There are many electronic triage algorithms founded in the literature for detect the emergency level of the patients. But which one are really used in the hospitals and clinics nowdays?
In the United Kingdom, healthcare facilities tend to use the National Early Warning Score 2 (NEWS2) (You can find the details at: https://www.rcplondon.ac.uk/projects/outputs/national-early-warning-score-news-2) to classify acute illness. This is also used by the ambulance service (EMS), often in an electronic format, as part of the electronic documentation ambulance crews and Paramedics complete.
In our Hospital we have implemented the Manchester triage system with very good results. From 51 reasons of consultation and through some questions addressed in a diagram. That is, according to the answer yes / no, classification occurs, with 5 severity levels. It also has a digital version.
