What, Where, and How to Collect Real-World Data and Generate Real-World Evidence to Support Drug Reimbursement Decision-Making in Asia: A reflection Into the Past and A Way Forward

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.

Real-world evidence of characteristics and factors influencing herbal medicine use for weight loss in adults

Background

Obesity imposes a significant socioeconomic burden owing to its high prevalence. In response to the adverse outcomes associated with conventional pharmacotherapy and the challenges of low adherence to lifestyle interventions, herbal medicine has surfaced as an actively utilized approach for weight loss. Therefore, this study aimed to analyze the characteristics and influencing factors of herbal medicine users for weight loss in adults.

Methods

Overall, 22,080 participants were included based on data from the Korea National Health and Nutrition Examination Survey from 2010 to 2019. Simple logistic regression analyses were used to derive the associations between herbal medicine use for weight loss and individual characteristics. Three models were constructed utilizing multiple logistic regression analyses to assess the associations between herbal medicine use for weight loss and the combined characteristics of predisposing, enabling, and need factors according to Andersen's model.

Results

In the full adjustment model, women, younger adults, those with higher incomes, and individuals reporting higher levels of perceived stress were more prone to use herbal medicine for weight loss in the past year. Adults who identified body image as being fat/very fat, those who consumed alcohol, and those classified as severely obese by body mass index were also more prone to use herbal medicine for weight loss. In particular, adults with a higher rate and amount of weight loss in the past year were more likely to use herbal medicine for weight loss compared to those experiencing weight gain/no changes/loss of 0-3 kg.

Conclusion

Our study was the first to derive the characteristics and influencing factors of herbal medicine users for weight loss among adults. These findings hold significant promise for informing future research endeavors and policy decision-making for effective resource distribution for obesity treatment.

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.

An operationalization framework for lifecycle health technology assessment: a Health Technology Assessment International Global Policy Forum Task Force report

Operationalization guidance is needed to support health technology assessment (HTA) bodies considering implementing lifecycle HTA (LC-HTA) approaches. The 2022 Health Technology Assessment International (HTAi) Global Policy Forum (GPF) established a Task Force to develop a position paper on LC-HTA. In its first paper, the Task Force established a definition and framework for LC-HTA in order to tailor it to specific decision problems. This second paper focused on the provision of practical operational guidance to implement LC-HTA. Detailed descriptions of the three LC-HTA operational steps are provided (defining the decision problem, sequencing of HTA activities, and developing optimization criteria) and accompanied by worked examples and an operationalization checklist with 20 different questions for HTA bodies to consider when developing an LC-HTA approach. The questions were designed to be applicable across different types of HTA and scenarios, and require adaptation to local jurisdictions, remits, and context.

The Critical Intersect of Regulations, Health Technology Assessment, and Drug Safety Assessments

Health technology assessment (HTA) is a multidisciplinary process that determines the value of health technology at different points in its lifecycle. Safety issues have become more important since regulatory authorities are increasingly adopting flexible standards, processes, and evidentiary requirements for drug approval. In this article, we compared the different role of regulatory authorities and HTA agencies. Additionally, the experience of regulatory-HTA collaboration for assessment and/or decision-making on safety issues in the lifecycle of a health technology is illustrated, including olmesartan (angiotensin II receptor antagonist) and the direct-acting hepatitis C virus (HCV) antiviral agents. Post-licensing data can be derived from various sources such as electronic health records, medical claims, drug and disease registries, post-authorization safety studies (PASS) or post-authorization safety efficacy studies (PAES), periodic benefit-risk assessment reports, as well as HTA reassessment reports, which incorporate utilization information from patients in a real-world setting and provide crucial evidence for various purposes. With the ongoing accumulation of safety and efficacy information during post-regulatory approval, a standardized process for continuous data collection and active reassessment of risk and benefit becomes crucial for managing the lifecycle of health technologies. In order to define evidence requirements clearly, reduce uncertainty, and minimize delays in HTA approval, early engagement and collaboration of HTA agencies in the regulatory review processes have become more common. However, there is currently limited interaction and collaboration between regulatory authorities and HTA agencies. This article aims to identify the challenges faced by regulators and HTA agencies today, emphasizing the significance of conducting regulatory reviews and health technology assessments throughout a technology's lifecycle, underlining the value of utilizing real-world data and evidence, and emphasizing the necessity of enhancing collaboration between regulatory authorities and HTA agencies, all within the overarching context of drug safety.

Fifteen Lessons from Fifteen Years of the Health Intervention and Technology Assessment Program in Thailand

The Health Intervention and Technology Assessment Program (HITAP) was established in 2007. This article highlights 15 lessons from over 15 years of experience, noting five achievements about what HITAP has done well, five areas that it is currently working on, and five aims for work in the future. HITAP built capacity for HTA and linked research to policy and practice in Thailand. With collaborators from academic and policy spheres, HITAP has mobilized regional and global support, and developed global public goods to enhance the field of HTA. HITAP's semi-autonomous structure has facilitated these changes, though they have not been without their challenges. HITAP aims to continue its work on HTA for public health interventions and disinvestments, effectively engaging with stakeholders and strategically managing its human resources. Moving forward, HITAP will develop and update global public goods on HTA, work on emerging topics such as early HTA, address issues in digital health, real-world evidence and equity, support HTA development globally, particularly in low-income settings, and seek to engage more effectively with the public. HITAP seeks to learn from its experience and invest in the areas identified so that it can grow sustainably. Its journey may be relevant to other countries and institutions that are interested in developing HTA programs.
