Validity of the Manchester Triage System in emergency patients receiving life-saving intervention or acute medical treatment-A prospective observational study in the emergency department.

Rationale, Aims, And Objectives: The spectrum of cases seen by emergency departments ranges from minor illnesses or injuries to complex diseases with high mortality. Some patients require life-saving interventions (LSIs) or therapeutic treatment for an acute illness to prevent an expected imminent life-threatening condition immediately upon arrival. No published study has evaluated the validity of the Manchester Triage System (MTS) in the context of immediate LSI or acute emergency treatment (AET).
