EQ-5D-5L Values and Determinants for a Vietnamese Population.

Area of Science:

• Health Economics
• Public Health
• Epidemiology

Background:

• Health-related quality of life (HRQoL) is crucial for population health assessment.
• Updated HRQoL data specific to the Vietnamese population is needed for accurate health economic evaluations.
• The EQ-5D-5L instrument is a widely used tool for measuring HRQoL.

Purpose of the Study:

• To update health-related quality of life (HRQoL) data in the Vietnamese population using the EQ-5D-5L instrument.
• To identify sociodemographic and health-related factors associated with HRQoL in Vietnam.
• To provide current data for healthcare planning and health economic evaluations in Vietnam.

Main Methods:

• A cross-sectional online survey was conducted with 3550 Vietnamese adults (aged 18+).
• Participants were recruited via convenience and snowball sampling through online platforms.
• HRQoL was measured using the EQ-5D-5L index and EQ-VAS, with data analyzed using descriptive statistics and multivariable Tobit regressions.

Main Results:

• The mean EQ-5D-5L index score was 0.896 and the mean EQ-VAS score was 86.7.
• Significant differences in HRQoL were observed across age groups, employment status, education levels, and chronic disease presence (p < 0.001).
• Older age, unemployment, lower education, and multiple morbidities were independently associated with lower HRQoL.

Conclusions:

• The study provides updated HRQoL data for Vietnam, highlighting the influence of age, socioeconomic status, and health conditions.
• Findings confirm that sociodemographic factors and health status significantly impact HRQoL in the Vietnamese population.
• The results are valuable for informing healthcare planning, health economic evaluations, and public health interventions in Vietnam.
