Short description: 
This article reports the findings of a qualitative survey on the usefulness of NHS EED to lead authors of NICE Technology Assessment Reviews (TARs). The survey was conducted by mail and included questions on usefulness in identifying economic studies, extracting data, completing quality assessments, and informing decisions to commission modeling studies. NHS EED was used in 90% of all identified TARs and found to be generally useful, especially for retrieving economic evidence (62% of respondents), followed by literature quality assessment. However, a high proportion didn’t find NHS EED relevant to quality assessment and data extraction as the TAR protocol is to use the primary study. The time lag between introduction of a technology, the publication of an economic evaluation, and the article abstraction for NHS EED is also discussed.
Limitations stated by the author(s): 
Low survey response rate (63%). Respondents may have been motivated to complete the survey by a lack of economic evaluations in their topic areas.
Limitations stated by the reviewer(s): 
No additional limitations detected by the reviewer.
Study Type:
