Appraisal of: Bak G, Mierzwinski-Urban M, Fitzsimmons H, Morrison A, Maden-Jenkins M. A pragmatic critical appraisal instrument for search filters: introducing the CADTH CAI. Health Info Libr J. 2009 Sep;26(3):211-9
This paper describes the search for a pragmatic critical appraisal instrument (CAI) that experienced systematic review searchers can use in the selection of robust search filters. A focused search of the literature identified a single candidate - the critical appraisal tool developed by Michelle Jenkins. Testing of this showed that its use requires an in-depth understanding of search filter methodology and statistics that not all information specialists may possess. In light of these findings, the authors substantially revised the tool to consist of 6 domains and 10 closed questions. Instructions about how to use the tool are provided. It features a key question about whether the filter being appraised is up to date.
