrhagic stroke. The majority of the patients 94 (84.7%) had at least one antecedent risk factor in which hypertension accounted for 44.1%. More than half, 69 (62.2%), of hospitalized stroke patients had good treatment outcomes while 42 (37.8%) had a poor outcome. The overall case-fatality rate was 18 (16.2%), 12 (13.5%) from ischemic stroke, and 6 (30.0%) from hemorrhagic stroke. Acetyl salicylic acid (ASA) with atorvastatin/simvastatin, 67 (73.5%) in ischemic stroke and 12 (60.0%) in hemorrhagic stroke, was the most frequent medications prescribed for stroke during admission while it was frequently prescribed for 48 (53.6%) of ischemic stroke and 10 (50.0%) of the hemorrhagic stroke on discharge. Overall, ceftriaxone + metronidazole 32 (28.8%) was frequently prescribed concomitant medications during admission. The major predictors identified for poor stroke outcomes were substance abuse (AOR=2.839, P=0.024) and have had not received any medication for stroke treatment during admission (AOR=12.503, P≤0.001).

Conclusion

A significant number of the admitted stroke patients had poor treatment outcome in which the case-fatality rate was relatively high. Substance abuse and having not received medication for stroke were the significant predictors for poor treatment outcome. Hence, a well-established stroke unit setup at AURH is required for accurate diagnosis and management of stroke to overcome stroke-related mortality and/or poor treatment outcome.

Stroke Happens Suddenly so It Cannot Be Prevented: A Qualitative Study to Understand Knowledge, Attitudes, and Practices about Stroke in Rural Gadchiroli, Maharashtra, India

Background  Strokes have emerged as one of the leading causes of deaths in rural India but people often remain uninformed about it. This study sought to understand knowledge, attitudes, and healthcare-seeking practices about strokes in rural Gadchiroli, India.

Methods  A total of 12 focus group discussions were conducted with 34 female and 43 male participants from six villages. Responses were audio recorded, transcribed, coded, and analyzed using inductive method of qualitative data analysis.

Results  Respondents correctly recognized many symptoms of stroke and were aware of the sudden onset of symptoms. They were unaware of transient ischemic attacks. After stroke, healthcare was sought from private physicians, and physicians in the government run district hospital, or traditional herbal providers depending upon the accessibility, affordability, and perceived effectiveness of the therapy. Most of the respondents thought that stroke is a serious disease associated with disability as well as death and its occurrence in the community is increasing. However, only a few participants could correctly state how stroke occurs and its risk factors. Furthermore, many participants thought that stroke cannot be prevented as it occurs suddenly without any warning.

Conclusion  Rural people in Gadchiroli were aware of symptoms of stroke but awareness about the etiology and the risk factors was low. Suddenness of symptoms was perceived as a key barrier to taking any preventive action. Understanding such perceptions and addressing them can help improve counseling of patients by physicians and effectiveness of behavioral change communication to prevent stroke in rural areas.

Understandings of stroke in rural Malaysia: ethnographic insights

BACKGROUND

Stroke is a public health concern in Malaysia but local beliefs and lay understandings of stroke have not been examined before. Explanatory models provide a way for people to make sense of their illness and influence health seeking behaviors, in a locally relevant way.

METHODS

Drawing on ethnographic research from rural Malaysia, this descriptive article explores ethnic Malaysian-Chinese stroke survivors' lay understandings of stroke. Eighteen community-dwelling stroke survivors aged 50-83 took part in the study.

RESULTS

Causation of stroke was derived from cultural, biomedical and social sources. Participants also drew simultaneously from both biomedical and traditional explanations of stroke to develop their own understanding of etiology. Similarities with biomedical causation and other studies from different cultures were found. Participants' typically focused on the more immediate effects of stroke and often do not attribute causation and association with their comorbid conditions which are also risk factors of stroke.

CONCLUSION

Lack of knowledge about stroke and its symptoms was evident in participants' account. Findings emphasize the importance of knowledge based health interventions, especially in health education strategies for stroke survivors to reduce delays to diagnosis and potentially improve health outcomes post-stroke. Implications for rehabilitation Stroke survivors often form explanatory models of stroke that draw from both biomedical and traditional explanations of stroke. Understanding how people derive lay understandings of stroke can contribute towards developing the goals and activities that facilitate recovery and rehabilitation in similar settings. Health practitioners in the community should strengthen communication regarding the identification, etiology and risk factors of stroke with stroke survivors and their carers to improve compliance to medication, exercise and diet for better recovery. Sustained health education which is culturally relevant is recommended. Communication should also include non-physical impact of stroke (such as cognitive deficits and emotional difficulties) as the stroke survivors were unlikely to relate such symptoms to stroke.

Understanding the cultural meanings of stroke in the Ghanaian setting: A qualitative study exploring the perspectives of local community residents

Background: Stroke has undergone different medical constructions over the years. While the medical profession posits that disease is a biological condition, universal and unchanging, social constructionists perceive illness as the social meaning of the biological condition. Even though the medical notion of stroke is monolithic and sometimes contradicts the representations by local community residents, little attention has been paid to understanding the cultural meanings of stroke. This study explores the cultural meanings of stroke in five different cultural settings across Ghana. Methods: 30 focus group discussions (FGDs) were conducted with local community members in five communities (Ga Mashie, Tafo, Gyegyeano, Chanshegu and Agorve) located in five regions in Ghana. The FGDs were conducted in Ga, Twi, Fante, Ewe and Dagbani, and were transcribed verbatim into English. The transcripts were analysed thematically. Results: The local words used for stroke in all the five cultural settings focused on physical disability associated with stroke after its onset, and this formed the dominant source of fear about the condition. Participants mentioned that spiritual and left-side stroke have the most debilitating impact on the sufferer. Although there was a general consensus that anyone can be at risk of stroke, there was a gender dynamics in the explanation of risk relativity. Participants believed that stroke can be cured through early detection and treatment, use of herbal medicines, and availability of financial resources. Compared to other disabling conditions, the community residents perceived stroke to be more severe due to the multifaceted disabilities associated with the condition. Conclusions: This study showed that the social meanings of stroke in the five communities are multifaceted, and reflected co-existence of biomedical and cultural frameworks.  The findings showed the need to pay good attention to the sociocultural context when developing interventions strategies on stroke prevention and control in Ghana.

Healthcare utilization for common infectious disease syndromes in Soweto and Klerksdorp, South Africa

Introduction

Understanding healthcare utilization helps characterize access to healthcare, identify barriers and improve surveillance data interpretation. We describe healthcare-seeking behaviors for common infectious syndromes and identify reasons for seeking care.

Methods

We conducted a cross-sectional survey among residents in Soweto and Klerksdorp, South Africa. Households were interviewed about demographic characteristics; recent self-reported episodes of pneumonia, influenza-like illness (ILI), chronic febrile respiratory illness and meningitis in individuals of all ages; recent diarrhea in children aged < 5 years; and consultation with healthcare facilities and providers.

Results

From July-October 2012, we interviewed 1,442 households in Klerksdorp and 973 households in Soweto. Public clinics were consulted most frequently for pneumonia, ILI and diarrhea in a child <5 years old at both sites; public hospitals were most frequently consulted for chronic respiratory and meningitis syndromes. Of all illness episodes reported, there were 110 (35%) in Klerksdorp and 127 (32%) in Soweto for which the person did not seek care with a licensed medical provider. Pharmacies were often consulted by individuals with pneumonia (Klerksdorp: 17, 16%; Soweto: 38, 22%) or ILI (Klerksdorp: 35, 24%; 44, 28%). Patients who did not seek care with a licensed provider reported insufficient time (Klerksdorp: 7%; Soweto, 20%) and lack of medications at the facility (Klerksdorp: 4%; Soweto: 8%) as barriers.

Conclusion

Public government healthcare facilities are commonly consulted for infectious syndromes and pharmacies are frequently consulted particularly for respiratory diseases. Improving medication availability at healthcare facilities and streamlining healthcare delivery may improve access of licensed providers for serious illnesses.

Prospective assessment of patients with stroke in Tikur Anbessa Specialised Hospital, Addis Ababa, Ethiopia

Introduction

The burden of stroke is increasing in many low- and middle-income countries. In Ethiopia, stroke has become a major cause of morbidity, long-term disability, and mortality. Time from stroke onset to hospital presentation is a critical factor in acute stroke care. This study aimed to describe risk factors for stroke and clinical presentation of patients presenting to the emergency centre with stroke.

Methods

We conducted a cross sectional study conducted from August 2015 to January 2016 in an urban tertiary care centre in Addis Ababa, Ethiopia. Descriptive statistics and multivariable logistic regression models were used to evaluate associations between stroke types and stroke risk factors, and delayed presentation and clinical indicators. P-values less than .05 were considered statistically significant.

Results

A total of 104 patients were included. The mean age was 53 years, and 56% were male. Only 30% of patients arrived using an ambulance service. The most common presenting symptoms were altered mental status (48%), hemiparesis (47%), facial palsy (45%), hemiplegia (29%), and aphasia (25%). Hypertension was the most common risk factor (49%), followed by cardiovascular disease (20.2%) and diabetes mellitus (11%). The majority of strokes were haemorrhagic in aetiology (56%). The median arrival time to the emergency centre was 24 h after symptoms onset; only 15% presented within three hours. Patients with hypertension, or presented with loss of consciousness were significantly more likely to have haemorrhagic stroke (p < .001 and p = .01 respectively). The only risk factor robustly associated with ischaemic stroke was cardiac illness (odds ratio 3.99, p = .01).

Discussion

Our study identified hypertension to be the most common risk factor for stroke. The predominant aetiology type in this cohort is haemorrhagic stroke. Lastly, the median arrival time to an emergency centre was 24 h after symptom onset.

Quick and dirty? A systematic review of the use of rapid ethnographies in healthcare organisation and delivery

BACKGROUND

The ability to capture the complexities of healthcare practices and the quick turnaround of findings make rapid ethnographies appealing to the healthcare sector, where changing organisational climates and priorities require actionable findings at strategic time points. Despite methodological advancement, there continue to be challenges in the implementation of rapid ethnographies concerning sampling, the interpretation of findings and management of field research. The purpose of this review was to explore the benefits and challenges of using rapid ethnographies to inform healthcare organisation and delivery and identify areas that require improvement.

METHODS

This was a systematic review of the literature using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We used the Mixed Methods Appraisal Tool to assess the quality of the articles. We developed the search strategy using the Population, Intervention, Comparison, Outcomes, Settingframework and searched for peer-reviewed articles in MEDLINE, CINAHL PLUS, Web of Science and ProQuest Central. We included articles that reported findings from rapid ethnographies in healthcare contexts or addressing issues related to health service use.

RESULTS

26 articles were included in the review. We found an increase in the use of rapid ethnographies in the last 2‰years. We found variability in terminology and developed a typology to clarify conceptual differences. The studies generated findings that could be used to inform policy and practice. The main limitations of the studies were: the poor quality of reporting of study designs, mainly data analysis methods, and lack of reflexivity.

CONCLUSIONS

Rapid ethnographies have the potential to generate findings that can inform changes in healthcare practices in a timely manner, but greater attention needs to be paid to the reflexive interpretation of findings and the description of research methods.

Mixed methods inquiry into traditional healers' treatment of mental, neurological and substance abuse disorders in rural South Africa

BACKGROUND

Traditional healers are acceptable and highly accessible health practitioners throughout sub-Saharan Africa. Patients in South Africa often seek concurrent traditional and allopathic treatment leading to medical pluralism.

METHODS & FINDINGS

We studied the cause of five traditional illnesses known locally as "Mavabyi ya nhloko" (sickness of the head), by conducting 27 in-depth interviews and 133 surveys with a randomly selected sample of traditional healers living and working in rural, northeastern South Africa. These interviews were carried out to identify treatment practices of mental, neurological, and substance abuse (MNS) disorders. Participating healers were primarily female (77%), older in age (median: 58.0 years; interquartile range [IQR]: 50-67), had very little formal education (median: 3.7 years; IQR: 3.2-4.2), and had practiced traditional medicine for many years (median: 17 years; IQR: 9.5-30). Healers reported having the ability to successfully treat: seizure disorders (47%), patients who have lost touch with reality (47%), paralysis on one side of the body (59%), and substance abuse (21%). Female healers reported a lower odds of treating seizure disorders (Odds Ratio (OR):0.47), patients who had lost touch with reality (OR:0.26; p-value<0.05), paralysis of one side of the body (OR:0.36), and substance abuse (OR:0.36) versus males. Each additional year of education received was found to be associated with lower odds, ranging from 0.13-0.27, of treating these symptoms. Each additional patient seen by healers in the past week was associated with roughly 1.10 higher odds of treating seizure disorders, patients who have lost touch with reality, paralysis of one side of the body, and substance abuse. Healers charged a median of 500 South African Rand (~US$35) to treat substance abuse, 1000 Rand (~US$70) for seizure disorders or paralysis of one side of the body, and 1500 Rand (~US$105) for patients who have lost touch with reality.

CONCLUSIONS

While not all healers elect to treat MNS disorders, many continue to do so, delaying allopathic health services to acutely ill patients.

Factors associated with hospital arrival time after the onset of stroke symptoms: A cross-sectional study at two teaching hospitals in Harare, Zimbabwe

Background

Late presentation to hospital after onset of stroke affects management and outcomes of the patients. This study aimed to determine the factors associated with time taken to present to hospital after the onset of acute stroke symptoms.

Methods

A descriptive cross sectional study was conducted at two teaching hospitals in Zimbabwe. Participants included patients admitted with stroke and their relatives. A self-administered questionnaire was used to collect information on history of stroke occurrence and time taken to present to hospital. Data was analysed for means, frequencies, percentages and Odds ratios.

Results

Less than half (33%) of the participants were able to recognize symptoms of stroke. Not having money to pay for hospital bills was a predictor of late hospital presentation (OR =6.64; 95% CI, (2.05–21.53); p=0.002). The other factors, though not statistically significant included not perceiving stroke as a serious illness (OR = 2.43; 95% CI (0.78–5.51); p=0.083) and unavailability of transport (OR=2.33; 95% CI (0.71–7.56); p=0.161). Predictors for early presentation included receiving knowledge about stroke from the community (OR=0.46; 95% CI (0.15–1.39); p=0.170); seeking help at the hospital (OR=0.50; 95% CI (0.18–1.37); p=0.177) and having a stroke while at the workplace (OR =0.46; 95% CI (0.08–2.72); p=0.389).

Conclusions

Regarding stroke as an emergency that does not require prerequisite payment for services at hospitals and improved community awareness on stroke may improve time taken to present to hospital after the onset of stroke symptoms.

Early Mortality and Associated Factors among Patients with Stroke Admitted to a Large Teaching Hospital in Tanzania

BACKGROUND

Stroke is a major cause of death worldwide and 85.5% of stroke deaths occur in low- and middle-income countries due to stroke. The aim of this study was to investigate correlates and predictors of 30-day mortality in stroke patients in urban Tanzania.

METHODS

A prospective 30-day follow-up study was conducted at the Muhimbili National Hospital, Dar es Salaam, Tanzania. We recruited all patients with stroke seen at the Emergency Medicine Department and medical wards. Patients underwent medical history and physical examination including full neurological examination. For those who met the criteria for the diagnosis of stroke according to the World Health Organization, further data were collected, including cholesterol, creatinine, fasting blood glucose, full blood picture, human immunodeficiency virus serology, and electrocardiogram. Patients were followed up at 30 days from the date of stroke onset. The date and the cause of death of those participants who died within 30 days of stroke onset were recorded.

RESULTS

A total of 224 patients were recruited into the study, with follow-up data available on 186 (83.0%). At 30 days post stroke, 124 patients (66.7%) were still alive. Mortality was significantly higher among stroke patients who were over 65 years of age. Of the 62 who died, 54% died of aspiration pneumonia and 21% of septicemia. Patients with infection were 4.4 times more likely to die than thosewithout (P = .001).

CONCLUSIONS

Poststroke mortality rates were high. Many deaths were potentially preventable.

The Neglected Burden of Stroke in Sub-Saharan Africa

The looming epidemic of stroke and other chronic non-communicable diseases associated with lifestyle and demographic transitions occurring all over the world is increasingly being acknowledged. However, the significance of these trends in the relatively young populations of the countries comprising Sub-Saharan Africa (SSA) is less certain and considerably overshadowed by attention given to the impact of human immunodeficiency virus and other infectious diseases. We undertook a literature review of the burden of stroke in SSA and provide recommendations for future research. Despite the paucity of high quality studies, the mostly hospital-based data and limited community surveys indicate there to be high and increasing rates of stroke affecting people at much younger ages in SSA than in developed countries. In general, awareness, diagnosis and management of stroke are poor, and the associated case fatality and residual disability are high. As elsewhere, elevated blood pressure is the major determinant of stroke but there are also high rates of strokes related to the complications of rheumatic heart disease and other infections. Given high attributable risks exposures in association with rapid ageing and urbanisation in SSA, the future is not bright. Population-based incidence studies are urgently needed to map the profile and outcome of stroke. Such data would provide the necessary evidence base to improve prevention and treatments for stroke alongside current efforts to bring infectious diseases under control in SSA.

Chronic disease, risk factors and disability in adults aged 50 and above living with and without HIV: findings from the Wellbeing of Older People Study in Uganda

BACKGROUND

Data on the prevalence of chronic conditions, their risk factors, and their associations with disability in older people living with and without HIV are scarce in sub-Saharan Africa.

OBJECTIVES

In older people living with and without HIV in sub-Saharan Africa: 1) to describe the prevalence of chronic conditions and their risk factors and 2) to draw attention to associations between chronic conditions and disability.

METHODS

Cross-sectional individual-level survey data from people aged 50 years and over living with and without HIV were analyzed from three study sites in Uganda. Diagnoses of chronic conditions were made through self-report, and disability was determined using the WHO Disability Assessment Schedule (WHODAS). We used ordered logistic regression and calculated predicted probabilities to show differences in the prevalence of multiple chronic conditions across HIV status, age groups, and locality. We used linear regression to determine associations between chronic conditions and the WHODAS.

RESULTS

In total, 471 participants were surveyed; about half the respondents were living with HIV. The prevalence of chronic obstructive pulmonary disease and eye problems (except for those aged 60-69 years) was higher in the HIV-positive participants and increased with age. The prevalence of diabetes and angina was higher in HIV-negative participants. The odds of having one or more compared with no chronic conditions were higher in women (OR 1.6, 95% CI 1.1-2.3) and in those aged 70 years and above (OR 2.1, 95% CI 1.2-3.6). Sleep problems (coefficient 14.2, 95% CI 7.3-21.0) and depression (coefficient 9.4, 95% CI 1.2-17.0) were strongly associated with higher disability scores.

CONCLUSION

Chronic conditions are common in older adults and affect their functioning. Many of these conditions are not currently addressed by health services in Uganda. There is a need to revise health care policy and practice in Uganda to consider the health needs of older people, particularly as the numbers of people living into older age with HIV and other chronic conditions are increasing.

Mental Health in Namibia

Psychological distress is inherently constructed within contexts and the unique, cultural meaning systems that have developed to understand mental illness. Moreover, cultures naturally develop their own systems of healing, grounded in traditional practices. Western psychology and psychiatry have, through globalisation and colonial histories, imposed systems of mental health care and definitions of mental illness. In doing so, local understandings and ways of being regarding mental health have often been eclipsed. This is no less true in Namibia. However, much of the existing mental health literature from Namibia explores mental illness from a Western lens of psychopathology. This article discusses the relevant research about mental illness in Namibia and situates this within related literature from other Southern African countries. Several cultural factors across diverse groups in Namibia are important to more fully understand what mental illness and treatment are throughout this country. The cultural role of diverse conceptualisations of mental illness is discussed in order to explore potential areas of growth in Namibian mental health and intervention. The nature of traditional healing in other Southern African contexts is also addressed, given that although traditional healing exists in Namibia, researchers have not yet explored it within the context of psychological distress. Recommendations for mental health and psychological treatment in Namibia are discussed.

Chronic Diseases in North-West Tanzania and Southern Uganda. Public Perceptions of Terminologies, Aetiologies, Symptoms and Preferred Management

Background

Research has shown that health system utilization is low for chronic diseases (CDs) other than HIV. We describe the knowledge and perceptions of CDs identified from rural and urban communities in north-west Tanzania and southern Uganda.

Methods

Data were collected through a quantitative population survey, a quantitative health facility survey and focus group discussions (FGDs) and in-depth interviews (IDIs) in subgroups of population survey participants. The main focus of this paper is the findings from the FGDs and IDIs.

Results

We conducted 24 FGDs, involving approximately 180 adult participants and IDIs with 116 participants (≥18 years). CDs studied included: asthma/chronic obstructive lung disease (COPD), diabetes, epilepsy, hypertension, cardiac failure and HIV- related disease. The understanding of most chronic conditions involved a combination of biomedical information, gleaned from health facility visits, local people who had suffered from a complaint or knew others who had and beliefs drawn from information shared in the community. The biomedical contribution shows some understanding of the aetiology of a condition and the management of that condition. However, local beliefs for certain conditions (such as epilepsy) suggest that biomedical treatment may be futile and therefore work counter to biomedical prescriptions for management.

Conclusion

Current perceptions of selected CDs may represent a barrier that prevents people from adopting efficacious health and treatment seeking behaviours. Interventions to improve this situation must include efforts to improve the quality of existing health services, so that people can access relevant, reliable and trustworthy services.

Clinics and churches: lifeworlds and health-seeking practices of older women with noncommunicable disease in rural South Africa

Background

In this article we describe a phenomenological lifeworld study based on the theory of communicative action of 13 women with noncommunicable disease (NCDs) in a rural area in South Africa. The purpose of the study was to generate key concepts of health care access and the management of NCDs in a rural South African context.

Methods

The study employed a qualitative methodology with serial semistructured interviews. We used a content analytical approach to analyse key themes and patterns in participants’ narratives of NCDs and health care access.

Results

The findings are reported by theme and include analyses of narrative sequences related to 1) family environment, 2) experiences of NCDs, 3) understandings of the causes of NCDs, 4) accessibility of formal health care services, 5) experiences of formal health care services, 6) treating NCDs, and 7) experiences of informal health care services. The findings suggest that participation in the routines prescribed by formal health care services and reinforced by families and faith-based communities normalises the experience of NCDs to the extent that narratives of NCDs form the background, rather than the focus of broader illness narratives. Such narratives rather tend to focus on significant life events and relationships. The key features of the narratives include connections between social or autobiographical and biological understandings of NCDs, the appropriation of modern concepts of disease in illness narratives, and reflexive commentary on the modern features of NCDs. In the context of such narrative expertise formal health care services have a high level of acceptability in this rural area.

Conclusion

Lifeworld analysis of health care access based on the theory of communicative action places consensual understandings of NCDs and their treatment as central to the health care experience. Our findings suggest that such analyses can facilitate potential feedback processes between health care users and professionals which generate consensus as well as institutional reform within formal health care services.

Changing use of traditional healthcare amongst those dying of HIV related disease and TB in rural South Africa from 2003 - 2011: a retrospective cohort study

BACKGROUND

In 2011 there were 5.5 million HIV infected people in South Africa and 71% of those requiring antiretroviral therapy (ART) received it. The effective integration of traditional medical practitioners and biomedical providers in HIV prevention and care has been demonstrated. However concerns remain that the use of traditional treatments for HIV-related disease may lead to pharmacokinetic interactions between herbal remedies and ART drugs and delay ART initiation. Here we analyse the changing prevalence and determinants of traditional healthcare use amongst those dying of HIV-related disease, pulmonary tuberculosis and other causes in a rural South African community between 2003 and 2011. ART was made available in this area in the latter part of this period.

METHODS

Data was collected during household visits and verbal autopsy interviews. InterVA-4 was used to assign causes of death. Spatial analyses of the distribution of traditional healthcare use were performed. Logistic regression models were developed to test associations of determinants with traditional healthcare use.

RESULTS

There were 5929 deaths in the study population of which 47.7% were caused by HIV-related disease or pulmonary tuberculosis (HIV/AIDS and TB). Traditional healthcare use declined for all deaths, with higher levels throughout for those dying of HIV/AIDS and TB than for those dying of other causes. In 2003-2005, sole use of biomedical treatment was reported for 18.2% of HIV/AIDS and TB deaths and 27.2% of other deaths, by 2008-2011 the figures were 49.9% and 45.3% respectively. In bivariate analyses, higher traditional healthcare use was associated with Mozambican origin, lower education levels, death in 2003-2005 compared to the later time periods, longer illness duration and moderate increases in prior household mortality. In the multivariate model only country of origin, time period and illness duration remained associated.

CONCLUSIONS

There were large decreases in reported traditional healthcare use and increases in the sole use of biomedical treatment amongst those dying of HIV/AIDS and TB. No associations between socio-economic position, age or gender and the likelihood of traditional healthcare use were seen. Further qualitative and quantitative studies are needed to assess whether these figures reflect trends in healthcare use amongst the entire population and the reasons for the temporal changes identified.

The right to traditional, complementary, and alternative health care

BACKGROUND

State parties to human rights conventions and declarations are often faced with the seemingly contradictory problem of having an obligation to protect people from harmful practices while also having an obligation to enable access to culturally appropriate effective healing. As people increasingly migrate across the globe, previous distinctions between 'traditional' and 'complementary and alternative medicine' practices are being transcended. There are connections across transnational healing pathways that link local, national, and global movements of people and knowledge.

OBJECTIVE

This paper contributes to the development of the concept and practice of the right to health in all its forms, exploring the right to traditional, complementary, and alternative health (R2TCAH) across different contexts.

DESIGN

The paper draws on four settings - England, South Africa, Kenya, and Jordan - and is based on key informant interviews and a literature review undertaken in 2010, and updated in 2013. The paper begins by reviewing the international legal context for the right to health. It then considers legal and professional regulations from the global north and south.

RESULTS

Additional research is needed to establish the legal basis, compare regulatory frameworks, and explore patient and provider perspectives of regulation. This leads to being able to make recommendations on how to balance protection from harm and the obligation to ensure culturally appropriate services. Such an exploration must also challenge Western theories of human rights. Key concepts, such as individual harm, consent, and respect of the autonomy of the individual already established and recognised in international health law, could be adopted in the development of a template for future comparative research.

CONCLUSIONS

Exploration of the normative content of the right to health in all its forms will contribute to supporting traditional, complementary, and alternative health service users and providers in terms of access to information, non-discrimination, clarification of state obligations, and accountability.

Knowledge and Perception of Stroke: A Population-Based Survey in Uganda

PURPOSE

This study, designed to complement a large population survey on prevalence of stroke risk factors, assessed knowledge and perception of stroke and associated factors.

METHODS

A population survey was conducted in urban Nansana and rural Busukuma, Wakiso district, central Uganda. Adult participants selected by multistage stratified sampling were interviewed about selected aspects of stroke knowledge and perception in a pretested structured questionnaire.

RESULTS

There were 1616 participants (71.8% urban; 68.4% female; mean age: 39.6 years ± 15.3). Nearly 3/4 did not know any stroke risk factors and warning signs or recognize the brain as the organ affected. Going to hospital (85.2%) was their most preferred response to a stroke event. Visiting herbalists/traditional healers was preferred by less than 1%. At multivariable logistic regression, good knowledge of stroke warning signs and risk factors was associated with tertiary level of education (OR 4.29, 95% CI 2.13-8.62 and OR 5.96, 95% CI 2.94-12.06), resp.) and self-reported diabetes (OR 1.97, 95% CI 1.18-3.32 and OR 1.84, 95% CI 1.04-3.25), resp.).

CONCLUSION

Knowledge about stroke in Uganda is poor although the planned response to a stroke event was adequate. Educational strategies to increase stroke knowledge are urgently needed as a prelude to developing preventive programmes.

Exploring the experience of facilitating self-management with minority ethnic stroke survivors: a qualitative study of therapists' perceptions

PURPOSE

The utility of self-management with people from minority ethnic backgrounds has been questioned, resulting in the development of culturally specific tools. Yet, the use of stroke specific self-management programmes is underexplored in these high risk groups. This article presents the experience of stroke therapists in using a stroke specific self-management programme with stroke survivors from minority ethnic backgrounds.

METHODS

26 stroke therapists with experience of using the self-management programme with stroke survivors from minority ethnic backgrounds participated in semi-structured interviews. These were audio recorded, transcribed verbatim and analysed thematically.

RESULTS

Three themes were identified. One questioned perceived differences in stroke survivors interaction with self-management based on ethnicity. The other themes contrasted with this view demonstrating two areas in which ethnic and cultural attributes were deemed to influence the self-management process both positively and negatively. Aspects of knowledge of health, illness and recovery, religion, family and the professionals themselves are highlighted.

CONCLUSIONS

This study indicates that ethnicity should not be considered a limitation to the use of an individualized stroke specific self-management programme. However, it highlights potential facilitators and barriers, many of which relate to the capacity of the professional to effectively navigate cultural and ethnic differences.

Nurse management of hypertension in rural western Kenya: implementation research to optimize delivery

BACKGROUND

Hypertension is the leading global risk factor for mortality. Hypertension treatment and control rates are low worldwide, and insufficient human resource capacity is among the contributing factors. Thus, a critical component of hypertension management is to develop novel and effective solutions to the human resources challenge. One potential solution is task redistribution and nurse management of hypertension in these settings.

OBJECTIVES

The aim of this study is to investigate whether nurses can effectively reduce blood pressure in hypertensive patients in rural western Kenya and, by extension, throughout sub-Saharan Africa.

METHODS

An initial phase of qualitative inquiry will assess facilitators and barriers of nurse management of hypertension. In addition, we will perform usability and feasibility testing of a novel, electronic tablet-based integrated decision-support and record-keeping tool for the nurses. An impact evaluation of a pilot program for nurse-based management of hypertension will be performed. Finally, a needs-based workforce estimation model will be used to estimate the nurse workforce requirements for stable, long-term treatment of hypertension throughout western Kenya.

FINDINGS

The primary outcome measure of the impact evaluation will be the change in systolic blood pressure of hypertensive individuals assigned to nurse-based management after 1 year of follow-up. The workforce estimation modeling output will be the full-time equivalents of nurses.

CONCLUSIONS

This study will provide evidence regarding the effectiveness of strategies to optimize task redistribution and nurse-based management of hypertension that can be applicable to noncommunicable disease management in low- and middle-income countries.

Self-reported health and health care use in an ageing population in the Agincourt sub-district of rural South Africa

Background

South Africa is experiencing a demographic and epidemiological transition with an increase in population aged 50 years and older and rising prevalence of non-communicable diseases. This, coupled with high HIV and tuberculosis prevalence, puts an already weak health service under greater strain.

Objective

To measure self-reported chronic health conditions and chronic disease risk factors, including smoking and alcohol use, and to establish their association with health care use in a rural South African population aged 50 years or older.

Methods

The Study on Global Ageing and Adult Health (SAGE), in collaboration with the INDEPTH Network and the World Health Organization, was implemented in the Agincourt sub-district in rural northeast South Africa where there is a long-standing health and socio-demographic surveillance system. Household-based interviews were conducted in a random sample of people aged 50 years and older. The interview included questions on self-reported health and health care use, and some physical measurements, including blood pressure and anthropometry.

Results

Four hundred and twenty-five individuals aged 50 years or older participated in the study. Musculoskeletal pain was the most prevalent self-reported condition (41.7%; 95% Confidence Interval [CI] 37.0–46.6) followed by hypertension (31.2%; 95% CI 26.8–35.9) and diabetes (6.1%; 95% CI 4.1–8.9). All self-reported conditions were significantly associated with low self-reported functionality and quality of life, 57% of participants had hypertension, including 44% of those who reported normal blood pressure. A large waist circumference and current alcohol consumption were associated with high risk of hypertension in men, whereas in women, old age, high waist–hip ratio, and less than 6 years of formal education were associated with high risk of hypertension. Only 45% of all participants reported accessing health care in the last 12 months. Those who reported higher use of the health facilities also reported lower levels of functioning and quality of life.

Conclusion

Self-reported chronic health conditions, especially hypertension, had a high prevalence in this population and were strongly associated with higher levels of health care use. The primary health care system in South Africa will need to provide care for people with non-communicable diseases.

Challenges of Postdisaster Intervention in Cultural Context: The Implementation of a Lay Mental Health Worker Project in Postearthquake Haiti

Recent disasters have incited controversy regarding whether and how Western psychology can contribute to postdisaster mental health care across cultures. Drawing from experience implementing a Haitian–United States collaborative intervention for displaced earthquake survivors in Port-au-Prince, we propose that when a model is culturally compatible, participants may benefit from both indigenous and Western psychological perspectives simultaneously, even if these approaches are not entirely congruent. We describe the theoretical basis and development of this train-the-trainer lay mental health worker project, called Soulaje Lespri Moun (Relief for the Spirit), and outline its efforts to present empirically informed psychological content to residents of camps for internally displaced peoples using a culturally appropriate and community-focused framework. We detail the evolution of this project to accommodate shifting conditions postearthquake, as well as challenges faced and ongoing evaluation efforts.

The epidemiology of 'bewitchment' as a lay-reported cause of death in rural South Africa

BACKGROUND

Cases of premature death in Africa may be attributed to witchcraft. In such settings, medical registration of causes of death is rare. To fill this gap, verbal autopsy (VA) methods record signs and symptoms of the deceased before death as well as lay opinion regarding the cause of death; this information is then interpreted to derive a medical cause of death. In the Agincourt Health and Demographic Surveillance Site, South Africa, around 6% of deaths are believed to be due to 'bewitchment' by VA respondents.

METHODS

Using 6874 deaths from the Agincourt Health and Socio-Demographic Surveillance System, the epidemiology of deaths reported as bewitchment was explored, and using medical causes of death derived from VA, the association between perceptions of witchcraft and biomedical causes of death was investigated.

RESULTS

The odds of having one's death reported as being due to bewitchment is significantly higher in children and reproductive-aged women (but not in men) than in older adults. Similarly, sudden deaths or those following an acute illness, deaths occurring before 2001 and those where traditional healthcare was sought are more likely to be reported as being due to bewitchment. Compared with all other deaths, deaths due to external causes are significantly less likely to be attributed to bewitchment, while maternal deaths are significantly more likely to be.

CONCLUSIONS

Understanding how societies interpret the essential factors that affect their health and how health seeking is influenced by local notions and perceived aetiologies of illness and death could better inform sustainable interventions and health promotion efforts.

Stroke: a realistic approach to a growing problem in sub-Saharan Africa is urgently needed

Stroke is an increasing problem in sub-Saharan Africa, even in children. High rates of hypertension, diabetes, alcohol abuse, smoking, insufficient fruit and vegetable consumption, sickle cell disease, HIV infection, antiretroviral use and race are likely contributing factors. Although often considered as related to increasing wealth, stroke is more strongly related to poverty, and in turn increases it. Case-fatality rates are high and premature death and years of life lost are a major problem. We propose an approach to stroke prevention and treatment that takes into account the real situation on the ground and can be applied in sub-Saharan Africa, an area where stroke units are largely not feasible and many patients do not reach hospitals. Involvement of community and faith-based organisations, use of simple diagnostic tests, emphasis on clinical examination to differentiate between haemorrhagic and ischaemic stroke, prompt initiation of aspirin therapy and training of community nurses on essential management of stroke should be urgently implemented.

Nonbiomedical Stroke Practitioners in Aceh

Stroke resources in Indonesia are limited; however, there has been demand to include nonbiomedical practitioners in stroke care. This paper will present a snapshot of available nonbiomedical stroke ‘services’ used by stroke survivors in two subdistricts of Aceh, Indonesia. Data were collected through interviews, observations, focus groups and vignettes with stroke survivors, their carers, biomedical and nonbiomedical stroke practitioners. Two categories of nonbiomedical practitioners were identified, all of whom discussed and demonstrated an understanding and approach to stroke treatment with multiple layers of influence, predominantly, education, religion and culture. There were a number of areas of overlap between the two categories; some of these influences were also evident in the biomedical practitioners.

"I feel like half my body is clogged up": Lay models of stroke in Central Aceh, Indonesia

Stroke in low and middle income countries is an increasing cause of death and disability, with rates and the estimated burden considerably higher than that of high income countries. Lay explanatory models are believed to be one of the major influences on health seeking behaviour and essential to understand for appropriate education strategies. Despite stroke being a considerable health concern in Indonesia and particularly in Aceh, no studies to date have explored lay stroke models in that context. This paper presents the findings of a qualitative study informed by both hermeneutic phenomenology and ethnography. Based in rural communities in Bener Meriah and Aceh Tengah in Central Aceh, Indonesia, data were gathered through interviews, photographs and observations with 11 persons with stroke (aged 32-69 years) and 18 of their carers. Fieldwork was conducted over nine months between 2007 and 2008. The study examined lay concepts of stroke, described as a condition resulting from a local blockage in blood from multiple causes, many of which are not recognised within the biomedical frame. The blockage is understood to be reversible and therefore the condition curable. This understanding is embedded and sustained in the specific political, cultural, religious and social context. The results illustrate similarities and differences with other cross-cultural studies and suggest areas of future research and points of consideration for stroke education strategies.

An overview of cardiovascular risk factor burden in sub-Saharan African countries: a socio-cultural perspective

Background

Sub-Saharan African (SSA) countries are currently experiencing one of the most rapid epidemiological transitions characterized by increasing urbanization and changing lifestyle factors. This has resulted in an increase in the incidence of non-communicable diseases, especially cardiovascular disease (CVD). This double burden of communicable and chronic non-communicable diseases has long-term public health impact as it undermines healthcare systems.

Purpose

The purpose of this paper is to explore the socio-cultural context of CVD risk prevention and treatment in sub-Saharan Africa. We discuss risk factors specific to the SSA context, including poverty, urbanization, developing healthcare systems, traditional healing, lifestyle and socio-cultural factors.

Methodology

We conducted a search on African Journals On-Line, Medline, PubMed, and PsycINFO databases using combinations of the key country/geographic terms, disease and risk factor specific terms such as "diabetes and Congo" and "hypertension and Nigeria". Research articles on clinical trials were excluded from this overview. Contrarily, articles that reported prevalence and incidence data on CVD risk and/or articles that report on CVD risk-related beliefs and behaviors were included. Both qualitative and quantitative articles were included.

Results

The epidemic of CVD in SSA is driven by multiple factors working collectively. Lifestyle factors such as diet, exercise and smoking contribute to the increasing rates of CVD in SSA. Some lifestyle factors are considered gendered in that some are salient for women and others for men. For instance, obesity is a predominant risk factor for women compared to men, but smoking still remains mostly a risk factor for men. Additionally, structural and system level issues such as lack of infrastructure for healthcare, urbanization, poverty and lack of government programs also drive this epidemic and hampers proper prevention, surveillance and treatment efforts.

Conclusion

Using an African-centered cultural framework, the PEN3 model, we explore future directions and efforts to address the epidemic of CVD risk in SSA.

Implications of mortality transition for primary health care in rural South Africa: a population-based surveillance study

BACKGROUND

In southern Africa, a substantial health transition is underway, with the heavy burden of chronic infectious illness (HIV/AIDS and tuberculosis) paralleled by the growing threat of non-communicable diseases. We investigated the extent and nature of this health transition and considered the implications for primary health care.

METHODS

Health and sociodemographic surveillance started in the Agincourt subdistrict, rural South Africa, in 1992. In a population of 70 000, deaths (n=6153) were rigorously monitored with a validated verbal autopsy instrument to establish probable cause. We used age-standardised analyses to investigate the dynamics of the mortality transition by comparing the period 2002-05 with 1992-94.

FINDINGS

Mortality from chronic non-communicable disease ranked highest in adults aged 50 years and older in 1992-94 (41% of deaths [123/298]), whereas acute diarrhoea and malnutrition accounted for 37% of deaths (59/158) in children younger than 5 years. Since then, all-cause mortality increased substantially (risk ratio 1.87 [95% CI 1.73-2.03]; p<0.0001) because of a six-fold rise in deaths from infectious disease affecting most age and sex groups (5.98 [4.85-7.38]; p<0.0001), and a modest increase in deaths from non-communicable disease (1.15 [0.99-1.33]; p=0.066). The change in female risk of death from HIV and tuberculosis (15.06 [8.88-27.76]; p<0.0001) was almost double that of the change in male risk (8.13 [5.55-12.36]; p<0.0001). The burden of disorders requiring chronic care increased disproportionately compared with that requiring acute care (2.63 [2.30-3.01]; p<0.0001 vs 1.31 [1.12-1.55]; p=0.0003).

INTERPRETATION

Mortality from non-communicable disease remains prominent despite the sustained increase in deaths from chronic infectious disease. The implications for primary health-care systems are substantial, with integrated chronic care based on scaled-up delivery of antiretroviral therapy needed to address this expanding burden.

Provider insights about palliative care barriers and facilitators: results of a rapid ethnographic assessment

Palliative care remains underutilized in the United States. This may represent failure of translation of research into practice (diffusion of innovation). Qualitative methods can identify barriers to and facilitators of diffusion of innovation. The aim is to identify potential barriers to and facilitators of inpatient palliative care utilization at a large urban hospital, as articulated by health professionals. Rapid ethnographic assessment methods were used among health professionals with subsequent extraction of predominant themes illuminating factors influencing adoption of palliative care services. In all, 3 stakeholder categories and 7 major themes emerged. Analysis revealed consistent need for organized, cross-disciplinary education/training services and a clearly-defined team approach. Denial at all stakeholder levels and in most themes was a barrier to implementation of palliative care. Consistent, defined educational, policymaking, and procedural standards were requirements for best adoption of palliative care. Denial was a striking obstruction to diffusion of innovation.

Stroke in Rural Areas and Small Communities

The management of stroke in rural and regional areas is variable in both the developed and developing world. Informed by best-practice guidelines and recommendations for systems of stroke care, adaptable models of care that are appropriate for local needs should be devised for rural and regional settings. This review addresses the issue of the provision of appropriate services in rural and regional settings, with particular attention to the barriers involved, according to the classification of Low Human Development Country (LHDC), Medium Human Development Country (MHDC) and High Human Development Country (HHDC). We discuss the need and feasibility of developing implementing stroke care in rural settings according to best-practice recommendations, within models of care adapted to local conditions.

A cross-sectional study of vascular risk factors in a rural South African population: data from the Southern African Stroke Prevention Initiative (SASPI)

BACKGROUND

Rural sub-Saharan Africa is at an early stage of economic and health transition. It is predicted that the 21st century will see a serious added economic burden from non-communicable disease including vascular disease in low-income countries as they progress through the transition. The stage of vascular disease in a population is thought to result from the prevalence of vascular risk factors. Already hypertension and stroke are common in adults in sub-Saharan Africa. Using a multidisciplinary approach we aimed to assess the prevalence of several vascular risk factors in Agincourt, a rural demographic surveillance site in South Africa.

METHODS

We performed a cross sectional random sample survey of adults aged over 35 in Agincourt (population approximately 70 000). Participants were visited at home by a trained nurse who administered a questionnaire, carried out clinical measurements and took a blood sample. From this we assessed participants' history of vascular risk, blood pressure using an OMRON 705 CP monitor, waist circumference, body mass index (BMI), ankle brachial index (ABI), and total and HDL cholesterol.

RESULTS

402 people (24% men) participated. There was a high prevalence of smoking in men, but the number of cigarettes smoked was small. There was a striking difference in mean BMI between men and women (22.8 kg/m2 versus 27.2 kg/m2), but levels of blood pressure were very similar. 43% of participants had a blood pressure greater than 140/90 or were on anti-hypertensive treatment and 37% of participants identified with measured high blood pressure were on pharmacological treatment. 12% of participants had an ABI of < 0.9, sugesting the presence of sub-clinical atheroma. 25.6% of participants had a total cholesterol level > 5 mmol/l.

CONCLUSION

We found a high prevalence of hypertension, obesity in women, and a suggestion of subclinical atheroma despite relatively favourable cholesterol levels in a rural South African population. South Africa is facing the challenge of an emerging epidemic of vascular disease. Research to establish the social determinates of these risk factors and interventions to reduce both individual and population risk are required.

Understanding and managing hypertension in an African sub-district: a multidisciplinary approach

AIMS

To use a multidisciplinary approach to describe the prevalence, lay beliefs, health impact, and treatment of hypertension in the Agincourt sub-district.

METHODS

A multidisciplinary team used a range of methods including a cross-sectional random sample survey of vascular risk factors in adults aged 35 years and older, and rapid ethnographic assessment. People who had suffered a stroke were identified by a screening questionnaire followed by a detailed history and examination by a clinician to confirm the likely diagnosis of stroke. Workshops were held for nurses working in the local clinics and an audit of blood pressure measuring devices was carried out.

RESULTS

Some 43% of the population 35 and over had hypertension. There was no relationship with gender but a strong positive relationship with age. Illnesses were classified by the population as being either African, with personal or social causes, or White/Western, with physical causes. The causes of hypertension were stated to be both physical and social. Main sources of treatment were the clinics and hospitals but people also sought help from churches and traditional healers. Some 84% of stroke survivors had evidence of hypertension. Few people received treatment for hypertension, although good levels of control were achieved in some. Barriers to providing effective treatment included unreliable drug supply and unreliable equipment to measure blood pressure.

CONCLUSIONS

Hypertension is a major problem among older people in Agincourt. There is potential for effective secondary prevention. The potential for primary prevention is less clear. Further information on diet is required.

Living with death in a time of AIDS: a rural South African case study

AIMS

To examine how a rural community profoundly affected by escalating rates of largely AIDS-related deaths of young and middle-aged people makes sense of this phenomenon and its impact on their everyday lives.

METHODS

Data were collected in Agincourt subdistrict, Limpopo Province. Twelve focus groups were constituted according to age and gender and met three times (a total of 36 focus-group discussions [FGDs]). The FGDs explored sequentially people's expectations of their lives in the "new" South Africa, their interpretations of the acceleration of death amongst the young and middle-aged, and their understandings of HIV/AIDS. Discussions were recorded, fully transcribed, and thematically analysed.

RESULTS

Respondents acknowledged escalating death rates in their community, yet few referred directly to HIV/AIDS as the cause. Rather, respondents focused on the social and cultural causes of death, including the erosion of cultural norms and traditions such as cultural taboos on sex. There are many competing versions of what HIV/AIDS is, what causes it and how it is spread, ranging from scientific explanations to conspiracy theories. Findings highlight the relationship between AIDS and other traditional diseases with some respondents suggesting that AIDS is a new form of other longstanding illnesses.

CONCLUSIONS

This study points to the centrality of cultural explanations in understanding "bad death" (AIDS death) in the Agincourt area. Physical illness is understood to be a symptom of "cultural damage". Implications of this for public health practice and research are outlined.

Confronting HIV/AIDS in a South African village: the impact of health-seeking behaviour

Much social science research on HIV/AIDS focuses on its impact within affected communities and how people try to cope with its consequences. Based on fieldwork in rural South Africa, this article shows ways in which the inhabitants of a village react to illness, in general, and the role their reactions play in facilitating the spread of communicable diseases such as HIV/AIDS. There is potentially a strong connection between the manner in which people respond to illness in general, and actual transmission of infection. By influencing the way villagers react to episodes of ill health, folk beliefs about illness and illness causation may create avenues for more people to become infected. This suggests that efforts to combat the HIV/AIDS pandemic cannot succeed without tackling the effects of folk beliefs. Therefore, in addressing the problem of HIV/AIDS, experts should focus on more than disseminating information about cause and transmission, and promoting abstinence, safe sex, and other technocratic fixes. Our findings suggest that people need information to facilitate not only decision-making about how to self-protect against infection, but also appropriate responses when infection has already occurred.

Acute treatment and long-term management of stroke in developing countries

Developing countries have some of the highest stroke mortality rates in the world that account for over two-thirds of stroke deaths worldwide. Hospital-based studies suggest that the patterns of stroke types and causes of stroke differ between developing and developed countries, resulting in differing needs for acute and long-term care. Data on stroke care provision in developing countries are sparse and most of the available studies are biased towards urban settings in reasonably resourced health-care systems. A general overview shows that the quality and quantity of stroke care is largely patchy in low-income and middle-income countries, with areas of excellence intermixed with areas of severe need, depending upon patients' location, socioeconomic status, education, and cultural beliefs. Here we review the available literature on acute and long-term stroke management in developing countries. On the basis of available studies, largely from developed countries, we discuss the need to develop basic organised stroke-unit care in developing countries.

Burden of stroke in black populations in sub-Saharan Africa

Sub-Saharan Africa is undergoing epidemiological transition. Stroke and other vascular diseases increasingly contribute to the burden of disease. There are no systematic reviews of stroke mortality, prevalence, incidence, and case fatality. We combined a thorough search and critical assessment of the published research. Stroke mortality is as high, perhaps higher, than in high-income regions and increases with age in sub-Saharan Africa as in high-income countries, but the absolute number of stroke deaths remains low. There are no adequate community-based stroke incidence studies. Hospital-based incidence is lower than in high-income regions, but higher in young people, possibly due to hospital admission bias. There are no community-based data on case fatality, but hospital-based case fatality is higher than elsewhere. The prevalence of stroke is lower than in high-income regions, but disabling stroke is as prevalent. As the region develops economically, the incidence of stroke and other vascular diseases will increase unless interventions are implemented. Only community-based incidence studies will accurately reveal the burden of stroke.

Use of applied theatre in health research dissemination and data validation: a pilot study from South Africa

This article reports on a pilot study of the use of applied theatre in the dissemination of health research findings and validation of data. The study took place in South Africa, as part of the Southern Africa Stroke Prevention Initiative (SASPI) and was based at the University/Medical Research Council Rural Public Health and Health Transitions Research Unit (also known as the Agincourt Unit). The aim of SASPI was to investigate the prevalence of stroke and understand the social context of stroke. It was decided to use an applied theatre approach for validating the data and disseminating findings from the anthropological component of the study. The pilot study found that applied theatre worked better in smaller community groups. It allowed data validation and it elicited ideas for future interventions resulting from the health research findings. Evaluation methods of the impact of applied theatre as a vehicle for the dissemination and communication of research findings require further development.
