Statistical analysis involving the determination of prognosis factors for the nutritional state of the severely ill patient at discharge

Abstract

An unbalanced cases and control study, nested in a cohort, of patients assisted in the Intensive and Intermediate Care Unit of "Saturnine Lora Torres" Teaching Provincial Clinical Surgical Hospital in Santiago de Cuba was carried out, with the double purpose of identifying the prognosis factors that impacted in the nutritional state at their discharge and also to evaluate the usefulness of the statistical analysis for the identification of these factors. In the processing of data two techniques were used: the logistical regression analysis, with which the mechanical ventilation, the intrahospital infection, the surgical treatment and the prolonged stay were identified as bad prognosis factors; and the statistical analysis, with which the nutritional state at admission, the intrahospital infection, the mechanical ventilation and the prolonged stay were detected. The statistical analysis showed a higher probability of identifying prognosis factors, with good results in the effectiveness calculated indicators.
