Abstract

Nursing is considered to be an at-risk profession of burnout due to daily exposure to difficult situations such as death and pain care. In addition, some units such as the intensive care unit (ICU), can be stressful due to high levels of morbidity and mortality and ethical dilemmas. Burnout causes a deterioration in quality of care, increasing the risk of mortality in patients due to poor performance and errors in the healthcare environment. The aim of this study was to analyse the levels, prevalence and related factors of burnout in ICU nurses. A systematic review and meta-analysis were carried out in the Medline, Scopus and CINAHL databases. Fifteen articles were found for the systematic review and four for the meta-analysis. With a sample of n = 1986 nurses, the meta-analytic estimate prevalence for high emotional exhaustion was 31% (95% CI, 8–59%), for high depersonalization was 18% (95% CI, 8–30%), and for low personal accomplishment was 46% (95% CI, 20–74%). Within the dimensions of burnout, emotional exhaustion had a significant relationship with depression and personality factors. Both sociodemographic factors (being younger, single marital status, and having less professional experience in ICU) and working conditions (workload and working longer hours) influence the risk of burnout syndrome.

  • Approximately half of physicians and nurses in the US report significant burnout symptoms in the form of high emotional exhaustion, high depersonalization, and/or a low sense of personal accomplishment.

    “According to most recent studies, approximately half of physicians and nurses in the US report significant burnout symptoms in the form of high emotional exhaustion, high depersonalization, and/or a low sense of personal accomplishment.3-5”

    From What do we really know about addressing burnout among healthcare workers? Maybe less than we think (2026) · cites this paper as [4]

    The Introduction (page not provided) identifies high emotional exhaustion, high depersonalization, and low personal accomplishment as indicators of burnout. The paper’s meta-analytic estimates, however, concern ICU nurses and are 31%, 18%, and 46% for those dimensions, respectively. It does not establish that approximately half of US physicians and nurses report burnout symptoms. (LLM, conf=0.88)

  • Emotional exhaustion is closely related to levels of depressive symptomatology, especially in the early stages of the pandemic.

    “According to the existing literature, emotional exhaustion is closely related to levels of depressive symptomatology, especially in the early stages of the pandemic (49, 52).”

    From Evolution of burnout syndrome in Spanish healthcare professionals during and after the COVID-19 pandemic: psychosocial variables involved (2025) · cites this paper as [52]

    The Results (§3.3) say emotional exhaustion was significantly related to depression among ICU nurses, and the Conclusions (§5) repeat that finding. The paper does not establish that this relationship was especially pronounced in the early stages of the pandemic. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Previous studies relate cognitive fusion and depression to emotional exhaustion, and low levels of resilience with burnout.

    “This is consistent with previous studies that relate cognitive fusion (54) and depression (49, 52) to emotional exhaustion, and low levels of resilience with burnout (55, 56).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
