Abstract

Background Moral distress is a major issue in intensive care units that requires immediate attention since it can cause nurses to burnout. Given the special conditions of patients in intensive care units and the importance of the mental health of nurses, the present study was designed to systematically review the factors affecting moral distress in nurses working in intensive care units. Methods PubMed, EMBASE, Web of Science, Scopus, and Science Direct were systematically searched for papers published between 2009 and 2019. Original articles from quantitative and qualitative studies were reviewed. The CONSORT and STROBE checklists were used to assess the quality of the quantitative papers. The JBI checklist was applied for qualitative studies. Results Factors affecting moral distress in nurses include lack of nursing staff, nurses with inadequate experience, lack of support from organizations and colleagues, inadequate education and lack of knowledge of nurses, poor collaboration of physicians with nurses, ethical insensitivity and lack of teamwork, heavy workload, poor quality of care and moral violence and they are considered as risk factors for moral distress. Conclusion Many of the related causes are due to the nature of nurses’ work and it is necessary to manage the underlying conditions of this phenomenon so that it can be effectively prevented from spreading. Levels of moral distress require more attention of authorities in the use of prevention strategies and the reduction of effective factors in distress.
