This study reviews national literature about the Systematization of Nursing Assistance in order to detect and reflect on the phases of its implementation. An electronic search of the data bases at LILACS, MEDLINE and BDENF revealed 61 published studies on this subject in nursing journals. This present study focuses on negative experiences regarding its implementation and presents a strategy for its successful implementation. The plan was observed to have various phases, but it was observed that the institution's structure, facilities and demands had to be first studied. It was concluded that the process for its implementation would be complex and difficult, but could contribute towards improving the quality of nursing care.59675-9
