The Irish EQ-5D-5L Survey, 2015-2016

Study number (SN): 0060-00

ABOUT THE STUDY

Data were collected for 1311 individuals in the Republic of Ireland between March 2015 and September 2016 using the EQ5D5L descriptive framework. The survey included the collection of self-reported health status across five domains of health - mobility, self-care, usual activities, pain/discomfort and anxiety/depression - at five levels of severity. In addition, a broad range of socio-demograpic data including age, gender, martial status, income, education and urban/rural location were collected. Data from the survey has been used to establish population norms for health using the EQ5D5L descriptive framework for Ireland (i.e. representative values of the resident population) and to examine variations in these beween groups differentiated by observed socio-demograpic characteristics. The data allows researchers to compare Irish norms with that of samples they may have generated or can access from other studies using the same instrument and to explore the sources of variations among and beween. This is the first national set of EQ-5D-5L data for Ireland.

Sampling procedures

A representative sample off Irish residents was drawn using a two-stage stratified clustering process as detailed by Haase and Pratschke, (2012). In the first stage, a sample of 54 small areas stratified by deprivation level and urban/rural classifications were drawn at random from across the country. In the second stage, within each small area, a sample of approximately 20 houses were selected at random. Random selection was achieved by using a random starting point and inviting a resident in every third house to participate in the survey. To achieve this, each house was visited up to three times throughout the day (and evening) in an effort to make contact with the householder. Where it was not possible to elicit a response from the selected house, it was replaced from among those in the immediate vicinity, generally based on immediate physical proximity. Within each house any adult capable of giving informed consent could volunteer to complete the survey, one volunteer per household being chosen at random.

Purposive sampling to augment the number of younger persons and males in the sample was undertaken in 2016. This followed a comparison of the recruited sample with that of the CSO population estimates for age and gender nationally. 102 of the 1131 completed surveys were purposive.

Response rate

Excluding the purposive sample and properties where it was not possible, despite call backs, to contact the householder, the response rate of the survey was 47%. Including properties where contact with the householder was not possible in the denominator, the response rate was 19%.
