BackgroundUnderstanding factors that can potentially influence patient care and nursing workload in intensive care units is important. Previous studies have shown contradictory outcomes about the relationships between nursing workload and patient and nurse characteristics.Aims And ObjectivesThis study aimed to investigate nursing workload in intensive care units and examine the association between this in relation to patient and nurse characteristics.DesignA cross-sectional design was conducted.MethodsAll nurses who were working in the intensive care units of five hospitals and met the study criteria were enrolled in the study. Two demographic questionnaires collected nurse and patient demographic information. The Nursing Activities Score was applied to determine nursing workload in three shifts (morning, evening, night) for each nurse. Data were analysed using the independent sample t-test, one-way analysis of variance, and multivariable linear regression analysis.ResultsThe Nursing Activities Score was calculated for 509 patients who were under the care of 105 intensive care unit nurses. The mean (SD) Nursing Activities Score was 72.84% (22.07%). Morning shifts, male patients, medical treatments, and referred patients from the emergency ward and other intensive care units imposed a higher workload for nurses. Specifically, female nurses, increased number of patients receiving care, and increased patient length of intensive care unit stay were directly associated with increased Nursing Activities Scores. Work in surgical and burn intensive care units were inversely associated with the Nursing Activities Score.ConclusionThis study suggests that the workload of nurses in intensive care units can be affected by both nurse and patient characteristics.Relevance To Clinical PracticeThe findings can be used to ensure appropriate staffing of intensive care units by nurses. However, nurse and patient characteristics should not be considered the only factors that influence nursing workload in intensive care units.© 2020 British Association of Critical Care Nurses.
