A qualitative study will be performed with the aim to discover factors in detail that are "pro" or "contra" adhering to the developed HPP-indicators by focus group interviews among groups of different involved professionals and experienced patients. Subsequently, to assess the 'prevalence' of the factors mentioned in the focus group interviews, a survey with questionnaires will be performed among all Dutch gynaecologists and midwives. The data will be analyzed to assess the most frequently mentioned barriers and facilitators.
