Notes:
Drafted to search specifically for guidelines. This search block was developed by a group of medical information specialists. This project is funded by the Biomedical Information Specialists (BMI)-group. The project as a whole aims to develop a guideline (‘Leidraad’) for searching for guidelines in cooperation between the Knowledge Institute of the Federation of Medical Specialists (https://www.demedischspecialist.nl/kennisinstituut) and the BMI. The BMI is a working group of the KNVI (Royal Dutch Society for Information Professionals).
