Review of Early Warning Score in preventing sudden critical illness and death
Ugeskr Læger 2018;180:V02180135
Early Warning Score (EWS) are used extensively to identify patients at risk of deterioration during hospital admission. The validation of EWS has primarily focused on investigating predictive validity, i.e. the association between EWS and severe adverse events. Few studies have tested, whether EWS work in the clinical setting, and if it prevents severe adverse events from occurring. Many of these studies have methodological limitations, and their clinical relevance could be questioned. Currently, there is limited evidence to support, that the implementation of EWS reduces the occurrence of severe adverse events.
