[An evidence-based healthcare system and the role of the healthcare professions].

An evidence-based healthcare system necessitates a new role allocation and new role definitions of the players. By means of professional delegation, physician-nurse substitution and adoption of new professional functions, which so far have not been part of their professional profiles, nurses, midwives and allied health professionals will adopt a broad spectrum of new responsibilities. At present, nurses, midwives and allied health professionals lack basic scientific competencies and opportunities to acquire skills in evidence-based practice. A reliable link between evidence-generating sciences in nursing, midwifery and allied health professions and clinical practice is missing. In the future, an increase of academically qualified health professionals and a new skills mix within each profession might promote active and effective participation in an evidence-based healthcare system.
