Adaptive health technology assessment to facilitate priority setting in low- and middle-income countries

Future support on evidence-informed priority setting and situational analysis of the potential role of Health Technology Assessment in Africa to support future pandemic preparedness and response: protocol for a scoping review

BACKGROUND

The COVID-19 pandemic has highlighted the importance of evidence-informed priority setting and situational analysis in pandemic preparedness and response. Health Technology Assessment (HTA) has been identified as an essential tool for evidence-informed decision-making in healthcare. However, the potential role of HTA in pandemic preparedness and response in Africa has yet to be explored. The objective of this scoping review is to ascertain the current understanding of the possible role of HTA in Africa to support future pandemic preparedness and response.

METHODS

We will conduct a scoping review of literature published between 2010 and 2024. Electronic databases like Embase, PubMed, Scopus, Web of Science, and Google Scholar will be utilized to perform the search. We will also search grey literature sources such as websites of relevant organizations and government agencies. The search will only include studies that were conducted in the English language. Two reviewers will evaluate the titles and abstracts of the publications independently to determine their eligibility using Covidence. Full-text articles will be reviewed for eligibility and data extraction. The data will be extracted using a standardized form. The extracted data will include information on the study design, objectives, methods, findings, and conclusions. The thematic analysis approach will guide the data analysis. Themes and sub-themes will be identified and reported. The review will be reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines.

DISCUSSION

This scoping review will identify the existing knowledge on the potential role of HTA in Africa to support future pandemic preparedness and response. The findings will aid in identifying deficiencies in knowledge and provide valuable insights for future study. Additionally, they will inform policy-makers and other stakeholders about the potential contribution of the Health Technology Assessment (HTA) in enhancing Africa's readiness and response to pandemics.

Global representativeness and impact of funding sources in cost-effectiveness research on systemic therapies for advanced breast cancer: A systematic review

BACKGROUND

Breast cancer (BC) is the most incident tumor and, consequently, any new intervention can potentially promote a considerable budget impact if incorporated. Cost-effectiveness (CE) studies assist in the decision-making process but may be influenced by the country's perspective of analysis and pharmaceutical industry funding.

METHODS

A systematic review of Medline, Scopus, and Web of Science from January 1st, 2012 to July 8th, 2022 was conducted to identify CE studies of tumor-targeted systemic-therapies for advanced BC. Articles without incremental cost-effectiveness ratio calculations were excluded. We extracted information on the country and class of drug studied, comparator type, authors' conflicts of interest (COI), pharmaceutical industry funding, and authors' conclusions.

RESULTS

71 studies comprising 204 CE assessments were included. The majority of studies were from the United States and Canada (44%), Asia (32%) and Europe (20%). Only 8% were from Latin America and none from Africa. 31% had pharmaceutical industry funding. The most studied drug classes were cyclin-dependent-kinase inhibitors (29%), anti-HER2 therapy (23%), anti-PD(L)1 (11%) and hormone therapy (11%). Overall, 34% of CE assessments had favorable conclusions. Pharmaceutical industry-funded articles had a higher proportion of at least one favorable conclusion (82% vs. 24%, p-value<0.001), European countries analyzed (45% vs. 9%, p-value = 0.003), and CE assessments with same class drug comparators (56% vs. 33%, p-value = 0.004).

CONCLUSIONS

Breast cancer CE literature scarcely represents low-and-middle-income countries' perspectives and is influenced by pharmaceutical industry funding which targets European countries', frequently utilizes comparisons within same-drug class, and is more likely to have favorable conclusions.

An overview of the perspectives used in health economic evaluations

The term 'perspective' in the context of economic evaluations and costing studies in healthcare refers to the viewpoint that an analyst has adopted to define the types of costs and outcomes to consider in their studies. However, there are currently notable variations in terms of methodological recommendations, definitions, and applications of different perspectives, depending on the objective or intended user of the study. This can make it a complex area for stakeholders when interpreting these studies. Consequently, there is a need for a comprehensive overview regarding the different types of perspectives employed in such analyses, along with the corresponding implications of their use. This is particularly important, in the context of low-and-middle-income countries (LMICs), where practical guidelines may be less well-established and infrastructure for conducting economic evaluations may be more limited. This article addresses this gap by summarising the main types of perspectives commonly found in the literature to a broad audience (namely the patient, payer, health care providers, healthcare sector, health system, and societal perspectives), providing their most established definitions and outlining the corresponding implications of their uses in health economic studies, with examples particularly from LMIC settings. We then discuss important considerations when selecting the perspective and present key arguments to consider when deciding whether the societal perspective should be used. We conclude that there is no one-size-fits-all answer to what perspective should be used and the perspective chosen will be influenced by the context, policymakers'/stakeholders' viewpoints, resource/data availability, and intended use of the analysis. Moving forward, considering the ongoing issues regarding the variation in terminology and practice in this area, we urge that more standardised definitions of the different perspectives and the boundaries between them are further developed to support future studies and guidelines, as well as to improve the interpretation and comparison of health economic evidence.

Rapid cost-effectiveness analysis: hemodialysis versus peritoneal dialysis for patients with acute kidney injury in Rwanda

BACKGROUND

To ensure the long-term sustainability of its Community-Based Health Insurance scheme, the Government of Rwanda is working on using Health Technology Assessment (HTA) to prioritize its resources for health. The objectives of the study were to rapidly assess (1) the cost-effectiveness and (2) the budget impact of providing PD versus HD for patients with acute kidney injury (AKI) in the tertiary care setting in Rwanda.

METHODS

A rapid cost-effectiveness analysis for patients with AKI was conducted to support prioritization. An 'adaptive' HTA approach was undertaken by adjusting the international Decision Support Initiative reference case for time and data constraints. Available local and international data were used to analyze the cost-effectiveness and budget impact of peritoneal dialysis (PD) compared with hemodialysis (HD) in the tertiary hospital setting.

RESULTS

The analysis found that HD was slightly more effective and slightly more expensive in the payer perspective for most patients with AKI (aged 15-49). HD appeared to be cost-effective when only comparing these two dialysis strategies with an incremental cost-effectiveness ratio of 378,174 Rwandan francs (RWF) or 367 United States dollars (US$), at a threshold of 0.5 × gross domestic product per capita (RWF 444,074 or US$431). Sensitivity analysis found that reducing the cost of HD kits would make HD even more cost-effective. Uncertainty regarding PD costs remains. Budget impact analysis demonstrated that reducing the cost of the biggest cost driver, HD kits, could produce significantly more savings in five years than switching to PD. Thus, price negotiations could significantly improve the efficiency of HD provision.

CONCLUSION

Dialysis is costly and covered by insurance in many countries for the financial protection of patients. This analysis enabled policymakers to make evidence-based decisions to improve the efficiency of dialysis provision.

Conducting a health technology assessment in the West Bank, occupied Palestinian territory: lessons from a feasibility project

OBJECTIVES

To achieve universal health coverage (UHC), countries must make difficult choices to optimize the use of scarce resources. There is a growing interest in using evidence-based priority setting processes, such as Health Technology Assessment (HTA), to inform these decisions. In 2020, the Palestinian Institute of Public Health (PNIPH) and the Norwegian Institute of Public Health (NIPH) initiated a pilot to test the feasibility of coproducing an HTA on breast cancer screening in the West Bank, occupied Palestinian Territory. Additionally, a secondary aim was to test whether using an adaptive HTA (aHTA) approach that searched and transferred published evidence syntheses could increase the speed of HTA production.

METHODS

The applied stepwise approach to the HTA is described in detail and can be summarized as defining a core team, topic selection, and prioritization; undertaking the HTA including adaptation using tools from the European Network for HTA (EUnetHTA) and stakeholder engagement; and concluding with dissemination.

RESULTS

The aHTA approach was faster but not as quick as anticipated, which is attributed to (i) the lack of availability of local evidence for contextualizing findings and (ii) the necessity to build trust between the team and stakeholders. Some delays followed from the COVID-19 pandemic, which showed the importance of good risk anticipation and mitigation. Lastly, other important lessons included the ability of virtual collaborations, the value of capacity strengthening initiatives within low- and middle-income countries (LMICs), and the need for early stakeholder engagement. Overall, the pilot was successfully completed.

CONCLUSION

This was the first HTA of its kind produced in Palestine, and despite the challenges, it shows that HTA analysis is feasible in this setting.

The Evolving Nature of Health Technology Assessment: A Critical Appraisal of NICE's New Methods Manual

OBJECTIVES

The National Institute for Health and Care Excellence (NICE) recently completed a review of its methods for health technology assessment, involving a 2-stage public consultation. We appraise proposed methodological changes and analyze key decisions.

METHODS

We categorize all changes proposed in the first consultation as "critical," "moderate" or "limited" updates, considering the importance of the topic and the degree of change or the level of reinforcement. Proposals were followed through the review process, for their inclusion, exclusion, or amendment in the second consultation and the new manual.

RESULTS

The end-of-life value modifier was replaced with a new "disease severity" modifier and other potential modifiers were rejected. The usefulness of a comprehensive evidence base was emphasized, clarifying when nonrandomized studies can be used, with further guidance on "real-world" evidence developed separately. A greater degree of uncertainty was accepted in circumstances when evidence generation raised challenges, in particular for children, rare diseases, and innovative technologies. For some topics, such as health inequality, discounting, unrelated healthcare costs, and value of information, significant changes were possibly warranted, but NICE decided not to make any revisions at present.

CONCLUSION

Most of the changes to NICE's health technology assessment methods are appropriate and modest in impact. Nevertheless, some decisions were not well justified and further research is needed on several topics, including investigation of societal preferences. Ultimately, NICE's role of protecting National Health Services resources for valuable interventions that can contribute toward improving overall population health must be safeguarded, without accepting weaker evidence.

Adaptive Health Technology Assessment: A Scoping Review of Methods

OBJECTIVES

Health technology assessment (HTA) is an established mechanism for explicit priority setting to support universal health coverage. However, full HTA requires significant time, data, and capacity for each intervention, which limits the number of decisions it can inform. Another approach systematically adapts full HTA methods by leveraging HTA evidence from other settings. We call this "adaptive" HTA (aHTA), although in settings where time is the main constraint, it is also called "rapid HTA."

METHODS

The objectives of this scoping review were to identify and map existing aHTA methods, and to assess their triggers, strengths, and weaknesses. This was done by searching HTA agencies' and networks' websites, and the published literature. Findings have been narratively synthesized.

RESULTS

This review identified 20 countries and 1 HTA network with aHTA methods in the Americas, Europe, Africa, and South-East Asia. These methods have been characterized into 5 types: rapid reviews, rapid cost-effectiveness analyses, rapid manufacturer submissions, transfers, and de facto HTA. Three characteristics "trigger" the use of aHTA instead of full HTA: urgency, certainty, and low budget impact. Sometimes, an iterative approach to selecting methods guides whether to do aHTA or full HTA. aHTA was found to be faster and more efficient, useful for decision makers, and to reduce duplication. Nevertheless, there is limited standardization, transparency, and measurement of uncertainty.

CONCLUSIONS

aHTA is used in many settings. It has potential to improve the efficiency of any priority-setting system, but needs to be better formalized to improve uptake, particularly for nascent HTA systems.

Validating the rigour of adaptive methods of economic evaluation

BACKGROUND

There has been a lot of debate on how to 'generalise' or 'translate' findings of economic evaluation (EE) or health technology assessment (HTA) to other country contexts. Researchers have used various adaptive HTA (aHTA) methods like model-adaptation, price-benchmarking, scorecard-approach, etc., for transferring evidence from one country to other. This study was undertaken to assess the degree of accuracy in results generated from aHTA approaches specifically for EE.

METHODS

By applying selected aHTA approaches, we adapted findings of globally published EE to Indian context. The first-step required identifying two interventions for which Indian EE (referred to as the 'Indian reference study') has been conducted. The next-step involved identification of globally published EE. The third-step required undertaking quality and transferability check. In the fourth step, outcomes of EE meeting transferability standards, were adapted using selected aHTA approaches. Lastly, adapted results were compared with findings of the Indian reference study.

RESULTS

The adapted cost estimates varied considerably, while adapted quality-adjusted life-years did not differ much, when matched with the Indian reference study. For intervention I (trastuzumab), adapted absolute costs were 11 and 6 times higher than the costs reported in the Indian reference study for control and intervention arms, respectively. Likewise, adapted incremental cost and incremental cost-effectiveness ratio (ICER) were around 3.5-8 times higher than the values reported in the Indian reference study. For intervention II (intensity-modulated radiation therapy), adapted absolute cost was 35% and 12% lower for the comparator and intervention arms, respectively, than the values reported in the Indian reference study. The mean incremental cost and ICER were 2.5 times and 1.5 times higher, respectively, than the Indian reference study values.

CONCLUSION

We conclude that findings from aHTA methods should be interpreted with caution. There is a need to develop more robust aHTA approaches for cost adjustment. aHTA may be used for 'topic prioritisation' within the overall HTA process, whereby interventions which are highly cost-ineffective, can be directly ruled out, thus saving time and resources for conducting full HTA for interventions that are not well studied or where evidence is inconclusive.

Cost-effectiveness analysis of different combination therapies for the treatment of chronic lymphocytic leukaemia in India

Background

Over the years, there has been introduction of newer drugs, like bendamustine and ibrutinib, for the management of chronic lymphocytic leukaemia (CLL). Though these drugs lead to better survival, they are also associated with higher cost. The existing evidence on cost effectiveness of these drugs is from high-income countries, which has limited generalisability for low-income and middle-income counties. Therefore, the present study was undertaken to assess the cost-effectiveness of three therapeutic regimens, chlorambucil plus prednisolone (CP), bendamustine plus rituximab (BR) and ibrutinib for CLL treatment in India.

Methods

A Markov model was developed for estimating lifetime costs and consequences in a hypothetical cohort of 1000 CLL patients following treatment with different therapeutic regimens. The analysis was performed based on a limited societal perspective, 3% discount rate and lifetime horizon. The clinical effectiveness of each regime in the form of progression-free survival and occurrence of adverse events were assessed from various randomised controlled trials. A structured comprehensive review of literature was undertaken for the identification of relevant trials. The data on utility values and out of pocket expenditure was obtained from primary data collected from 242 CLL patients across six large cancer hospitals in India.

Findings

As compared to the most affordable regimen comprising of CP as first-line followed by BR as second-line therapy, none of the other therapeutic regimens were cost-effective at one time per capita gross-domestic product of India. However, if the current price of either combination of BR and ibrutinib or even ibrutinib alone could be reduced by more than 80%, regimen comprising of BR as first-line therapy followed by second-line ibrutinib would become cost-effective.

Interpretation

At the current market prices, regimen comprising of CP as first-line followed by BR as second-line therapy is the most cost-effective strategy for CLL treatment in India.

Funding

Determinants of cancer drug pricing and how to overcome the cancer premium

The high and increasing prices of cancer drugs are a public health challenge. To disrupt the cancer premium and improve patient access to cancer drugs, different action steps are indicated: more transparency on the price determination process and actual prices, value-based pricing, and "price with evidence development."

Transferability of real-world data across borders for regulatory and health technology assessment decision-making

Recently, there has been increased consideration of real-world data (RWD) and real-world evidence (RWE) in regulatory and health technology assessment (HTA) decision-making. Due to challenges in identifying high-quality and relevant RWD sources, researchers and regulatory/HTA bodies may turn to RWD generated in locales outside of the locale of interest (referred to as "transferring RWD"). We therefore performed a review of stakeholder guidance as well as selected case studies to identify themes for researchers to consider when transferring RWD from one jurisdiction to another. Our review highlighted that there is limited consensus on defining decision-grade, transferred RWD; certain stakeholders have issued relevant guidance, but the recommendations are high-level and additional effort is needed to generate comprehensive guidance. Additionally, the case studies revealed that RWD transferability has not been a consistent concern for regulatory/HTA bodies and that more focus has been put on the evaluation of internal validity. To help develop transferability best practices (alongside internal validity best practices), we suggest that researchers address the following considerations in their justification for transferring RWD: treatment pathways, nature of the healthcare system, incidence/prevalence of indication, and patient demographics. We also recommend that RWD transferability should garner more attention as the use of imported RWD could open doors to high-quality data sources and potentially reduce methodological issues that often arise in the use of local RWD; we thus hope this review provides a foundation for further dialogue around the suitability and utility of transferred RWD in the regulatory/HTA decision-making space.

Institutionalizing health technology assessment in Egypt: Situational analysis and roadmap

Objective: To conduct a situational analysis with the aim to inform future health technology assessment efforts (HTA) in Egypt.

Introduction: The Egyptian government has set universal health coverage as a 2030 target. Several agencies have been created in the context of the ongoing healthcare reform. The Egyptian Authority for Unified Procurement, Medical Supply and the Management of Medical Technology (UPA) is one of them and was established to support strategic procurement using HTA.

Methods: Description of the development of HTA in Egypt supported by a literature search as part of a scoping exercise, and a stakeholder analysis and identification of HTA capacity survey, based on previous surveys, with relevant stakeholders conducted in 2022. This was followed by a stakeholder event where results were shared and further contextualized.

Results: The UPA is expected to evaluate the cost-effectiveness of health technologies and public health programs. The HTA process is being developed, focusing on the assessment of the value of new pharmaceuticals being introduced to the Egyptian market. A total of 16 participants responded on behalf of their organizations to the stakeholder analysis and identification of HTA capacity survey. More than 80% of the respondents were familiar with current efforts conducted by UPA and strongly support the implementation of HTA in Egypt. Transparency was highlighted as an important criterion. Over 90% of the respondents mentioned economic analyses as an HTA product being developed in Egypt, and medicines were the type of technology that stakeholders ranked as first in the rank of health technologies that need the output from HTA urgently. Capability building and training were highlighted as areas in which further support is required.

Conclusion: This study represents the first attempt to describe the current path for HTA in Egypt. There seems to be momentum in Egypt to proceed and advance with HTA institutionalization. It would be important that next steps are built on the skills and capabilities already in place in Egypt, ensure methods and processes are in place and up to date and involve the wider system in Egypt so stakeholders can appropriately contribute and participate in the HTA process.

How can health technology assessment support our response to public health emergencies?

Public health emergencies (PHEs), such as the COVID-19 crisis, are threats to global health and public order. We recommend that countries bolster their PHE responses by investing in health technology assessment (HTA), defined as a systematic process of gathering pertinent information on and evaluating health technologies from a medical, economic, social and ethical standpoint. We present examples of how HTA organizations in low- and middle-income countries have adapted to supporting PHE-related decisions during COVID-19 and describe the ways HTA can help the response to a PHE. In turn, we advocate for HTA capacity to be further developed globally and for increased institutional acceptance of these methods as a building block for preparedness and response to future PHEs. Finally, the long-term potential of HTA in strengthening health systems and embedding confidence and transparency into scientific policy should be recognized.

Considerations for transferability of health technology assessments: a scoping review of tools, methods, and practices

Health technology assessment (HTA) is commonly used to guide evidence-informed decisions to optimize resource use, prioritize policies, and support countries to achieve universal health coverage. Producing HTAs requires time, scientific expertise, and political commitment, but these are not available in all settings - especially in low- and middle-income countries (LMIC) where HTA processes may be less institutionalized. Transferring and adapting existing HTAs to local settings may offer a solution while reducing duplication efforts. This scoping review aims to provide an overview of tools, methods, approaches, and considerations which can aid HTA transfers. We systematically searched (from 2005 to 2020) six databases and, using predefined inclusion criteria, included twenty-two studies. Data extraction followed a structured process, while synthesis was more iterative. We identified a common approach for HTA transfers. It follows the de novo process of undertaking original HTAs, but with additional steps to assess relevance (applicability), quality, and transferability, as well as steps to adapt parameters where necessary. The EUnetHTA Adaptation Toolkit was the only tool that provided guidance for adapting multiple HTA domains. Other tools were specific to systematic reviews (n = 1) or economic evaluations (n = 12), where one provided guidance for systematic reviews of economic evaluations. Eight papers reported transferring an HTA, with only one transferring to an LMIC. Finally, we reported issues that may facilitate or hinder transferability. In conclusion, we identified fourteen transfer approaches in the form of guidance or checklists, but harmonized and pragmatic guidance for HTA transfers to suit settings with limited HTA capacity seems warranted.

Ensuring quality in contextualised cancer management guidelines for resource-constraint settings: using a systematic approach

To address the wide variation in access to cancer care in India requires strengthening of infrastructure, trained oncology workforce, and minimisation of out-of-pocket expenditures. However, even with major investments, it is unlikely to achieve the same level of infrastructure and expertise across the country. Therefore, a resource stratified approach driven by evidence-based and contextualised clinical guidelines is the need of the hour. The National Cancer Grid has been at the forefront of delivery of standardised cancer care through several of its initiatives, including the resource-stratified guidelines. Development of new guidelines is resource and time intensive, which may not be feasible and can delay the implementation. Adaptation of the existing standard guidelines using the transparent and well-documented methodology with involvement of all stakeholders can be one of the most reasonable pathways. However, the adaptation should be done keeping in mind the context, resource availability, budget impact, investment needed for implementation and acceptability by clinicians, patients, policymakers, and other stakeholders. The present paper provides the framework for systematically developing guidelines through adaptation and contextualisation. The process can be used for other health conditions in resource-constraint settings.

Challenges in the development of digital public health interventions and mapped solutions: Findings from a scoping review

Background

“Digital public health” has emerged from an interest in integrating digital technologies into public health. However, significant challenges which limit the scale and extent of this digital integration in various public health domains have been described. We summarized the literature about these challenges and identified strategies to overcome them.

Methods

We adopted Arksey and O’Malley's framework (2005) integrating adaptations by Levac et al. (2010). OVID Medline, Embase, Google Scholar, and 14 government and intergovernmental agency websites were searched using terms related to “digital” and “public health.” We included conceptual and explicit descriptions of digital technologies in public health published in English between 2000 and June 2020. We excluded primary research articles about digital health interventions. Data were extracted using a codebook created using the European Public Health Association's conceptual framework for digital public health.

Results and analysis

Overall, 163 publications were included from 6953 retrieved articles with the majority (64%, n = 105) published between 2015 and June 2020. Nontechnical challenges to digital integration in public health concerned ethics, policy and governance, health equity, resource gaps, and quality of evidence. Technical challenges included fragmented and unsustainable systems, lack of clear standards, unreliability of available data, infrastructure gaps, and workforce capacity gaps. Identified strategies included securing political commitment, intersectoral collaboration, economic investments, standardized ethical, legal, and regulatory frameworks, adaptive research and evaluation, health workforce capacity building, and transparent communication and public engagement.

Conclusion

Developing and implementing digital public health interventions requires efforts that leverage identified strategies to overcome diverse challenges encountered in integrating digital technologies in public health.

Comparison of the registration process of the medicines control authority of Zimbabwe with Australia, Canada, Singapore, and Switzerland: benchmarking best practices

BACKGROUND

Benchmarking regulatory systems of low- and middle-income countries with mature systems provides an opportunity to identify gaps, enhance review quality, and reduce registration timelines, thereby improving patients' access to medicines. The aim of this study was to compare the medicines registration process of the Medicines Control Authority of Zimbabwe (MCAZ) with the regulatory processes in Australia, Canada, Singapore, and Switzerland.

METHODS

A questionnaire that standardizes the review process, allowing key milestones, activities and practices of the five regulatory authorities was completed by a senior member of the divisions responsible for issuing marketing authorizations.

RESULTS

The MCAZ has far fewer resources than the regulatory authorities in the comparator countries, but employs three review models, which is in line with international best practice. The MCAZ registration process is similar to the comparator countries in key milestones monitored, but differs in the target timelines for these milestones. The MCAZ is comparable to the comparator authorities in implementing the majority of good review practices, although it significantly lags behind in transparency and communication.

CONCLUSION

This study identified the MCAZ strengths and opportunities for improvement, which if implemented, will enable the achievement of its vision to be a leading regulatory authority in Africa.

Avoiding health technology assessment: a global survey of reasons for not using health technology assessment in decision making

INTRODUCTION

Despite the documented benefits of using health technology assessments (HTA) to inform resource allocation in health care systems, HTA remains underused, especially in low- and middle-income countries. A survey of global health practitioners was conducted to reveal the top reasons ("excuses") that they had heard from colleagues, policymakers or other stakeholders for not using HTA in their settings.

METHODS

There were 193 respondents to the survey. Most responses were from individuals in research organisations (37%), ministries of health (27%) and other government agencies (14%). Participants came from Southeast Asia (40%), the Western Pacific (30%), Africa (15%), Europe (7%), the Americas (7%) and the Eastern Mediterranean region (2%).

RESULTS

The top five reasons encountered by respondents related to lack of data, lack of technical skills for HTA, the technocratic nature of the work, the lack of explicit decision rules and the perception that HTA puts a "price on life".

CONCLUSIONS

This study aimed to understand and address the top reasons for not using HTA. They fall into three categories: (1) misconceptions about HTA; (2) feasibility issues; and (3) values, attitudes and politics. Previous literature has shown that these reasons can be addressed when identified, and even imperfect HTA analyses can provide useful information to a decision-maker.

Health technology assessment in sub-Saharan Africa: a descriptive analysis and narrative synthesis

Background

Countries in Sub-Saharan Africa (SSA) are moving towards universal health coverage. The process of Health Technology Assessment (HTA) can support decisions relating to benefit package design and service coverage. HTA involves institutional cooperation with agreed methods and procedural standards. We systematically reviewed the literature on policies and capacity building to support HTA institutionalisation in SSA.

Methods

We systematically reviewed the literature by searching major databases (PubMed, Embase, etc.) until June 2019 using terms considering three aspects: HTA; health policy, decision making; and SSA. We quantitatively extracted and descriptively analysed content and conducted a narrative synthesis eliciting themes from the selected literature, which varied in study type and apporach.

Results

Half of the 49 papers identified were primary research studies and mostly qualitative. Five countries were represented in six of ten studies; South Africa, Ghana, Uganda, Cameroon, and Ethiopia. Half of first authors were from SSA. Most informants were policy makers. Five themes emerged: (1) use of HTA; (2) decision-making in HTA; (3) values and criteria for setting priority areas in HTA; (4) involving stakeholders in HTA; and (5) specific examples of progress in HTA in SSA. The first one was the main theme where there was little use of evidence and research in making policy. The awareness of HTA and economic evaluation was low, with inadequate expertise and a lack of local data and tools.

Conclusions

Despite growing interest in HTA in SSA countries, awareness remains low and HTA-related activities are uncoordinated and often disconnected from policy. Further training and skills development are needed, firmly linked to a strategy focusing on strengthening within-country partnerships, particularly among researchers and policy makers. The international community has an important role here by supporting policy- relevant technical assistance, highlighting that sustainable financing demands evidence-based processes for effective resource allocation, and catalysing knowledge-sharing opportunities among countries facing similar challenges.

Cost effectiveness of typhoid vaccination in India

INTRODUCTION

World Health Organization has prequalified the use of typhoid conjugate vaccine (TCV) in children over six months of age in typhoid endemic countries. We assessed the cost-effectiveness of introducing TCV separately for urban and rural areas of India.

METHODS

A decision analytic model was developed, using a societal perspective, to compare long-term costs and outcomes (3% discount rate) in a new-born cohort of 100,000 children immunized with or without TCV. Three vaccination scenarios were modelled, assuming the protective efficacy of TCV to last for 5, 10 and 15 years following immunization. Incidence of typhoid infection estimated under 'National Surveillance System for Enteric Fever' (NSSEFI)' was used. The prices of vaccine and cost of service delivery were included for vaccination arm. Both health system cost and out-of-pocket expenditures for treatment of typhoid illness and its complications was included.

RESULTS

TCV introduction in urban areas would result in prevention of 17% to 36% typhoid cases and deaths. With exclusion of indirect costs, the incremental cost per QALY gained was ₹ 151,346 (54,730-307,975), ₹ 61,710 (-5250 to 163,283) and ₹ 45,188 (-17,069 to 141,093) for scenario 1, 2 and 3 respectively. While, with inclusion of indirect costs, all 3 scenarios were cost saving. Further, in rural areas, TCV is estimated to reduce the typhoid cases and deaths by 19% to 36%, with ICER (incremental cost per QALY gained) ranging from ₹ 2340 (1316-4370) to ₹ 3574 (2057 - 6691) thousand (inclusive of indirect costs) among the 3 vaccination scenarios.

CONCLUSION

From a societal perspective, introduction of TCV is a cost saving strategy in urban India. Further, due to low incidence of typhoid infection, introduction of TCV is not cost-effective in rural settings of India.

Health Technology Assessment in High, Middle, and Low-income Countries: New Systematic and Interdisciplinary Approach For Sound Informed-policy Making: Research Protocole

Technological innovation has a significant role in improving health systems (HSs) and achieving universal health coverage (UHC). The World Health Organization (WHO) has declared resolutions on Health Technology Assessment (HTA) and other global organizations emphasized on HTA systems to achieve the Sustainable Development Goals (SDGs). HTA is a modern multidisciplinary decision-making framework linking knowledge and policymaking by assessing the medical, social, economic, organizational, and ethical effects, and/or impacts within health and social systems. The research significance lies in the growing need for HTA at these moments than ever as it is seen as an essential development approach to tackle the current global challenges and pandemics, particularly in developing countries. The research aims to comprehensively evaluate and understand HTA systems concerning the level of knowledge about HTA, current HTA structure, practices, application, capacity, gaps, and solutions. The project starts in January 2021 and ends in January 2022 and will be carried out in seven countries: Canada, Switzerland, Brazil, Lebanon, Jordan, Palestine, and Tanzania. A mixed-methods, quantitative and qualitative, along with a literature review will be applied. In each country, ten HTA-associated institutions will complete an adapted electronic survey, developed by the WHO, and ten key-informants selected purposively from the government, academia, NGOs, and private sectors to participate in ten individual in-depth interviews. One government representative from each country will participate in one expanded inter-country workshop. Excel, IBM Statistical Package for the Social Sciences (SPSS), and MAXQDA software programs will be used for data management and analysis. The research will form cutting-edge evidence not only for the seven countries, but also for the global, regional, and national endeavors with regards to opening a room for HTA best application and optimization. It will reveal lessons learned, determine gaps, and build a well-enabled and institutionalized HTA for better UHC, health systems, and multi-sectoral development.
