Comparison of two utility instruments, the EQ-5D and the 15D, in the critical care setting.

ABSTRACT:

Purpose

Reliable measures are required for proper cost-utility analysis after critical care. No gold standard is available, but the EQ-5D health-related quality of life instrument (HRQoL) has been proposed. Our aim was to compare the EQ-5D with another utility measure, the 15D, after critical illness.

Methods

A total of 929 patients filled in both the EQ-5D and 15D HRQoL instruments 6 and 12 months after treatment at an intensive care or high-dependency unit. The difference in the medians and distributions of the scores of the instruments was tested with Wilcoxon signed-rank test and their association with Spearman rank correlation. Discriminatory power was compared by the ceiling effect and agreement between the instruments regarding the direction of the minimal clinically
