    BACKGROUND: Progress towards achieving Universal Health Coverage and institutionalizing healthcare priority setting through health technology assessment (HTA) in the Association of South-East Asian Nations (ASEAN) region varies considerably across countries because of differences in healthcare expenditure, political support, access to health information and technology infrastructure. To explore the status and capacity of HTA in the region, the ASEAN Secretariat requested for member countries to be surveyed to identify existing gaps and to propose solutions to help countries develop and streamline their priority-setting processes for improved healthcare decision-making.

    METHODS: A mixed survey questionnaire with open- and closed-ended questions relating to HTA governance, HTA infrastructure, supply and demand of HTA and global HTA networking opportunities in each country was administered electronically to representatives of HTA nodal agencies of all ASEAN members. In-person meetings or email correspondence were used to clarify or validate any unclear responses. Results were collated and presented quantitatively.

    RESULTS: Responses from eight out of ten member countries were analysed. The results illustrate that countries in the ASEAN region are at different stages of HTA institutionalization. While Malaysia, Singapore and Thailand have well-established processes and methods for priority setting through HTA, other countries, such as Cambodia, Indonesia, Lao PDR, Myanmar, the Philippines and Vietnam, have begun to develop HTA systems in their countries by establishing nodal agencies or conducting ad-hoc activities.

    DISCUSSION AND CONCLUSION: The study provides a general overview of the HTA landscape in ASEAN countries. Systematic efforts to mitigate the gaps between the demand and supply of HTA in each country are required while ensuring adequate participation from stakeholders so that decisions for resource allocation are made in a fair, legitimate and transparent manner and are relevant to each local context.

    This article describes a 1-week training course in health technology assessment (HTA) presented in Malaysia by the Ministry of Health in 1996. Malaysia established an HTA unit in the Ministry of Health in 1995 and a National Health Technology Assessment Program in 1996. The purpose of the course was to develop HTA knowledge and skills in Malaysia, since these are largely lacking. The course consisted of didactic sessions and group work. Didactic sessions covered the principles of HTA. Group work was for the purpose of developing practical skills, and was based on reports from HTA agencies, published articles, and candidates for assessment suggested by course participants. Course participants were a mix of physicians, nurses, hospital administrators, and Ministry of Health officials. Experiences in this course may be helpful to others who wish to organize training courses in developing countries.

    Patient and public involvement (PPI) in health technology assessment (HTA) is widely promoted to ensure that all health-related decisions are made after taking into consideration the viewpoints of important stakeholders. In Malaysia, patients or their representatives have been involved in the development of HTA and Clinical Practice Guidelines (CPG) since 2009 and their influences have been growing steadily over the years. This paper aimed to describe the journey, achievements, challenges, and future direction of the PPI throughout all stages of the development and implementation of HTA and CPG in Malaysia. Currently, in Malaysia, patients or their representatives are mainly involved during the initial development of HTA and CPG drafts as well as during the internal and external reviews. Additionally, they are also encouraged to be involved during the implementation of HTA and CPG recommendations. Although their involvement in this aspect has slowly increased over time, challenges remain in the form of limited representativeness of selected patients or carers, uncertainty on the level of patient involvement allowed during the HTA/CPG development processes, and limited health literacy, which affect their ability to contribute meaningfully throughout the processes. Continuous improvement in these processes is important as patients or their representatives play a pivotal role in ensuring transparency, accountability, and credibility throughout the HTA/CPG development and decision-making processes.

    The realization of Health Information Systems (HIS) requires rigorous evaluation that addresses technology, human and organization issues. Our review indicates that current evaluation methods evaluate different aspects of HIS and they can be improved upon. A new evaluation framework, human, organization and technology-fit (HOT-fit) was developed after having conducted a critical appraisal of the findings of existing HIS evaluation studies. HOT-fit builds on previous models of IS evaluation--in particular, the IS Success Model and the IT-Organization Fit Model. This paper introduces the new framework for HIS evaluation that incorporates comprehensive dimensions and measures of HIS and provides a technological, human and organizational fit.

    Wireless capsule endoscopy (WCE) is a promising technology for direct diagnosis of the entire small bowel to detect lethal diseases, including cancer and obscure gastrointestinal bleeding (OGIB). To improve the quality of diagnosis, some vital specifications of WCE such as image resolution, frame rate and working time need to be improved. Additionally, future multi-functioning robotic capsule endoscopy (RCE) units may utilize advanced features such as active system control over capsule motion, drug delivery systems, semi-surgical tools and biopsy. However, the inclusion of the above advanced features demands additional power that make conventional power source methods impractical. In this regards, wireless power transmission (WPT) system has received attention among researchers to overcome this problem. Systematic reviews on techniques of using WPT for WCE are limited, especially when involving the recent technological advancements. This paper aims to fill that gap by providing a systematic review with emphasis on the aspects related to the amount of transmitted power, the power transmission efficiency, the system stability and patient safety. It is noted that, thus far the development of WPT system for this WCE application is still in initial stage and there is room for improvements, especially involving system efficiency, stability, and the patient safety aspects.

    Objectives. The current health technology assessment used to evaluate respiratory inhalers is associated with limitations that have necessitated the development of an explicit formulary decision-making framework to ensure balance between the accessibility, value, and affordability of medicines. This study aimed to develop a multiple-criteria decision analysis (MCDA) framework, apply the framework to potential and currently listed respiratory inhalers in the Ministry of Health Medicines Formulary (MOHMF), and analyze the impacts of applying the outputs, from the perspective of listing and delisting medicines in the formulary. Methods. The overall methodology of the framework development adhered to the recommendations of the ISPOR MCDA Emerging Good Practices Task Force. The MCDA framework was developed using Microsoft Excel 2010 and involved all relevant stakeholders. The framework was then applied to 27 medicines, based on data gathered from the highest levels of available published evidence, pharmaceutical companies, and professional opinions. The performance scores were analyzed using the additive model. The end values were then deliberated by an expert committee. Results. A total of eight main criteria and seven subcriteria were determined by the stakeholders. The economic criterion was weighted at 30%. Among the noneconomic criteria, "patient suitability" was weighted the highest. Based on the MCDA outputs, the expert committee recommended one potential medicine (out of three; 33%) be added to the MOHMF and one existing medicine (out of 24; 4%) be removed/delisted from the MOHMF. The other existing medicines remained unchanged. Conclusions. Although this framework was useful for deciding to add new medicines to the formulary, it appears to be less functional and impactful for the removal/delisting existing medicines from the MOHMF. The generalizability of this conclusion to other formulations remains to be confirmed.

    OBJECTIVES: The aim of this study was to describe the historical development of the HTAsiaLink network, draw lessons for other similar initiatives globally, and to analyze key determinants of its success and challenges for its future development.

    METHODS: This study is based on the collective and direct experiences of the founding members of the HTAsiaLink Network. Data were collected from presentations they made at various international forums and additional information was reviewed. Data analysis was done using the framework developed by San Martin-Rodriguez et al.Results and Conclusions:HTAsiaLink is a network of health technology assessment (HTA) agencies in Asia established in 2011 with the aim of strengthening individual and institutional HTA capacity, reducing duplication and optimizing resources, transfer and sharing of HTA-related lessons among members, and beyond. During its 6 years, the network has expanded, initiating several capacity building activities and joint-research projects, raising awareness of the importance of HTA within the region and beyond, and gaining global recognition while establishing relationships with other global networks. The study identifies the determinants of success of the collaboration. The systemic factors include the favorable outlook toward HTA as an approach for healthcare priority setting in countries with UHC mandates. On organizational factors, the number of newly established HTA agencies in the region with similar needs for capacity building and peer-to-peer support was catalytic for the network development. The interactional aspects include ownership, trust, and team spirit among network members. The network, however, faces challenges notably, financial sustainability and management of the expanded network.

    OBJECTIVE: To describe the process and role of health technology assessment (HTA) in the context of drug policy in Malaysia.

    METHODS: We summarized the HTA process through review of documents and reports available in the public domain combined with the authors' experience.

    RESULTS: Health technology assessment plays an integral part in prioritizing treatment in public health facilities in Malaysia, particularly for the Ministry of Health Medicines Formulary (MOHMF). The MOHMF is the reference list of drugs allowed to be prescribed in the Ministry of Health (MOH) facilities. There are 2 organizations within the MOH that conduct HTA as their core activities, namely the Malaysian Health Technology Assessment Section and the Formulary Management Branch of Pharmacy Practice & Development Division. The assessment of pharmaceuticals for the purpose of listing medicines into the MOHMF is under the purview of the Formulary Management Branch. The evidence-based assessment focuses on safety, efficacy, effectiveness, and budget impact of the drug. Cost-effectiveness evidence is currently not mandatory but is of interest to the decision makers. The assessment outcomes are considered by the MOH Medicines List Review Panel for formulary decisions.

    CONCLUSIONS: Health technology assessment has supported formulary decisions in MOH. Evidence generation needs to progress beyond efficacy or effectiveness, safety, and budget impact to incorporate cost-effectiveness. Nevertheless, there are challenges to be met to achieve this. The impact of the HTA process is currently unknown and is yet to be evaluated formally.

    OBJECTIVES: The aim of this study was to provide a comprehensive overview of the evolution of health technology assessment (HTA) in Malaysia over the past decade.

    METHODS: We described the evolution of HTA program in Malaysia based on review of administrative data, publicly available information and quantitative description of impact evaluation.

    RESULTS: Health Technology Assessment HTA was formalized in Malaysia in 1995 as a central structure within the Ministry of Health, Malaysia in 1995. Expansion of activities demonstrated over the years including Horizon Scanning of health technologies and implementation of evidence-based Clinical Practice Guidelines. Improvement on the processes in terms of types of report, quality, monitoring, and impact evaluation as well as accessibility was also carried out. Examples of impact/influence of the reports have also been demonstrated.

    CONCLUSIONS: HTA program in Malaysia has evolved over the past decades. Its role in policy formulation and decision making of health technologies has become more significant over the years and is foreseen to be bigger in the future. As a trusted source of evidence, HTA in Malaysia will continue to strengthen the health system by advocating informed decision making and value-based medicine. As other countries in this region is trying to establish their own HTA processes and procedures, this review on the evolution of the HTA program in Malaysia might give some insights on developing a sustainable HTA program.

    Health technology assessment (HTA) has been continuously used for value-based healthcare decisions over the last decade. Healthcare databases represent an important source of information for HTA, which has seen a surge in use in Western countries. Although HTA agencies have been established in Asia-Pacific region, application and understanding of healthcare databases for HTA is rather limited. Thus, we reviewed existing databases to assess their potential for HTA in Thailand where HTA has been used officially and Japan where HTA is going to be officially introduced.

    Humidity measurement is one of the most significant issues in various areas of applications such as instrumentation, automated systems, agriculture, climatology and GIS. Numerous sorts of humidity sensors fabricated and developed for industrial and laboratory applications are reviewed and presented in this article. The survey frequently concentrates on the RH sensors based upon their organic and inorganic functional materials, e.g., porous ceramics (semiconductors), polymers, ceramic/polymer and electrolytes, as well as conduction mechanism and fabrication technologies. A significant aim of this review is to provide a distinct categorization pursuant to state of the art humidity sensor types, principles of work, sensing substances, transduction mechanisms, and production technologies. Furthermore, performance characteristics of the different humidity sensors such as electrical and statistical data will be detailed and gives an added value to the report. By comparison of overall prospects of the sensors it was revealed that there are still drawbacks as to efficiency of sensing elements and conduction values. The flexibility offered by thick film and thin film processes either in the preparation of materials or in the choice of shape and size of the sensor structure provides advantages over other technologies. These ceramic sensors show faster response than other types.

    OBJECTIVES: Health technology assessment (HTA) can increase the appropriateness and transparency of pricing and reimbursement decisions. Jordan is still in the early phase of its HTA implementation, although the country has very limited public resources for the coverage of healthcare technologies. The study objective was to explore and validate priorities in the HTA road map for Jordan and propose to facilitate the preferred HTA status.

    METHODS: Health policy experts from the public and private sectors were asked to participate in a survey to explore the current and future status of HTA implementation in Jordan. Semistructured interviews with senior policy makers supported by literature review were conducted to validate survey results and make recommendations for specific actions.

    RESULTS: Survey and interview results indicated a need for increased HTA training, including both short courses and academic programs and gradually increasing public funding for technology assessment and appraisal. Multiple HTA bodies with central coordination can be the most feasible format of HTA institutionalization. The weight of cost-effectiveness criterion based on local data with published reports and explicit decision thresholds should be increased in policy decisions of pharmaceutical and nonpharmaceutical technologies.

    CONCLUSION: Currently, HTA has limited impact on health policy decisions in Jordan, and when it is used to support pharmaceutical reimbursement decisions, it is mainly based on results from other countries without considering transferability of international evidence. Policy makers should facilitate HTA institutionalization and use in policy decisions by increasing the weight of local evidence in HTA recommendations.

    BACKGROUND AND PURPOSE: Evaluation of health information systems (HIS) enables the assessment of the extent to which HIS are fulfilling their objectives in supporting the services of healthcare delivery. This paper presents an overview of evaluation in health informatics and information systems.
    METHODS: Literature review on discourses, dimensions and methods of HIS and IS evaluation. A critical appraisal of selected HIS and IS evaluation frameworks is undertaken in order to identify HIS evaluation dimensions and measures. The frameworks are compared based on their inclusion of human, organizational and technological factors.
    RESULTS: We found that an increasing number of evaluation studies deal with two distinct trends of HIS: one considers human and organizational issues and the other is concerned with the employment of a subjectivist approach. Our review indicates that current evaluation methods complement each other in that they evaluate different aspects of HIS and they can be improved upon.
    CONCLUSIONS: Evaluation is complex; it is easy to measure many things but not necessarily the right ones. Nevertheless, it is possible to consider, a HIS evaluation framework with more comprehensive and specific measures that would incorporate technological, human and organizational issues to facilitate HIS evaluation.

    This paper explores the characteristics of health technology assessment (HTA) systems and practices in Asia. Representatives from nine countries were surveyed to understand each step of the HTA pathway. The analysis finds that although there are similarities in the processes of HTA and its application to inform decision making, there is variation in the number of topics assessed and the stakeholders involved in each step of the process. There is limited availability of resources and technical capacity and countries adopt different means to overcome these challenges by accepting industry submissions or adapting findings from other regions. Inclusion of stakeholders in the process of selecting topics, generating evidence, and making funding recommendations is critical to ensure relevance of HTA to country priorities. Lessons from this analysis may be instructive to other countries implementing HTA processes and inform future research on the feasibility of implementing a harmonized HTA system in the region.
