Moral Distress Scores of Nurses Working in Intensive Care Units for Adults Using Corley’s Scale: A Systematic Review

Abstract

Background: No systematic review in the literature has analyzed the intensity and frequency of moral distress among ICU nurses. No study seems to have mapped the leading personal and professional characteristics associated with high levels of moral distress. This systematic review aimed to describe the intensity and frequency of moral distress experienced by nurses in ICUs, as assessed by Corley’s instruments on moral distress (the Moral Distress Scale and the Moral Distress Scale–Revised). Additionally, this systematic review aimed to summarize the correlates of moral distress. Methods: A systematic search and review were performed using the following databases: Cumulative Index to Nursing and Allied Health Literature (CINAHL), the National Library of Medicine (MEDLINE/PubMed), and Psychological Abstracts Information Services (PsycINFO). The review methodology followed PRISMA guidelines. The quality assessment of the included studies was conducted using the Newcastle–Ottawa Scale. Results: Findings showed a moderate level of moral distress among nurses working in ICUs. The findings of this systematic review confirm that there are a lot of triggers of moral distress related to patient-level factors, unit/team-level factors, or system-level causes. Beyond the triggers of moral distress, this systematic review showed some correlates of moral distress: those nurses working in ICUs with less work experience and those who are younger, female, and intend to leave their jobs have higher levels of moral distress. This systematic review’s findings show a positive correlation between professional autonomy, empowerment, and moral distress scores. Additionally, nurses who feel supported by head nurses report lower moral distress scores. Conclusions: This review could help better identify which professionals are at a higher risk of experiencing moral distress, allowing the early detection of those at risk of moral distress, and giving the organization some tools to implement preventive strategies.

The influence of psychological resilience and nursing practice environment on nurses' moral courage: A cross‐sectional study

“…In addition, moral courage also affects the personal development of nurses. The literature indicates that the lack of moral courage will reduce the professional identity of nurses, resulting in job burnout, moral apathy, mental distress, and even turnover, which ultimately leads to a shortage of human resources (Berdida, 2023;Giannetta et al, 2022;Kleemola et al, 2020). The potential and widespread future impact of moral courage on nurses, patients, and the health care system reinforces the need to focus on the level of moral courage.…”

How Do Nursing Students Perceive Moral Distress? An Interpretative Phenomenological Study

“…when they feel that the ethically correct action to take is different from what they are tasked with doing [ 1 ]. Several studies are focused on moral distress among the nursing population [ 2 , 3 , 4 , 5 ]. Research shows that the longer nurses care for terminally ill patients, the greater they experience M.D.…”

Translation and validation of the “Moral Injury Symptom Scale-Healthcare Professionals” in Greek

“…Moral injury can occur when nurses have to deal with di cult ethical issues (Morley, Bradbury-Jones & Ives, 2022). Moral injury is de ned as the psychological distress that arises in situations where healthcare professionals know what is morally right to do, but due to circumstances are unable to do it (Giannetta et al, 2022). Moreover, moral injury can lead to low productivity and mental health issues, particularly if it persists over a long period of time (Čartolovni et al, 2021) Healthcare professionals in particular during the COVID-19 pandemic experienced unprecedented working conditions with professional demands increasing sharply in an already exhausting working environment.…”
