OBJECTIVES: To clarify the difference between the interim EQ-5D-5L score and EQ-5D-5L Japanese scoring, and to evaluate the validity of them. METHODS: Five hundred and twenty six patients who received rehabilitation program in six hospitals were asked to administer the EQ-5D-5L. Their occupational therapists were simultaneously administered the EQ-5D-5L as proxy respondents to assess their health-related quality of life (HRQL). The score of the EQ-5D-5L were calculated by the interim value set and new Japanese scoring algorism. The new algorism used TTO model was developed by Japanese EQ-5D team as the national tariff. Pearson’s correlations were used to evaluate the concurrent validity of the EQ-5D-5L. RESULTS: Mean age of the patients was 67.1 years. Three hundred and twenty one were male (60.1%). The mean scores of the interim EQ-5D-5L score and Japanese scoring were 0.515 (95%CI; 0.493-0.538) and 0.547 (95%CI; 0.526-0.567), respectively. Significantly results in two tariffs were observed by the modified Rankin scale (mRS) in: mRS1 (0.805 vs 0.850), mRS2 (0.682 vs 0.729), mRS3 (0.604 vs 0.618), mRS4 (0.400 vs 0.410), mRS5 (0.081 vs 0.201). In particular, the strong difference was observed in 5 level of the modified Rankin scale (0.081 vs 0.201). The correlation between the interim score and new Japanese scoring was 0.946. CONCLUSIONS: The new Japanese tariff for EQ-5D-5L indicated high validity, but had a few differences with the interim value. We have to mind the differences when use it.
