Acute deterioration among hospitalised patient can result in serious adverse events like cardiac arrest, unexpected death or unanticipated intensive care unit (ICU) admission. Most events are preceeded by deteriorating vital signs, and potentially avoidable. To detect and treat hospitalised at-risk patients early an early warning score (EWS) was introduced at the investigator site. EWS measures of a number of physiological parameters that are aggregated to a common score, that directs monitoring frequency, clinical interventions and competency of the provider. Patients with low scores (0 - 1) are monitored every 12th hour and seldom experience serious adverse events. The optimal monitoring frequency for this group is unknown, and presently based on a compromise between patient safety and work load issues. The aim of the present study is to explore if an 8 hourly monitoring interval (intervention) is correlated with a better outcome than 12 hour intervals (control), based on the number of patients that deteriorate to a higher EWS 24 hours after hospital admission in each group.
