A value set for the EuroQoL 5-Dimensions (EQ-5D)-Y in Slovenia is not yet available, making the calculation of quality-adjusted life-years (QALYs) for children and adolescents using this generic instrument impossible.
The main objective of our study was to obtain adult preferences towards EQ-5D-Y health states in Slovenia, following the EQ-5D-Y-3L international valuation protocol. The adults were asked to take the perspective of a hypothetical 10-year-old child.
A sample of 1074 adults in Slovenia completed an online discrete-choice experiment (DCE) survey on EQ-5D-Y health states. The latent scale issue was addressed by obtaining the value of the anchor (33333) with 200 composite time trade-off (cTTO) interviews. A mixed (random coefficients) logit model was used to estimate the value set.
All the estimated coefficients of the mixed logit model were statistically significant at the 1% level and had an expected negative sign. The most important health dimension in EQ-5D-Y is pain/discomfort, followed by anxiety/depression, usual activities, and mobility, with self-care being the least important health dimension.
The study addresses an important research gap and presents the EQ-5D-Y value set for Slovenia. At the time of writing, no published value sets are available for the EQ-5D-Y-3L appropriate for use in QALY calculations, making this value set the first EQ-5D-Y value set in the world.
斯洛文尼亚尚未制定欧洲五维健康量表简表(EQ-5D-Y)的价值量表,因此无法使用该通用量表计算儿童和青少年的质量调整生命年(QALY)。
本研究的主要目的是根据 EQ-5D-Y-3L 国际估值方案,获取斯洛文尼亚成年人对 EQ-5D-Y 健康状况的偏好。要求成年人从一个假设的 10 岁儿童的角度来考虑。
斯洛文尼亚的 1074 名成年人完成了一项关于 EQ-5D-Y 健康状况的在线离散选择实验(DCE)调查。通过对 200 个复合时间权衡(cTTO)访谈获得锚定值(33333)来解决潜在量表问题。采用混合(随机系数)对数模型来估计价值量表。
混合对数模型的所有估计系数在 1%水平上均具有统计学意义,且具有预期的负号。EQ-5D-Y 中最重要的健康维度是疼痛/不适,其次是焦虑/抑郁、日常活动和移动性,自我护理是最不重要的健康维度。
该研究解决了一个重要的研究空白,并提出了斯洛文尼亚的 EQ-5D-Y 价值量表。在撰写本文时,尚无适合用于 QALY 计算的已发表的 EQ-5D-Y-3L 价值量表,因此该价值量表是世界上第一个 EQ-5D-Y 价值量表。
