Introduction:

The use of the Nursing Activity Score (NAS) makes it possible to correlate the nursing workload with prognostic evaluation indices in the intensive care unit and helps in the development of the nurses' work process through the sizing of the appropriate personnel.

Objective:

To analyze the association between clinical and demographic variables about patients with a nursing workload in an oncology intensive care unit.

Methods:

Prospective cohort study carried out at José Alencar Gomes da Silva National Cancer Institute, from September to December 2016. The data collection includes the measurement of the workload through the Nursing Activities Score. A descriptive statistical analysis of the data was performed. Afterwards, the association between qualitative variables and the NAS was tested using the Kruskal-Wallis test and the quantitative variables were analyzed using multiple regression analysis. For data treatment, significance was considered (P = 0.05; confidence interval 95%).

Result:

The total workload found (79.04%) corresponds to 18 hours and 57 minutes of assistance to each patient within 24 hours. The mean for the discharge condition of the patients is divided into survivors and non-survivors, with a score of 74.19% (SD=11.54) and 126.64% (SD=17.62), respectively.

Conclusion:

Only Karnofsky performance state variables and discharge condition were significantly associated with workload.
