Advanced practice nurses and evidence-based practice. An opportunity for change.

In a context of aging of the population, increased prevalence of chronic diseases and increasing complexity, it is necessary to define new professional roles that can meet the health needs of the population. Added to this is the certainty that variability in clinical practice, as well as in health management, makes it necessary to use best evidence as the basis for decision-making. But the application of clinical practice based on evidence in a specific context implies a broad mastery of the available evidence, its applicability and limitations, as well as a deep understanding of the particular characteristics of the area where it is to be applied, from the "macro" (health policies, framework regulations, strategic lines, social values, etc.) to the "micro" level (local culture, user preferences, etc.). The "Health Service of the Balearic Islands", in collaboration with the Faculty of Nursing and Physiotherapy from the University of the Balearic Islands, proposes the development of new advanced practice nursing roles that focus their efforts on the planned implementation of evidence in clinical settings. Advanced practice nurses have managed naturally, thanks to their competence development, to exercise the role of promoting organizational and attitudinal changes that facilitate the implementation of evidence in organizations and complex environments.
