Health utility measured with EQ-5D in Thai patients undergoing peritoneal dialysis.

To measure health utility by using the EuroQol five-dimensional questionnaire (EQ-5D) in Thai patients undergoing peritoneal dialysis (PD) and to examine the relationship between the EQ-5D and patient characteristics including sociodemographic and clinical data and end-stage renal disease symptoms. This was a cross-sectional study. About 10 to 12 patients undergoing PD were randomly selected from each of the 10 hospitals located in every part of Thailand. Face-to-face interviews were conducted from October 2008 to February 2009. Patients assessed their health status by using five domains and a visual analogue scale. The EQ-5D score was calculated on the basis of responses to five domains by using the Thai value set. Multiple regression analyses using a stepwise method were employed to model the associations between the EQ-5D score, the VAS score, and patient characteristics. The patients' mean age was 42.2 ± 13.8 years; 53% were male. The mean PD duration was 7.4 ± 6.0 months. The mean EQ-5D and visual analogue scale scores were 0.65 ± 0.23 and 0.65 ± 0.26, respectively. The EQ-5D score was higher than that obtained from a meta-analysis study (0.58). The multivariate regression model showed that education, work status, diabetes, and end-stage renal disease symptoms were significant predictors of the EQ-5D score. The significant predictors of the VAS score included work status, albumin level, use of erythropoietin, and end-stage renal disease symptoms. This Thai PD sample yielded higher EQ-5D scores than did other PD populations. To improve the health utility of Thai patients undergoing PD, the significant factors should be addressed. Because our PD sample had a short PD duration, their long-term health utility should be evaluated in future research.

Comparison of EQ-5D-5L, VAS, and SF-6D in Thai Patients on Peritoneal Dialysis.

To compare the utility scores derived from the 5-level EuroQol 5-dimensional questionnaire (EQ-5D-5L), the visual analogue scale (VAS), and the 6-dimensional health state short form (SF-6D) in Thai patients on peritoneal dialysis. Data were obtained from the 36-Item Kidney Disease Quality of Life questionnaire and the EuroQol questionnaires (EQ-5D-5L and VAS) via face-to-face interview for 64 patients on peritoneal dialysis. We compared the ceiling effect of all the utility tools by calculating the proportion at the highest scores. The mean difference in utility scores defined by patients' demographic characteristics and clinical laboratory value was evaluated using independent t tests or the Mann-Whitney U test. Moreover, the correlation was assessed using the Pearson correlation coefficient. The agreements among the instruments were illustrated with the Bland and Altman plots. The mean score of the EQ-5D-5L, SF-6D, and VAS were 0.801, 0.784, and 0.733, respectively. The EQ-5D-5L presented a higher percentage of the ceiling effect than did the SF-6D and VAS. The EQ-5D-5L was able to distinguish the mean difference between age groups with significant difference (P<.001). The Pearson correlation coefficients between utility scores and the 3 dimensions of the 36-Item Kidney Disease Quality of Life questionnaire had a significantly positive correlation, especially for the SF-6D. The Bland and Altman plots portrayed that the utility scores from the EQ-5D-5L were lower than those from the SF-6D and VAS among the patients in the poorer health state. Among the SF-6D, EQ-5D-5L, and VAS, only the EQ-5D-5L could distinguish the utility scores between different age groups. Nevertheless, the EQ-5D-5L presented the ceiling effect, whereas there was no evidence of the ceiling effect for the SF-6D. The SF-6D presented better correlation with the kidney disease-specific dimensions than did the EQ-5D-5L and VAS. Thus, the advantages and disadvantages of each utility tool should be considered.
