Accuracy of triage systems for mass casualty incidents in live simulations - a systematic review.
Danish Medical Journal · 2023-10-06 · Systematic review
Abstract
INTRODUCTION: In mass casualty incidents, insufficient triage may lead to increased morbidity and mortality due to delayed evacuation and treatment of the most critically injured patients. We report current litterature findings on accuracy of primary prehospital triage systems for mass casualty incidents in full-scale live simulations and map the challenges that lie ahead for finding the most accurate triage system. METHODS: This study was registered with PROSPERO ID: CRD42018091889. We searched the databases EMBASE, MEDLINE, Central, Web of Science, Reference lists, Scopus, ClinicalTrials.gov and Google Scholar. We included primary triage systems, studies reporting accuracy or outcomes convertible to accuracy and studies performed in full-scale live simulations. We excluded studies using paediatric, chemical, biological, radiological or nuclear populations or triage systems. Bias rating was based on a modified version of the QUADAS-2. RESULTS: A total of 15 studies were included. Six of 41 existing triage methods were tested. The studies showed substantial heterogeneity in both study characteristics and findings. Different reference standards were applied and most were based on author-defined triage categories. All studies carried an unclear-to-high risk of bias. Therefore, no quantitative comparisons were made. CONCLUSION: In general, the studies suffered from substantial heterogeneity and risk of bias. A standardised protocol for future live simulations is needed to encourage consistent and comparable data collection. We identified some of the most important topics to address in such a protocol.
