Valuation of Child Health-Related Quality of Life in the United States.

Many economic analyses fail to incorporate evidence on child health-related quality of life because of a paucity of quality-adjusted life year (QALY) estimates. This health valuation study is the first to summarize the EQ-5D-Y on a QALY scale. Drawn from a nationally representative panel, 5207 adult respondents were asked to choose between two losses in child health-related quality of life. Based on their choices, a 1-year increase in child pain/discomfort from 'some' to 'a lot' equals a loss of 4 QALYs (95% CI, 3.8-4.4). Likewise, a 1-year increase in child anxiety/depression from 'a bit' to 'very worried, sad, or unhappy' equals a loss of 2 QALYs (95% CI, 1.9-2.2). These findings enable the integration of child-reported outcomes with adult preferences to inform economic analysis. Results inform both clinical practice and resource allocation decisions by enhancing understanding of difficult tradeoffs in child-reported outcomes.
