Ethics and research in nursing

Considering the importance of research in the development of nursing, we examine the ethical principles governing nurses' investigative activity, as well as the different codes regulating biomedical investigation with human beings, amongst which are the Nuremberg Code, the Declaration of Human Rights, and the Declaration of Helsinki. From the perspective of the central points of the article reference is made to different codes proposed by international nursing associations, as well as reviewing the Deontological Code of Spanish Nursing. The ethical principles a nurse has to bear in mind in research are analysed, with respect to patients, society and the profession. Finally, we refer to certain ethical aspects to be considered in the elaboration and development of a research project, as well as publication of the results.
