Limitations in validating emergency department triage scales

Triage is a tool developed to identify the severely ill patients in a setting challenged with overcrowding and scarce resources [1–3].

Their assigned triage priority was compared with rate of hospitalization and resource utilization.

Validity parameters were sensitivity, specificity, positive and negative predictive value, and percentage of over- and undertriage.

Four different five-level triage systems are internationally accepted.

The Australasian Triage Scale (ATS, Australasia) allows categorization based on symptoms using specific descriptors.

Interrater agreement and accuracy of the triage ratings were calculated from triage performed by nurses on written case scenarios. During the study period, 1171 patients arrived at the hospital for emergency assessment.

A total of 790 patients (67 %) were triaged and included in the study.

Der „emergency severity index“ (ESI, USA) schließt primär akut lebensbedrohliche oder schwere Krankheitsbilder aus und kategorisiert dann nach zu erwartendem Ressourcenbedarf.

Ziel aller Triagesysteme ist primär die Reduktion der Krankenhausmortalität.

The RETTS-p combines presenting symptoms with measurements of vital parameters using emergency signs and symptoms cards.
