Population norms of health-related quality of life in Moscow, Russia: the EQ-5D-5L-based survey

Abstract

Purpose To develop population norms for the EQ-5D-5L questionnaire based on a representative sample of Moscow citizens. Methods We used quota sampling accounting for sex, age group and administrative district of residence. Respondents in randomly selected outdoor and indoor locations were surveyed with the official Russian paper-and-pencil version of the EQ-5D-5L questionnaire and a set of socio-demographic questions. We estimated four types of EQ-5D results: the distribution of limitations according to EQ-5D-5L dimensions, the perception of the health-related quality of life (HRQoL) with a visual analogue scale (EQ VAS), the unweighted score for a respondent’s health state (Level Sum Score, LSS) and the Russian health preferences-based weighted score (EQ index). In order to estimate the EQ-5D-5L index, we used a newly developed Russian EQ-5D-3L value set, together with EuroQol Group cross-over methodology. Results A total of 1020 respondents (18–93 years old) from the general Moscow adult population completed the EQ-5D-5L questionnaire. HRQoL domains with the largest number of identified health limitations were pain/discomfort (48.6%) and anxiety/depression (44.1%). Two hundred seventy-nine respondents (27.0%) did not report any health restrictions. The mean EQ VAS and EQ-5D-5L index were 74.1 (SD 17.3) and 0.907 (0.106) respectively. Multivariate analysis showed that female sex, advanced age and lack of access to the Internet had a negative influence on HRQoL, whereas residence in certain districts had a positive impact. Conclusions The study provides population norms of health-related quality of life in Moscow, measured according to the EQ-5D-5L questionnaire. These reference values can be used to optimise the effectiveness of resource allocation in healthcare.

Inequality and heterogeneity in health-related quality of life: findings based on a large sample of cross-sectional EQ-5D-5L data from the Swedish general population

“…Population reference data for the EQ-5D-5L are available for several countries at national or regional level. Recently, data have been presented for United States [ 15 ], Canada [ 16 ], Bulgaria [ 17 ], Russia [ 18 ], and Slovenia [ 19 ], adding to previous data for China [ 20 ], Germany [ 21 – 23 ], Indonesia [ 24 ], Ireland [ 25 ], South Australia [ 26 ], Spain [ 27 , 28 ], Trinidad and Tobago [ 29 ], and Uruguay [ 30 ].…”

Health-Related Quality of Life Norm Data of the Peruvian Adolescents: Results Using the EQ-5D-Y

“…There are numerous publications on the normative data of the EQ-5D-5L and EQ-5D-3L questionnaire among adults in European countries such as Spain [9], Denmark [10], Germany [11], Portugal [12], and United Kingdom [13]. In another continents, there are publications in Japan [14], Australia [15], Hong-Kong [16], and Russia [17]. However, the establishment of normative values in children/adolescents has only been published in Japan [18].…”

Development of an EQ-5D Value Set for India Using an Extended Design (DEVINE) Study: The Indian 5-Level Version EQ-5D Value Set

“…This is in contrast with most of the previous studies aimed at generating country-level EQ-5D-5L value sets, which pursued purposive or quota sampling. 26,[35][36][37][38] Using such a rigorous sampling approach has averted the potential issues related to purposive or quota sampling, such as (1) the chances of missing out respondents who clearly do not fall into any of the quota groups and (2) the nonrandom selection of respondents. Moreover, an iterative QC approach was used to obtain highquality data.…”
