Fatigue and sleep in intensive care nursing workers in the COVID-19 pandemic

Abstract

Objective: To analyze the relationship between fatigue, sleep quality, variables of health and work in intensive care nursing workers during the COVID-19 pandemic. Methods: Cross-sectional, correlational study conducted from July 2020 to February 2021 with a random and probabilistic sample of nurses and nursing technicians from university hospitals in Rio Grande do Sul, Brazil. A sociodemographic/occupational questionnaire, the Fatigue Assessment Scale and the Pittsburgh Sleep Quality Index were used in data collection. The chi-square test, Mann-Whitney U test and the Spearman correlation coefficient were used in the analyzes, adopting a significance level of 5%. Binary logistic regression analysis was performed. Results: Participation of 114 workers. There was prevalence of low fatigue and poor sleep quality. High fatigue was associated with the variables going to work sick and perceiving noise/vibrations as a cause of discomfort. Nursing technicians were associated with poor sleep quality and concern about exposure to chemical substances. Fatigue and sleep quality were moderately and directly correlated. Adjusted analyzes showed that nurses and nursing technicians with high fatigue were four times more likely to have poor sleep quality (OR = 4.86; CI = 1.50-15.75). Conclusion: Fatigue and sleep quality were directly correlated and are associated with individual and work factors. High fatigue increased the chances of having worse sleep quality assessment. Institutional and organizational strategies should be reviewed in order to prioritize the health protection of these nursing workers.
