Value Frameworks: Adaptation of Korean Versions of Value Frameworks for Oncology

초록

This study sought to adapt the existing value framework (VF) to produce a reliable and valid Korean oncology VF. Two VFs developed by The American Society of Clinical Oncology (ASCO) and the European Society for Medical Oncology (ESMO) were selected for examination in the present study. Forward and backward translations were conducted for six high-priced drugs indicated for non-small-cell lung cancer and multiple myeloma. Inter-rater reliability was measured based on the intraclass correlation coefficient (ICC) and variation was described using the coefficient of variation. The relative weights of factors critically considered by Korean oncologists were derived following the analytic hierarchy process (AHP), and focus group interviews (FGIs) were used to obtain qualitative data regarding the applications of these two VFs in the Korean setting. The ICCs of the Korean VFs were 0.895 (0.654-0.983) for ASCO and 0.726 (0-0.982) for ESMO translations, suggesting excellent reliability for ASCO and good reliability for ESMO. AHP demonstrated that clinical benefit has the highest priority, which is consistent with the ASCO VF. The FGIs suggested that the result for AHP is acceptable and that both ESMO and ASCO VFs should be used complementarily. Although further evaluation with a larger sample size is needed, the Korean versions of ESMO/ASCO VFs are valid and reliable tools and are acceptable to Korean stakeholders, yet they should be applied with caution.
