Multi-attribute health status classification systems. Health Utilities Index

Area of Science:

• Health outcomes research
• Psychometrics
• Public health

Background:

• Assessing health status is crucial for population health and program evaluation.
• Multi-attribute systems offer a comprehensive framework for health status description.
• The Health Utilities Index (HUI) systems are prominent examples of such approaches.

Purpose of the Study:

• To review multi-attribute approaches for health status assessment.
• To focus on the recently developed Health Utilities Index (HUI) Mark II and Mark III systems.
• To highlight the attributes and scoring capabilities of these HUI systems.

Main Methods:

• Review of multi-attribute health status assessment systems.
• Detailed examination of the Health Utilities Index (HUI) Mark II and Mark III systems.
• Analysis of the attributes and levels comprising health states within the HUI framework.

Main Results:

• The HUI Mark II system includes 7 attributes: sensation, mobility, emotion, cognition, self-care, pain, and fertility.
• The HUI Mark III system includes 8 attributes: vision, hearing, speech, ambulation, dexterity, emotion, cognition, and pain.
• Both systems provide a pure description of health status, independent of opportunity or preference.

Conclusions:

• Multi-attribute systems like the HUI provide a compact yet comprehensive method for describing health status.
• These systems allow for detailed attribute-by-attribute analysis and capture of combined deficits.
• Compatibility with multi-attribute preference functions enables computation of summary health-related quality-of-life scores.
