Validity of EQ5D-5L and other measures for over-65s

Assessment of the EQ-5D-5L compared to EQ-5D-3L and generation of population norms in England

Comparing EQ-5D-5L and EQ-5D-3L data in the United Kingdom using the GP Patient Survey (GPPS). The study will also generate population norm data for the EQ-5D-5L. EQ-5D-5L was developed to address concerns with the discriminative properties of EQ-5D-3L. Results will add to the growing body of knowledge on the performance of EQ-5D-5L as well as population norm data that can be used by researchers in the UK.

Formal and informal social care support is an important input for individuals with long term conditions (LTCs) as they can help maintain well-being even where health is not improving. Health related quality of life measures such as EQ-5D may capture some of the impact of social care but may miss out on aspects such as independence and control and new measures such as the ICECAP-O, ASCOT or well-being have been recommended as alternatives.

The overall aim of this study was to compare the new 5 level version of EQ-5D to these new ‘beyond health measures’ in a longitudinal study in order to examine the extent to which EQ-5D already captures the ‘beyond health’ domains covered in these measures. LTCs are more prevalent in older populations therefore participants aged over 65 with and without LTCs were recruited from the South Yorkshire Cohort in 2014 (n=1749) with follow-up in 2015/16 (n=1213).
