1. What is the EQ-5D-5L Crosswalk Index?

The EQ-5D-5L is a standardized instrument for measuring health-related quality of life. The crosswalk index value provides a single summary index by mapping 5-level responses to the 3-level value set using specific weighting coefficients.

2. How Does the Calculator Work?

The calculator uses the EQ-5D-5L crosswalk formula:

\[ Index = \sum (Dimension\ Scores \times Weights) \]

Where:

Dimension Scores — Health state levels (1-5) across five dimensions
Weights — Country-specific value set coefficients

Explanation: The equation calculates a weighted sum of the five dimension scores to produce a single index value representing overall health-related quality of life.

3. Importance of EQ-5D-5L Assessment

Details: The EQ-5D-5L index is widely used in clinical studies, health economic evaluations, and population health surveys to measure and compare health outcomes across different populations and interventions.

4. Using the Calculator

Tips: Select the appropriate level (1-5) for each of the five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Level 1 indicates no problems, level 5 indicates extreme problems.

5. Frequently Asked Questions (FAQ)

Q1: What do the different levels mean?
A: Level 1: No problems, Level 2: Slight problems, Level 3: Moderate problems, Level 4: Severe problems, Level 5: Extreme problems/unable to

Q2: Are the weights country-specific?
A: Yes, different countries have different value sets. This calculator uses example weights - consult local guidelines for appropriate coefficients.

Q3: What is a normal index value?
A: Values typically range from below 0 (worse than dead) to 1 (perfect health), with 1 representing the best possible health state.

Q4: How often should EQ-5D-5L be assessed?
A: Frequency depends on the clinical context - typically at baseline and follow-up visits to monitor changes in health-related quality of life.

Q5: Can this be used for economic evaluations?
A: Yes, the index values are commonly used in cost-utility analyses to calculate quality-adjusted life years (QALYs).
