TL;DR: News has a greater ability to discriminate patients at risk of the combined outcome of cardiac arrest, unanticipated ICU admission or death within 24h of a NEWS value than 33 other EWSs.

TL;DR: There is a need for an accurate measure of surgical outcomes so that hospitals and surgeons can be compared properly regardless of case mix and POSSUM (Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity) provides a more accurate prediction of mortality.

TL;DR: The data confirm antecedents are common before death, cardiac arrest, and unanticipated ICU admission, and the study shows differences in patterns of primary events, the provision of ICU/HDU beds and resuscitation teams, between the UK and ANZ.

TL;DR: A validated, paper-based, aggregate weighted track and trigger system (AWTTS) that could serve as a template for a national early warning score (EWS) for the detection of patient deterioration is developed and demonstrated that its performance for predicting mortality (within a range of timescales) is superior to all other published AWTTSs.

TL;DR: The previously published POSSUM predictor equation for mortality performed badly when tested using a standard test of goodness of fit for logistic regression and must be modified.
