The health status of 69 survivors of high-risk acute lymphoblastic leukaemia (ALL) is assessed using a multi-attribute classification system. Seven attributes are included: sensation, mobility, emotion, cognition, self-care, pain and fertility. Three to five levels of functioning are defined for each attribute. Comprehensive health states are described as a specific combination of seven attribute levels. The system captures combinations of sequelae. The system provides a compact but comprehensive tool for long term follow up of survivors of childhood cancer. The results underscore the cognitive and emotional burdens of morbidity affecting survivors of high-risk ALL.
