Literature research & systematic reviews

The (medical) information specialists advise on and execute the literature research for, amongst others, systematic reviews, guidelines, funding applications, PhD research, PICOs and CATs.

Why is good literature research important?

Systematic reviews establish the ‘state-of-the-art knowledge’ of a subject to serve as a solid base for care/cure and evidence-based medicine (EBM). The scientific method to establish this knowledge is a thorough and systematic literature research, without bias, in multiple sources and as complete as possible. This method must be sensitive and must be clearly presented to be reproducible. A medical information specialist is the expert in efficiently performing this research and is indispensable in this process. See for more information on systematic searches the guidelines in the Cochrane Handbook and the Standards for systematics reviews (IoM). Evidence about the beneficial role of the information specialist in literature research can be found in research by Koffel (2015) and Rethlefsen et al. (2015).

We request co-authorship for the involved information specialist, because he/she is responsible for the research method: translation of the research question in a search strategy and the construction thereoff, documenting this in a logbook and representation of this process in the publication. The information specialist bears the responsibility to execute the research method meticulously, complete and reproducible. In executing the method the information specialist becomes co-responsible for the manuscript for the editorial board, peer reviewers and readers. To state this responsibility clearly a co-authorship is applicable.
