RESUMO

This is a quantitative, cross sectional, descriptive study performed with the aim of identifying the nursing workload according to the Nursing Activities Score (NAS) at a large scale adult Intensive Care unit of a public teaching hospital, aimed at attending patients in Immediate or Urgent medical situations. The sample was composed of 70 patients aged over 18 years of age, independent of the diagnosis of type of treatment, who stayed in the unit for a minimum of 24 hours. The data collection, carried out between May and October 2011, was composed of demopgraphic and clinical data and the NAS values and the APACHE II severity index durring the first 24 hours were applied after admission to measure the nursing workload and the severity of the patients respectively. Inferential and descriptive statistics were used to process the data, with the relation between selected variables analysed using the Pearson correlation coefficient. The student T test and ANOVA were used for the comparison of means. The combined analysis of the variables was done using multiple linear regression. The majority of the patients 26 (62.86%) were male with a mean age of 46.31, the mean time they were admitted to ICU was 12.76 (sd=10.30). The majority of patients were transferred from the Emergency Room (45.71%), with clinical admission (54.29%) and in 68.57% of cases they were discharged from the unit. The mean score from APACHE II was 25.41 (sd=7.43) and NAS was 73.59 (sd=15.68) points. The comparative analysis of the NAS scores with the demographic and clinical variables showed that patients which died presented the highest mean nursing workloads. The correlation between the mean NAS score and the quantitative variables: age, days in hospital and severity (APACHE II) showed a moderate correlation with the severity (r=0.33; p=0.00) and low and negative correlation with the length of hospitalization (r=-0.27; p=0.02). The only factor associated to the nursing workload in the group of patients studied was their medical condition when discharged. The evaluation of the nursing workload, as well as the factors which influenced it, has been shown to be an essential resource for the managament of intensive care units.
