Objectives : The aim of this study was to determine the cost effectiveness for BMD measurement tools to health examination in transitional ages, comparing RA, QUS, pDXA, QCT and standard equipments, DXA of adult Korean aged 66 years or older.
Materials and Methods : A total of 101 subjects aged in 60s’ were recruited for this study. A Markov model was developed to analyze the cost-effectiveness of DXA, QUS, RA, pDXA,and QCT. A cohort of 10,000 women aged 66 who were the target population of lifetime bone densitometry exam was constructed for each bone densitometry of DXA, QUS, RA, pDXA, and QCT and a cohort of 10,000 women aged 66 was also constructed as a non-exam group. In the Markov model of osteoporosis and its related fractures, costs and effectiveness measured by QALY were estimated until the cohorts reached 100 years old or died.
Results : Cost-effectiveness can, first, be presented by cost-effectiveness ratio (CER). The results showed that non-exam group had the lowest CER., Cost-effectiveness can also be presented by incremental cost-effectiveness ratio (ICER). ICER is meaningful as an indicator of how much extra costs are needed to increase an extra 1 QALY compared to the reference group. When the non-exam group was set to be the reference group, the magnitudes of ICER;s were ordered as DXA
