“…Each health state can be converted to a composite utility (preference) score from 0 (death) to 1 (perfect health), with a scoring algorithm derived from population-based valuation. The Chinese-Traditional (Hong Kong) translation of the EQ-5D-5L and the Hong Kong population specific EQ-5D-5L value set have been developed and normed on the local population [ 6 , 8 ]. The EuroQol Group full version of EQ-5D-5L (Web version)—Chinese-Traditional (Hong Kong) was adapted for electronic administration.…”

Background Electronic measurement of health-related quality of life (HRQOL) may facilitate timely and regular assessments in routine clinical practice. This study evaluated the validity and psychometric properties of an electronic version of the EQ-5D-5L (e-EQ-5D-5L) in Chinese patients with chronic knee and/or back problems. Methods 151 Chinese subjects completed an electronic version of the Chinese (Hong Kong) EQ-5D-5L when they attended a primary care or orthopedics specialist out-patient clinic in Hong Kong. They also completed the Chinese Western Ontario and McMaster University Osteoarthritis Index (WOMAC), a Pain Rating Scale, and a structured questionnaire on socio-demographics, co-morbidities and health service utilization. 32 subjects repeated the e-EQ-5D-5L two weeks after the baseline. 102 subjects completed e-EQ-5D-5L and 99 completed the Global Rating on Change Scale at three-month clinic follow up. Construct validity was assessed by the association of EQ-5D-5L scores with external criterion of WOMAC scores. We tested mean differences of WOMAC scores between adjacent response levels of the EQ-5D-5L dimensions by one-way ANOVA, test–retest reliability by intra-class correlation, sensitivity by known group comparisons and responsiveness by changes in EQ-5D-5L scores over 3 months. Results There was an association between EQ-5D-5L and WOMAC scores. Mean WOMAC scores increased with the increase in adjacent response levels of EQ-5D-5L dimensions. Test–retest intraclass correlation coefficient (ICC) of EQ-5D-5L utility and EQ-VAS scores were 0.76 and 0.83, respectively, indicating good reliability. There were significant differences in the proportions reporting limitations in the EQ-5D-5L dimensions, the utility and VAS scores between the mild and severe pain groups (utility = 0.28, p = 0.001; VAS = 11.46, p < 0.001), and between primary care and specialist out-patient clinic patients (utility = 0.15, p = 0.001; VAS = 10.21, p < 0.001), supporting sensitivity. Among those reporting ‘better’ global health at three-months, their EQ-5D-5L utility and EQ-VAS scores were significantly increased from baseline (utility = 0.18, p < 0.001; VAS = 10.75, p = 0.005). Conclusions The electronic version of the EQ-5D-5L is valid, reliable, sensitive and responsive in the measurement of HRQOL in Chinese patients with chronic knee or back pain in routine clinical practice.

“…39 To gather a proactive collection of feedback from patients with different disease and health needs, the patient experience survey on specialist outpatient and accident and emergency services was followed in 2014 40 and 2016, 41 respectively. The collection of self-reported health statuses using the validated Chinese version of the EQ-5D-5L (EQ-5D-5L HK), 42 therefore, enables measurement of HRQoL among patients with chronic diseases 43 and correlations with patient engagement in hospital settings. 44 Nevertheless, to date, there is only one published article mentioning population norms for the HK Chinese population using the SF-6D instrument.…”

Valuation of Health States Considered to Be Worse Than Death—An Analysis of Composite Time Trade-Off Data From 5 EQ-5D-5L Valuation Studies

To evaluate the discriminative ability of negative values measured in 5-level EuroQol 5-dimensional questionnaire (EQ-5D-5L) value set studies. Methods: This is a secondary analysis of EQ-5D-5L value set studies from Singapore, the Netherlands, China, Thailand, and Canada in which health state values were elicited from a general population sample using a composite time trade-off (TTO) method. Mean values were calculated for health states with same severity. The association between the mean values and severity was evaluated using Pearson correlation (r). A linear mixed model using severity as the fixed effect was fitted for values. The analyses were performed separately for positive values (from a conventional TTO for health states considered "better than death") and negative values (from a lead time TTO for health states considered "worse than death"). Results: In Singapore (N ¼ 1000; negative values 32.6%), the mean decreased with severity from 0.89 to 0.21 for positive values and increased with severity from À0.98 to À0.89 for negative values. The correlation between values and severity was much lower for negative values (r ¼ À0.016) than for positive values (r ¼ À0.614). The coefficient of severity in the linear mixed model for negative values was much smaller (coefficient ¼ À0.009; pseudo-R 2 < 0.001) compared with the model for positive values (coefficient ¼ À0.041; pseudo-R 2 ¼ 0.337). Results using data sets from the other countries were similar. Conclusions: Negative values are not associated with severity of health states in EQ-5D-5L valuation studies, suggesting poor discriminative ability of the lead time TTO method in valuing health states considered worse than death.
