Özet:

Aim: Although the use of international standard classification systems in nursing care is effective in improving patient outcomes, studies are limited. The aim of this systematic review is to examine the postgraduate nursing theses in Turkey in which the effectiveness of the NANDA-I, NOC and NIC classification systems are evaluated. Materials and methods: The data of this review were obtained retrospectively. Data searching was carried out for the theses published in the National Thesis Screening Center of the Council of Higher Education between the years 2012-2022. The keywords "NANDA", "NOC", "NIC", "nursing process", "nursing diagnosis", "classification", "nursing outcome", "nursing intervention" and "nursing" were used in the search. The theses that are accessible to the research, whose full text is accessible, which use NANDA-I, NOC and NIC systems together in their methods, which are in experimental research design and which are made in the field of nursing are included. As a result of the search, 133 theses were reached. Eight theses that met the inclusion criteria were included in the research and their full texts were examined in detail. Results: Six of the theses examined are doctoral and two are master's theses. All theses were done in 2015 and after. The sample group of the theses consisted of patients (n=5), patient relatives (n=1) and nursing students (n=2). In studies conducted with patients or their relatives, the positive effects of using the three systems on care have been shown. In studies conducted with nursing students, it has been determined that the use of three systems together in nursing education is effective in teaching the nursing process. Conclusion: The results of the study show that the use of the three systems together has positive effects on patient care and nursing education. There is a need for studies examining the effects of nursing processes in which NANDA-I, NOC and NIC systems are used together.
