A longitudinal, retrospective registry-based validation study of RETTS©, the Swedish adult ED context version.

Background: Triage and triage related work has been performed in Swedish Emergency Departments (EDs) since the mid-1990s. The Rapid Emergency Triage and Treatment System (RETTS©), with annual updates, is the most applied triage system. However, the national implementation has been performed despite low scientific foundation for triage as a method, mainly related to the absence of adjustment to age and gender.

An updated national survey of triage and triage related work in Sweden: a cross-sectional descriptive and comparative study.

Background: Triage and triage related work has been performed in Swedish Emergency Departments (EDs) since the mid-1990s. According to two national surveys from 2005 to 2011, triage was carried out with different triage scales and without guidelines or formal education. Furthermore, a review from 2010 questioned the scientific evidence for both triage as a method as well as the Swedish five level triage scale Medical Emergency Triage and Treatment System (METTS); nevertheless, METTS was applied in 65% of the EDs in 2011.

A descriptive study of registered nurses' application of the triage scale RETTS©; a Swedish reliability study.

Background: From a patient safety perspective, it is of great importance that decision support systems such as triage scales are evidence based. In the most recent national survey, the majority of Swedish Emergency Departments (EDs) apply the Swedish triage scale known as the Medical Emergency Triage Treatment Scale (METTS), subsequently renamed the Rapid Emergency Triage Treatment Scale (RETTS©). Despite national widespread implementation, there has been limited research on METTS/RETTS©.
