Supplementary Material - Objectives
Very limited previous research has investigated the utility weights of prostate-related diseases in the general population in Korea. The purpose of this study was to calculate the utility of prostate-related health states in the Korean general public using the standard gamble (SG) method.
Methods
Seven health states for hypothetical prostate cancers, 1 for benign prostate hyperplasia, and 1 for erectile dysfunction were developed based on patient education material and previous publications. In total, 460 responses from the Korean general population were used to analyze the utility of prostate-related health states. Computer-assisted personal interviews were conducted, and utility values were measured using a visual analogue scale (VAS) and SG. Mean utility values were calculated for each prostate-related health state.
Results
The mean utility values of prostate cancer derived from SG ranged from 0.281 (metastatic castration-refractory prostate cancer) to 0.779 (localized prostate cancer requiring prostatectomy). The utility value of benign prostate hyperplasia was 0.871, and that of erectile dysfunction was 0.812. The utility values obtained using the SG method in all conditions were higher than the values obtained by VAS. There were no significant demographic variables affecting utility values in multivariate analysis.
Conclusions
Our findings might be useful for economic evaluation and utility calculation of screening and interventions for prostate-related conditions in the general population. -

이 연구는 일반인구집단을 대상으로 7개의 전립선 암 상태와 전립선 비대증, 발기부전상태의 효용값을 표준기회선택법을 이용하여 산출하였다. 전립선암 상태에 따라 평균 효용값은 0.281에서 0.779범위였다. 연구 결과는 전립선 관련 상태의 중재의 효용 계산이나 경제성 평가에 활용할 수 있을 것이다.
