The nursing workload consists of the time spent by the nursing staff to perform the activities for which they are responsible, whether directly or indirectly related to patient care. The aim of this study was to evaluate the nursing workload in an adult intensive care unit at a university hospital using the Nursing Activities Score (NAS) instrument.
A longitudinal, prospective study that involved the patients admitted to the intensive care unit of a university hospital between March and December 2008. The data were collected daily to calculate the NAS, the Acute Physiology and Chronic Health Evaluation (APACHE II), the Sequential Organ Failure Assessment (SOFA) and the Therapeutic Intervention Scoring System (TISS-28) of patients until they left the adult intensive care unit or after 90 days of hospitalization. The level of significance was set at 5%.
In total, 437 patients were evaluated, which resulted in an NAS of 74.4%. The type of admission, length of stay in the intensive care unit and the patients' condition when leaving the intensive care unit and hospital were variables associated with differences in the nursing workload. There was a moderate correlation between the mean NAS and APACHE II severity score (r=0.329), the mean organic dysfunction SOFA score (r=0.506) and the mean TISS-28 score (r=0.600).
We observed a high nursing workload in this study. These results can assist in planning the size of the staff required. The workload was influenced by clinical characteristics, including an increased workload required for emergency surgical patients and patients who died.

To describe a single center experience involving the administration of colistin to treat nosocomial infections caused by multidrug-resistant Gram-negative bacteria and identify factors associated with acute kidney injury and mortality.
This retrospective longitudinal study evaluates critically ill patients with infections caused by multidrug-resistant Gram-negative bacteria. All adult patients who required treatment with intravenous colistin (colistimethate sodium) from January to December 2008 were considered eligible for the study. Data include demographics, diagnosis, duration of treatment, presence of acute kidney injury and 30-day mortality.
Colistin was used to treat an infection in 109 (13.8%) of the 789 patients admitted to the intensive care unit. The 30-day mortality observed in these patients was 71.6%. Twenty-nine patients (26.6%) presented kidney injury prior to colistin treatment, and six of these patients were able to recover kidney function even during colistin treatment. Twenty-one patients (19.2%) developed acute kidney injury while taking colistin, and 11 of these patients required dialysis. The variable independently associated with the presence of acute kidney injury was the Sequential Organ Failure Assessment at the beginning of colistin treatment (OR 1.46; 95%CI 1.20-1.79; p<0.001). The factors age (OR 1.03; 95%CI 1.00-1.05; p=0.02) and vasopressor use (OR 12.48; 95%CI 4.49-34.70; p<0.001) were associated with death in the logistic-regression model.
Organ dysfunction at the beginning of colistin treatment was associated with acute kidney injury. In a small group of patients, we were able to observe an improvement of kidney function during colistin treatment. Age and vasopressor use were associated with death.
