The First Meeting of the Spanish European Project on Nursing was held in León from May 24th to 26th 1990. This seminar was attended by nursing professionals from 11 Spanish hospitals participating in the Project. During the meeting, an important discussion was held on the protocols used with regard to practical aspects, in order to unify criteria and homologate the results obtained by the different centres. By means of this seminar, Spanish professionals made an important contribution to the design of this Spanish project, not only as collaborators but also as active participants in the research conducted.
