Abstract

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.

Keywords: APACHE-IV; SAPS-II; Septic shock; Severe sepsis; Standardised mortality rate.
