This application will calculate the Simple Clinical Score (SCS) for a patient, giving the following information: 1. SCS risk stratification, 2. Predicted 30 day mortality, 3. Median length of hospital stay, 4. 30 day re-admission rate. The Simple Clinical Score is based on points awarded for 16 independent predictors of mortality as identified by J Kellett & B Deane (1): Age, Systolic Blood Pressure, Pulse Rate > Systolic Blood Pressure, Temperature, Respiratory Rate, Oxygen Saturation.
