Reliability and Accuracy of the Pediatric Swiss Emergency Triage Scale-the SETSped Study

Background and ImportanceThe Swiss Emergency Triage Scale (SETS) is an adult triage tool used in several emergency departments. It has been recently adapted to the pediatric population but, before advocating for its use, performance assessment of this tool is needed.ObjectivesThe purpose of this study was to assess the reliability and the accuracy of the pediatric version of the SETS for the triage of pediatric patients.Design, Setting, and ParticipantsThis study was a cross-sectional study among a sample of emergency triage nurses (ETNs) exposed to 17 clinical scenarios using a computerized simulator.Outcome Measures and AnalysisThe primary outcome was the reliability of the triage level performed by the ETNs. It was assessed using an intraclass correlation coefficient.Secondary outcomes included accuracy of triage compared with expert-based triage levels and factors associated with accurate triage.Outcome Measures and AnalysisThe primary outcome was the reliability of the triage level performed by the ETNs. It was assessed using an intraclass correlation coefficient.Secondary outcomes included accuracy of triage compared with expert-based triage levels and factors associated with accurate triage.Main ResultsEighteen ETNs participated in the study and completed the evaluation of all scenarios, for a total of 306 triage decisions. The intraclass correlation coefficient was 0.80 (95% confidence interval, 0.69-0.91), with an agreement by scenario ranging from 61.1% to 100%. The overall accuracy was 85.8%, and nurses were more likely to undertriage (16.0%) than to overtriage (4.3%). No factor for accurate triage was identified.ConclusionsThis simulator-based study showed that the SETS is reliable and accurate among a pediatric population. Future research is needed to confirm these results, compare this triage scale head-to-head with other recognized international tools, and study the SETSped in real-life setting.
