A Prospective Study of Comparison of APACHE-IV SAPS-II Scoring Systems and Calculation of Standardised Mortality Rate in Severe Sepsis and Septic Shock Patients

摘要

>Context: Severe sepsis and septic shock are major causes of mortality in the Intensive Care Unit (ICU) Illness Scoring Systems can help in the prediction of outcome of these patients.>Aim: To calculate and compare APACHE-IV and SAPS-II Scoring Systems along with calculation of Standardised Mortality Rate (SMR) in patients of severe sepsis and septic shock in the ICU.>Study Design: Observational-analytical prospective study.>Materials and Methods: The study was conducted on 84 patients with severe sepsis and septic shock admitted to the Medical ICU of a tertiary care teaching hospital.>Results: Mean of Predicted Mortality Rate (PMR) for APACHE-IV was 37.85% and for SAPS-II, it was 72.36% which shows that APACHE-IV had under-predicted overall mortality while SAPS-II had over-predicted overall mortality of patients with severe sepsis and septic shock. Standardised Mortality Rate for APACHE-IV was 1.60 and for SAPS-II, it was 0.83.>Conclusion: Predicted Mortality of APACHE-IV and SAPS-II Scoring Systems did not correlate with the observed mortality for patients with severe sepsis and septic shock.
