Abstract
Background: The advantages of Acute Physiology and Chronic Health Evaluation (APACHE II) score include its ability to prognosticate sepsis with a single assessment at 24 hours and its components being routine parameters being monitored in the ICU. APACHE II is a severity-of-disease classification system, one of several ICU scoring systems. It is applied within 24hours of admission of a patient to an ICU and an integer score from 0-71 is computed based on several measurements. Higher scores correspond to more severe disease and a higher mortality. A study was designed to evaluate performance of APACHE II score in prediction of mortality risk, as well as in determination of model validity in critically ill patients.Methods: All the patients who were admitted in ICU were included. APACHE II score is calculated on the 1st or 2nd day of admission in the ICU and it is collected on odd & even days of the patients stay in intensive care unit (ICU). The following data were collected for each patient like age, name, sex, chronic health status, physiological measurements, laboratory investigations etc.Results: No significant difference was observed between Odd and Even groups with pretest mean APACHE II scores (t=-0.5750, p=0.5653) at 5% level of significance. No significant difference was observed between Odd and Even groups with posttest mean APACHE II scores (t=-0.1278, p=0.8983) at 5% level of significance. No significant difference was observed between Odd and Even groups with change in mean APACHE II scores from pretest to posttest (t=0.0639, p=0.9491) at 5% level of significance. A significant difference was observed between pretest and posttest in APACHE II scores in total samples (t=7.0269, p=0.0001) at 5% level of significance. A significant difference was observed between pretest and posttest in APACHE II scores in odd group (t=4.9266, p=0.0026) at 5% level of significance. A significant difference was observed between pretest and posttest in APACHE II scores in even group (t=4.6309, p=0.0036) at 5% level of significance.Conclusions: Acute physiology and Chronic Health Evaluation (APACHEII) score assessed at 24 hours after admission is able to predict morbidity, mortality. The presence of a physiotherapist in the intensive care unit contributes decisively to the early recovery of the patient, reducing mechanical ventilation support need, number of hospitalization days, and incidence of respiratory infection and risk of mortality.
