Strengthening health technology assessment systems in the global south: a comparative analysis of the HTA journeys of China, India and South Africa.

BACKGROUND: Resource allocation in health is universally challenging, but especially so in resource-constrained contexts in the Global South. Pursuing a strategy of evidence-based decision-making and using tools such as Health Technology Assessment (HTA), can help address issues relating to both affordability and equity when allocating resources. Three BRICS and Global South countries, China, India and South Africa have committed to strengthening HTA capacity and developing their domestic HTA systems, with the goal of getting evidence translated into policy. Through assessing and comparing the HTA journey of each country it may be possible to identify common problems and shareable insights. OBJECTIVES: This collaborative paper aimed to share knowledge on strengthening HTA systems to enable enhanced evidence-based decision-making in the Global South by: Identifying common barriers and enablers in three BRICS countries in the Global South; and Exploring how South-South collaboration can strengthen HTA capacity and utilisation for better healthcare decision-making. METHODS: A descriptive and explorative comparative analysis was conducted comprising a Within-Case analysis to produce a narrative of the HTA journey in each country and an Across-Case analysis to explore both knowledge that could be shared and any potential knowledge gaps. RESULTS: Analyses revealed that China, India and South Africa share many barriers to strengthening and developing HTA systems such as: (1) Minimal HTA expertise; (2) Weak health data infrastructure; (3) Rising healthcare costs; (4) Fragmented healthcare systems; and (5) Significant growth in non-communicable diseases. Stakeholder engagement and institutionalisation of HTA were identified as two conducive factors for strengthening HTA systems. CONCLUSION: China, India and South Africa have all committed to establishing robust HTA systems to inform evidence-based priority setting and have experienced similar challenges. Engagement among countries of the Global South can provide a supportive platform to share knowledge that is more applicable and pragmatic

Projecting the fiscal impact of South Africa’s contraceptive needs: Scaling up family planning post 2020

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.

South African clinical practice guidelines: A landscape analysis

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.

Cost-Effectiveness of Docetaxel and Paclitaxel for Adjuvant Treatment of Early Breast Cancer: Adaptation of a Model-Based Economic Evaluation From the United Kingdom to South Africa

Objectives Transferability of economic evaluations to low- and middle-income countries through adaptation of models is important; however, several methodological and practical challenges remain. Given its significant costs and the quality-of-life burden to patients, adjuvant treatment of early breast cancer was identified as a priority intervention by the South African National Department of Health. This study assessed the cost-effectiveness of docetaxel and paclitaxel-containing chemotherapy regimens (taxanes) compared with standard (non-taxane) treatments. Methods A cost-utility analysis was undertaken based on a UK 6-health-state Markov model adapted for South Africa using the Mullins checklist. The analysis assumed a 35-year time horizon. The model was populated with clinical effectiveness data (hazard ratios, recurrence rates, and adverse events) using direct comparisons from clinical trials. Resource use patterns and unit costs for estimating cost parameters (drugs, diagnostics, consumables, personnel) were obtained from South Africa. Uncertainty was assessed using probabilistic and deterministic sensitivity analyses. Results The incremental cost per patient for the docetaxel regimen compared with standard treatment was R6774. The incremental quality-adjusted life years (QALYs) were 0.24, generating an incremental cost-effectiveness ratio of R28430 per QALY. The cost of the paclitaxel regimen compared with standard treatment was estimated as −R578 and −R1512, producing an additional 0.03 and 0.025 QALYs, based on 2 trials. Paclitaxel, therefore, appears to be a dominant intervention. The base case results were robust to all sensitivity analyses. Conclusions Based on the adapted model, docetaxel and paclitaxel are predicted to be cost-effective as adjuvant treatment for early breast cancer in South Africa
