ABSTRACT
Objective: The EQ-5D-5L is increasingly used in cardiovascular surgery. However, its psychometric properties have not yet been examined with coronary artery bypass graft patients. The purpose of the study was to assess the psychometric properties of the EQ-5D- 5L with coronary artery bypass graft patients and to determine the most suitable index score for the countries with no value set.

Material and Method: The EQ-5D-5L was administered to 200 coronary artery bypass graft patients. Intraclass correlation coefficients and test-retest analysis were used to evaluate the reliability of the scale. The test-retest analysis used Gwet’s agreement coefficient.

Results: The intraclass correlation coefficients indicated that the EQL-VAS and index scores were very reliable. The five dimensions of the EQ-5D-5L had an almost perfect agreement with the test-retest (Gwet’s AC: 0.83-0.97, percentage agreement: 89.6-97.6%). Both the United Kingdom and United States index scores had a positive and moderate relationship with the EQL-VAS (p<0.001).

Conclusion: The EQ-5D-5L is a reliable and practical instrument in cardiovascular surgery. This study showed that both United Kingdom and United States value sets can be used to calculate the index score of the scale in Türkiye.
