Health-related quality of life (HRQL) is a relevant outcome measures in intensive care unit (ICU). The aim of this study was to evaluate HRQL of ICU patients 3 months after discharge using the Arabic version for Morocco of the EuroQol-5-Dimension (EQ-5D), and to examine the psychometric properties of the questionnaire.
Results: The Arabic version for Morocco of the EQ-5D was approved by the EuroQol group.
A prospective cohort study was conducted after medical ICU discharge. At 3-month follow up, the EQ-5D (self classifier and EQ-VAS) was administered in consultation or by telephone.
EQ-VAS varies from 0 (better HRQL) to 100 (worst HRQL). An unweighted scoring for EQ5D-index was calculated.
EQ5D-index ranges from 0.59 to 1. Test-retest reliability of the EQ-5D was tested using Kappa coefficient and intraclass correlation coefficient (ICC).
Criterion validity was assessed by correlating EQ-VAS and EQ5D-index with the Short Form 36 (SF-36). Construct validity was tested using simple and multiple liner regression to assess factors influencing patients’HRQL.
145 survivors answered the EQ-5D. Median EQ5D-index was 0.52 [0.20-1].
Mean EQ-VAS was 62 +/- 20. Test-retest reliability was conducted in 83 patients.
ICCs of EQ5D-index and EQ-VAS were 0.95 and 0.92 respectively. For EQ-5D self classifier, agreement by kappa was above 0.40.
Significant correlations were noted between EQ5D-index, EQ-VAS and SF-36 (p <0.001). In multivariate analysis, factors associated with poorer HRQL for EQ5D-index were longer ICU length of stay (beta = 0.01; p = 0.017) and higher educational level (beta = 0.2; p = 0.001).
For EQ-VAS men were associated with better HRQL (beta = 6.5; p = 0.048).
Conclusions: The Arabic version for Morocco of the EQ-5D is reliable and valid. Women, high educational level and longer ICU length of stay were associated with poorer HRQL.
