Background: The research on nursing professionals in Clinical Ethics Committees and Nursing Ethics Commissions occurs in different parts of the world; however, little information on this subject is found in the literature. Objective: This study analyzed national and international publications in relation to the participation of nursing professionals in Clinical Ethics Committees. Research design: This was an integrative review of articles published in national and international journals between 1994 and 2016 which described the participation of nursing professionals in ethics commissions. (...) Participants and research context: A total of 35 articles were selected. Discussion and conclusion for this article: The thematic categories were the need for time to discuss ethical issues; ethics committee to reduce the moral suffering of professionals; competencies required for participation; and barriers/difficulties and facilitators for implementation/ performance. It was concluded that professionals recognize the need for ethics committees to foster discussions. However, barriers hamper operation and fundamental competencies for participation. Communication of committee activities to professionals and educational activities may be major allies to improve the functioning of these committees. (shrink)
