CHU9D (Child Health Utility 9D)
The CHU9D is a questionnaire designed to measure health-related quality of life in children and teenagers. It helps calculate quality-adjusted life years (QALYs) by capturing how health affects their daily life, using values provided by adults to assess child health states.
At a glance
Use when
Evaluating interventions targeting children where QALYs are required, especially in economic evaluations within public health or paediatric care.
Avoid when
When child-preferred utility values are essential, or when using in populations below age 7 where comprehension may be limited.
Inputs
Responses from children or adolescents (typically aged 7–17) to the 9-item CHU9D questionnaire.
Outputs
Health state utility values (HSUVs) for calculating QALYs in economic models and evaluations.
How it works
The CHU9D is a generic, preference-based instrument developed specifically for paediatric populations to enable QALY calculation in economic evaluations. It consists of nine dimensions, each with five levels, and uses an adult-elicited value set to derive utility scores for child health states.
- HTA domains
- Patient and Social Aspects
- Categories
- HRQoL
- Assumptions
- Adult-derived utility values appropriately reflect societal preferences for child health states; self-reported child responses are valid and reliable.
- Strengths
- Designed specifically for children; self-completion format suitable for young populations; enables QALY estimation in paediatric cost-utility analyses.
- Limitations
- Utility values are based on adult preferences, not children's own valuations; limited sensitivity in certain populations or conditions.
