Quality of life of critical care nurses and impact on anxiety, depression, stress, burnout and sleep quality: A cross-sectional study

Objectives: To investigate how anxiety, depression, stress, burnout, and sleep quality impact on Quality of life of critical care nurses. Background: Several studies reported that critical care nurses are exposed to a high risk of anxiety, depression, burnout, stress, and sleep quality, but we do not know the impact of critical care nurses. Design: A cross-sectional study. Methods: We have included all critical care nurses working in the intensive care unit for at least six months. Data were collected from December 1, 2021, to March 18, 2022. We evaluated the critical care nurses using the Depression Anxiety Stress Scale (DASS), Maslach Burnout Inventory scale, Pittsburgh Sleep Quality Index and Nurse Quality of Life. The primary endpoint is Quality of Life. Associations were tested using multivariate modelling. Results: A total of 140 critical care nurses were included. Multivariate regression showed the relation between emotional QoL and emotional exhaustion and DASS total score [OR = 0.14; 95% CI (0.03–0.73); p = 0.019 and OR = 3.64; 95% CI (1.07–12.32); p = 0.038, respectively]. Personal accomplishment and DASS total score have a direct relationship on quality of work-life [OR = 0.21; 95% CI (0.05–0.82); p = 0.024 and OR = 4.18; 95% CI (1.01–17.33); p = 0.049, respectively]. Conclusions: The physical quality of life is not optimal in critical care nurses, while burnout and the DASS score directly impact the emotional and work-life quality of life. Implications for clinical practice: Our research has highlighted the importance of detecting the quality of life of critical care nurses. The nurses should take proper care of their health by adopting the right health behaviours to create correct work conditions and increase the quality of care for critically ill patients.
