Development of burnout and moral distress in intensive care nurses: An integrative literature review

To describe, through an integrative literature review, the factors contributing to the development of burnout and moral distress in nursing professionals working in intensive care units and to identify the assessment tools used most frequently to assess burnout and moral distress.

An integrative literature review was carried out. PubMed, CINAHL, PsycINFO, SciELO, Dialnet, Web of Science, Scopus, and Cochrane databases were reviewed from January 2012 to February 2023. Additionally, snowball sampling was used. The results were analysed by using integrative synthesis, as proposed by Whittemore et al., the Critical Appraisal Skills Programme for literature reviews, the Strengthening the Reporting of Observational Studies in Epidemiology guidelines for quantitative observational studies, and the Joanna Briggs Institute checklist for qualitative research were used to evaluate evidence quality.

Forty-one articles were selected for review: 36 were cross-sectional descriptive articles, and five were literature reviews. The articles were grouped into five-factor categories: 1) personal factors, 2) organisational factors, 3) labour relations factors, 4) end-of-life care factors, and 5) factors related to coronavirus disease 2019 (COVID-19). The Maslach Burnout Inventory-Human Services Survey and the Moral Distress Survey-Revised instruments were the most commonly used to measure burnout and moral distress.

This review highlights the multiple personal, organisational, relational, situational, and end-of-life factors promoting burnout and moral distress among critical care nurses. Interventions in these areas are necessary to achieve nurses' job satisfaction and retention while improving nurses' quality of care.
