Numerous limitations are embedded in the process of validating triage scales.
Methods of triage scale validation in developed countries may not be appropriate and repeatable in developing countries.
The Delphi method, a consensual validation process, is advanced as a more appropriate alternative for validating triage scales in developing countries.
ABSTRACT: Introduction: The implementation of triage systems seeks to aid patient organisation in order to assure smooth patient flow.
To examine whether current validation methods of emergency department triage scales actually assess the instrument's validity.
Optimal methods of emergency department triage scale validation are examined in developed countries and their application to developing countries is considered.
Conclusions The Manchester triage system has moderate validity in paediatric emergency care.
It errs on the safe side, with much more over-triage than under-triage compared with an independent reference standard for urgency.
This review included quantitative and qualitative research investigating the reliability and validity of the Manchester Triage System for the broad population of adults and children visiting the emergency department.
