Chiu YD, et al. - In view of recently mandated use of the National Early Warning Score of vital signs in all acute hospital trusts in the UK by NHS England, researchers conducted a multicentre UK study of 13,631 patients discharged from intensive care after risk-stratified cardiac surgery in four centers. Postoperative National Early Warning Score vital signs were electronically collected using VitalPAC in all of these centers. Analyzing 540,127 sets of vital signs, they generated a logistic score, the discrimination of which was compared with the national additive score for the composite outcome of: in-hospital death; cardiac arrest; or unplanned intensive care admission. Discrimination by the logistic score vs the additive score was significantly better. This indicates the superiority of the proposed logistic Early Warning Score to the current National Early Warning Score at discriminating patients who had an event after cardiac surgery from those who did not.
