Factors contributing to moral distress among intensive care nurses: A scoping review

Abstract

Background: The intensive care unit (ICU) is a busy and complex workplace, and several work-related and personal factors are known to make ICU nurses more vulnerable to moral distress than other healthcare professionals. It is crucial to identify these factors to guide future studies and preventive strategies. This scoping review explores such factors to present current knowledge on the factors that trigger moral distress and to guide future research by reviewing studies to explore and summarize factors that trigger moral distress in ICU nurses.   Methods: The PubMed, EBSCO, and CINAHL Plus databases were searched to identify potentially relevant studies published between 2011 to 2022. Inclusion criteria: peer-reviewed studies published in English that provided results regarding factors causes or correlated to moral distress in ICU nurses. After removing 63 duplicates, 371 papers were excluded after title and abstract screening, leaving 47 articles for full-text screening. A further 30 articles were excluded as their outcomes did not include factors that caused moral distress, or were not specific to ICU nurses, so 17 studies were eventually analysed using qualitative content analysis through an inductive approach. The findings of the articles were extracted and coded independently by two authors, and data were grouped and categorized. Results: The content categories of factors contributing to ICU nurses' moral distress were organized into themes and subthemes. Four major themes were identified: Powerlessness, end-of-life care, ineffective teamwork, and personal characteristics of ICU nurses.   Conclusions: This review highlights the factors that contribute to moral distress in critical care nurses, which are mainly attributable to the organizational climate and the nature of the ICU clinical environment. Descriptive and intervention studies (experimental or action research) must investigate causality between identified variables to inform management strategies to improve support for ICU nurses’ coping relative to moral distress.
