A landscape analysis of health technology assessment capacity in the Association of South-East Asian Nations region

Bridging Real-World Data Gaps: Connecting Dots Across 10 Asian Countries

The economic trend and the health care landscape are rapidly evolving across Asia. Effective real-world data (RWD) for regulatory and clinical decision-making is a crucial milestone associated with this evolution. This necessitates a critical evaluation of RWD generation within distinct nations for the use of various RWD warehouses in the generation of real-world evidence (RWE). In this article, we outline the RWD generation trends for 2 contrasting nation archetypes: "Solo Scholars"-nations with relatively self-sufficient RWD research systems-and "Global Collaborators"-countries largely reliant on international infrastructures for RWD generation. The key trends and patterns in RWD generation, country-specific insights into the predominant databases used in each country to produce RWE, and insights into the broader landscape of RWD database use across these countries are discussed. Conclusively, the data point out the heterogeneous nature of RWD generation practices across 10 different Asian nations and advocate for strategic enhancements in data harmonization. The evidence highlights the imperative for improved database integration and the establishment of standardized protocols and infrastructure for leveraging electronic medical records (EMR) in streamlining RWD acquisition. The clinical data analysis and reporting system of Hong Kong is an excellent example of a successful EMR system that showcases the capacity of integrated robust EMR platforms to consolidate and produce diverse RWE. This, in turn, can potentially reduce the necessity for reliance on numerous condition-specific local and global registries or limited and largely unavailable medical insurance or claims databases in most Asian nations. Linking health technology assessment processes with open data initiatives such as the Observational Medical Outcomes Partnership Common Data Model and the Observational Health Data Sciences and Informatics could enable the leveraging of global data resources to inform local decision-making. Advancing such initiatives is crucial for reinforcing health care frameworks in resource-limited settings and advancing toward cohesive, evidence-driven health care policy and improved patient outcomes in the region.

Building an effective medicines optimisation model: a health system approach

This commentary narrates on the building of an effective and innovative medicines optimisation model. It discusses the essential features, emphasizes the need, and considers the strong health and pharmacy system as a prerequisite before such a model could be built. The paper argues that it is important to strengthen the health system before the elements of pharmaceutical care and medicine optimisation can take shape. It discusses the discourse and interplay between medicine use and medicine access research. The other important elements to include are the "selection of medicines by health technology assessment", "economic evaluation of pharmacy services", "pharmacists' remuneration by the government", "Health system strengthening status", "quality use of generic medicines programmes", "rationale prescribing", "access to medicines and medicines pricing", "medicines advertising" and the "state of pharmacy practice and the development of the pharmacist's role". A set of different high-, middle- and low-income countries are used to provide examples of the status of the health system and the subsequent development of pharmacy practice and medicines optimisation. The countries include the UK, Australia, New Zealand, Pakistan, Türkiye, Malaysia, India, and Pakistan.

Integrated Real-World Data Warehouses Across 7 Evolving Asian Health Care Systems: Scoping Review

BACKGROUND

Asia consists of diverse nations with extremely variable health care systems. Integrated real-world data (RWD) research warehouses provide vast interconnected data sets that uphold statistical rigor. Yet, their intricate details remain underexplored, restricting their broader applications.

OBJECTIVE

Building on our previous research that analyzed integrated RWD warehouses in India, Thailand, and Taiwan, this study extends the research to 7 distinct health care systems: Hong Kong, Indonesia, Malaysia, Pakistan, the Philippines, Singapore, and Vietnam. We aimed to map the evolving landscape of RWD, preferences for methodologies, and database use and archetype the health systems based on existing intrinsic capability for RWD generation.

METHODS

A systematic scoping review methodology was used, centering on contemporary English literature on PubMed (search date: May 9, 2023). Rigorous screening as defined by eligibility criteria identified RWD studies from multiple health care facilities in at least 1 of the 7 target Asian nations. Point estimates and their associated errors were determined for the data collected from eligible studies.

RESULTS

Of the 1483 real-world evidence citations identified on May 9, 2023, a total of 369 (24.9%) fulfilled the requirements for data extraction and subsequent analysis. Singapore, Hong Kong, and Malaysia contributed to ≥100 publications, with each country marked by a higher proportion of single-country studies at 51% (80/157), 66.2% (86/130), and 50% (50/100), respectively, and were classified as solo scholars. Indonesia, Pakistan, Vietnam, and the Philippines had fewer publications and a higher proportion of cross-country collaboration studies (CCCSs) at 79% (26/33), 58% (18/31), 74% (20/27), and 86% (19/22), respectively, and were classified as global collaborators. Collaboration with countries outside the 7 target nations appeared in 84.2% to 97.7% of the CCCSs of each nation. Among target nations, Singapore and Malaysia emerged as preferred research partners for other nations. From 2018 to 2023, most nations showed an increasing trend in study numbers, with Vietnam (24.5%) and Pakistan (21.2%) leading the growth; the only exception was the Philippines, which declined by -14.5%. Clinical registry databases were predominant across all CCCSs from every target nation. For single-country studies, Indonesia, Malaysia, and the Philippines favored clinical registries; Singapore had a balanced use of clinical registries and electronic medical or health records, whereas Hong Kong, Pakistan, and Vietnam leaned toward electronic medical or health records. Overall, 89.9% (310/345) of the studies took >2 years from completion to publication.

CONCLUSIONS

The observed variations in contemporary RWD publications across the 7 nations in Asia exemplify distinct research landscapes across nations that are partially explained by their diverse economic, clinical, and research settings. Nevertheless, recognizing these variations is pivotal for fostering tailored, synergistic strategies that amplify RWD's potential in guiding future health care research and policy decisions.

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.

HTA capacity building in Asia: towards one goal

OBJECTIVES

The aim of the 2022 Health Technology Assessment International (HTAi) Asia Policy Forum (APF) was to discuss experiences and challenges around health technology assessment (HTA) capacity building for both HTA agencies and companies in the Asia region and to identify possible solutions as part of a capacity building roadmap.

METHODS

Discussions during the 2022 APF, informed by a pre-meeting survey of HTA agencies and industry attendees from the region, form the basis of this paper.

RESULTS

HTA is an essential element of priority-setting in healthcare; however, the scarcity of skilled technical HTA practitioners is a rate-limiting step in the conduct of HTA. The lack of investment in HTA and the political will to mandate the use of HTA in decision-making may be due to a lack of understanding of the value of the HTA process, and how HTA is interpreted and used in the healthcare decision-making process.

CONCLUSIONS

Increased demand for HTA is created when the value of HTA is recognized. HTA capacity-building challenges may be mitigated by educating stakeholders, particularly policymakers, on the value of, and the need to invest in, HTA as a transparent process to ensure equitable access to health care for all. Investigating a means of funding and implementing an HTA intern program between agencies, in partnership with industry, to facilitate a supportive environment to foster HTA skills and knowledge, build capacity or strengthen existing capacity should be a priority.

Health economic evaluations for Indonesia: a systematic review assessing evidence quality and adherence to the Indonesian Health Technology Assessment (HTA) Guideline

Background

The Government of Indonesia implemented health technology assessment (HTA) to ensure quality and cost control in the National Health Insurance Program (Jaminan Kesehatan Nasional/JKN). The current aim of the study was to improve the usefulness of future economic evaluation for resource allocation by appraising current methodology, reporting, and source of evidence quality of studies.

Methods

The inclusion and exclusion criteria were applied to search for relevant studies using a systematic review. The methodology and reporting adherence were appraised according to Indonesia's HTA Guideline issued in 2017. The differences in adherence before and after the guideline dissemination were compared using Chi-square and Fisher's exact tests for methodology adherence wherever appropriate, and the Mann-Whitney test for reporting adherence. The source of evidence quality was assessed using evidence hierarchy. Two scenarios of the study start date and the guideline dissemination period were tested using sensitivity analyses.

Findings

Eighty-four studies were obtained from PubMed, Embase, Ovid, and two local journals. Only two articles cited the guideline. No statistically significant difference (P > 0.05) was found between the pre-dissemination and post-dissemination period with respect to methodology adherence, except for outcome choice. Studies during the post-dissemination period showed a higher score for reporting which was statistically significant (P = 0.01). However, the sensitivity analyses revealed no statistically significant difference (P > 0.05) in methodology (except for modelling type, P = 0.03) and reporting adherence between the two periods.

Interpretation

The guideline did not impact the methodology and reporting standard used in the included studies. Recommendations were provided to improve the usefulness of economic evaluations for Indonesia.

The role of Iran's context for the development of health technology assessment: challenges and solutions

Health technology assessment (HTA) is a comprehensive and structured evaluation that aims to analyze the potential impacts of health technologies, including medical devices, diagnostic tools, pharmaceuticals, and public health interventions. Its purpose is to provide policymakers with evidence-based information to inform decisions related to the utilization and implementation of these technologies. HTA allows for the comparison of various scenarios related to a technology across a wide range of factors. This can aid in the creation of an essential drug list and health benefits package that is tailored to the actual needs of the community within a given healthcare system. In the present paper, we review the role of Iran's context for the development of HTA, in terms of challenges and solutions.

How Least Developed to Lower-Middle Income Countries Use Health Technology Assessment: A Scoping Review

Health Technology Assessment (HTA) is a multidisciplinary tool to inform healthcare decision-making. HTA has been implemented in high-income countries (HIC) for several decades but has only recently seen a growing investment in low- and middle-income countries. A scoping review was undertaken to define and compare the role of HTA in least developed and lower middle-income countries (LLMIC). MEDLINE and EMBASE databases were searched from January 2015 to August 2021. A matrix comprising categories on HTA objectives, methods, geographies, and partnerships was used for data extraction and synthesis to present our findings. The review identified 50 relevant articles. The matrix was populated and sub-divided into further categories as appropriate. We highlight topical aspects of HTA, including initiatives to overcome well-documented challenges around data and capacity development, and identify gaps in the research for consideration. Those areas we found to be under-studied or under-utilized included disinvestment, early HTA/implementation, system-level interventions, and cross-sectoral partnerships. We consider broad practical implications for decision-makers and researchers aiming to achieve greater interconnectedness between HTA and health systems and generate recommendations that LLMIC can use for HTA implementation. Whilst HIC may have led the way, LLMIC are increasingly beginning to develop HTA processes to assist in their healthcare decision-making. This review provides a forward-looking model that LLMIC can point to as a reference for their own implementation. We hope this can be seen as timely and useful contributions to optimize the impact of HTA in an era of investment and expansion and to encourage debate and implementation.

Developing a New Region-Specific Preference-Based Measure in East and Southeast Asia

OBJECTIVES

Almost all preference-based measures (PBMs) have been developed in Western countries, with none having been formulated in Asian countries. In this study, we construct a new generic PBM based on concept elicitation using interview surveys in East and Southeast Asian countries and qualitative analysis.

METHODS

This cross-sectional study included 225 adults recruited from 9 East and Southeast Asian countries or regions (Indonesia, Japan, Korea, mainland China, Malaysia, the Philippines, Singapore, Taiwan, and Thailand). Trained interviewers conducted semistructured interviews with 25 participants from the general population of each country/region. Qualitative data were analyzed using a content analysis approach. The selection of items was determined based on interview surveys and team member discussions. The description of items was considered based on a detailed qualitative analysis of the interview survey.

RESULTS

A new region-specific PBM-the Asia PBM 7 dimensions instrument-was designed. It reflects East and Southeast Asian values and comprises 7 items: pain, mental health, energy, mobility, work/school, interpersonal interactions, and burden to others.

CONCLUSIONS

The new region-specific instrument is one of the first PBMs developed in the context of non-Western countries. The Asia PBM 7 dimensions contains 7 items that address the core concepts of health-related quality of life that are deemed important based on East and Southeast Asian health concepts.

Redefining Health Technology Assessment: A Comment on "The New Definition of Health Technology Assessment: A Milestone in International Collaboration"

A new definition of health technology assessment (HTA), developed by an International Joint Task Group claims to be a "milestone," "an historic achievement," and "a cornerstone reference"-claims that we think to be unjustified. We too favor clear definitions, especially when confusion abounds. However, the Task Group seems to have developed a definition without the help of usual conventions regarding definitions and, in our view, through an ill-described process. A definition ought to differentiate the entity defined from other entities. This one fails to do so. It states traits that are true of HTA (e.g., that is interdisciplinary) but HTA is not alone in this. There are other concerns: examples of HTA's use are embodied in the definition, precluding other uses; the adjectives used, although generally true of HTA, are not differentiating features; and attributing to HTA specific purposes, thereby excluding other purposes. We have sympathy for these purposes but cannot consider them HTA's only purposes or even, its main purpose. A newcomer to HTA, on reading this definition, will have no idea of HTA's true potential. These numerous failings, we feel, send all the wrong signals, and could ultimately weaken, rather than strengthen perceptions of HTA's legitimacy and objectivity. The production of a good definition remains, therefore, a work in progress.

Cost-Effectiveness of Population Screening Programs for Cardiovascular Diseases and Diabetes in Low- and Middle-Income Countries: A Systematic Review

Almost all low- and middle-income countries (LMICs) have instated a program to control and manage non-communicable diseases (NCDs). Population screening is an integral component of this strategy and requires a substantial chunk of investment. Therefore, testing the screening program for economic along with clinical effectiveness is essential. There is significant proof of the benefits of incorporating economic evidence in health decision-making globally, although evidence from LMICs in NCD prevention is scanty. This systematic review aims to consolidate and synthesize economic evidence of screening programs for cardiovascular diseases (CVD) and diabetes from LMICs. The study protocol is registered on PROSPERO (CRD42021275806). The review includes articles from English and Chinese languages. An initial search retrieved a total of 2,644 potentially relevant publications. Finally, 15 articles (13 English and 2 Chinese reports) were included and scrutinized in detail. We found 6 economic evaluations of interventions targeting cardiovascular diseases, 5 evaluations of diabetes interventions, and 4 were combined interventions, i.e., screening of diabetes and cardiovascular diseases. The study showcases numerous innovative screening programs that have been piloted, such as using mobile technology for screening, integrating non-communicable disease screening with existing communicable disease screening programs, and using community health workers for screening. Our review reveals that context is of utmost importance while considering any intervention, i.e., depending on the available resources, cost-effectiveness may vary—screening programs can be made universal or targeted just for the high-risk population.

HTA Training for Healthcare Professionals: International Overview of Initiatives Provided by HTA Agencies and Organizations

Background

Health Technology Assessment (HTA) is a multidisciplinary process that synthesizes, with a systematic, transparent, impartial and robust methodological approach, the main information on the medical, economic, ethical and social implications of the use and dissemination of a health technology. Its aim is to support decision-makers in identifying safe, effective, patient-centered and best-value health policies, in order to promote an equitable, efficient, and high-quality health system. Given the continued application of innovative technologies into clinical practice, healthcare professionals need to be able to adequately evaluate these technologies using evidence-based approaches such as HTA. Therefore, the implementation of training in HTA is crucial. The aim of this study was to investigate existing HTA training initiatives for healthcare professionals provided by international HTA agencies and organizations around the world.

Methods

From March to November 2020, the websites of HTA agencies and organizations belonging to the European network for HTA (EUnetHTA) and to the International Network of Agencies for HTA (INAHTA), and the website of the HTA International (HTAi), were explored for identifying the HTA training initiatives directed to healthcare professionals. In addition, we screened the training initiatives proposed at European level by EUnetHTA as part of its Joint Actions and conducted in collaboration with its public-private partners. Specific keywords were searched in English and adapted to French, Portuguese, Spanish, Italian and German. Data extraction of the retrieved training initiatives was conducted from November 2020 to February 2021 and considered the following information: agency, country, website, coordinator, type of initiative, target, topic, main contents, and language.

Results

Out of 124 agencies/organizations/EUnetHTA public-private partners screened, only 21 provided training initiatives for healthcare professionals. A total of 55 training initiatives were analyzed, 85.5% of which were delivered at the European level and 14.5% at the international level. The countries with a greater number of courses were: Austria, Argentina, Spain, Portugal, and the United Kingdom. Twenty-one training initiatives focused on HTA application and methodology while 34 on specific HTA domains, particularly on the economic one. The technologies covered were mainly drugs.

Conclusions

Our study revealed a limited number of HTA training programs targeting healthcare professionals. HTA supports the decision-making processes concerning the use and application of health technologies with scientific evidence. Indeed, training of healthcare professionals in this field should be a key driver in implementing evidence-based healthcare choices and through rigorous methodological approaches such as HTA, in order to ensure proper health governance and value-based application of technological innovations in clinical practice. Therefore, capacity building of healthcare professionals in this area should be enhanced by using appropriate and effective training initiatives and educational strategies.

Evaluating the cost utility of racecadotril in addition to oral rehydration solution versus oral rehydration solution alone for children with acute watery diarrhea in four low middle-income countries: Egypt, Morocco, Philippines and Vietnam

AIM

To evaluate the cost utility of adjunct racecadotril and oral rehydration solution (R + ORS) versus oral rehydration solution (ORS) alone for the treatment of diarrhoea in children under five years with acute watery diarrhoea in four low-middle income countries.

METHOD

A cost utility model, previously developed and independently validated, has been adapted to Egypt, Morocco, Philippines and Vietnam. The model is a decision tree, cohort model programmed in Microsoft Excel. The model structure represents the country-specific clinical pathways. The target population is children under the age of five years presenting with symptoms of acute watery diarrhea to an outpatient clinic or general physician practice. A healthcare payer perspective has been analysed with the model parameterised with local data, where available. Most recent cost data has been used to inform the drug, outpatient and inpatient costs. Uncertainty has been explored with univariate deterministic sensitivity.

RESULTS

According to the base case models, R + ORS is dominant (cost-saving, more effective) versus ORS alone in Egypt, Morocco, Philippines and Vietnam. The incremental cost-effectiveness ratios in each country fall in the southeast (cost-saving, more effective) quadrant and represent a cost savings of -304,152 EGP per QALY gain in Egypt; -6,561 MAD per QALY gain in Morocco; -428,612 PHP per QALY gain in Philippines and -113,985,734 VND per QALY gain in Vietnam. Univariate deterministic sensitivity analysis shows that the three most influential parameters across all country adaptations are the utility of children without diarrhea; the utility of inpatient children with diarrhea and the cost of one night of inpatient care.

CONCLUSION

In keeping with similar findings in upper-middle and high-income countries, the cost utility of R + ORS versus ORS is favourable in low-middle income countries for the treatment of children under five with acute watery diarrhoea.

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.
