The purposes of this study were to measure health related quality of life (HRQOL) of persons disabled by stroke dwelling in Gyeongju-si using EQ-5D and to estimate total QALYs loss of persons disabled by stroke in Korea.
The eligible subjects were 982 persons with stroke aged 50 and over in Gyeongju-si disabled registry, as of March, 2008. Interviewers measured HRQOL of study subjects using EQ-5D. EQ-5D index, utility weight, was derived from the Korean valuation set. In order to compare the results of this study, we selected two comparison groups representing Korean healthy population and general population of Korean using the 4th Korean National Health & Nutrition Examination Survey. Finally, after age and gender standardization, we estimated the total QALYs losses of persons disabled by stroke in Korea.
Of 982 eligible subjects, 566 persons participated in the survey (response rate: 57.6%). In both of female and male, utility weights in the 70s or 80s were lower than those of the 50s or 60s. Utility weights differences among persons with disability, general population, and healthy population in male were larger than those differences in female. Total estimated QALY losses of persons disabled by stroke were 67,011.6 QALYs lower than healthy control group and 54,167.1 QALYs lower than general population, respectively.
