Early warning scores to predict noncritical events overnight in hospitalized medical patients: a prospective case cohort study.

This study found that two early warning scores – the Modified Early Warning Score (MEWS) and the National Early Warning Score (NEWS) – can predict patients at risk of deterioration and who will need to be seen by a physician overnight. The authors conclude that use of such early warning scores may be useful for improving handoffs and resource allocation for overnight care.
