Population norms for the EQ-5D-3L in China derived from the 2013 National Health Services Survey.

ABSTRACT:

Background

EQ-5D-3L is one of the most commonly used instruments for assessing health-related quality of life and cost-utility analyses, but it is not yet available in China. This study aims to develop population norms for the EQ-5D-3L in China in order to encourage appropriate use and interpretation of the EQ-5D-3L instrument.

Methods

Data were extracted from the 2013 National Health Services Survey on a nationally representative sample of 188?720 participants. The utility index based on the 2018 Chinese preference-based value sets were calculated for the participants with different demographic and socio-economic characteristics. Differences in reported problems and visual analogue scale (VAS) and utility index scores were tested using a logistic, linear and tobit regression model, respectively.

Results

The Chinese respondents were less likely to report problems on the EQ-5D dimensions compared with most populations in other countries. Pain/discomfort was the most commonly reported problem (12.6%). This resulted in a high ceiling effect (84.19%) on the utility index and high mean scores for the utility index (0.985?±?0.056) and VAS (80.91?±?13.74) in the Chinese population. Those who were younger, better educated, employed, married, had no illness condition, lived in a more developed region and had a higher income obtained higher scores in both VAS and utility index. The VAS and utility index scores were also associated with gender, residency and lifestyles, but not always in a consistent way. Male and rural residents had a higher VAS score but not in the utility index compared with their female and urban counterparts.

Conclusions

This study provides national population norms for the EQ-5D-3L based on the 2018 Chinese preference-based value sets. The norms can be used as a reference for health evaluation studies. Cautions need to be taken for presenting and interpreting the utility index results given the high ceiling effect of the EQ-5D-3L instrument.

Project description:BackgroundThe majority of patient reported outcome measures (PROMs) don't have population norms in Romania. This is the case with the EQ-5D as well. Therefore, we aimed to estimate population norms for the Romanian versions of the EQ-5D-5L, EQ-5D-3L, their indexes, and the EQ-VAS.MethodsA cross-sectional survey was conducted in all regions of Romania from November 2018 to November 2019. A three-stage probability sampling procedure stratified by region and settlement size was used to select a representative sample. Interviews were computer-assisted and conducted in respondents' homes by trained interviewers. Health status was assessed with the EQ-5D-5L, the EQ-5D-3L and the EQ VAS. Descriptive statistics were used to estimate population norms by age groups and sex for the EQ-5D-5L, the EQ-5D-3L, their indexes and the EQ VAS. Population norms were weighted using survey weights. Indexes for the EQ-5D questionnaires were estimated using the recently developed Romanian value sets.ResultsData from 1,649 interviews was analysed in the present study. Survey weights were used so that sex and place of residence ratios for the weighted sample matched the Romanian general population distribution. Participants' mean age was 47.4 years (SE = 1.157) and 50.3% of them reported being in good health. The dimension for which people reported the highest number of problems for both questionnaires was the pain/discomfort dimension. Men aged 35 plus reported fewer problems with pain/discomfort than women for both the EQ-5D-5L and EQ-5D-3L. Health decreased with age as shown by the decrease from age group 18-24 to age group 75 plus in the indexes of both questionnaires: from 0.977 (SE = 0.005) to 0.765 (SE = 0.017) for EQ-5D-5L and from 0.981 (SE = 0.005) to 0.784 (SE = 0.019) for EQ-5D-3L. There was 29.9 points drop in the EQ VAS score between the youngest and oldest group.ConclusionsPopulation norms for the Romanian versions of the EQ-5D-5L, EQ-5D-3L, their indexes, and the EQ VAS are now available. These can now be used as reference values by healthcare professionals, researchers and decision-makers leading to a further development of health-related quality of life research in Romania.

Project description:BackgroundHealth Related Quality of Life (HRQoL) is an important outcome measure in health economic evaluation that guides health resource allocations. Population norms for HRQoL are an essential ingredient in health economics and in the evaluation of population health. The aim of this study was to produce EQ-5D-3L-derived population norms for Sri Lanka.MethodA population sample (n = 780) was selected from four districts of Sri Lanka. A stratified cluster sampling approach with probability proportionate to size was employed. Twenty six clusters of 30 participants each were selected; each participant completed the EQ-5D-3L in a face-to-face interview. Utility weights for their EQ-5D-3L health states were assigned using the Sri Lankan EQ-5D-3L algorithm. The population norms are reported by age and socio-economic variables.ResultsThe EQ-5D-3L was completed by 736 people, representing a 94% response rate. Sixty per cent of the sample reported being in full health. The percentage of people responding to any problems in the five EQ-5D-3L dimensions increased with age. The mean EQ-5D-3L weight was 0.85 (SD 0.008; 95%CI 0.84-0.87). The mean EQ-5D-3L weight was significantly associated with age, housing type, disease experience and religiosity. People above 70 years of age were 7.5 times more likely to report mobility problems and 3.7 times more likely to report pain/discomfort than those aged 18-29 years. Those with a tertiary education were five times less likely to report any HRQoL problems than those without a tertiary education. A person living in a shanty was 4.3 more likely to have problems in usual activities than a person living in a single house.ConclusionThe population norms in Sri Lanka vary with socio-demographic characteristics. The socioeconomically disadvantaged have a lower HRQoL. The trends of population norms observed in this lower middle income country were generally similar to those previously reported in high income countries.
