BACKGROUND In order to estimate utilities for cancer studies where the EQ-5D was not used, the EORTC QLQ-C30 can be used to estimate EQ-5D using existing mapping algorithms. Several mapping algorithms exist for this transformation, however, algorithms tend to lose accuracy in patients in poor health states. The aim of this study was to test all existing mapping algorithms of QLQ-C30 onto EQ-5D,...

OBJECTIVE To assess the practicality, validity and responsiveness of using each of two utility measures (the EQ-5D and SF-6D) to measure the benefits of alleviating knee pain. METHODS Participants in a randomised controlled trial, which was designed to compare four different interventions for people with self-reported knee pain, were asked to complete the EQ-5D, SF-6D, and Western Ontario and...

OBJECTIVE To assess the longitudinal validity of widely used preference-weighted measurement systems for economic studies of intervertebral disk herniation (IDH). METHODS Using data at baseline and 1 year from 1000 Spine Patient Outcomes Research Trial (SPORT) participants with IDH and complete data, the authors considered the EQ-5D with UK and US values (EQ-5D-UK and EQ-5D-US), 2 versions of...

BACKGROUND Although exposure to second-hand smoke (SHS) has been associated with various medical conditions, only limited data are available on its association with health-related quality of life (HRQOL), particularly data obtained with the EQ-5D or EQ visual analogue scale (VAS). METHODS This cross-sectional study evaluated 10,532 adult never-smokers who participated in the fifth Korea Natio...

Systematic literature searches were conducted to identify studies that conducted statistical mapping to predict EQ-5D utilities or responses from any source instrument and reported the estimated algorithms in sufficient detail to allow other researchers to use them to predict EQ-5D in other studies. Ninety studies reporting 121 mapping algorithms met the inclusion criteria. The studies estimate...

OBJECTIVE Health-related quality of life (HRQoL) in patients with systemic sclerosis (SSc), a chronic disabling disease associated to physical and psychological impairment, is often left behind in clinical practice and research. This is due to the use of tools that are not complete or mainly designed for the physical condition only. We tested EQ-5D, a valid, simple and brief questionnaire for H...

BACKGROUND The EuroQoL 5D (EQ-5D) is a questionnaire that provides a measure of utility for cost-effectiveness analysis. The EQ-5D has been widely used in many patient groups, including those with coronary heart disease. Studies often require patients to complete many questionnaires and the EQ-5D may not be gathered. This study aimed to assess whether demographic and clinical outcome variables,...

background health-related quality of life (hrqol) is used as a measure to valuate healthcare interventions and guide policy making. the euroqol eq-5d is a widely used generic preference-based instrument to measure health-related quality of life. objectives the objective of this study was to develop a value set of the eq-5d health states for an iranian population. patients and methods this study...

The objective of this study was to evaluate the quality of life (QOL) of patients with deep infiltrating endometriosis (DIE) using EuroQOL (EQ-5D) and its correlation with symptoms and locations of endometriotic lesions. One hundred and fifty-nine patients referred for DIE from January 2011 to April 2011 were prospectively invited to complete questionnaires evaluating symptoms associated with e...
