Reproducibility of Search Strategies in Systematic Reviews Preliminary Results Jonathan Koffel, MSI Bio-Medical Library, University of Minnesota Melissa Rethlefsen, MLIS AHIP Eccles Health Sciences Library, University of Utah
Rise of the Systematic Review Reporting Guidelines: PRISMA MOOSE Cochrane Institute of Medicine
Describe all information sources (e.g., databases with dates of coverage, contact with study authors to identify additional studies) in the search and date last searched. Present full electronic search strategy for at least one database, including any limits used, such that it could be repeated. Preferred Reporting Items for Systematic Reviews and Meta-Analyses, 2009
“The Scopus, EBSCOhost, Ovid, and Web of Science platforms were searched.” Pediatrics. 2012 Mar;129(3):548-56
Previous Research Good reporting of some search elements 2 –Database names, search terms Poor reporting of other elements 2 –Date search executed, database platform Reproducibility is heterogeneously defined, but generally low 3,4 2 Sampson et al. J Clin Epidemiol. 2008 Aug;61(8):748-54. 3 Yoshii et al. J Med Libr Assoc. 2009 Jan;97(1):21-9. 4 Golder et al. J Clin Epidemiol. 2013 Mar;66(3):253-60
Purpose 1.Examine search reporting and reproducibility in systematic reviews published in high-impact medicine journals in 2012 2.Investigate the impact of librarian involvement and reporting guidelines on reporting/reproducibility rates
Hypotheses 1.Reporting/reproducibility rates will be higher when a librarian was involved. 2.Reporting/reproducibility rates will be higher when a guideline was mentioned or required by the journal.

Identification of Studies PubMed search on 9/2/2013 using modified Montori strategy 5 (search*[Title/Abstract] OR meta-analysis[Publication Type] OR MEDLINE[Title/Abstract] OR EMBASE[Title/Abstract] OR Meta- analysis[Title/Abstract] OR (systematic[Title/Abstract] AND review[Title/Abstract]) AND (("2012/01/01"[PDat] : "2012/12/31"[PDat]) PubMed SR subset filter also used for comparison –<4% of included articles found only by Montori strategy 5 Montori et al. BMJ. 2005 Jan 8;330(7482):68.
Identification of Studies All retrieved studies screened by both authors to identify systematic reviews –Searches at least one published literature database –Inclusion/exclusion criteria are prespecified –Does not limit to a certain number of journals or subset of journals Disagreements resolved by review of original articles and consensus
