Objective: Nosocomial infections contribute to hospital-associated morbidity and mortality. The aim of this study is to identify the role of the Acute Physiology And Chronic health Evaluation (APACHE) II, III and Injury Severity Scale (ISS) as independent predictors fo nosocomial infections in blunt trauma patients admitted to the intensive care unit (ICU).
Methods: A retrospective chart review of 299 blunt trauma patients admitted to the ICU was conducted by one trauma surgeon. Demographic data and incidence of nosocomial infections were recorded. Multivariate logistic regression analysis was used to determine variables that were predictors of the occurrence of nosocomial infections.
Results: Age, presence of intubation, ICU length of stay, APACHE II, III and ISS were related to the presence of noscomial infections. However, only the ICU length of stay was an independent predictor of a nosocomial infection, with an odd ratio of 1.16 (95% confidential interval 1.10 – 1.22).APACHE II, III and ISS scores were linearly correlated with length of ICU stay. Age, presence of endotracheal intubation and length of ICU stay became independent predictors when the infection were focused on nosocomial pneumonia.
Conclusions: APACHE II, III and ISS scores were not good predictors of nosocomial infections in blunt trauma patients admitted to the ICU, but these scores have modest correlations with the duration of stay in ICU. |
