This is the third of a series of PROMs special topics produced on a quarterly basis. The data presented is based on 2009-10, the most current version of finalised data. Further details concerning these data sets can be found via the links on the left-hand side.
The EQ-5D system used in PROMs provides two measures of general pre- and post-operative health, the EQ-5D Descriptive System and EQ visual analogue scale (EQ-VAS). This quarterly Topic of Interest aims to provide users of the PROMs data with an understanding of the changes in the individual components of the EQ-5D descriptive system score between the pre- and post-operative questionnaires.
The EQ-5D Descriptive System of health-related quality of life states consists of five dimensions - mobility, self-care, usual activities, pain/discomfort and anxiety/depression - each of which can take one of three responses. The responses record three levels of severity - no problems/some or moderate problems/extreme problems - within a particular EQ-5D dimension. In the standard publication these five states are combined using weights to give a single headline index measure which ranges from -0.594 to 1, where 1 is the best possible state of health. However this topic paper focuses on the components prior to conversion into an index. Further information regarding the EQ-5D system can be found on the EuroQol Group website.
The 'Key Facts' summarise the national level changes in the five EQ-5D index score components whilst the supporting spread sheet allows users to split the components by various dimensions at national level or view components for a chosen organisation.
