Background and aim: Surgical intensive care nurses should have ethical sensitivity allowing them to identify ethical issues in order that they can recognize them and make the right decisions. This descriptive study was conducted with the aim of evaluating the ethical sensitivity of surgical intensive care nurses. Materials and methods: The research was carried out with the participation of 160 nurses in six Turkish hospitals, four state, one university, and one private. The data were collected using the "Nurse Description Form" developed by the researcher and the "Ethical Sensitivity Questionnaire." The percent, mean, standard deviation, median, minimum and maximum values, significance test for the difference between two means, variance analysis, Mann-Whitney U test, and Kruskal-Wallis Variance Analysis test were used to evaluate the data. Ethical considerations: Ethical commission permission and the corporate permission of the hospitals were received before conducting the research. Results: It was determined that the ethical sensitivities of surgical intensive care nurses were moderate based on the Ethical Sensitivity Questionnaire total score and subdimension score averages. A statistical difference was determined between the Ethical Sensitivity Questionnaire total score of surgical intensive care nurses and the institution where they worked, the period of working in the occupation, and the period of working in the intensive care unit (p < 0.05). Conclusion: Based on the results of the research, the organization of training and studies devoted to the elimination of ethical sensitivity differences between institutions and workers is suggested.
