BACKGROUND: South Africa (SA) has embarked on a process to implement universal health coverage (UHC) funded by National Health Insurance (NHI). The 2019 NHI Bill proposes creation of a health technology assessment (HTA) body to inform decisions about which interventions NHI funds will cover under UHC. In practice, HTA often relies mainly on economic evaluations of cost-effectiveness and budget impact, with less attention to the systematic, specific consideration of important social, organisational and ethical impacts of the health technology in question. In this context, the South African Values and Ethics for Universal Health Coverage (SAVE-UHC) research project recognised an opportunity to help shape the health priority-setting process by providing a way to take account of multiple, ethically relevant considerations that reflect SA values. The SAVE-UHC Research Team developed and tested an SA-specific Ethics Framework for HTA assessment and analysisOBJECTIVES: To develop and test an Ethics Framework for use in the SA context for health priority-settingMETHODS: The Framework was developed iteratively by the authors and a multidisciplinary panel (18 participants) over a period of 18 months, using the principles outlined in the 2015 NHI White Paper as a starting point. The provisional Ethics Framework was then tested with multi-stakeholder simulated appraisal committees (SACs) in three provinces. The membership of each SAC roughly reflected the composition of a potential SA HTA committee. The deliberations and dedicated focus group discussions after each SAC meeting were recorded, analysed and used to refine the Framework, which was presented to the Working Group for review, comment and final approvalRESULTS: This article describes the 12 domains of the Framework. The first four (Burden of the Health Condition, Expected Health Benefits and Harms, Cost-Effectiveness Analysis, and Budget Impact) are commonly used in HTA assessments, and a further eight cover the other ethical domains. These are Equity, Respect and Dignity, Impacts on Personal Financial Situation, Forming and Maintaining Important Personal Relationships, Ease of Suffering, Impact on Safety and Security, Solidarity and Social Cohesion, and Systems Factors and Constraints. In each domain are questions and prompts to enable use of the Framework by both analysts and assessors. Issues that arose, such as weighting of the domains and the availability of SA evidence, were discussed by the SACsCONCLUSIONS: The Ethics Framework is intended for use in priority-setting within an HTA process. The Framework was well accepted by a diverse group of stakeholders. The final version will be a useful tool not only for HTA and other priority-setting processes in SA, but also for future efforts to create HTA methods in SA and elsewhere

BACKGROUND. Evidence-informed priority setting is vital to improved investment in public health interventions. This is particularly important as South Africa (SA) makes the shift to universal health coverage and institution of National Health Insurance. OBJECTIVES. To measure the financial impact of increasing the demand for modern contraceptive methods in the SA public health sector. We estimated the total cost of providing contraceptives, and specifically the budgetary impact of premature removals of long-acting reversible contraceptives. METHODS. We created a deterministic model in Microsoft Excel to estimate the costs of contraception provision over a 5-year time horizon (2018 - 2023) from a healthcare provider perspective. Only direct costs of service provision were considered, including drugs, supplies and personnel time. Costs were not discounted owing to the short time horizon. Scenario analyses were conducted to test uncertainty. RESULTS. The base-case cost of current contraceptive use in 2018 was estimated to be ZAR1.64 billion (ZAR29 per capita). Injectable contraceptives accounted for ~47% of total costs. To meet the total demand for family planning, SA would have to spend ~30% more than the estimate for current contraceptive use. In the year 2023, the 'current use' of modern contraceptives would increase to ZAR2.2 billion, and fulfilling the total demand for family planning would require ZAR2.9 billion. The base-case cost of implantable contraceptives was estimated at ZAR54 million. Assuming a normal removal rate, the use of implants is projected to increase by 20% during the 5-year period between 2019 and 2023, with an estimated 46% increase in costs. The cost of early removal of Implanon NXT is estimated at ZAR75 million, with total contraception costs estimated at ZAR102 million in 2019, compared with ZAR56 million when a normal removal rate is applied. CONCLUSIONS. The costs of scaling up modern contraceptives in SA are substantial. Early and premature removals of implantable contraceptives are costly to the nation and must be minimised. The government should consider conducting appropriate health technology assessments to inform the introduction of new public health interventions as SA makes the shift to universal health coverage by means of National Health Insurance.

BACKGROUND: Early-life exposure to excess sugar affects eating behaviour and creates a predisposition to non-communicable diseases (NCDs). While reducing sugar consumption has been high on the public health agenda, little is known about the sugar content of baby foodsOBJECTIVES: To describe and analyse the sugar content of baby foods in South Africa (SAMETHODS: A cross-sectional study was conducted to analyse the sugar content of baby foods. The study sample included commercially available baby foods targeted at children aged <12 months, sold in supermarkets and by other major retailers in SA. Primary data were obtained from the packaging, and sugar content was compared with recommended intake guidelines. Bivariate analyses were conducted to determine whether there were any associations between the sugar content, added sugar and the characteristics of foodsRESULTS: Over 70% of products were sweet in taste, with one in four containing added sugars. Sugar content was high in 78% of the foods sampled. Over 80% of cereals and pureed desserts contained added sugar. Fewer than 10% of pureed composite meal and pureed fruit and vegetable categories contained added sugar. Most products adhered to SA labelling standards, but none had front-of-pack nutritional informationCONCLUSIONS: The SA baby food market is characterised by products with a high sugar content, promoting an environment that encourages development of sweet-taste preferences and in the long term contributing to the rising burden of NCDs. There is an urgent need for mandatory regulation of sugar in baby foods

BACKGROUND: South Africa (SA) is in the process of implementing National Health Insurance (NHI), which will require co-ordination of health provision across sectors and levels of care. Clinical practice guidelines (CPGs) are tools for standardising and implementing care, and are intended to influence clinical decision-making with consequences for patient outcomes, health system costs and resource use. Under NHI, CPGs will be used to guide the provision of healthcare for South Africans. It is therefore important to explore the current landscape of CPG developers and development. OBJECTIVE: To identify and describe all CPGs available in the public domain produced by SA developers for the SA context. METHODS: We conducted a cross-sectional evaluation using a two-part search process: an iterative, electronic search of grey literature and relevant websites (161 websites searched), and a systematic search for peer-reviewed literature (PubMed) after publication year 2000. CPGs were identified, and data were extracted and categorised by two independent reviewers. Any discrepancies were referred to a third reviewer. Data extracted included a description of the developer, condition, and reporting of items associated with CPG quality. RESULTS: A search conducted in May 2017 identified 285 CPGs published after January 2000. Of those, 171 had been developed in the past 5 years. Developers included the national and provincial departments of health (DoH), professional societies and associations, ad hoc collaborations of clinicians, and the Council for Medical Schemes. Topics varied by developer; DoH CPGs focused on high-burden conditions (HIV/AIDS, tuberculosis and malaria), and other developers focused on non-communicable diseases. A conflict of interest statement was included in 23% of CPGs developed by societies or clinicians, compared with 4% of DoH CPGs. CONCLUSION: Accessing CPGs was challenging and required extensive searching. SA has many contributors to CPG development from the public and private sectors and across disciplines, but there is no formal co-ordination or prioritisation of topics for CPG development. Different versions of the CPGs were identified and key quality items were poorly reported, potentially affecting the usability and credibility of those available. There was substantial variation in CPG comprehensiveness and methodological approach. Establishing a national CPG co-ordinating unit responsible for developing standards for CPG development along with clinical quality standards, and supporting high-quality CPG development, is one essential step for moving forward with NHI.

Improving access to basic surgical interventions has great potential to improve the length and quality of life of many people in low- and middle-income countries (LMICs). However, research has shown that current access to surgical interventions is limited, and initiatives such as the Lancet Commission on Global Surgery 2030 advocate for improved access to basic surgical interventions for all. As the needs, health system context and available budgets in each country will be different, a critical component of effective local scale-up of surgical interventions will be to use tools and processes of health technology assessment (HTA). HTA has traditionally been used in high-income countries to make decisions about which medicines and devices should be available in a health system, but its central concepts, such as assessing clinical effectiveness, cost-effectiveness and feasibility, appraising all available evidence, and incorporating wider health systems objectives in decision-making, can be applied to decisons about how LMICs can best utilise basic surgical interventions from within available resources - in essence, to focus spending on the 'best buys'. As South Africa (SA) moves towards National Health Insurance (NHI), HTA functions will be strengthened. There is potential for SA to lead the practice of application of HTA to decisions about how basic surgical interventions are chosen and implemented, contributing to the success and sustainability of NHI in SA and the health of people in LMICs worldwide.

BACKGROUND. Health information systems for monitoring chronic non-communicable diseases (NCDs) in South Africa (SA) are relatively less advanced than those for infectious diseases (particularly tuberculosis and HIV) and for maternal and child health. NCDs are now the largest cause of premature mortality owing to exposure to risk factors arising from obesity that include physical inactivity and accessible, cheap but unhealthy diets. The National Strategic Plan for the Prevention and Control of Non-Communicable Diseases 2013 - 17 developed by the SA National Department of Health outlines targets and monitoring priorities. OBJECTIVES. To assess data sources relevant for monitoring NCDs and their risk factors by identifying the strengths and weaknesses, including usability and availability, of surveys and routine systems focusing at national and certain sub-national levels. METHODS. Publicly available survey and routine data sources were assessed for variables collected, their characteristics, frequency of data collection, geographical coverage and data availability. RESULTS. Survey data sources were found to be quite different in the way data variables are collected, their geographical coverage and also availability, while the main weakness of routine data sources was poor quality of data. CONCLUSIONS. To provide a sound basis for monitoring progress of NCDs and related risk factors, we recommend harmonising and strengthening available SA data sources in terms of data quality, definitions, categories used, timeliness, disease coverage and biomarker measurement.

The prevalence of diabetes in South Africa is increasing rapidly, and diabetes is a significant cause of blindness. Diabetic complications can induce a cycle of poverty for affected families. Early detection of retinopathy and appropriate management can prevent blindness. Screening for retinopathy using a mobile retinal camera is highly cost-effective, with costs of screening and follow-up treatment being less than the expense of one year of a disability grant. Such a programme is a prime example of a 'best buy' that should be part of the national diabetes care package.

South Africa has a 'quadruple burden of disease'. One way to reduce this burden, and address the social determinants of health and social inequity, could be through health promotion interventions driven by an independent Health Promotion and Development Foundation (HPDF). This could provide a framework to integrate health promotion and social development into all government and civil society programmes. On priority issues, the HPDF would mobilise resources, allocate funding, develop capacity, and monitor and evaluate health promotion and development work. Emphasis would be on reducing the effects of poverty, inequity and unequal development on disease rates and wellbeing. The HPDF could also decrease the burden on the proposed National Health Insurance (NHI) system. We reflect on such foundations in other countries, and propose a structure for South Africa's HPDF and a dedicated funding stream to support its activities. In particular, an additional 2% levy on alcohol and tobacco products is proposed to be utilised to fund the HPDF.

OBJECTIF: Mettre au point un modèle permettant d'identifier les zones à haut risque d'épidémies sporadiques de rougeole, sur la base d'une analyse des facteurs associés à une épidémie nationale en Afrique du Sud, entre 2009 et 2011. MÉTHODES: Les données sur les cas survenus avant et pendant l'épidémie nationale ont été obtenues auprès du programme sud-africain de surveillance de la rougeole, et les données sur la vaccination contre la rougeole et la taille de la population auprès du système d'informations sanitaires des districts. Un modèle hiérarchique bayésien de Poisson a été utilisé pour étudier l'association entre le risque de rougeole chez les nourrissons dans un district et la couverture vaccinale pour la première dose, la densité de population, la prévalence sous-jacente de l'infection par le virus de l'immunodéficience humaine (VIH) et l'échec attendu de la séroconversion. Les projections du modèle ont été utilisées pour identifier les nouvelles zones à haut risque en 2012. RÉSULTAT: Un schéma spatial clair des zones à haut risque a été observé, avec de nombreuses zones interconnectées (c'est-à-dire voisines). Un risque accru d'épidémie de rougeole a été significativement associé à la constitution préalable d'une population vulnérable ainsi qu'à la densité de population. Le risque était aussi élevé lorsque plus de 20% des nourrissons dans une zone fortement peuplée n'avaient pas reçu une première dose du vaccin. Le modèle a été en mesure d'identifier les zones à haut risque d'épidémie de rougeole en 2012, ainsi que là où des mesures préventives supplémentaires pourraient être prises. CONCLUSION: L'épidémie de rougeole en Afrique du Sud a été associée à la constitution d'une population vulnérable (en raison d'une couverture vaccinale médiocre), à la prévalence élevée de l'infection par le VIH et à une forte densité de population. Le modèle prédictif développé pourrait être appliqué à d'autres contextes sensibles aux épidémies sporadiques de rougeole et à d'autres maladies qui peuvent être prévenues par la vaccination.

OBJECTIVE: To develop a model for identifying areas at high risk for sporadic measles outbreaks based on an analysis of factors associated with a national outbreak in South Africa between 2009 and 2011. METHODS: Data on cases occurring before and during the national outbreak were obtained from the South African measles surveillance programme, and data on measles immunization and population size, from the District Health Information System. A Bayesian hierarchical Poisson model was used to investigate the association between the risk of measles in infants in a district and first-dose vaccination coverage, population density, background prevalence of human immunodeficiency virus (HIV) infection and expected failure of seroconversion. Model projections were used to identify emerging high-risk areas in 2012. FINDINGS: A clear spatial pattern of high-risk areas was noted, with many interconnected (i.e. neighbouring) areas. An increased risk of measles outbreak was significantly associated with both the preceding build-up of a susceptible population and population density. The risk was also elevated when more than 20% of infants in a populous area had missed a first vaccine dose. The model was able to identify areas at high risk of experiencing a measles outbreak in 2012 and where additional preventive measures could be undertaken. CONCLUSION: The South African measles outbreak was associated with the build-up of a susceptible population (owing to poor vaccine coverage), high prevalence of HIV infection and high population density. The predictive model developed could be applied to other settings susceptible to sporadic outbreaks of measles and other vaccine-preventable diseases.

OBJETIVO: Desarrollar un modelo para identificar las áreas con riesgo alto de sufrir brotes esporádicos de sarampión en base a un análisis de los factores asociados a un brote nacional en Sudáfrica entre los años 2009 y 2011. MÉTODOS: Los datos de los casos ocurridos antes y durante el brote nacional se obtuvieron del programa de vigilancia del sarampión de Sudáfrica, y la información acerca de la vacunación contra el sarampión y el tamaño de la población, del sistema de información sanitaria por distritos. Se empleó un modelo de Poisson jerárquico bayesiano para investigar la relación entre el riesgo de sarampión en niños de un distrito con la cobertura de la primera dosis de la vacuna, la densidad de población, el historial de prevalencia de la infección por el virus de la inmunodeficiencia humana (VIH) y el fracaso previsto de la seroconversión. Las proyecciones del modelo se utilizaron para identificar áreas de alto riesgo nuevas en 2012. RESULTADOS: Se observó un patrón espacial claro de las áreas de alto riesgo con muchas zonas conectadas (esto es, colindantes). El riesgo superior de sufrir un brote de sarampión se asoció de modo significativo tanto con el crecimiento previo de un grupo de población vulnerable como con la densidad de población, y también fue elevado cuando más del 20% de los niños en un área populosa no había recibido la primera dosis de la vacuna. El modelo fue capaz de identificar las áreas con riesgo alto de sufrir un brote de sarampión en 2012 y donde podrían emprenderse medidas de prevención adicionales. CONCLUSIÓN: El brote de sarampión en Sudáfrica estuvo asociado con el aumento de un grupo de población vulnerable (debido a una cobertura de vacunación insuficiente), una prevalencia elevada de la infección por VIH y una densidad de población alta. El modelo predictivo desarrollado podría aplicarse a otros lugares susceptibles de sufrir brotes esporádicos de sarampión y otras enfermedades inmunoprevenibles.
