SERAFIM, Clarita Terra Rodrigues et al. Severity and workload related to adverse events in the ICU. Rev. Bras. Enferm. [online]. 2017, vol.70, n.5, pp.942-948. ISSN 0034-7167.


To analyze whether an increase in patient severity and nursing workload are correlated to a greater incidence of adverse events (AEs) in critical patients.


A prospective single cohort study was performed on a sample of 138 patients hospitalized in an intensive care unit (ICU).


A total of 166 AEs, occurred, affecting 50.7% of the patients. Increased patient severity presented a direct relationship to the probability of AEs occurring. However, nursing workload did not present a statistically significant relationship with the occurrence of AEs.


The results cast light on the importance of using evaluation tools by the nursing personnel in order to optimize their daily activities and focus on patient safety.
