BackgroundFew examples exist of research capacity building (RCB) in midwifery. As in other jurisdictions, at the turn of this century midwives in the Netherlands lagged in research-based practice. Dutch professional and academic organisations recognised the need to proactively undertake RCB. This paper describes how a large national research project, the DELIVER study, contributed to RCB in Dutch midwifery.MethodsApplying Cooke’s framework for RCB, we analysed the impact of the DELIVER study on RCB in midwifery with a document analysis comprising the following documents: annual reports on research output, websites of national organizations that might have implemented research findings, National Institute for Public Health and the Environment (RIVM)), midwifery guidelines concerning DELIVER research topics, publicly available career information of the PhD students and a google search using the main research topic and name of the researcher to look for articles in public papers.ResultsThe study provided an extensive database with nationally representative data on the quality and provision of midwifery-led care in the Netherlands. The DELIVER study resulted in 10 completed PhD projects and over 60 publications. Through close collaboration the study had direct impact on education of the next generation of primary, midwifery care practices and governmental and professional bodies.DiscussionThe DELIVER study was intended to boost the research profile of primary care midwifery. This reflection on the research capacity building components of the study shows that the study also impacted on education, policy, and the midwifery profession. As such the study shows that this investment in RCB has had a profound positive impact on primary care midwifery in the Netherlands.
