    Altmetric:

     

    Bottom Line:

    • Introduces a series of articles describing the results of a scoping review on emerging knowledge synthesis methods

    Impact:

    • The results of this scoping review can be used to inform a research agenda to advance these methods in the knowledge synthesis field

    Paper 2: A scoping review identifies multiple emerging knowledge synthesis methods, but few studies operationalize the methods

    Tricco AC, Soobiah C, Antony J, Cogo E, MacDonald H, Lillie E, Tran J, D'Souza J, Hui W, Perrier L, Welch V, Horsley T, Straus SE, Kastner M. A scoping review identifies multiple emerging knowledge synthesis methods, but few studies operationalize the method. J Clin Epidemiol. 2016;73:19-28. DOI: 10.1016/j.jclinepi.2015.08.030

     

    Altmetric:

     

    Bottom Line:

    • Twelve knowledge synthesis methods were classified as methods that can be used for the entire synthesis process; while 13 were classified as methods that provide guidance on the analysis alone
    • Identified a lack of guidance in emerging knowledge synthesis methods integrating qualitative and quantitative evidence

    Impact:

    • The results of this scoping review can be used to inform a research agenda to advance these methods in the knowledge synthesis field

    Paper 3: Knowledge synthesis methods for integrating qualitative and quantitative data: a scoping review reveals poor operationalization of the methodological steps

    Tricco AC, Antony J, Soobiah C, Kastner M, MacDonald H, Cogo E, Lillie E, Tran J, Straus SE. Knowledge synthesis methods for integrating qualitative and quantitative data: a scoping review reveals poor operationalization of the methodological steps. J Clin Epidemiol. 2016;73:29-35. DOI: 10.1016/j.jclinepi.2015.12.011

     

    Altmetric:

     

    Bottom Line:

    • Seven knowledge synthesis methods were identified in the literature that can be used to integrate qualitative and quantitative data (e.g., integrative review, mixed studies review, realist review, meta-summary, meta-narrative review, narrative synthesis, and critical interpretive synthesis)
    • Some of the knowledge synthesis methods provided guidance on all steps, whereas other methods were missing guidance on the synthesis process

    Impact:

    • The results of this scoping review can be used to inform a research agenda to advance these methods in the knowledge synthesis field

    Paper 4: Knowledge synthesis methods for generating or refining theory: a scoping review reveals that little guidance is available

    Tricco AC, Antony J, Soobiah C, Kastner M, Cogo E, MacDonald H, D'Souza J, Hui W, Straus SE. Knowledge synthesis methods for generating or refining theory: a scoping review reveals that little guidance is available. J Clin Epidemiol. 2016;73:36-42. DOI: 10.1016/j.jclinepi.2015.11.021

     

    Altmetric:

     

    Bottom Line:

    • Nine knowledge synthesis methods (e.g., concept synthesis, critical interpretive synthesis, integrative review, meta-ethnography, meta-interpretation, meta-study, meta-synthesis, narrative synthesis, and realist review) were identified in the literature for the purpose of generating and refining theory
    • Guidance for conducting these emerging knowledge synthesis methods are often vague and sometimes absent

    Impact:

    • The results of this scoping review can be used to inform a research agenda to advance these methods in the knowledge synthesis field

    Paper 5: Conceptual recommendations for selecting the most appropriate knowledge synthesis method to answer research questions related to complex evidence: A scoping review

    Kastner M, Antony J, Soobiah C, Straus SE, Tricco AC. Conceptual recommendations for selecting the most appropriate knowledge synthesis method to answer research questions related to complex evidence. J Clin Epidemiol. 2016;73:43-9. DOI: 10.1016/j.jclinepi.2015.11.022

     

    Altmetric:

     

    Bottom Line:

    • Provided conceptual recommendations for selecting the most appropriate knowledge synthesis method to answer complex research questions

    Impact:

    • The results of this scoping review can be used to inform a research agenda to advance these methods in the knowledge synthesis field

    Knowledge synthesis research: a bibliometric analysis

    Perrier L, Lightfoot D, Kealey MR, Straus SE, Tricco AC. Knowledge synthesis research: a bibliometric analysis. J Clin Epidemiol. 2016;73:50-7. DOI: 10.1016/j.jclinepi.2015.02.019

     

    Altmetric:

     

    Bottom Line:

    • There is an absence of subject headings used for indexing, that help researchers and research users identify articles that describe and explain specific synthesis methods

    Impact:

    • This study aims to encourage effective indexing: identifying subject headings to discern distinct methods, which can provide clarity and assist researchers or research users in locating literature offering guidance on the methodologies of conducting evidence synthesis
