Prediction of Outcome in ICU Patients Using SAPS II Scoring-A Prospective Study

Abstract

Introduction: Since 1981, several severity scores have been proposed for ICU patients. The first ones were acute physiology and chronic health evaluation(APACHE, APACHEII),Simplified acute physiology score (SAPS); later, mortality probability model(MPM) and APACHE III were introduced. The SAPS II scoring system, have been used as a method for converting the score to a probability of hospital mortality.The present prospective study is designed to predict the ICU outcome in medical ICU patients. Objective of the Study: To predict the mortality and morbidity of the patients admitted in ICU for various emergencies using SAPS II scoring system and correlate it with the outcome of the patient on discharge. Materials and Methods: The study prospective type, data was obtained from the patients admitted to ICU ,SAPS II scoring was given and were followed up till they got discharged to assess the outcome .Results:45 patients were studied the total mortality was 26.6%. The SAPS II Scores of the patients and the number of deaths in the different groups are given in table below. The chi-square value was 23.04, df= 6with a p + 0.0007 and this study is well within the p value of 0.05, hence it is significant which means the higher the score the more is the risk of morbidity and mortality, when score is >50 there is increased risk of morbidity and mortality, when score is >50 there is increased risk of mortality. Conclusion:The present study imposes on the following conclusions -SAPS II scoring is useful in predicting the ICU outcome of patients admitted in the ICU even when the primary diagnosis is not specified.
