    OBJECTIVES: Early access to innovative oncology medicine is crucial to provide better treatment alternatives to patients with cancer. However, innovative oncology medicines often come at higher prices, thus limiting the government's ability for its universal coverage. Hence an alternative paying mechanism is needed. This study is intended to determine the willingness to pay (WTP) for innovative oncology medicines among Malaysians.

    METHODS: A cross-sectional contingent valuation study on 571 Malaysians was conducted to elicit respondents' WTP value via bidding game approach. A double-bounded dichotomous choice was used in 3 hypothetical scenarios: innovative diabetes medicine, innovative oncology medicine one-off (IOMO), and innovative oncology medicine insurance. Univariate logistic regression was used to determine the factors affecting respondent's WTP, whereas the mean WTP value and the factors affecting amount to WTP was determined using a parametric 2-part model.

    RESULTS: This study received 95% response rate. The mean age of the respondents is 48 years (SD 17) with majority of the respondents female (60.3%) and from ethnic Malay (62%). About 343 (64.7%) of the respondents expressed WTP for IOMO. Those in higher income bracket were willing to pay more for the access of IOMO than the overall WTP mean value (P = .046, coefficient 351.57).

    CONCLUSIONS: More than half of Malaysian are willing to pay for IOMO at mean value of Malaysian Ringgit 279.10 (US dollar 66.77). Collaborative funding mechanisms and appropriate financial screening among the stakeholders could be introduced as methods to expedite the access of innovative oncology medicine among patients with cancer in Malaysia.

    OBJECTIVES: Alzheimer's disease (AD) has become one of the most prevalent neurodegenerative disorders among the elderly. The global cost of dementia is expected to reach US $2 trillion in 2030. In this systematic review, existing evidence on the cost of dementia specific to AD is appraised.

    METHODS: A comprehensive search was done on 3 databases, namely PubMed, ScienceDirect, and Web of Science, to identify original cost-of-illness studies that only evaluate the economic burden of AD up to August 2022. The risk of bias in the studies was assessed using Consolidated Health Economic Evaluation Reporting Standards 2022 criteria. Cost articles without specifying etiology of AD or those in non-English were excluded.

    RESULTS: Twelve of 5536 studies met the inclusion criteria. The total annual cost of AD per capita ranged from US $468.28 in mild AD to US $171 283.80 in severe AD. The cost of care raised nonlinearly with disease severity. Indirect caregiving cost represented the main contributor to societal cost in community-dwelling patients. When special caregiving accommodation was opted in daily care, it results in cost shifting from indirect cost to direct nonmedical cost. Formal caregiving accommodation caused increase in direct cost up to 67.3% of overall economic burden of the disease.

    CONCLUSIONS: AD exerts a huge economic burden on patients and caregivers. Overall rise of each cost component could be anticipated with disease deterioration. Choice of special caregiving accommodation could reduce caregiver's productivity loss but increase the direct nonmedical expenditure of the disease from societal perspective.

    OBJECTIVES: This study aims to evaluate the cost-effectiveness of various glucose-lowering therapies as add-on to standard care for people with type 2 diabetes (T2D) in Malaysia.

    METHODS: A state-transition microsimulation model was developed to compare the clinical and economic outcomes of 4 treatments: standard care, dipeptidyl peptidase-4 inhibitors, sodium-glucose cotransporter-2 inhibitors (SGLT2is), and glucagon-like peptide-1 receptor agonists. Cost-effectiveness was assessed from a healthcare provider's perspective over a lifetime horizon with 3% discount rate in a hypothetical cohort of people with T2D. Data input were informed from literature and local data when available. Outcome measures include costs, quality-adjusted life-years, incremental cost-effectiveness ratios, and net monetary benefits. Univariate and probabilistic sensitivity analyses were performed to assess uncertainties.

    RESULTS: Over a lifetime horizon, the costs to treat a person with T2D ranged from RM 12 494 to RM 41 250, whereas the QALYs gains ranged from 6.155 to 6.731, depending on the treatment. Based upon a willingness-to-pay threshold of RM 29 080 per QALY, we identified SGLT2i as the most cost-effective glucose-lowering treatment, as add-on to standard care over patient's lifetime, with the net monetary benefit of RM 176 173 and incremental cost-effectiveness ratios of RM 12 279 per QALY gained. The intervention also added 0.577 QALYs and 0.809 LYs compared with standard care. Cost-effectiveness acceptability curve showed that SGLT2i had the highest probability of being cost-effective in Malaysia across varying willingness-to-pay threshold. The results were robust to various sensitivity analyses.

    CONCLUSIONS: SGLT2i was found to be the most cost-effective intervention to mitigate diabetes-related complications.

    OBJECTIVES: This review explores the cost-effectiveness of the strategies used in the breast cancer early detection programs of low- to middle-income countries.

    METHODS: A systematic review was performed to identify related studies, published up to August 2021, on PubMed, Cochrane, ProQuest, and the Cumulative Index to Nursing and Allied Health Literature. The Cochrane Handbook and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol were referenced during the reporting process. The Consolidated Health Economic Evaluation Reporting Standards 2022 criteria were used to assess the requirements of the selected studies. Articles with original data and full texts were included in the review. Non-low- to middle-income countries and non-English articles were excluded.

    RESULTS: This review identified 12 suitable studies, wherein 6 investigated the cost-effectiveness of clinical breast examinations (CBEs), whereas 10 looked into mammogram (MMG) with or without CBE. In 2 studies, the cost-effectiveness of raising awareness through mass media and the use of ultrasounds combined with CBE were investigated. Although cost-effective, MMG incurs greater costs and requires more skill to be performed. MMG screenings before the age of 40 years were not cost-effective. The limitations of this review include variability in the methodological approaches of its selected studies. Most of the chosen studies met the Consolidated Health Economic Evaluation Reporting Standards 2022 criteria.

    CONCLUSIONS: This review shows that adopting an age- and risk-based MMG screening approach could be viable in countries with limited resources. Future cost-effectiveness analysis research should include a section on patient and stakeholder engagement with the study's results.

    OBJECTIVES: This study aimed to translate the Medication Use Questionnaire into a Malay version, adapt it to Malaysia's culture, and verify its reliability among Malaysia's older adults.

    METHODS: Methodological approaches were used to translate, validate, and modify the questionnaire. The subjects were older adults aged ≥ 60 years in primary care settings in Penang, Malaysia. Two forward translations (English to Malay) were developed, reviewed, and back translated to English. The reconciliation phase was conducted to compare the translated and original questionnaires. Five older adults were then interviewed for the cognitive debriefing of the reconciled questionnaire to assess the linguistic and cultural equivalence. Two experts assessed content validity, and the translated questionnaire was proofread and finalized. After that, pilot test was done to examine the internal consistency among 20 older adults.

    RESULTS: Translation of the questionnaire was done with no major disagreements. The main issues identified in cognitive debriefing and content validity were terms, number of questions, and phrases used in the questionnaire. Most participants reported that the questionnaires were not difficult to complete during the cognitive debriefing phase. The issues were then judged and revised accordingly. Further pilot testing on 20 older adults demonstrated good internal consistency reliability, Cronbach α (0.902).

    CONCLUSIONS: This study findings suggest promising data supporting the use of translated version of the Medication Use Questionnaire that can be used to identify medication use problems among older adults in Malaysia.

    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.

    OBJECTIVES: To examine the budget impact of emicizumab as prophylactic therapy in reducing the frequency of bleeding episodes in patients with hemophilia A with inhibitors in Malaysia.

    METHODS: A budget impact model was built to assess the cost implication of introducing emicizumab for routine prophylaxis of bleeding episodes in people with hemophilia A with inhibitors. It was based on the public healthcare system in Malaysia over a 5-year duration. The primary analysis computed healthcare costs for emicizumab compared with no prophylactic regimen to calculate the budget needed to treat all patients with hemophilia A with inhibitors.

    RESULTS: The introduction of emicizumab resulted in a total incremental budget of Malaysian Ringgit (RM) 20 356 897 ($4 917 125) during the first year. The total cost for the current situation (no prophylaxis) was RM13 425 941 ($3 242 981), whereas the total cost for the new situation (prophylaxis with emicizumab) was RM33 782 838 ($8 160 106). The 5-year cumulative incremental budget impact from 2021 to 2025 was RM97 205 459 ($23 479 579) with an uncertainty range from -RM4 869 886 (-$1 176 301) to RM138 035 597 ($33 341 932) and a total of 72 patients treated with emicizumab. In a sensitivity analysis, the use of emicizumab was cost saving if the annual bleeding rate was greater than 16 instead of 6 times per year.

    CONCLUSION: The 5-year budget impact might be considered reasonable and possibly cost saving. The model and approach used in this study to obtain relevant parameters where scarce data exist may help other jurisdictions with future adaptation.

    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.

    OBJECTIVES: Globally, nutraceuticals have been increasingly used. Nevertheless, the consumer preferences for nutraceuticals have not been quantitatively investigated. This study used discrete choice experiment (DCE) to examine consumer preferences and willingness to pay for nutraceuticals.

    METHODS: Four attributes (ie, the scientific proof of effectiveness, the scientific proof of safety, the source of recommendation, and cost) were identified from a systematic review and focus group interviews. They were used to develop a DCE questionnaire. Consumers at community pharmacies in Malaysia were asked to respond to 8 DCE choice sets. A conditional logit model was employed to obtain the relative importance of each attribute and to estimate respondents' WTP for nutraceuticals.

    RESULTS: A total of 111 valid responses were analyzed. A negative constant term in the developed model indicated that generally the respondents preferred not to use nutraceuticals before they considered the study attributes. The respondents preferred nutraceuticals with no side effect, clear evidence of effectiveness, and recommendation of a healthcare professional. The respondents were willing to pay $252/month more for nutraceuticals proven with no side effect than for those without proof of safety, and $102/month more for nutraceuticals proven with clear effectiveness than for those without proof of effectiveness.

    CONCLUSIONS: Consumers weighed relatively high on the availability of safety and effectiveness proofs when they chose nutraceuticals. The study highlights on the crucial need to inform consumers using clinical evidences of nutraceuticals as the information is highly preferred by consumers.

    OBJECTIVE: The objective of this study was to examine the cross-sectional convergent and known-group validity of the Malay-language EQ-5D-3L instrument in children and adults with transfusion-dependent thalassemia (TDT).

    METHODS: A cross-sectional health-related quality of life survey involving TDT patients from 12 different treatment centers across Malaysia was conducted using the Malay PedsQL 4.0 Generic Core Scales and the Malay EQ-5D-3L questionnaire. Patients with non-TDT and other hemoglobinopathies were excluded. Convergent, discriminant, and known-group validity of the EQ-5D-3L was assessed against the PedsQL 4.0 Generic Core Scales in children. In the adult population, known-group validity of the EQ-5D-3L was assessed using an a priori hypothesis between patients' demographic characteristics and health outcomes obtained from literature.

    RESULTS: A total of 370 children and 225 adults were sampled. The mean (standard deviation) EQ-5D-3L scores of the children were 0.892 (0.082) and the adults were 0.887 (0.085). Convergent and discriminant validity was identified when correlated with the PedsQL domain in children. In both groups, known-group validity was evident when comparing groups of patients with reported problems to the group of patients with no reported problems on the EQ-5D-3L domains based on the a priori hypothesis derived from literature.

    CONCLUSION: This study found convergent, discriminant, and known-group validity of the Malay EQ-5D-3L in a population-based sample of patients with TDT. Hence, the instrument is valid for the assessment of health-related quality of life in children and adults with TDT in Malaysia.

    OBJECTIVES: To evaluate the validity and reliability of the 5-level EuroQol 5-dimensional questionnaire (EQ-5D-5L) through classical test theory and the Rasch measurement model.

    METHODS: Three hundred patients treated for uncomplicated malaria in selected primary healthcare facilities of Plateau state, Nigeria, completed the EQ-5D-5L scale. Classical test theory was used to establish validity and Cronbach's alpha reliability of the scale. Rasch analysis was used to confirm the unidimensionality, item fitness, item and person separations and reliabilities, and targeting of item difficulty to patient ability levels and presentation on Wright map (item-person map).

    RESULTS: The outcome of classical test theory revealed unidimensional scale with average variance extracted values > 0.5, and the square root of the average variance extracted for construct was greater than the correlation coefficients, indicating convergent and discriminant validities of the scale whose Cronbach's alpha coefficient (α) was 0.87. Rasch analysis indicated variance explained values of 88.3% and the eigenvalues of the first contrast was 1.3, further confirming the unidimensionality of the scale, whose fit index values were within accepted ranges. The high item and person separation and reliability values indicated the instrument's strength in detecting and evenly spreading items and persons on the Wright map based on item difficulty and the respondents' ability levels, respectively.

    CONCLUSION: The EQ-5D-5L scale performed well in uncomplicated malaria, hence, it is recommended for use in the assessment of health-related quality of life in this patient population.

    BACKGROUND: Candidemia or invasive candidiasis (IC) is an increasingly common fungal infection and has been associated with high mortality, particularly among the immunocompromised and critically ill. Although several studies have been conducted to estimate the cost of managing candidemia and IC, quality assessment on the methodological aspects of these cost studies was not performed. To date, no systematic review focusing on the economic burden of candidemia and IC has ever been conducted.

    OBJECTIVES: The aim of this study was to systematically review the available evidence on the economic burden of candidemia and IC worldwide.

    METHODS: Databases (ie, PubMed, Scopus, EconLit, HEORO, and Ovid/Embase) were searched through June 2018. Two researchers independently assessed the quality of the eligible studies. Costs reported in the included studies were converted to 2016 USD using Campbell and Cochrane Economics Methods Group-the Evidence for Policy and Practice Information (CCEMG-EPPI)-Centre Cost Converter software.

    RESULTS: Eight articles were included in this systematic review. The mean total cost per patient with candidemia and IC ranged from $48 487 to $157 574, whereas the mean cost per hospitalization associated with candidemia and IC was from $10 216 to $37 715. All studies were from developed Western countries and reported only direct costs of candidemia and IC. Hospitalization was the main cost driver, contributing to more than half of the total costs.

    CONCLUSION: Quality cost studies on candidemia and IC based on standardized methods to provide informed decision making among healthcare authorities in implementing appropriate strategies is anticipated, in particular in developing countries.

    OBJECTIVE: To identify and describe the various economic evaluation studies in Malaysia and to determine the range of incremental cost-effectiveness ratios (ICERs) as reported in these studies.

    METHODS: A comprehensive search of the scientific electronic databases was conducted (Medline, EBM Reviews, Embase, and hand search) to identify all published economic evaluation studies related to Malaysian healthcare. Two researchers assessed the quality of selected studies using the Critical Appraisal Skills Programme (CASP) checklist and Quality of Health Economic Studies instrument. The assessment was also reviewed by expert members of the Technical Advisory Committee of Health Technology Economic Evaluations (TACHTEE).

    RESULTS: A total of 64 full-text articles were assessed for eligibility and included in this systematic review. Thirty studies were partial economic evaluations; the full economic evaluations included 17 cost-effectiveness analyses and 17 cost-utility analyses. From all the reported ICERs, the majority (68%) were categorized as highly cost-effective (ICER of less than 1 gross domestic product (GDP) per capita per quality-adjusted life-years or disability-adjusted life-years gained).

    CONCLUSION: This review identifies information gaps and loopholes in health economics research in Malaysia. Additionally, this study provides the information that the majority of published interventions in Malaysia fell within the cost-effectiveness threshold of 1 GDP per capita per quality-adjusted life-years or disability-adjusted life-years gained.

    OBJECTIVES: The present systematic review aimed to assess the healthcare financing system by studying the relevant indicators in low- and middle-income countries (LMICs). The focus of this research was on the entire healthcare system without considering any specific healthcare service or population group. This article explains the conditions of equity in people's payments for healthcare services in LMICs and focuses on the strengths and weaknesses of successful or failed healthcare systems.

    METHODS: A systematic search was conducted in the existing database that included the data up to December 2016. The quantity of equity was estimated using relevant indicators and comparing the results with indicators' specific values. Narrative synthesis was then performed for the purpose of reporting the results.

    RESULTS: A total of 17 articles from 14 regions, including Palestine, China, China (Heilongjiang), China (Gansu), Ghana, Hungary, Iran, Tunisia, Tanzania, Malaysia, Malawi, Zimbabwe, Uganda, and Chile met the inclusion criteria. The findings indicated that the insurance system (individual and social) is the most equitable method of financing, whereas direct payment is the most unfair method. Nevertheless, many countries still struggle with various payment methods, and people use direct payments.

    CONCLUSIONS: Results revealed that several factors can affect a country's failure to establish equity in financing the health system. These factors include an increase in direct payments by people to reduce the government's share, failure to cover insurance for the entire population (and especially the poor), and problems in identifying people from low-income groups and setting rules for exempting them from taxes.

    OBJECTIVES: Escalating healthcare costs calls for the efficiency of health services, especially in the intensive care unit (ICU) where the bulk of resources are used. This study aims to identify the length of stay (LOS) and cost of care at ICUs, which are proxy indicators of efficiency and the factors determining them.

    METHODS: A cross-sectional study of patients requiring ICU admissions in a teaching hospital in Malaysia from 2013 to 2015 was conducted. The cost at the ICU was estimated using the step down approach. Factors that determined the cost and LOS at the ICU were also explored by using multivariate regression analysis.

    RESULTS: Each day of stay cost $427 (USD) at the pediatric intensive care unit and $1324 at the general intensive care unit. The mean LOS at the ICU was 5.7 days (standard deviation [SD]: 8.4) with a median of 4 days (95% confidence interval [CI] 1-16.7 days). Average cost of care at the ICU per episode of care was $5473 (SD $6499), and the median was $3463. ICU patients spent 29.3% of the total stay and 47.2% of the cost at ICU units. Upon multivariate regression analysis, severity, case base-group, and type of ICU that the patient was admitted to were associated with the cost and LOS at ICU.

    CONCLUSIONS: Compared with critical care practices in hospitals from more developed nations, a Malaysian teaching hospital required a longer length of ICU stay. Hence, implementations of strategies that can reduce the length of stay and hospital costs without compromising healthcare quality are required.

    OBJECTIVES: The combination of pegylated-interferon and ribavirin (PegIFN+RBV) is currently the gold standard in treating chronic hepatitis C virus (HCV) patients in Malaysia and is reimbursed by the Malaysian authorities. This analysis evaluated the cost-effectiveness (CE) of the ombitasvir/paritaprevir/ritonavir and dasabuvir with or without ribavirin (OBT/PTV/r+DSB±RBV) regimen as compared with the PegIFN+RBV or no treatment in chronic HCV Genotype 1 (GT1) treatment-naïve and treatment-experienced cirrhotic and noncirrhotic patients in Malaysia.

    METHODS: A Markov model based on previously published CE models of HCV was adapted for the Malaysian public healthcare payer perspective, based on good modeling practices. Treatment attributes included efficacy, regimen duration, and EQ-5D treatment-related health utility. Transitional probabilities and health state health utilities were derived from previous studies. Costs were derived from Malaysian data sources. Costs and outcomes were discounted at 3.0% per year. Deterministic and probabilistic sensitivity analyses were performed to evaluate the impact of uncertainties around key variables.

    RESULTS: Based on the analysis, patients treated with the OBT/PTV/r+DSB±RBV showed less frequent progression to compensated cirrhosis, decompensated cirrhosis, hepatocellular carcinoma, and liver-related deaths when compared with standard care (ie, PegIFN+RBV or no treatment). At a price of MYR 1846/day, the OBT/PTV/r+DSB±RBV regimen is cost-effective over PegIFN+RBV and yields better outcomes in terms of life-years (LYs) gained and quality-adjusted life-years (QALYs) at a higher cost, which is still well below the implied willingness to pay threshold of MYR 384 503/QALY.

    CONCLUSION: The OBT/PTV/r+DSB±RBV regimen is cost-effective for treatment naïve, treatment experienced, cirrhotic, and noncirrhotic GT1 chronic HCV patients in Malaysia.

    OBJECTIVES: Countries have constrained healthcare budgets and must prioritize new interventions depending on health goals and time frame. This situation is relevant in the sphere of national immunization programs, for which many different vaccines are proposed, budgets are limited, and efficient choices must be made in the order of vaccine introduction.

    METHODS: A constrained optimization (CO) model for infectious diseases was developed in which different intervention types (prophylaxis and treatment) were combined for consideration in Malaysia. Local experts defined their priority public health issues: pneumococcal disease, dengue, hepatitis B and C, rotavirus, neonatal pertussis, and cholera. Epidemiological, cost, and effectiveness data were informed from local or regionally published literature. The model aimed to maximize quality-adjusted life-year (QALY) gain through the reduction of events in each of the different diseases, under budget and intervention coverage constraints. The QALY impact of the interventions was assessed over 2 periods: lifetime and 20 years. The period of investment was limited to 15 years.

    RESULTS: The assessment time horizon influenced the prioritization of interventions maximizing QALY gain. The incremental health gains compared with a uninformed prioritization were large for the first 8 years and declined thereafter. Rotaviral and pneumococcal vaccines were identified as key priorities irrespective of time horizon, hepatitis B immune prophylaxis and hepatitis C treatment were priorities with the lifetime horizon, and dengue vaccination replaced these with the 20-year horizon.

    CONCLUSIONS: CO modeling is a useful tool for making economically efficient decisions within public health programs for the control of infectious diseases by helping prioritize the selection of interventions to maximize health gain under annual budget constraints.

    OBJECTIVES: To calculate the total revenue under a hypothetical 1 Malaysian Ringgit (MYR) prescription cost sharing model in government healthcare facilities in Pahang, Malaysia.

    METHODS: A cross-sectional study was conducted at outpatient pharmacy in all government healthcare facilities in Pahang from year 2013 to 2017. Each dispensed medication was calculated as 1 MYR and contributed to the total revenue.

    RESULTS: A total of 11 hospitals and 81 health clinics were recruited into the study. A hospital could generate 0.311 million MYR per year, and a district health department could generate 0.623 million MYR per year, giving a total of 10.268 million MYR revenue every year in Pahang, Malaysia. Under the prescription medicines cost sharing scheme, it was shown that an average of 9.4% of the total pharmaceutical spending could be recovered. The recovery percentage was approximately fourfold higher in health clinics (16.5%-21.7%) when compared with that in hospitals (4.3%-5.2%).

    CONCLUSION: An estimated 10 million MYR or 10% from the total Ministry of Health pharmaceutical spending could be collected under the proposed 1 MYR prescription cost sharing model.

    OBJECTIVES: To describe the process, challenges, and future direction of health technology assessment (HTA), focusing on the drug selection of the National List of Essential Medicines (NLEM) in Thailand.

    METHODS: Literature and government documents were reviewed and analyzed by authors with experiences in HTA and drug policy in the country.

    RESULTS: The structure of HTA and its process in the drug selection of the NLEM were described, followed by the outcomes of the use of HTA. Examples of lowering drug prices, as a result of price negotiation using HTA, were presented. A few examples were also provided to demonstrate how decisions were made from considering factors beyond cost-effectiveness findings. Finally, challenges on various issues including improvement of HTA structure and process were discussed for the future direction of HTA in Thailand.

    CONCLUSIONS: HTA has been adopted as a tool for the drug selection of the NLEM to help Thailand achieve universal health coverage. Nevertheless, various challenges exist and need to be addressed.

    Medicine price directly affects affordability and access to medicines particularly in countries where a major portion of pharmaceutical spending is through out-of-pocket payment, such as in the Asia Pacific region. We have undertaken a detailed appraisal of the pharmaceutical policy reforms to regulate drug prices in 3 developed (Australia, New Zealand, and South Korea) and 3 emerging (China, India, and Malaysia) economies of the Asia Pacific region. Despite continuous efforts by the authorities in adopting a wide range of reformatory pharmaceutical pricing policies to ensure affordability of medicines, these policies may not be optimal where drug prices were not lowered as expected (eg, in Korea). On the contrary, considerable price reductions of various pharmaceuticals have been observed in New Zealand and India because of the reform in pharmaceutical pricing policy. This review of pharmaceutical pricing reforms reinforces the need for constant monitoring by policy makers in Asia Pacific countries to regulate drug prices and to undertake reform in pharmaceutical pricing policies when necessary to ensure affordability and access to medicines.
