Clinical Trial Summary

For patients admitted with COVID-19 infection, it is often difficult to predict if or when their clinical condition will deteriorate. However subtle changes in vital signs are usually present 8 to 24 hours before a life-threatening event such as respiratory failure leading to ICU admission, or unanticipated cardiac arrest. Such adverse trends in clinical observations can be missed, misinterpreted or not appreciated as urgent. New continuous and wearable 24/7 clinical vital parameter monitoring systems offer a unique possibility to identify clinical deterioration before patients condition progress beyond the point-of-no-return, where adverse events are inevitable. The primary aim of this study is to test the effect of continuous wireless vital signs monitoring with generation of real-time alerts through a purpose-built GUI, compared to standard EWS monitoring on the cumulative duration of any severely deviating vital signs
