A low proportion of undertriage validates the new West coast system for triage-Paediatric.

Abstract

There is a lack of studies on paediatric triage systems. This study aimed to evaluate patient safety of the Gothenburg-developed paediatric triage system West Coast System for Triage-Paediatric (WEST-P). This study was performed at the paediatric emergency department in Gothenburg, Sweden, October 2020 to April 2021. Included patients were double-triaged with the WEST-P, and the established Rapid Emergency Triage and Treatment System-Paediatrics (RETTS-p). We compared the level of urgency between both systems to identify potentially undertriaged patients. Also, we assessed the patient safety according to clinical assessment at presentation, and pre-defined criteria. This study included 2290 (23%) of triaged patients (44% girls, median age: 5.0 years) during the study period. A higher number of patients triaged to low urgency in WEST-P compared to RETTS-p (p < 0.0001) was observed, and 497 cases with low WEST-P and high RETTS-p urgencies identified. Of these, 29 had a clinical assessment indicating high urgency. After patient safety assessment, seven (0.4%) were determined undertriaged by the new triage system WEST-P. Our findings demonstrate a low risk of undertriage in the new WEST-P. Thus, the WEST-P has a high degree of patient safety when used in a paediatric emergency department.
