HERNANDEZ AMADOR, José Fernando et al. Early warning scoring systems. Early Warning Scores (EWS). Acta méd. Grupo Ángeles [online]. 2019, vol.17, n.3, pp.252-258.  Epub Feb 11, 2022. ISSN 1870-7203.

Since Morgan’s 1997 early warning score description, more than 100 algorithms have been implemented all around the world, only being universally applied in the United Kingdom healthcare services as suggested by the NICE from 2007. Always in the setting of the emergency response team (ERT) a number of investigators have found contrary experiences; some of the scores have been validated, some compared one to one, some improved and some standardized, all of them obtaining less cardiac arrest and less blue code activation; being the end proposal of the algorithm to prevent medical intervention delay or get an appropriate reference to the sought after medical care area. The Early Warning Scores (EWS) represent a healthcare service need and a simple algorithm that doesn’t increase the workload but offers the timely identification of trigger vital sign that surely need medical assessment by the ERT and, if needed, transfer to a more advanced care unit so we can finally avoid the failure to rescue. So far, clinical recommendation is to choose a Score by the resources and variables in the healthcare system and once implemented follow a high level of adherence and make timely specific interventions to in this way improve patient prognosis.
