CHroniSense National Early Warning Score Study

The objective of the Polso™ feasibility study is to demonstrate the suitability of Polso™ as a data acquisition and processing platform by comparison with the conventional British version of EWS (UK-NEWS) on aggregate and on each individual parameter score. Although in a full NEWS system, the frequency of testing is determined by the score itself, this aspect will not be evaluated, in the event that a divergence of scores would complicate clinical evaluation and correspondence of readings. In addition, good clinical practice calls for patient care to be fully motivated by the NEWS currently in use, as opposed to the experimental Polso™. Therefore, this compromise will be made, which will still permits system evaluation.
