The role of community participation in primary health care: practices of South African health committees.

BACKGROUND: Community participation is an essential component in a primary health care (PHC) and a human rights approach to health. In South Africa, community participation in PHC is organised through health committees linked to all clinics. AIMS: This paper analyses health committees' roles, their degree of influence in decision-making and factors impacting their participation. METHODS: Data were collected through a mixed-methods study consisting of a cross-sectional survey, focus groups, interviews and observations. The findings from the survey were analysed using simple descriptive statistics. The qualitative data were analysed using thematic content analysis. Data on health committees' roles were analysed according to a conceptual framework adapted from the Arnstein ladder of participation to measure the degree of participation. FINDINGS: The study found that 55 per cent of clinics in Cape Town were linked to a health committee. The existing health committees faced sustainability and functionality challenges and primarily practised a form of limited participation. Their decision-making influence was curtailed, and they mainly functioned as a voluntary workforce assisting clinics with health promotion talks and day-to-day operational tasks. Several factors impacted health committee participation, including lack of clarity on health committees' roles, health committee members' skills, attitudes of facility managers and ward councillors, limited resources and support and lack of recognition. CONCLUSIONS: To create meaningful participation, health committee roles should be defined in accordance with a PHC and human rights framework. Their primary role should be to function as health governance structures at facility level, but they should also have access to influence policy development. Consideration should be given to their potential involvement in addressing social determinants of health. Effective participation requires an enabling environment, including support, financial resources and training.

Assessing Intertemporal Socioeconomic Inequalities in Alcohol Consumption in South Africa.

Background: This paper assesses changes in the socioeconomic inequality in alcohol consumption by exploring whether alcohol consumption (current and binge drinkers) is more prevalent among the wealthier (pro-rich) or poorer (pro-poor) group over time. Methods: Data come from the 2008, 2010/11, 2012, and 2014/15 waves of the National Income Dynamics Study (NIDS). Various equity stratifiers (sex, age, race, and rural/urban) are used to analyze the prevalence of alcohol consumption and to investigate differences in socioeconomic inequalities. Changes in socioeconomic inequality in alcohol consumption between 2008 and 2014/15 were also assessed using the concentration index. Results: Current drinkers were more concentrated among richer South Africans, while binge drinkers were concentrated among the poorer population. For current drinkers, irrespective of sex, race, age, and urban, socioeconomic inequality in alcohol consumption had become less pro-rich between 2008 and 2014/15; while inequality in binge drinking, outside of the Asian/Indian and rural categories, had become less pro-poor between 2008 and 2014/15. Conclusion: The results show evidence that binge drinking is a bigger problem among those of low-SES, young individuals, male and African populations. This paper concludes that the SA government should continue to push forward policies aiming to reduce the prevalence of binge drinking.

Attitudes and practices of public health academics towards research funding from for-profit organizations: cross-sectional survey.

OBJECTIVES: The growing trend of for-profit organization (FPO)-funded university research is concerning because resultant potential conflicts of interest might lead to biases in methods, results, and interpretation. For public health academic programmes, receiving funds from FPOs whose products have negative health implications may be particularly problematic. METHODS: A cross-sectional survey assessed attitudes and practices of public health academics towards accepting funding from FPOs. The sampling frame included universities in five world regions offering a graduate degree in public health; 166 academics responded. Descriptive, bivariate, and logistic regression analyses were conducted. RESULTS: Over half of respondents were in favour of accepting funding from FPOs; attitudes differed by world region and gender but not by rank, contract status, % salary offset required, primary identity, or exposure to an ethics course. In the last 5 years, almost 20% of respondents had received funding from a FPO. Sixty per cent of respondents agreed that there was potential for bias in seven aspects of the research process, when funds were from FPOs. CONCLUSIONS: Globally, public health academics should increase dialogue around the potential harms of research and practice funded by FPOs.

Alcohol Outlet Density and Deprivation in Six Towns in Bergrivier Municipality before and after Legislative Restrictions.

Introduction. In 2016, after the Western Cape Liquor Act was enacted, alcohol outlets were mapped in the six towns from a previous 2008 study to determine: (1) alcohol outlet density; (2) the association between deprivation and alcohol outlet density; (3) geospatial trends of alcohol outlet densities; and (4) the impact of alcohol legislation. Methods. Latitude and longitude coordinates were collected of legal and illegal alcohol outlets, and alcohol outlet density was calculated for legal, illegal and total alcohol outlets by km2 and per 1000 persons. To determine the impact of legislation, t-tests and hot spot analyses were calculated for both 2008 and 2016 studies. Spearman coefficients estimated the relationship between alcohol outlet density and deprivation. Results. Although not statistically significant, the number of alcohol outlets and the density per 1000 population declined by about 12% and 34%, respectively. Illegal outlets were still more likely to be located in more deprived areas, and legal outlets in less deprived areas; and a reduction or addition of a few outlets can change a town's hot spot status. Conclusions. Further studies with larger sample sizes might help to clarify the impacts of the Liquor Act, and the more recent 2017 Alcohol-Related Harms Reduction Policy on alcohol outlet density in the province.

Career Paths of Public Health Medicine Specialists in South Africa.

Public health (PH) skills are core to building responsive and appropriate health systems, and PH personnel including medical specialists are embedded in many countries' health systems. In South Africa, the medical specialty in PH, Public Health Medicine (PHM), has existed for over 40 years. Four years of accredited training plus success in a single national exit exam allows specialist registration with the Health Professions Council of South Africa (HPCSA). However, there are few posts designated specifically for PHM specialists in SA's health system. In view of uncertain roles, this research was designed to determine specialists' career paths, their work, job satisfaction, and perspectives on the future of the specialty. We combined three databases to generate the study population and invited all specialists to participate in an online or hard-copy survey. We found that in 2010, PHM was a small specialty of less 200 physicians. Of the 151 contactable, eligible physicians, 55.6% completed the questionnaire. Participants represented an aging group (median age = 49) of specialists and recent graduates were increasingly women. They largely worked in academic institutions (as managers, teachers, and researchers) and in the public sector health system; were motivated by a sense of social justice and their training was formative, exposing them to work settings which they later entered; were largely highly satisfied at work, but many worked in non-specialist positions. Indeed, one fifth had not registered with the HPCSA as specialists. They were concerned about the specialty's poor visibility and identity, but did not see other PH professionals as a threat. They believed that the specialty should refine its competencies, demonstrate its value and advocate for service positions at all levels of the public sector health service. PHM has a contribution to make-reorienting services to protect communities, preventing ill health, analyzing disease burdens locally, identifying innovations in a resource-constrained health service, largely preoccupied with curative care services.

Usability of existing alcohol survey data in South Africa: a qualitative analysis.

OBJECTIVE: This paper assesses the usability of existing alcohol survey data in South Africa (SA) by documenting the type of data available, identifying what possible analyses could be done using these existing datasets in SA and exploring limitations of the datasets. SETTINGS: A desktop review and in-depth semistructured interviews were used to identify existing alcohol surveys in SA and assess their usability. PARTICIPANTS: We interviewed 10 key researchers in alcohol policies and health economics in SA (four women and six men). It consisted of academic/researchers (n=6), government officials (n=3) and the alcohol industry (n=1). PRIMARY AND SECONDARY OUTCOME MEASURES: The desktop review examined datasets for the level of the data, geographical coverage, the population surveyed, year of data collection, available covariables, analyses possible and limitations of the data. The 10 in-depth interviews with key researchers explored informant's perspective on the usability of existing alcohol datasets in SA. RESULTS: In SA, alcohol data constraints are mainly attributed to accessibility restrictions on survey data, limited geographical coverage, lack of systematic and standardised measurement of alcohol, infrequency of surveys and the lack of transparency and public availability of industry data on production, distribution and consumption. CONCLUSION: The International Alcohol Control survey or a similar framework survey focusing on substance abuse should be considered for implementation at the national level. Also, alcohol research data funded by the taxpayers' money and alcohol industry data should be made publicly available.

Stakeholders' perspectives on Public Health Medicine in South Africa.

South Africa (SA) is reforming its health system in preparation for an anticipated national health insurance (NHI) scheme that aims to improve the delivery of affordable, equitable, accessible health care. Public health (PH) language is explicit in the policy and skilled PH professionals would be expected to play a key role in its implementation. In South Africa, training of doctors as Public Health Medicine (PHM) specialists is funded by the state, yet there are few positions for PHM specialists in the health services. We explored stakeholders' perspectives about this absence, and their views on PHM specialist' roles and contribution in an era of health reform. A qualitative study was conducted in 2012-13, using in-depth interviews with thematic analysis, which elicited perspectives of 31 key stakeholders nationally reflecting diverse employer and institutional backgrounds. While some were surprised by the absence of PH professionals in SA's health system, most agreed the reason was due to factors internal to the profession, such as its low profile and uncertain identity. External factors such as legislation and political preferences for health managers impacted on the employment of PH professionals. However, given the competencies required to implement an ambitious restructuring of the health sector, all believed that PH and PHM personnel were vital. In view of the health system's dominant curative orientation, embedding PH personnel in the services should ensure that health protection, promotion and prevention strategies will inform health priorities. This study, the first known from a low and middle-income country, contributes to the international literature about the identity and roles of PHM physicians, who are versatile professionals with broad skills-sets. In SA, through consultation with health sector employers about potential roles, curricular redesign and trainee recruitment, PHM can graduate fit-for-purpose specialists to work in a range of institutions to address health system reform.

Equity in household spending on alcoholic beverages in South Africa: assessing changes between 1995 and 2011.

BACKGROUND: Globally, alcohol consumption accounts for a substantial burden of disease, which translates into high social and economic costs. To address this burden, several policies (e.g. age and trading hour restrictions, increasing alcohol taxation) were implemented. Despite the existence of these policies evidence shows that alcohol misuse and alcohol-related harms have increased in South Africa over recent years. The objective of this paper is to assess progressivity and the changes in progressivity of alcohol expenditure at the household level in South Africa using datasets that span 15 years. METHODS: Data come from the 1995, 2000, 2005/06 and 2010/11 South Africa Income Expenditure Survey. Distribution of spending on alcoholic beverages were analyzed using standard methodologies. Changes in progressivity between 1995 and 2000, and between 2005/06 and 2010/11 were also assessed using the Kakwani index. RESULTS: Alcohol spending was regressive between 1995 and 2011 as the fraction of poorer households' expenditure spent on alcohol beverage exceeds that for the richest households. Also, the difference in Kakwani indexes of progressivity indicates that spending on alcoholic beverages has become less regressive between the same time periods. CONCLUSION: The results show no evidence that alcohol policy including taxation increased regressivity. Thus, there is an opportunity to further reduce the regressivity using coherent alcohol policies. This paper concludes that there is a need for further research to unpack why alcohol spending became less regressive over the years that goes beyond just looking at changes in the distribution of alcohol expenditure.

The health impacts of extractive industry transnational corporations: a study of Rio Tinto in Australia and Southern Africa.

BACKGROUND: Operations of transnational corporations (TNCs) affect population health through production methods, shaping social determinants of health, or by influencing regulation of their activities. Research on community exposures to TNC practices and policies has been limited. Our research on extractive industries examined Rio Tinto in Australia and Southern Africa to test methods for assessing the health impacts of corporates in high and middle income jurisdictions with different regulatory frameworks. METHODS: We adapted existing Health Impact Assessment methods. Data identifying potential impacts were sourced through media analysis, document analysis, company literature and semi-structured interviews. The data were mapped against a corporate health impact assessment framework (CHIA) which included Rio Tinto's political and business practices; productions; and workforce, social, environmental and economic conditions. RESULTS: Both positive and detrimental aspects of Rio Tinto's operations were identified. Requirements imposed by Rio Tinto on its global supply chain are likely to have positive health impacts for workers. However, political lobbying and membership of representative organisations can influence government policy in ways that are unfavourable to health and equity. Positive impacts include provision of direct employment under decent working conditions, but countered by an increase in precariousness of employment. Commitments to upholding sustainable development principles are undermined by limited site remediation and other environmental impacts. Positive contributions are made to national and local economies but then undermined by business strategies that include tax minimisation. CONCLUSION: Our study confirmed that it is possible to undertake a CHIA on an extractive industry TNC. The different methods provided sufficient information to understand the need to strengthen regulations that are conducive to health; the opportunity for Rio Tinto to extend corporate responsibility initiatives and support their social licence to operate; and for civil society actors to inform their advocacy towards improving health and equity outcomes from TNC operations.

Using Health Committees to Promote Community Participation as a Social Determinant of the Right to Health: Lessons from Uganda and South Africa.

Community participation is not only a human right in itself but an essential underlying determinant for realizing the right to health, since it enables communities to be active and informed participants in the creation of a responsive health system that serves them efficiently. As acknowledged by the Rio Political Declaration on Social Determinants of Health, participatory processes are important in policymaking and in the implementation of laws relating to health. Collective deliberation improves both community development and health system governance, resulting in more reasoned, informed, and public-oriented decisions.1 More recently, attention has focused on the elements of health system governance that enable greater responsiveness to community needs. However, there is relatively little by way of interventions linking human rights approaches to governance in ways that recognize participation as a critical social determinant of the right to health. This paper provides perspectives from a three-year intervention whose general objective was to develop and test models of good practice for health committees in South Africa and Uganda. It describes the aspects that we found critical for enhancing the potential of such committees in driving community participation as a social determinant of the right to health.

Missing knowledge of gendered power relations among non-governmental organisations doing right to health work: a case study from South Africa.

BACKGROUND: Despite 20 years of democracy, South Africa still suffers from profound health inequalities. Gender roles and norms are associated with individuals' vulnerability that lead to ill-health. For instance, gender inequality influences women's access to health care and women's agency to make health-related decisions. This paper explores gender-awareness and inclusivity in organisations that advocate for the right to health in South Africa, and analyses how this knowledge impacts their work? METHODS: In total, 10 in-depth interviews were conducted with members of The Learning Network for Health and Human Rights (LN), a network of universities and Civil Society Organisations (CSOs) which is explicitly committed to advancing the right to health, but not explicitly gendered in its orientation. RESULTS: The results show that there is a discrepancy in knowledge around gender and gendered power relations between LN members. This discrepancy in understanding gendered power relations suggests that gender is 'rendered invisible' within the LN, which impacts the way the LN advocates for the right to health. CONCLUSIONS: Even organizations that work on health rights of women might be unaware of the possibility of gender invisibility within their organisational structures.

Unpacking policy formulation and industry influence: the case of the draft control of marketing of alcoholic beverages bill in South Africa.

Alcohol is a major contributor to the Non-Communicable Disease burden in South Africa. In 2000, 7.1% of all deaths and 7% of total disability-adjusted life years were ascribed to alcohol-related harm in the country. Regulations proposed to restrict alcohol advertising in South Africa present an evidence-based upstream intervention. Research on policy formulation in low- and middle-income countries is limited. This study aims to describe and explore the policy formulation process of the 2013 draft Control of Marketing of Alcoholic Beverages Bill in South Africa between March 2011 and May 2017. Recognising the centrality of affected actors in policy-making processes, the study focused on the alcohol industry as a central actor affected by the policy, to understand how they-together with other actors-may influence the policy formulation process. A qualitative case study approach was used, involving a stakeholder mapping, 10 in-depth interviews, and review of approximately 240 documents. A policy formulation conceptual framework was successfully applied as a lens to describe a complex policy formulation process. Key factors shaping policy formulation included: (1) competing and shared values-different stakeholders promote conflicting ideals for policymaking; (2) inter-department jostling-different government departments seek to protect their own functions, hindering policy development; (3) stakeholder consultation in democratic policymaking-policy formulation requires consultations even with those opposed to regulation and (4) battle for evidence-evidence is used strategically by all parties to shape perceptions and leverage positions. This research (1) contributes to building an integrated body of knowledge on policy formulation in low- and middle-income countries; (2) shows that achieving policy coherence across government departments poses a major challenge to achieving effective health policy formulation and (3) shows that networks of actors with commercial and financial interests use diverse strategies to influence policy formulation processes to avoid regulation.

Access to palliative care in HIV services in Cape Town.

This paper examines access to palliative care (PC) for patients with HIV, part of a study investigating access to PC for patients with chronic diseases. Studies highlight gaps in symptom management and psychosocial care for People living with HIV (PLHIV) and thus the need to integrate PC into HIV services. The aim of the study was to describe the access of patients with advanced chronic illness to PC services. METHODOLOGY: this was a prospective cohort study conducted over six months. Participants were recruited from patients living with HIV with CD4 counts of <200 cells/mm3, patients with advanced cancer and patients diagnosed with motor neurone disease. All HIV patients were on anti-retroviral treatment. Participants responded to a questionnaire including the APCA African Palliative Outcome Scale (POS), a validated palliative outcome scale, as a measure of care at first visit and telephonically once a month for 6 months. RESULTS: Seventy-nine HIV patients were recruited to the study. During the study 6 PLHIV died and no HIV patients were referred to PC services. A significant finding is that most patient outcomes improved for HIV patients. Pain reduced from 1.83 to 0.86; symptoms reduced from 2.41 to 0.49; worry reduced from 2.17 to 0.35. Spiritual well-being also improved - life worthwhile from 3.56 to 4.74 and at peace from 3.63 to 4.86; all measures out of 5. A small sub-set of this cohort (7.7%) experienced high pain levels not controlled during the study. DISCUSSION: Few patients were referred to PC services despite 6 HIV deaths during the study. Patients attending HIV clinics received good PC in conjunction with HAART, suggesting that PC appears to be well integrated into routine HIV care. It is suggested that patients with severe problems including those who died would have benefitted from referral to PC.

Motivations of South African physicians specialising in public health.

BACKGROUND: South African physicians can specialise in public health through a four-year 'registrar' programme. Despite national health policies that seemingly value public health (PH) approaches, the Public Health Medicine (PHM) speciality is largely invisible in the health services. Nevertheless, many physicians enrol for specialist training. OBJECTIVES: This study investigated physicians' motivations for specialising in PHM, their intended career paths, perceptions of training, and perspectives about the future of the speciality. METHODS: Focus groups and in-depth interviews were conducted with specialists-in-training and newly qualified specialists, and thematic analysis of transcripts was performed. RESULTS: Motivations, often driven by difficult experiences as young physicians in poorly resourced clinical settings, stemmed from a commitment to improving communities' health and desire to impact on perceived failing health systems. Rather than 'exiting' the South African health service, selecting PHM specialist training enacted participants' 'loyalty' to population health. Participants anticipated carving out their own careers due to an absence of public sector career paths. They believed specialists' contribution centred on providing 'public health intelligence' - finding and interpreting information; supporting services through management and leadership; and inputting into policymaking and planning. CONCLUSIONS: Competencies of PHM specialists should be refined to inform and improve management of this scarce human resource for health. This is particularly important given the proposed major health reforms towards universal health coverage in South Africa presently. In addition, findings highlight the importance of physicians' early work experiences where avenues for expressing 'voice', mediated by 'loyalty', could be utilised to improve public sector health systems.

"They must understand we are people": Pregnancy and maternity service use among signing Deaf women in Cape Town.

BACKGROUND: Women with disabilities are at disproportionate risk for adverse pregnancy outcomes, however, there is limited information on their pregnancy histories. This mixed-methods study focuses on signing Deaf women whose access to health care may be compromised by language barriers related to their disability. OBJECTIVE: To describe and compare the pregnancy outcomes and maternity service use of a sample of signing Deaf women of child-bearing age in Cape Town to the population of the Western Cape of South Africa. METHODS: We interviewed 42 Deaf women selected by non-probability snowball sampling, using a structured questionnaire in South African Sign Language in Cape Town in July 2016. RESULTS: Average parity of the sample was similar to that of the Western Cape population. Most women had one or two children (74%). Thirty-one percent of women had experienced a miscarriage and 19% had terminated a pregnancy. Almost all women (96%) attended at least one antenatal appointment during their pregnancies, and all deliveries occurred at a health facility. Women primarily relied on writing to communicate during antenatal visits and labor/delivery. The majority of women reported communication issues due to limited interpretation services, and some reported experiencing mistreatment from hospital staff. CONCLUSION: This study provides novel information on the pregnancy histories of Deaf women. While maternal service usage was high, the quality of services were inadequate with reports of linguistic barriers and mistreatment. Findings suggest the need to improve maternity care for Deaf women through implementing interpretation services and providing sensitivity training to health care providers.

The epidemiology, pathogenesis, transmission, diagnosis, and management of multidrug-resistant, extensively drug-resistant, and incurable tuberculosis.

Global tuberculosis incidence has declined marginally over the past decade, and tuberculosis remains out of control in several parts of the world including Africa and Asia. Although tuberculosis control has been effective in some regions of the world, these gains are threatened by the increasing burden of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis. XDR tuberculosis has evolved in several tuberculosis-endemic countries to drug-incurable or programmatically incurable tuberculosis (totally drug-resistant tuberculosis). This poses several challenges similar to those encountered in the pre-chemotherapy era, including the inability to cure tuberculosis, high mortality, and the need for alternative methods to prevent disease transmission. This phenomenon mirrors the worldwide increase in antimicrobial resistance and the emergence of other MDR pathogens, such as malaria, HIV, and Gram-negative bacteria. MDR and XDR tuberculosis are associated with high morbidity and substantial mortality, are a threat to health-care workers, prohibitively expensive to treat, and are therefore a serious public health problem. In this Commission, we examine several aspects of drug-resistant tuberculosis. The traditional view that acquired resistance to antituberculous drugs is driven by poor compliance and programmatic failure is now being questioned, and several lines of evidence suggest that alternative mechanisms-including pharmacokinetic variability, induction of efflux pumps that transport the drug out of cells, and suboptimal drug penetration into tuberculosis lesions-are likely crucial to the pathogenesis of drug-resistant tuberculosis. These factors have implications for the design of new interventions, drug delivery and dosing mechanisms, and public health policy. We discuss epidemiology and transmission dynamics, including new insights into the fundamental biology of transmission, and we review the utility of newer diagnostic tools, including molecular tests and next-generation whole-genome sequencing, and their potential for clinical effectiveness. Relevant research priorities are highlighted, including optimal medical and surgical management, the role of newer and repurposed drugs (including bedaquiline, delamanid, and linezolid), pharmacokinetic and pharmacodynamic considerations, preventive strategies (such as prophylaxis in MDR and XDR contacts), palliative and patient-orientated care aspects, and medicolegal and ethical issues.

Undereporting of acute pesticide poisoning in Tanzania: modelling results from two cross-sectional studies.

BACKGROUND: Acute pesticide poisoning (APP) is known to cause serious injuries to end users globally but the magnitude of this problem in Tanzania is not well known. This study aimed to determine the extent and pattern of underreporting of APP in Tanzania to inform the development of a surveillance system and appropriate interventions. METHODS: This study integrates findings from two recent Tanzanian studies. A household survey established the proportion of poisoned farmers in a typical rural area who reported to hospital for a pesticide poisoning. Only 5 of the 112 farmers who reported attending hospital due to poisonings could be traced in medical records at the facilities they claimed to have attended. The 95% confidence interval for this ratio (5/112) was used to generate a high and low boundary for the estimates. Three under-estimation factors were generated for sensitivity analysis to adjust for under-reporting. A review of health facilities in three regions of Tanzania collected prospective data on admissions for APP in 2006 to generate population-based APP incidence rates stratified by circumstances of poisoning (occupational, accidental, suicide, and unknown). Sensitivity analysis was conducted involving adjustment for high and low boundaries of the under-reporting of occupational APP and an adjustment for different scenario allocations of cases with 'unknown' circumstances to different combinations of known circumstances. RESULTS: The study estimated the rate of occupational poisoning as ranging from 11.3-37.7 cases/million to 84.3-279.9 cases per million. The rate of all poisonings (occupational and non-occupational) ranged from 24.45-48.01 cases per million to 97.37-290.29 cases per million. Depending on the choice of scenario and under-reporting correction factor used, occupational APP could comprise from 52.2 to 96% of all APP cases. CONCLUSION: The study confirms that data on APP in Tanzanian hospitals are poorly reported and that occupational circumstances are particularly overlooked in routine facility-based surveillance. Occupational APP needs to be taken more seriously in addressing prevention measures. A comprehensive surveillance system for APP should consider multiple data sources including community self-reporting in order to achieve better coverage.
