<qa>  What is the most accurate triage system in triaging patients?Formalised triage systems are frequently used in trauma care in high income countries. Such systems are believed to have improved trauma care and hence trauma patient outcome. However, more than 90 per cent of all deaths due to trauma occur in low- and middle income countries, where formalised triage systems are uncommon to non-existing. Formalized triage systems may help strengthen trauma care in low - and middle income countries. However, research is lacking on whether algorithms or clinicians perform the most accurate in triaging patients.
