Documentation:: Database of studies mapping to EQ-5D from other patient-reported outcome measures or clinical instruments. The database presents details of the sample size, modelling methods and patient population, in addition to the citation details and source instruments that are mapped in each of the 182 studies meeting the inclusion criteria. An article summarising the methods of the literature review and the results for version 6.0 has been published in Health and Quality of Life Outcomes, updating the older article on version 2.0 of the database. The current version (7.0) is based on searches conducted in January 2019; the database will be updated approximately annually as new studies are published. The database aims to provide a readily-accessible collection of all studies mapping to EQ-5D that is easy to search and filter. We anticipate that this will be useful for: ◾Those who wish to identify mapping studies to estimate utilities for cost-utility analyses and/or decision-analytical models constructed for publication or for submissions to health technology assessment (HTA) organisations, such as NICE, SMC, CADTH or PBAC. ◾Authors, editors or reviewers who wish to assess the novelty of a new mapping study. ◾Those conducting systematic reviews of methods for estimating utilities or QALYs. ◾Those seeking to identify the estimation models and sample sizes currently used in mapping studies and identify new developments for further research. Systematic review of studies mapping to EQ-5D from other quality of life or clinical measures

Description:: Background: The Health Economics Research Centre (HERC) Database of Mapping Studies was established in 2013, based on a systematic review of studies developing mapping algorithms predicting EQ-5D. The Mapping onto Preference-based measures reporting Standards (MAPS) statement was published in 2015 to improve reporting of mapping studies. We aimed to update the systematic review and assess the extent to which recently-published studies mapping condition-specific quality of life or clinical measures to the EQ-5D follow the guidelines published in the MAPS Reporting Statement. Methods: A published systematic review was updated using the original inclusion criteria to include studies published by December 2016. We included studies reporting novel algorithms mapping from any clinical measure or patient-reported quality of life measure to either the EQ-5D-3L or EQ-5D-5L. Titles and abstracts of all identified studies and the full text of papers published in 2016 were assessed against the MAPS checklist. Results: The systematic review identified 144 mapping studies reporting 185 algorithms mapping from 110 different source instruments to EQ-5D. Of the 17 studies published in 2016, nine (53%) had titles that followed the MAPS statement guidance, although only two (12%) had abstracts that fully addressed all MAPS items. When the full text of these papers was assessed against the complete MAPS checklist, only two studies (12%) were found to fulfil or partly fulfil all criteria. Of the 141 papers (across all years) that included abstracts, the items on the MAPS statement checklist that were fulfilled by the largest number of studies comprised having a structured abstract (95%) and describing target instruments (91%) and source instruments (88%). Conclusions: The number of published mapping studies continues to increase. Our updated database provides a convenient way to identify mapping studies for use in cost-utility analysis. Most recent studies do not fully address all items on the MAPS checklist.
Related item:: Review of studies mapping from quality of life or clinical measures to EQ-5D: an online database
Description:: 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 estimated EQ-5D utilities from 80 source instruments. All but two studies included direct utility mapping to predict EQ-5D utilities, while 20 studies (22%) conducted response mapping to predict responses to each EQ-5D domain. Seventy-two studies (80%) explored ordinary least squares regression and 16 (18%) used censored least absolute deviations (CLAD) models. The details of the studies identified are made available in an online database, which will be updated regularly to enable researchers to easily identify studies that can help them to estimate utilities for economic evaluation.
