Measurement Properties of the EQ VAS Around the Globe: A Systematic Review and Meta-Regression Analysis.

Our aim was to systematically review published evidence on the construct validity, test-retest reliability and responsiveness of generic preference-based measures (PBMs) used in East and South-East Asia. This systematic review was guided by the COSMIN guideline. A literature search on the MEDLINE, EMBASE, PsycINFO and PubMed databases up to August 2019 was conducted for measurement properties validation papers of the EuroQol-5 Dimensions (EQ-5D), Short Form-6 Dimensions (SF-6D), Health Utilities Index (HUI), Quality of Well-Being (QWB), 15-Dimensional (15D) and Assessment of Quality of Life (AQOL) in East and South-East Asian countries. Included papers were disaggregated into individual studies whose results and quality of design were rated separately. The population-specific measurement properties (construct validity, test-retest reliability and responsiveness) of each PBM were assessed separately using relevant studies. The overall methodological quality of the studies used in each of the assessments was also rated. A total of 79 papers containing 1504 studies were included in this systematic review. The methodological quality was ‘very good’ or ‘adequate’ for the majority of the construct validity studies (99%) and responsiveness studies (61%), but for only a small portion of the test-retest reliability studies (23%). EQ-5D was most widely assessed and was found to have ‘sufficient’ construct validity and responsiveness in many populations, while the SF-6D and EuroQol-Visual Analog Scale (EQ-VAS) exhibited ‘inconsistent’ construct validity in some populations. Scarce evidence was available on HUI and QWB, but current evidence supported the use of HUI. This systematic review provides a summary of the quality of existing generic PBMs in Asian populations. The current evidence supports the use of EQ-5D as the preferred choice when a generic PBM is needed, and continuous testing of all PBMs in the region.

Measurement Properties of Commonly Used Generic Preference-Based Measures in East and South-East Asia: A Systematic Review

It is not clear whether 5-level EQ-5D (EQ-5D-5L) utilities based on recently developed value sets are more responsive than 3-level EQ-5D (EQ-5D-3L) utilities. The study aims were to compare (1) the responsiveness of EQ-5D-5L and EQ-5D-3L utilities and (2) the responsiveness of these utilities with the Short Form–6 Dimension (SF-6D) and Health Utilities Index Mark 3 (HUI3) utilities to the treatment benefit of cataract surgery. A total of 148 patients were interviewed before and after their cataract surgery using EQ-5D-3L, EQ-5D-5L, SF-6D, and HUI3. Responsiveness was assessed for all measures using the mean change (post-treatment—pre-treatment), standardized effect size (SES), standardized response mean (SRM), and F-statistic. Using the Singapore value sets, mean change for EQ-5D-3L and EQ-5D-5L utilities was 0.016 and 0.028, SES was 0.097 and 0.199; SRM was 0.091 and 0.196; and F-statistic was 1.2 and 5.7, respectively. Similar trends were observed using the UK/England EQ-5D value sets, although the magnitude was slightly smaller. The mean change, SES, SRM and F-statistics for SF-6D (UK value set) were 0.020, 0.234, 0.249, and 9.2, respectively. The values of mean change, SES, SRM and F-statistics for HUI3 (Canada value set) were 0.080, 0.472, 0.474, and 33.3, respectively. The EQ-5D-5L utilities tend to be more responsive than the EQ-5D-3L utilities to treatment benefits of cataract surgery. The HUI3 utilities are more responsive than both the EQ-5D-5L and SF-6D, and SF-6D utilities may be slightly more responsive than the EQ-5D-5L for assessing patients undergoing cataract surgery.

EQ-5D-5L is More Responsive than EQ-5D-3L to Treatment Benefit of Cataract Surgery.

This study aimed to compare the measurement properties of the EQ-5D-3L (3L) and EQ-5D-5L (5L) in cancer patients. A consecutive sample of inpatients with lung, breast, colorectal, liver, gastric, or thyroid cancer were interviewed using the 3L, 5L, and Functional Assessment of Cancer Therapy–General (FACT-G) questionnaires, and a subgroup was invited to complete the 3L and 5L again. Kappa and intraclass correlation coefficient were used to assess test–retest reliability, and Spearman’s correlation between the EQ-5D and FACT-G was evaluated to assess convergent validity. Comparison of subgroups defined using Eastern Cooperative Oncology Group status and cancer stage were performed to assess known-group validity and discriminatory power using the F-statistic and area under the receiver-operating characteristics curve. All analyses were also performed for each subgroup of cancer patients. A total of 416 cancer patients completed the baseline questionnaire and 90 patients also completed the follow-up survey after 2 days. Ceiling effects were smaller in 5L (10.1%) than in 3L (17.8%). The test–retest reliability and convergent validity of the 5L were slightly better than those of the 3L. Both the 3L and 5L showed known-group validity; however, the 5L index showed better discriminatory power. Similar trends were found in the six types of cancers. In general, 5L appears to have better measurement properties than 3L for measuring the health-related quality of life of cancer patients. While both the 3L and 5L are suitable, 5L should be preferable to 3L for use in cancer outcomes research.
