Understanding the EQ-5D-5L Questionnaire
What is the EQ-5D-5L?
The EQ-5D-5L is a standardized instrument developed by the EuroQol Group designed to measure health-related quality of life. It captures an individual’s self-reported health across five dimensions, each with five levels of severity. The 5L version improves upon the earlier 3-level version by providing more nuanced data, reducing ceiling effects, and enhancing sensitivity.
Purpose and Uses
The primary purpose of the EQ-5D-5L questionnaire is to:
- Assess patients’ health status in clinical settings
- Collect data for health economics and outcomes research
- Support decision-making in healthcare policy
- Monitor health outcomes over time in longitudinal studies
- Facilitate cost-utility analysis by generating quality-adjusted life years (QALYs)
The availability of the questionnaire in PDF format makes it accessible for clinicians and researchers to incorporate into various settings, whether printed for patient completion or integrated into electronic health records.
Structure of the EQ-5D-5L Questionnaire PDF
Five Dimensions of Health
The questionnaire evaluates five key dimensions:
