1. Standardized Mortality Ratio Israt sadia MBBS, Mphil . Infection Control Departement Labaid hospital

2. Standardized Mortality Ratio It is the ratio of the Observed or actual mortality and the predicted mortality for a specified time period. It requires an estimate of predicted mortality rate using a scoring system like APACHE, SOFA, SAPS,MPM or PRISM . Actual death in ICU/ Predicted deaths in ICU x100 = SMR < 1.0 indicates there were fewer than expected deaths in the study population SMR = 1.0 indicates the number of observed deaths equals the number of expected deaths in the study population SMR >1.0 indicates there were more than expected deaths in the study population (excess deaths)

3. APACHE score Acute Physiologic Assessment and Chronic Health Evaluation II (APACHE II) score introduced in 1985. https://www.mdcalc.com/apache-ii-score#evidence
