    • The under-representation of several ethnic groups in existing genetic databases and studies have undermined our understanding of the genetic variations and associated traits or diseases in many populations. Cost and technology limitations remain the challenges in performing large-scale genome sequencing projects in many developing countries, including Vietnam. As one of the most rapidly adopted genetic tests, non-invasive prenatal testing (NIPT) data offers an alternative untapped resource for genetic studies. Here we performed a large-scale genomic analysis of 2683 pregnant Vietnamese women using their NIPT data and identified a comprehensive set of 8,054,515 single-nucleotide polymorphisms, among which 8.2% were new to the Vietnamese population. Our study also revealed 24,487 disease-associated genetic variants and their allele frequency distribution, especially 5 pathogenic variants for prevalent genetic disorders in Vietnam. We also observed major discrepancies in the allele frequency distribution of disease-associated genetic variants between the Vietnamese and other populations, thus highlighting a need for genome-wide association studies dedicated to the Vietnamese population. The resulted database of Vietnamese genetic variants, their allele frequency distribution, and their associated diseases presents a valuable resource for future genetic studies.

  • An EQ-5D-5L value set for Vietnam
  • 2020
  • Ingår i: Quality of Life Research. - : Springer Netherlands. - 0962-9343 .- 1573-2649. ; 29, s. 1923-1933

    • PURPOSE: The objective of this study was to develop an EQ-5D-5L value set based on the health preferences of the general adult population of Vietnam.METHODS: The EQ-VT protocol version 2.1 was applied. Multi-stage stratified cluster sampling was employed to recruit a nationally representative sample. Both composite time trade-off (C-TTO) and discrete choice experiment (DCE) methods were used. Several modelling approaches were considered including hybrid; tobit; panel and heteroscedastic models. First, models using C-TTO or DCE data were tested separately. Then possibility of combining the C-TTO and DCE data was examined. Hybrid models were tested if it was sensible to combine both types of data. The best-performing model was selected based on both the consistency of the results produced and the degree to which models used all the available data.RESULTS: Data from 1200 respondents representing the general Vietnamese adult population were included in the analyses. Only the DCE Logit model and the regular Hybrid model that uses all available data produced consistent results. As the priority was to use all available data if possible, the hybrid model was selected to generate the Vietnamese value set. Mobility had the largest effect on health state values, followed by pain/discomfort, usual activities, anxiety/depression and self-care. The Vietnam values ranged from - 0.5115 to 1.CONCLUSION: This is the first value set for EQ-5D-5L based on social preferences obtained from a nationally representative sample in Vietnam. The value set will likely play a key role in economic evaluations and health technology assessments in Vietnam.

  • A feasibility and applicability study of a health-related quality of life measurement in Vietnam
  • 2023
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Introduction: An evidence-based strategy is used the national social health-insurance programme in Vietnam to assess healthcare technologies. Health technology assessments (HTA) have become increasingly important within decision-making processes. This doctoral project involved developing a health-related quality of life (HRQOL) measurement to be used in HTA in Vietnam.Methodology: The doctoral project used a mixed-methods approach, which comprised a health-preference elicitation study using a combination of time-trade-off and discrete choice experiments method for the EQ-5D-5L, as recommended by the EuroQol Group (Objective 1). The project incorporated a validity study that utilised secondary data (Objective 2), a cost-utility analysis that utilised both secondary data and normative costing data (Objective 3), and a qualitative study that utilised empirical data (Objective 4). Additionally, the doctoral project resulted in an EQ-5D-5L reference dataset for the general population of Vietnam.Results: A generic preference-based HRQOL measurement was developed for the Vietnamese population using the EQ-5D-5L instrument. This tool can be utilised not only as an outcome measurement for HTA, but in other health-science disciplines. The EQ-5D-5L comprises a descriptive system with five questions, a visual analogue scale (EQ-VAS), and a value set that facilitates the assignment of health-state values (Sub-study 1). The doctoral project proposed an EQ-5D-5L reference dataset that could serve as a basis for HRQOL comparison in Vietnam (Sub-study 2). It has added evidence on the validity of the EQ-5D-5L for the Vietnamese population through a known-groups validation conducted on individuals with hypertension (Sub-study 2). This validation has facilitated the establishment of a favourable environment for the implementation of this tool in Vietnam. Additionally, the satisfactory performance of the EQ-5D-5L has been shown in producing data that is useful for the cost utility analysis in Vietnam (Sub-study 3). Despite concerns regarding the appropriateness of the EQ-5D-5L in reflecting HRQOL for disease-specific populations, the tool has been accepted and is commonly used in Vietnam (Sub-study 4).Conclusion: The outcomes of the doctoral project are a favourable HTA environment, facilitation of evidence-based decision-making, and contribution to the goal of achieving universal health coverage in Vietnam.

  • Reference data among general population and known-groups validity among hypertensive population of the EQ-5D-5L in Vietnam
  • 2022
  • Ingår i: Quality of Life Research. - : Springer Nature. - 0962-9343 .- 1573-2649. ; 31, s. 539-550

    • Purpose: This study aims to provide EQ-5D-5L population norms among the general population in Vietnam and to test EQ-5D-5L’ construction validity among people living with hypertension there.Methods: Descriptive statistics of the five dimensions and five levels, EQ-VAS and EQ-5D-5L indexes were categorised into gender and age groups for the EQ-5D-5L population norms. Known-groups testing was set for lower EQ-5D-5L outcomes among people who were aware of their hypertensive status, females, people with more comorbidities, less education, older ages, and higher body mass indexes. Level of confident interval was 95%.Results: The mean EQ-VAS and EQ-5D-5L indexes were 81.10 (SD: 13.35) and 0.94 (SD: 0.09) among the general population. The EQ-5D-5L outcomes were better among younger people, males, people with more education, employees, and single people. Respondents reported fewer problems with self-care and usual activities and tend to have problems at higher levels across older ages. The known-group testing showed statistically significant results. The mean EQ-VAS and EQ-5D-5L indexes of people in the diagnosed hypertensive group (71.48 and 0.94, respectively) were statistically significantly smaller than they were in the non-hypertensive and undiagnosed hypertensive group (76.65 and 0.97; 76.95 and 0.96 accordingly). Statistically significant associations of lower EQ-5D-5L indexes and EQ-VAS were found among people diagnosed for hypertension, people suffering from an incremental comorbidity, and obese people.Conclusion: This study has provided EQ-5D-5L population norms for the general population and evidence for known-groups validity of the EQ-5D-5L instrument among hypertensive people in Vietnam.
