Abstract
Objective
In Canada, population norms are only available for 2 provinces, Alberta and Quebec. The objective of this study was to derive the population norms for the EQ-5D-5L based on a representative sample of the Canadian general population.
Methods
Data from the Canadian EQ-5D-5L valuation study, a cross-sectional study, were used. A quota sampling method was used to recruit a representative sample of the Canadian general population in terms of age, sex, and education. EQ-5D-5L utilities and EQ VAS were summarized using descriptive statistics and the impact of demographic characteristics on the EQ-5D-5L utilities was evaluated using statistical hypothesis testing and Tobit regression.
Results
1207 eligible participants were included in the analysis. Pain/discomfort (53.1%) was the most frequently reported domain with any problem, and self-care (7.6%) domain was the least. The mean (standard deviation [SD]) EQ-5D-5L utility was 0.864 (0.121) and the mean (SD) EQ VAS was 82.3 (14.23). The highest mean EQ-5D-5L utility was 0.881 in age group 25–34 while the lowest was 0.839 in age group 55–64. Participants who had full-time employment, were married, a higher annual household income and no chronic health conditions had significantly higher EQ-5D-5L utilities.
Conclusion
This article reports the first Canadian population norms for the EQ-5D-5L and can be used as population references for economic evaluations and clinical research.
