[How often do medical guidelines refer to articles written in Dutch?].

Objective: For Dutch medical guidelines, Dutch research articles published in the NTvG (NederlandsTijdschriftvoorGeneeskunde) and other medical journals are not searched systematically and are only used sporadically. Using these publications in the process of guideline development can be useful for recommendations regarding the Dutch context of care. In this research, we have investigated how often and in which parts of Dutch guidelines articles published in NTvG are used.

Design: We specifically investigated how often articles published in NTvG are mentioned in Dutch medical guidelines published on www.richtlijnendatabase.nl, that were developed in 2019, 2020 and 2021.

Method: In all parts of new or revised Dutch medical guidelines published in these years on www.richtlijnendatabase.nl, we searched for references of articles published in NTvG.

Results: The results show that in 3% of all Dutch medical guidelines a reference to an article published in NTvG is made. These references were made in the literature summaries (21% of the references), the reflections on the literature for the Dutch context of care (48% of the references), or in other areas such as the introduction (10% of the references) or appendices (21% of the references).

Conclusion: Articles published in NTvG may be relevant for making recommendations in Dutch medical guidelines, as these publications usually reflect the Dutch care context, and may do more so than research published in international journals. The results of this research show that the number of Dutch guidelines where these articles are used is limited. Dutch research articles may be a source of information that is yet to be tapped into.
