Severity indexes of blunt trauma victims in intensive therapy: prediction capacity for mortality.

Objective: To identify the predictive capacity for mortality of the indexes Revised Trauma Score, Rapid Emergency Medicine Score, modified Rapid Emergency Medicine Score, and Simplified Acute Physiology Score III in blunt trauma victims hospitalized in an intensive care unit and compare their performance.

Method: Retrospective cohort of patients with blunt trauma in an intensive care unit from medical records. Receiver Operating Characteristic and a 95% confidence interval of the area under the curve were analyzed to compare results.

Model to estimate the nursing workload required by trauma victims on intensive care unit discharge.

Aim: To validate a model to estimate the nursing workload required by trauma victims on intensive care unit (ICU) discharge.

Background: Identifying a reliable model of nursing workload measurement that can assist professionals.

Methods: A prospective cohort study conducted in 2010 (first phase) and 2015 (second phase) with 342 trauma victims admitted into the ICU of four hospitals located in São Paulo, Brazil.

Pulse Pressure and Mortality Risk in Critically Ill Patients.

Background: Pulse pressure is a hemodynamic variable easily measured in the intensive care unit.

Objective: To investigate whether pulse pressure is an independent risk factor for mortality in intensive care unit patients.

Methods: A retrospective cohort study was carried out in Brazil.
